WebDriver

WebDriver manipula um navegador nativamente, aprenda mais sobre isso.

O WebDriver manipula um navegador nativamente, como um usuário faria, seja localmente ou em uma máquina remota usando o servidor Selenium, marca um salto em termos de automação do navegador.

Selenium WebDriver refere-se a ambas as ligações de linguagem e as implementações do código de controle do navegador individual. Isso é comumente referido como apenas WebDriver.

Selenium WebDriver é uma recomendação W3C

  • WebDriver é projetado como uma interface de programação simples e mais concisa.

  • WebDriver é uma API compacta orientada a objetos.

  • Ele manipula o navegador de forma eficaz.

1 - Começando

Se você é novo no Selenium, nós temos alguns recursos que podem te ajudar a se atualizar imediatamente.

Selenium suporta automação de todos os principais navegadores do mercado por meio do uso do WebDriver. WebDriver é uma API e protocolo que define uma interface de linguagem neutra para controlar o comportamento dos navegadores da web. Cada navegador é apoiado por uma implementação WebDriver específica, chamada de driver. O driver é o componente responsável por delegar ao navegador, e lida com a comunicação de e para o Selenium e o navegador.

Essa separação é parte de um esforço consciente para que os fornecedores de navegadores assumam a responsabilidade pela implementação de seus navegadores. Selenium faz uso desses drivers de terceiros sempre que possível, mas também fornece seus próprios drivers mantidos pelo projeto para os casos em que isso não é uma realidade.

A estrutura do Selenium une todas essas peças por meio de uma interface voltada para o usuário que permite aos diferentes back-ends de navegador serem usados de forma transparente, permitindo a automação entre navegadores e plataformas cruzadas.

A configuração do Selenium é bastante diferente da configuração de outras ferramentas comerciais. Para usar Selenium em seu projeto de automação, você precisa instalar as bibliotecas de linguagem para sua linguagem de escolha. Além disso, você precisará dos binários WebDriver para os navegadores que você deseja automatizar e executar testes.

A instalação do Selenium é dividida nas etapas:

  1. Instalando a biblioteca Selenium para sua linguagem de programação escolhida.
  2. Configure o driver para o navegador para automatizar o navegador (ex. GeckoDriver para Firefox).
  3. (Opcional) Escolha e configure Selenium Grid se você quiser tornar seus testes escaláveis.

Se você deseja iniciar com ferramenta low-code / gravação e reprodução, por favor veja: Selenium IDE

Depois de completar as etapas de configuração, você pode executar o snippet de codigo em starting page na documentação. Então siga para seção WebDriver para aprender mais sobre automação de navegadores com Selenium.

1.1 - Instalando bibliotecas do Selenium

Configurando a biblioteca Selenium para sua linguagem de programação favorita.

Primeiro você precisa instalar as bibliotecas Selenium para seu projeto de automação. O processo de instalação de bibliotecas depende da linguagem que você escolher usar.

Requisitos por linguagem

Veja a mínima versão do Java suportada aqui.

A instalação da biblioteca Selenium para Java é feita a partir de uma build tool.

Maven

Especifique a dependência no pom.xml do seu projeto.

        <dependency>
            <groupId>org.slf4j</groupId>
            <artifactId>slf4j-api</artifactId>
            <version>1.7.36</version>
        </dependency>

Gradle

Especifique a dependência no build.gradle do seu projeto como testImplementation:

    testImplementation 'org.seleniumhq.selenium:selenium-java:4.8.0'

A mínima versão suportada do Python para cada versão do Selenium pode ser encontrada em Supported Python Versions no PyPi

Existe muitas formas diferentes de instalar Selenium.

Pip

pip install selenium

Download

Como uma alternativa você pode baixar o código fonte PyPI (selenium-x.x.x.tar.gz) e instalar usando setup.py:

python setup.py install

Exigir em um projeto

Para usar em um projeto, adicione no arquivo requirements.txt.

selenium==4.8.2

Uma lista com todos os frameworks suportados para cada versão do Selenium pode ser encontrada em Nuget

Existe algumas opções para instalar o Selenium.

Packet Manager

Install-Package Selenium.WebDriver

.NET CLI

dotnet add package Selenium.WebDriver

CSProj

No arquivo csproj do seu projeto, especifique a dependência como PackageReference no ItemGroup:

      <PackageReference Include="Selenium.WebDriver" Version="4.8.1" />

Considerações adicionais

Outras observações para usar o Visual Studio Code (vscode) e C#

Instale a versão compatível do .NET SDK conforme a seção acima. Instale também as extensões do vscode (Ctrl-Shift-X) para C# e NuGet. Siga as instruções aqui para criar e rodar o seu projeto de “Hello World” no console usando C#.

Você também pode criar um projeto inicial do NUnit usando a linha de comando dotnet new NUnit. Certifique-se de que o arquivo %appdata%\NuGet\nuget.config esteja configurado corretamente, pois alguns desenvolvedores relataram que ele estará vazio devido a alguns problemas. Se o nuget.config estiver vazio ou não estiver configurado corretamente, as compilações .NET falharão para projetos que estiverem usando Selenium. Adicione a seguinte seção ao arquivo nuget.config se esse estiver vazio:

<configuration>
  <packageSources>
    <add key="nuget.org" value="https://api.nuget.org/v3/index.json" protocolVersion="3" />
    <add key="nuget.org" value="https://www.nuget.org/api/v2/" />   
  </packageSources>
...

Para mais informações sobre nuget.config clique aqui. Você pode ter que customizar nuget.config para atender às suas necessidades.

Agora, volte para o vscode, aperte Ctrl-Shift-P, e digite “NuGet Add Package”, e adicione os pacotes necessários para o Selenium como o Selenium.WebDriver. Aperte Enter e selecione a versão. Agora você pode usar os exemplos da documentação relacionados ao C# com o vscode.

Você pode ver a minima versão suportada do Ruby para cada versão do Selenium em rubygems.org

O Selenium pode ser instalado de duas formas diferentes.

Instalação manual

gem install selenium-webdriver

Adicione para o gemfile do projeto

gem 'selenium-webdriver', '= 4.8.0'

Você pode encontrar a mínima versão suportada do Node para cada versão do Selenium na seção Node Support Policy no site npmjs

Selenium é normalmente instalado usando npm.

Instalação local

npm install selenium-webdriver

Adicione ao seu projeto

No package.json do seu projeto, adicione os requisitos em dependencies:

        "selenium-webdriver": "^4.8.1"
Use as ligações Java para Kotlin.

Próximo passo

Instale os drivers do navegador

1.2 - Instalando drivers de navegadores

Configurando seu navegador para ficar preparado para ser automatizado.

Através do WebDriver, o Selenium suporta todos os principais navegadores do mercado como Chrome/Chromium, Firefox, Internet Explorer, Edge e Safari. Sempre que possível, o WebDriver conduz o navegador usando o suporte integrado do navegador para automação.

Como todas as implementações do driver, exceto a do Internet Explorer, são fornecidas pelos próprios desenvolvedores dos navegadores, elas não estão incluídas na distribuição padrão do Selenium. Esta seção explica os requisitos básicos para você começar a usar os diferentes navegadores.

Leia mais sobre opções avançadas para iniciar um driver na nossa documentação de configuração de driver.

Quatro maneiras diferentes de usar os drivers

1. Gerenciador Selenium (Beta)

Selenium v4.6

Selenium Manager helps you to get a working environment to run Selenium out of the box (no additional downloads! no additional configurations!). Selenium Manager attempts to obtain the most correct driver for any browser supported by Selenium in a performant way. Selenium Manager is currently “opt-in,” which means that it is only used if code would otherwise fail. That means if you manage drivers by one of the approaches below, Selenium Manager will not be used.

2. Software de gerenciamento de Driver

Before Selenium Manager was created, many users turned to other projects to automatically manage their drivers. Most of the functionality of these libraries exists natively in the latest version of Selenium.

If you can’t use Selenium Manager because you are using an older version of Selenium (please upgrade), or need an advanced feature not yet implemented by Selenium Manager, you might try one of these tools:

3. A variável de ambiente PATH

Note: we highly recommend removing drivers from PATH and using Selenium Manager if possible.

Esta opção requer primeiro o download manual do driver (Vejá a sessão de Consulta de referencia rápida para links).

Esta é uma opção flexível para alterar a localização dos drivers sem precisar atualizar seu código e funcionará em várias máquinas sem exigir que cada máquina coloque os drivers no mesmo lugar.

Você pode colocar os drivers em um diretório que já está listado em PATH, ou você pode colocá-los em um diretório e acrescenta-lo ao PATH.

Para ver quais diretórios já estão no PATH, abra o Terminal e execute:

echo $PATH

Se o local do seu driver ainda não estiver em um diretório listado, você pode adicionar um novo diretório ao PATH:

echo 'export PATH=$PATH:/path/to/driver' >> ~/.bash_profile
source ~/.bash_profile

You can test if it has been added correctly by checking the version of the driver:

chromedriver --version

Para ver quais diretórios já estão no PATH, abra o Terminal e execute:

echo $PATH

Se o local do seu driver ainda não estiver em um diretório listado, você pode adicionar um novo diretório ao PATH:

echo 'export PATH=$PATH:/path/to/driver' >> ~/.zshenv
source ~/.zshenv

You can test if it has been added correctly by checking the version of the driver:

chromedriver --version

Para ver quais diretórios já estão no PATH, abra o Prompt de Comando e execute:

echo %PATH%

Se o local do seu driver ainda não estiver em um diretório listado, você pode adicionar um novo diretório ao PATH:

setx PATH "%PATH%;C:\WebDriver\bin"

You can test if it has been added correctly by checking the version of the driver:

chromedriver.exe --version

Se o seu PATH estiver configurado corretamente como acima, you will see the version printed like:

ChromeDriver 111.0.5563.64 (c710e93d5b63b7095afe8c2c17df34408078439d-refs/branch-heads/5563@{#995})

If it is not found, you’ll see:

chromedriver.exe : The term 'chromedriver.exe' is not recognized as the name of a cmdlet, function, script file, or operable program

4. Localização definida no código

Note: we highly recommend not directly referencing the drivers and using Selenium Manager if possible.

Semelhante à opção 3 acima, você precisará baixar manualmente o driver (Vejá a sessão de Consulta de referencia rápida para links). Especificar a localização no próprio código tem a vantagem de você não precisar se preocupar em descobrir variáveis de ambiente no seu sistema, mas tem a desvantagem de tornar o código muito menos flexível.

System.setProperty("webdriver.chrome.driver","/path/to/chromedriver");
ChromeDriver driver = new ChromeDriver();
from selenium.webdriver.chrome.service import Service
from selenium import webdriver

service = Service(executable_path="/path/to/chromedriver")
driver = webdriver.Chrome(service=service)
var driver = new ChromeDriver(@"C:\WebDriver\bin");
service = Selenium::WebDriver::Service.chrome(path: '/path/to/chromedriver')
driver = Selenium::WebDriver.for :chrome, service: service
const {Builder} = require('selenium-webdriver');
const chrome = require('selenium-webdriver/chrome');

const service = new chrome.ServiceBuilder('/path/to/chromedriver');
const driver = new Builder().forBrowser('chrome').setChromeService(service).build();
import org.openqa.selenium.chrome.ChromeDriver

fun main(args: Array<String>) {
    System.setProperty("webdriver.chrome.driver", "/path/to/chromedriver")
    val driver = ChromeDriver()
}

Próximo Passo

Programando o seu primeiro script Selenium

1.3 - Programe o seu primeiro script Selenium

Instruções passo a passo para programar um script Selenium

Assim que você tiver o Selenium instalado e os Drivers instalados, você estará pronto para programar códigos Selenium.

Oito Componentes Básicos

Tudo que o Selenium faz é enviar comandos ao navegador de internet para fazer algo ou solicitar informações dele. A maior parte do que você irá fazer com o Selenium é uma combinação desses comandos básicos:

1. Iniciando uma sessão

Para ter mais detalhes sobre como iniciar uma sessão, leia nossa documentação em driver sessions

        WebDriver driver = new ChromeDriver();
    driver = webdriver.Chrome()
            IWebDriver driver = new ChromeDriver();
    driver = Selenium::WebDriver.for :chrome
      driver = await new Builder().forBrowser('chrome').build();
    fun setupAll() {

2. Agindo no navegador de internet

Nesse exemplo estamos navegando para uma página web.

        driver.get("https://www.selenium.dev/selenium/web/web-form.html");
    driver.get("https://www.selenium.dev/selenium/web/web-form.html")
            driver.Navigate().GoToUrl("https://www.selenium.dev/selenium/web/web-form.html");
    driver.get('https://www.selenium.dev/selenium/web/web-form.html')
      await driver.get('https://www.selenium.dev/selenium/web/web-form.html');

3. Solicitando informação do navegador de internet

Existem diversos tipos de informação sobre o navegador de internet que você pode solicitar, incluindo window handles, tamanho / posição do navegador, cookies, alertas e etc.

        String title = driver.getTitle();
    title = driver.title
            var title = driver.Title;
    title = driver.title
      let title = await driver.getTitle();

4. Estabelecendo uma Estratégia de Espera

Sincronizar o código ao estado atual do navegador é um dos maiores desafios quando se trabalha com o Selenium, fazer isso de maneira bem feita é um tópico avançado.

Essencialmente, você quer ter certeza absoluta de que o elemento está na página antes de tentar localizá-lo e o elemento está em um estado interativo antes de você tentar interagir com ele.

Uma espera implícita raramente é a melhor solução, mas é a mais fácil de demonstrar aqui, então vamos usá-la como um substituto.

Leia mais sobre Estratégias de espera.

        driver.manage().timeouts().implicitlyWait(Duration.ofMillis(500));
    driver.implicitly_wait(0.5)
            driver.Manage().Timeouts().ImplicitWait = TimeSpan.FromMilliseconds(500);
    driver.manage.timeouts.implicit_wait = 500
      await driver.manage().setTimeouts({implicit: 500});

5. Encontrando um elemento

A maioria dos comandos na maior parte das sessões do Selenium são relacionados a elementos e você não pode interagir com um sem o primeiro encontrando um elemento

        WebElement textBox = driver.findElement(By.name("my-text"));
        WebElement submitButton = driver.findElement(By.cssSelector("button"));
    text_box = driver.find_element(by=By.NAME, value="my-text")
    submit_button = driver.find_element(by=By.CSS_SELECTOR, value="button")
            var textBox = driver.FindElement(By.Name("my-text"));
            var submitButton = driver.FindElement(By.TagName("button"));
    text_box = driver.find_element(name: 'my-text')
    submit_button = driver.find_element(tag_name: 'button')
      let textBox = await driver.findElement(By.name('my-text'));
      let submitButton = await driver.findElement(By.css('button'));
    @AfterEach
    fun teardown() {

6. Agindo no elemento

Há apenas um punhado de ações a serem executadas em um elemento, mas você irá usá-las com frequência.

        textBox.sendKeys("Selenium");
        submitButton.click();
    text_box.send_keys("Selenium")
    submit_button.click()
            textBox.SendKeys("Selenium");
            submitButton.Click();
    text_box.send_keys('Selenium')
    submit_button.click
      await textBox.sendKeys('Selenium');
      await submitButton.click();

7. Solicitando informações do elemento

Elementos podem guardar muitas informações que podem ser solicitadas.

        String value = message.getText();
    value = message.text
            var value = message.Text;
    value = message.text
      let value = await message.getText();

8. Encerrando a sessão

Isso encerra o processo do driver, que por padrão também fecha o navegador. Nenhum outro comando pode ser enviado para esta instância do driver.

        driver.quit();
            driver.Quit();
    after(async () => await driver.quit());
        assertEquals("Web form", title)

Juntando tudo

Vamos combinar essas 8 coisas em um script completo com asserções que podem ser executadas por um executor de testes.

Executando Testes

Se você esta usando selenium para realizar testes, você deverá executar seu código usando feramentas para executar testes.

Muitos exemplos de código encontrado nessa documentação podem ser encontrado no nosso repositório de exemplos. Existem múltiplas opções em cada linguagem, mas esta será qual usaremos em nossos exemplos:

// Add instructions
// Add instructions
// Add instructions
// Add instructions

Install Mocha Test runner using below command in your terminal

npm install mocha

and run your tests using below command

mocha firstScript.spec.js
// Add instructions

Próximos Passos

Use o que você aprendeu e construa o seu proprio código Selenium.

À medida que você encontrar mais funcionalidades de que necessita, leia o restante da nossa documentação do WebDriver.

1.4 - Como atualizar para Selenium 4

Interessado no Selenium 4? Veja este guia para realizar o upgrade para a ultima versão!

Atualizar para o Selenium 4 deve ser um processo sem dificuldades se você estiver usando uma das linguagens oficialmente suportadas (Ruby, JavaScript, C#, Python, and Java). Pode haver alguns casos em que alguns problemas podem acontecer, este guia irá ajudar você a resolvê-los. Vamos passar as etapas para atualizar as dependências do seu projeto e entender as depreciações e também as mudanças trazidas pela versão atualizada.

Estas são as etapas que seguiremos para atualizar para o Selenium 4:

  • Preparando nosso código de teste
  • Atualizando as dependências
  • Possíveis erros e mensagens de suspensão de uso

Nota: enquanto as versões do Selenium 3.x estavam sendo desenvolvidas, foi implementado o suporte padrão para W3C WebDriver. Este novo protocolo e o legado JSON Wire Protocol foram suportados. Através da versão 3.11, o código do Selenium passou a ser compátivel com o nível 1 da especificação W3C. A compatibilidade do código W3C na ultima versão do Selenium 3 irá funcionar como esperado na versão 4.

Preparando nosso código de teste

Selenium 4 remove suporte para protocolos legados e usa o W3C Webdriver por padrão. Para a maioria das coisas, essa implementação não irá afetar usuários finais. As maiores exeções são Capabilities e a classe Actions.

Recursos

Se os recursos de teste não forem estruturados para serem compatíveis com W3C, pode fazer com que uma sessão não seja iniciada. Aqui está a lista de recursos padrão do W3C WebDriver:

  • browserName
  • browserVersion (replaces version)
  • platformName (replaces platform)
  • acceptInsecureCerts
  • pageLoadStrategy
  • proxy
  • timeouts
  • unhandledPromptBehavior

Uma lista atualizada de recursos padrão pode ser encontrada aqui: W3C WebDriver.

Qualquer recurso que não esteja incluido na lista acima, precisa ser incluido um prefixo de fornecedor. Isso se aplica aos recursos específicos do navegador, bem como aos recursos específicos do fornecedor da nuvem. Por exemplo, se o seu fornecedor de nuvem usa os recursos build e name para seus testes, você precisa envolvê-los em um bloco cloud: options (verifique com seu fornecedor de nuvem o prefixo apropriado).

Antes

DesiredCapabilities caps = DesiredCapabilities.firefox();
caps.setCapability("platform", "Windows 10");
caps.setCapability("version", "92");
caps.setCapability("build", myTestBuild);
caps.setCapability("name", myTestName);
WebDriver driver = new RemoteWebDriver(new URL(cloudUrl), caps);
caps = {};
caps['browserName'] = 'Firefox';
caps['platform'] = 'Windows 10';
caps['version'] = '92';
caps['build'] = myTestBuild;
caps['name'] = myTestName;
DesiredCapabilities caps = new DesiredCapabilities();
caps.SetCapability("browserName", "firefox");
caps.SetCapability("platform", "Windows 10");
caps.SetCapability("version", "92");
caps.SetCapability("build", myTestBuild);
caps.SetCapability("name", myTestName);
var driver = new RemoteWebDriver(new Uri(CloudURL), caps);
caps = Selenium::WebDriver::Remote::Capabilities.firefox
caps[:platform] = 'Windows 10'
caps[:version] = '92'
caps[:build] = my_test_build
caps[:name] = my_test_name
driver = Selenium::WebDriver.for :remote, url: cloud_url, desired_capabilities: caps
caps = {}
caps['browserName'] = 'firefox'
caps['platform'] = 'Windows 10'
caps['version'] = '92'
caps['build'] = my_test_build
caps['name'] = my_test_name
driver = webdriver.Remote(cloud_url, desired_capabilities=caps)

Depois

FirefoxOptions browserOptions = new FirefoxOptions();
browserOptions.setPlatformName("Windows 10");
browserOptions.setBrowserVersion("92");
Map<String, Object> cloudOptions = new HashMap<>();
cloudOptions.put("build", myTestBuild);
cloudOptions.put("name", myTestName);
browserOptions.setCapability("cloud:options", cloudOptions);
WebDriver driver = new RemoteWebDriver(new URL(cloudUrl), browserOptions);
capabilities = {
  browserName: 'firefox',
  browserVersion: '92',
  platformName: 'Windows 10',
  'cloud:options': {
     build: myTestBuild,
     name: myTestName,
  }
}
var browserOptions = new FirefoxOptions();
browserOptions.PlatformName = "Windows 10";
browserOptions.BrowserVersion = "92";

Utilitário para encontrar elemento (s) no Java

O utilitário para localizar elementos no Java (interfaces FindsBy) foram removidos visto que se destinavam apenas a uso interno. Os exemplos de código a seguir explicam isso melhor.

Encontrando um único elemento com findElement*

Antes

driver.findElementByClassName("className");
driver.findElementByCssSelector(".className");
driver.findElementById("elementId");
driver.findElementByLinkText("linkText");
driver.findElementByName("elementName");
driver.findElementByPartialLinkText("partialText");
driver.findElementByTagName("elementTagName");
driver.findElementByXPath("xPath");

Depois

driver.findElement(By.className("className"));
driver.findElement(By.cssSelector(".className"));
driver.findElement(By.id("elementId"));
driver.findElement(By.linkText("linkText"));
driver.findElement(By.name("elementName"));
driver.findElement(By.partialLinkText("partialText"));
driver.findElement(By.tagName("elementTagName"));
driver.findElement(By.xpath("xPath"));

Encontrando multiplos elementos com findElements*

Antes

driver.findElementsByClassName("className");
driver.findElementsByCssSelector(".className");
driver.findElementsById("elementId");
driver.findElementsByLinkText("linkText");
driver.findElementsByName("elementName");
driver.findElementsByPartialLinkText("partialText");
driver.findElementsByTagName("elementTagName");
driver.findElementsByXPath("xPath");

Depois

driver.findElements(By.className("className"));
driver.findElements(By.cssSelector(".className"));
driver.findElements(By.id("elementId"));
driver.findElements(By.linkText("linkText"));
driver.findElements(By.name("elementName"));
driver.findElements(By.partialLinkText("partialText"));
driver.findElements(By.tagName("elementTagName"));
driver.findElements(By.xpath("xPath"));

Atualizando as dependências

Verifique as subseções abaixo para isntalar o Selenium 4 e atualizar as dependências do seu projeto

Java

O processo de atualização do Selenium depende de qual ferramenta de compilação está sendo usada. Vamos mostrar as mais comuns para Java, como Maven e Gradle. A versão minínma do Java ainda é 8.

Maven

Antes

<dependencies>
  <!-- more dependencies ... -->
  <dependency>
    <groupId>org.seleniumhq.selenium</groupId>
    <artifactId>selenium-java</artifactId>
    <version>3.141.59</version>
  </dependency>
  <!-- more dependencies ... -->
</dependencies>

Depois

<dependencies>
    <!-- more dependencies ... -->
    <dependency>
        <groupId>org.seleniumhq.selenium</groupId>
        <artifactId>selenium-java</artifactId>
        <version>4.4.0</version>
    </dependency>
    <!-- more dependencies ... -->
</dependencies>

Após realizar a mudança, você pode executar mvn clean compile no mesmo diretório, onde o arquivo pom.xml está.

Gradle

Antes

plugins {
    id 'java'
}
group 'org.example'
version '1.0-SNAPSHOT'
repositories {
    mavenCentral()
}
dependencies {
    testImplementation 'org.junit.jupiter:junit-jupiter-api:5.7.0'
    testRuntimeOnly 'org.junit.jupiter:junit-jupiter-engine:5.7.0'
    implementation group: 'org.seleniumhq.selenium', name: 'selenium-java', version: '3.141.59'
}
test {
    useJUnitPlatform()
}

Depois

plugins {
    id 'java'
}
group 'org.example'
version '1.0-SNAPSHOT'
repositories {
    mavenCentral()
}
dependencies {
    testImplementation 'org.junit.jupiter:junit-jupiter-api:5.7.0'
    testRuntimeOnly 'org.junit.jupiter:junit-jupiter-engine:5.7.0'
    implementation group: 'org.seleniumhq.selenium', name: 'selenium-java', version: '4.4.0'
}
test {
    useJUnitPlatform()
}

Após realizar a mudança, você pode executar ./gradlew clean build no mesmo diretório onde o arquivo build.gradleestá.

Para verifica todas as versões do Java, você pode ir até MVNRepository.

C#

O local para obter atualizações para Selenium 4 em C# é NuGet Dentro do pacaote Selenium.WebDriver você pode seguir as instruções para atualizar para ultima versão. Dentro do Visual Studio, através do NuGet Package Manager você pode executar:

PM> Install-Package Selenium.WebDriver -Version 4.4.0

Python

A mudança mais importante para usar o Python é a versão minima requerida. Para Selenium 4 a versão miníma requerida será Python3.7 ou superior. Mais detalhes podem ser encontrados aqui:Python Package Index. Para atualizar através da linha de comando, você pode executar:

pip install selenium==4.4.3

Ruby

Detalhes para atualizar para o Selenium 4 podem ser vistos aqui: selenium-webdriver gem in RubyGems Para instalar a ultima versão, você pode executar:

gem install selenium-webdriver

Para adicioná-lo ao seu Gemfile:

gem 'selenium-webdriver', '~> 4.4.0'

JavaScript

O pacote selenium-webdriver pode ser encontrado pelo Node package manager, npmjs. Selenium 4 pode ser encontrado aqui. Para instalar, você pode executar:

npm install selenium-webdriver

Ou, atualize o seu package.json e execute npm install:

{
  "name": "selenium-tests",
  "version": "1.0.0",
  "dependencies": {
    "selenium-webdriver": "^4.4.0"
  }
}

Possíveis erros e mensagens de descontinuação

Aqui temos um conjunto de exemplos de código que o ajudarão a superar as mensagens de descontinuação, que você pode encontrar após atualizar para o Selenium 4.

Java

Waits e Timeout

Os parametros que eram esperados de ser recebidos em um Timeout trocaram de (long time, TimeUnit unit) para o (Duration duration).

Antes

driver.manage().timeouts().implicitlyWait(10, TimeUnit.SECONDS);
driver.manage().timeouts().setScriptTimeout(2, TimeUnit.MINUTES);
driver.manage().timeouts().pageLoadTimeout(10, TimeUnit.SECONDS);

Depois

driver.manage().timeouts().implicitlyWait(Duration.ofSeconds(10));
driver.manage().timeouts().scriptTimeout(Duration.ofMinutes(2));
driver.manage().timeouts().pageLoadTimeout(Duration.ofSeconds(10));

As esperas(waits) também esperam parâmetros diferentes agora. O WebDriverWait agora espera uma Duration em vez de um tempo limite long em segundos e milissegundos. Os métodos utilitários withTimeout e pollingEvery do FluentWait passaram do (long time, TimeUnit unit) para o (Duration duration).

Antes

new WebDriverWait(driver, 3)
.until(ExpectedConditions.elementToBeClickable(By.cssSelector("#id")));

Wait<WebDriver> wait = new FluentWait<WebDriver>(driver)
  .withTimeout(30, TimeUnit.SECONDS)
  .pollingEvery(5, TimeUnit.SECONDS)
  .ignoring(NoSuchElementException.class);

Depois

new WebDriverWait(driver, Duration.ofSeconds(3))
  .until(ExpectedConditions.elementToBeClickable(By.cssSelector("#id")));

  Wait<WebDriver> wait = new FluentWait<WebDriver>(driver)
  .withTimeout(Duration.ofSeconds(30))
  .pollingEvery(Duration.ofSeconds(5))
  .ignoring(NoSuchElementException.class);

A fusão de recursos não estã mais alterando o objeto de invocação

Antes era possível fundir um conjunto diferente de recursos em outro counjunto, e isso alterava o objeto de chamada. Agora, o resultado da operação de fusão precisa ser atribuído.

Antes

MutableCapabilities capabilities = new MutableCapabilities();
capabilities.setCapability("platformVersion", "Windows 10");
FirefoxOptions options = new FirefoxOptions();
options.setHeadless(true);
options.merge(capabilities);

Como resultado, o objeto options estava sendo modificado.

Depois

MutableCapabilities capabilities = new MutableCapabilities();
capabilities.setCapability("platformVersion", "Windows 10");
FirefoxOptions options = new FirefoxOptions();
options.setHeadless(true);
options = options.merge(capabilities);

O resultado da chamada merge precisa ser atribuído a um objeto.

Firefox Legacy

Antes do GeckoDriver existir, o projeto Selenium tinha uma implementação de driver para automatizar o Firefox(versão<48). Entretanto, esta implementação não é mais necessária, pois não funciona nas versões mais recentes do Firefox. Para evitar graves problemas ao atualizar para o Selenium 4, a opção setLegacy será mostrada como obsoleta. A recomendação é parar de utilizar a implementação antiga e depender apenas do GeckoDriver. O código a seguir mostrará a linha setLegacy obsoleta após atualizar.

FirefoxOptions options = new FirefoxOptions();
options.setLegacy(true);

BrowserType

A interface BrowserType existe há um bom tempo, más ela está ficando obsoleta a favor da nova interface Browser.

Antes

MutableCapabilities capabilities = new MutableCapabilities();
capabilities.setCapability("browserVersion", "92");
capabilities.setCapability("browserName", BrowserType.FIREFOX);

Depois

MutableCapabilities capabilities = new MutableCapabilities();
capabilities.setCapability("browserVersion", "92");
capabilities.setCapability("browserName", Browser.FIREFOX);

C#

AddAdditionalCapability está descontinuada

Em vez dela, AddAdditionalOption é recomendada. Aqui está um exemplo mostrando isso:

Antes

var browserOptions = new ChromeOptions();
browserOptions.PlatformName = "Windows 10";
browserOptions.BrowserVersion = "latest";
var cloudOptions = new Dictionary<string, object>();
browserOptions.AddAdditionalCapability("cloud:options", cloudOptions, true);

Depois

var browserOptions = new ChromeOptions();
browserOptions.PlatformName = "Windows 10";
browserOptions.BrowserVersion = "latest";
var cloudOptions = new Dictionary<string, object>();
browserOptions.AddAdditionalOption("cloud:options", cloudOptions);

Python

executable_path foi descontinuada, por favor, passe um Service object

No Selenium 4, você precisara definir o executable_path a partir de um objeto Service para evitar avisos de depreciação. (Ou não defina o caminho e, em vez disso, certifique-se de que o driver que você precisa esteja no System PATH.)

Antes

from selenium import webdriver
options = webdriver.ChromeOptions()
options.add_experimental_option("excludeSwitches", ["enable-automation"])
options.add_experimental_option("useAutomationExtension", False)
driver = webdriver.Chrome(executable_path=CHROMEDRIVER_PATH, options=options)

Depois

from selenium import webdriver
from selenium.webdriver.chrome.service import Service as ChromeService
options = webdriver.ChromeOptions()
options.add_experimental_option("excludeSwitches", ["enable-automation"])
options.add_experimental_option("useAutomationExtension", False)
service = ChromeService(executable_path=CHROMEDRIVER_PATH)
driver = webdriver.Chrome(service=service, options=options)

Resumo

Passamos pelas principais mudanças a serem levadas em consideração ao atualizar para o Selenium 4. Cobrimos os diferentes aspectos a serem cobertos quando o código de teste é preparado para a atualização, incluindo sugestões sobre como evitar possíveis problemas que podem aparecer ao usar a nova versão do Selenium. Para finalizar, também abordamos um conjunto de possíveis problemas com os quais você pode se deparar depois da atualização e compartilhamos possíveis correções para esses problemas.

2 - Driver Sessions

Starting and stopping a session is for opening and closing a browser.

Creating Sessions

Creating a new session corresponds with the W3C command for New session

The session is created automatically by initializing a new Driver class object.

Each language allows a session to be created with arguments from one of these classes (or equivalent):

  • Options to describe the kind of session you want; default values are used for local, but this is required for remote
  • Some form of CommandExecutor (the implementation varies between languages)
  • Listeners

Local Driver

The primary unique argument for starting a local driver includes information about starting the required driver service on the local machine.

  • Service object applies only to local drivers and provides information about the browser driver

Remote Driver

The primary unique argument for starting a remote driver includes information about where to execute the code. Read the details in the Remote Driver Section

Quitting Sessions

Quitting a session corresponds to W3C command for Deleting a Session.

Important note: the quit method is different from the close method, and it is recommended to always use quit to end the session

2.1 - Browser Options

These capabilities are shared by all browsers.

Page being translated from English to Portuguese. Do you speak Portuguese? Help us to translate it by sending us pull requests!

In Selenium 3, capabilities were defined in a session by using Desired Capabilities classes. As of Selenium 4, you must use the browser options classes. For remote driver sessions, a browser options instance is required as it determines which browser will be used.

These options are described in the w3c specification for Capabilities.

Each browser has custom options that may be defined in addition to the ones defined in the specification.

browserName

This capability is used to set the browserName for a given session. If the specified browser is not installed at the remote end, the session creation will fail.

browserVersion

This capability is optional, this is used to set the available browser version at remote end. For Example, if ask for Chrome version 75 on a system that only has 80 installed, the session creation will fail.

pageLoadStrategy

Three types of page load strategies are available.

The page load strategy queries the document.readyState as described in the table below:

Strategy Ready State Notes
normal complete Used by default, waits for all resources to download
eager interactive DOM access is ready, but other resources like images may still be loading
none Any Does not block WebDriver at all

The document.readyState property of a document describes the loading state of the current document.

When navigating to a new page via URL, by default, WebDriver will hold off on completing a navigation method (e.g., driver.navigate().get()) until the document ready state is complete. This does not necessarily mean that the page has finished loading, especially for sites like Single Page Applications that use JavaScript to dynamically load content after the Ready State returns complete. Note also that this behavior does not apply to navigation that is a result of clicking an element or submitting a form.

If a page takes a long time to load as a result of downloading assets (e.g., images, css, js) that aren’t important to the automation, you can change from the default parameter of normal to eager or none to speed up the session. This value applies to the entire session, so make sure that your waiting strategy is sufficient to minimize flakiness.

normal (default)

WebDriver waits until the load event fire is returned.

  val driver = ChromeDriver(chromeOptions)
  try {
    driver.get("https://www.google.com")
  }
  finally {
    driver.quit()
  }
}

platformName

This identifies the operating system at the remote-end, fetching the platformName returns the OS name.

In cloud-based providers, setting platformName sets the OS at the remote-end.

acceptInsecureCerts

This capability checks whether an expired (or) invalid TLS Certificate is used while navigating during a session.

If the capability is set to false, an insecure certificate error will be returned as navigation encounters any domain certificate problems. If set to true, invalid certificate will be trusted by the browser.

All self-signed certificates will be trusted by this capability by default. Once set, acceptInsecureCerts capability will have an effect for the entire session.

timeouts

A WebDriver session is imposed with a certain session timeout interval, during which the user can control the behaviour of executing scripts or retrieving information from the browser.

Each session timeout is configured with combination of different timeouts as described below:

Script Timeout

Specifies when to interrupt an executing script in a current browsing context. The default timeout 30,000 is imposed when a new session is created by WebDriver.

Page Load Timeout

Specifies the time interval in which web page needs to be loaded in a current browsing context. The default timeout 300,000 is imposed when a new session is created by WebDriver. If page load limits a given/default time frame, the script will be stopped by TimeoutException.

Implicit Wait Timeout

This specifies the time to wait for the implicit element location strategy when locating elements. The default timeout 0 is imposed when a new session is created by WebDriver.

unhandledPromptBehavior

Specifies the state of current session’s user prompt handler. Defaults to dismiss and notify state

User Prompt Handler

This defines what action must take when a user prompt encounters at the remote-end. This is defined by unhandledPromptBehavior capability and has the following states:

  • dismiss
  • accept
  • dismiss and notify
  • accept and notify
  • ignore

setWindowRect

Indicates whether the remote end supports all of the resizing and repositioning commands.

strictFileInteractability

This new capability indicates if strict interactability checks should be applied to input type=file elements. As strict interactability checks are off by default, there is a change in behaviour when using Element Send Keys with hidden file upload controls.

proxy

A proxy server acts as an intermediary for requests between a client and a server. In simple, the traffic flows through the proxy server on its way to the address you requested and back.

A proxy server for automation scripts with Selenium could be helpful for:

  • Capture network traffic
  • Mock backend calls made by the website
  • Access the required website under complex network topologies or strict corporate restrictions/policies.

If you are in a corporate environment, and a browser fails to connect to a URL, this is most likely because the environment needs a proxy to be accessed.

Selenium WebDriver provides a way to proxy settings:

import org.openqa.selenium.Proxy;
import org.openqa.selenium.WebDriver;
import org.openqa.selenium.chrome.ChromeDriver;
import org.openqa.selenium.chrome.ChromeOptions;

public class proxyTest {
public static void main(String[] args) {
Proxy proxy = new Proxy();
proxy.setHttpProxy("<HOST:PORT>");
ChromeOptions options = new ChromeOptions();
options.setCapability("proxy", proxy);
WebDriver driver = new ChromeDriver(options);
driver.get("https://www.google.com/");
driver.manage().window().maximize();
driver.quit();
}
}
from selenium import webdriver

PROXY = "<HOST:PORT>"
webdriver.DesiredCapabilities.FIREFOX['proxy'] = {
"httpProxy": PROXY,
"ftpProxy": PROXY,
"sslProxy": PROXY,
"proxyType": "MANUAL",

}

with webdriver.Firefox() as driver:
driver.get("https://selenium.dev")
using OpenQA.Selenium;
using OpenQA.Selenium.Chrome;

public class ProxyTest{
public static void Main() {
ChromeOptions options = new ChromeOptions();
Proxy proxy = new Proxy();
proxy.Kind = ProxyKind.Manual;
proxy.IsAutoDetect = false;
proxy.SslProxy = "<HOST:PORT>";
options.Proxy = proxy;
options.AddArgument("ignore-certificate-errors");
IWebDriver driver = new ChromeDriver(options);
driver.Navigate().GoToUrl("https://www.selenium.dev/");
}
}
proxy = Selenium::WebDriver::Proxy.new(http: '<HOST:PORT>')
cap   = Selenium::WebDriver::Remote::Capabilities.chrome(proxy: proxy)

driver = Selenium::WebDriver.for(:chrome, capabilities: cap)
driver.get('http://google.com')
let webdriver = require('selenium-webdriver');
let chrome = require('selenium-webdriver/chrome');
let proxy = require('selenium-webdriver/proxy');
let opts = new chrome.Options();

(async function example() {
opts.setProxy(proxy.manual({http: '<HOST:PORT>'}));
let driver = new webdriver.Builder()
.forBrowser('chrome')
.setChromeOptions(opts)
.build();
try {
await driver.get("https://selenium.dev");
}
finally {
await driver.quit();
}
}());
import org.openqa.selenium.Proxy
import org.openqa.selenium.WebDriver
import org.openqa.selenium.chrome.ChromeDriver
import org.openqa.selenium.chrome.ChromeOptions

class proxyTest {
fun main() {

        val proxy = Proxy()
        proxy.setHttpProxy("<HOST:PORT>")
        val options = ChromeOptions()
        options.setCapability("proxy", proxy)
        val driver: WebDriver = ChromeDriver(options)

2.2 - Command executors

These allow you to set various parameters for the HTTP library

2.3 - Command Listeners

These allow you to execute custom actions in every time specific Selenium commands are sent

2.4 - Browser Service

The Service classes are for managing the starting and stopping of drivers. They are not applicable in Remote Drivers.

  • Location of the driver
  • port to use
  • command line arguments to use

2.5 - Remote WebDriver

Page being translated from English to Portuguese. Do you speak Portuguese? Help us to translate it by sending us pull requests!

Você pode usar o WebDriver remotamente da mesma forma que o usaria localmente. A principal diferença é que um WebDriver remoto precisa ser configurado para que possa executar seus testes em uma máquina separada.

Um WebDriver remoto é composto por duas peças: um cliente e um servidor. O cliente é o seu teste WebDriver e o servidor é simplesmente um Servlet Java, que pode ser hospedado em qualquer servidor de aplicativo JEE moderno.

Para executar um cliente WebDriver remoto, primeiro precisamos nos conectar ao RemoteWebDriver. Fazemos isso apontando a URL para o endereço do servidor que está executando nossos testes. Para personalizar nossa configuração, definimos os recursos desejados. Abaixo está um exemplo de como instanciar um objeto WebDriver remoto apontando para nosso servidor remoto da web, www.example.com, executando nossos testes no Firefox.

FirefoxOptions firefoxOptions = new FirefoxOptions();
WebDriver driver = new RemoteWebDriver(new URL("http://www.example.com"), firefoxOptions);
driver.get("http://www.google.com");
driver.quit();
  
from selenium import webdriver

firefox_options = webdriver.FirefoxOptions()
driver = webdriver.Remote(
    command_executor='http://www.example.com',
    options=firefox_options
)
driver.get("http://www.google.com")
driver.quit() 
  
 FirefoxOptions firefoxOptions = new FirefoxOptions();
 IWebDriver driver = new RemoteWebDriver(new Uri("http://www.example.com"), firefoxOptions);
 driver.Navigate().GoToUrl("http://www.google.com");
 driver.Quit();
  
require 'selenium-webdriver'

driver = Selenium::WebDriver.for :remote, url: "http://www.example.com", desired_capabilities: :firefox
driver.get "http://www.google.com"
driver.close
  
const { Builder, Capabilities } = require("selenium-webdriver");
var capabilities = Capabilities.firefox();
(async function helloSelenium() {
    let driver = new Builder()
        .usingServer("http://example.com")   
        .withCapabilities(capabilities)
        .build();
    try {

})();  
  
firefoxOptions = FirefoxOptions()
driver: WebDriver = new RemoteWebDriver(new URL("http://www.example.com"), firefoxOptions)
driver.get("http://www.google.com")
driver.quit()
  

Para personalizar ainda mais nossa configuração de teste, podemos adicionar outros recursos desejados.

Opções do browser

Por exemplo, suponha que você queira executar o Chrome no Windows XP, usando o Chrome versão 67:

ChromeOptions chromeOptions = new ChromeOptions();
chromeOptions.setCapability("browserVersion", "67");
chromeOptions.setCapability("platformName", "Windows XP");
WebDriver driver = new RemoteWebDriver(new URL("http://www.example.com"), chromeOptions);
driver.get("http://www.google.com");
driver.quit();
  
from selenium import webdriver

chrome_options = webdriver.ChromeOptions()
chrome_options.set_capability("browserVersion", "67")
chrome_options.set_capability("platformName", "Windows XP")
driver = webdriver.Remote(
    command_executor='http://www.example.com',
    options=chrome_options
)
driver.get("http://www.google.com")
driver.quit()  
  
var chromeOptions = new ChromeOptions();
chromeOptions.BrowserVersion = "67";
chromeOptions.PlatformName = "Windows XP";
IWebDriver driver = new RemoteWebDriver(new Uri("http://www.example.com"), chromeOptions);
driver.Navigate().GoToUrl("http://www.google.com");
driver.Quit();
  
caps = Selenium::WebDriver::Remote::Capabilities.chrome
caps.platform = Windows XP
caps.version = 67

driver = Selenium::WebDriver.for :remote, :url => "http://www.example.com", :desired_capabilities => caps
  
const { Builder } = require("selenium-webdriver");
const chrome = require("selenium-webdriver/chrome");
let opts = new chrome.Options();
opts.setAcceptInsecureCerts(true);
opts.setBrowserVersion('67');
opts.setPlatform('Windows XP');
(async function helloSelenium() {
    let driver = new Builder()
        .usingServer("http://example.com")
        .forBrowser('chrome')
        .setChromeOptions(opts)
        .build();
    try {
        await driver.get('http://www.google.com');
    }
    finally {
        await driver.quit();
    }
})();
  
val chromeOptions = ChromeOptions()
chromeOptions.setCapability("browserVersion", "67")
chromeOptions.setCapability("platformName", "Windows XP")
val driver: WebDriver = new RemoteWebDriver(new URL("http://www.example.com"), chromeOptions)
driver.get("http://www.google.com")
driver.quit()
  

Detector de arquivo local

O Detector de Arquivo Local permite a transferência de arquivos da máquina do cliente para o servidor remoto. Por exemplo, se um teste precisa carregar um arquivo para um aplicativo da web, um WebDriver remoto pode transferir automaticamente o arquivo da máquina local para o servidor web remoto durante o tempo de execução. Isso permite que o arquivo seja carregado da máquina remota executando o teste. Não é habilitado por padrão e pode ser habilitado em da seguinte forma:

driver.setFileDetector(new LocalFileDetector());
  
from selenium.webdriver.remote.file_detector import LocalFileDetector

driver.file_detector = LocalFileDetector()
  
var allowsDetection = this.driver as IAllowsFileDetection;
if (allowsDetection != null)
{
   allowsDetection.FileDetector = new LocalFileDetector();
}
  
@driver.file_detector = lambda do |args|
  # args => ["/path/to/file"]
  str = args.first.to_s
  str if File.exist?(str)
end
  
var remote = require('selenium-webdriver/remote');
driver.setFileDetector(new remote.FileDetector);  
  
driver.fileDetector = LocalFileDetector()
  

Assim que o código acima for definido, você pode fazer upload de um arquivo em seu teste da seguinte maneira:

driver.get("http://sso.dev.saucelabs.com/test/guinea-file-upload");
WebElement upload = driver.findElement(By.id("myfile"));
upload.sendKeys("/Users/sso/the/local/path/to/darkbulb.jpg");
  
driver.get("http://sso.dev.saucelabs.com/test/guinea-file-upload")

driver.find_element(By.ID, "myfile").send_keys("/Users/sso/the/local/path/to/darkbulb.jpg")
  
driver.Navigate().GoToUrl("http://sso.dev.saucelabs.com/test/guinea-file-upload");
IWebElement upload = driver.FindElement(By.Id("myfile"));
upload.SendKeys(@"/Users/sso/the/local/path/to/darkbulb.jpg");
  
@driver.navigate.to "http://sso.dev.saucelabs.com/test/guinea-file-upload"
    element = @driver.find_element(:id, 'myfile')
    element.send_keys "/Users/sso/SauceLabs/sauce/hostess/maitred/maitred/public/images/darkbulb.jpg"
  
driver.get("http://sso.dev.saucelabs.com/test/guinea-file-upload");
var upload = driver.findElement(By.id("myfile"));
upload.sendKeys("/Users/sso/the/local/path/to/darkbulb.jpg");  
  
driver.get("http://sso.dev.saucelabs.com/test/guinea-file-upload")
val upload: WebElement = driver.findElement(By.id("myfile"))
upload.sendKeys("/Users/sso/the/local/path/to/darkbulb.jpg")
  

Tracing client requests

This feature is only available for Java client binding (Beta onwards). The Remote WebDriver client sends requests to the Selenium Grid server, which passes them to the WebDriver. Tracing should be enabled at the server and client-side to trace the HTTP requests end-to-end. Both ends should have a trace exporter setup pointing to the visualization framework. By default, tracing is enabled for both client and server. To set up the visualization framework Jaeger UI and Selenium Grid 4, please refer to Tracing Setup for the desired version.

For client-side setup, follow the steps below.

Add the required dependencies

Installation of external libraries for tracing exporter can be done using Maven. Add the opentelemetry-exporter-jaeger and grpc-netty dependency in your project pom.xml:

  <dependency>
      <groupId>io.opentelemetry</groupId>
      <artifactId>opentelemetry-exporter-jaeger</artifactId>
      <version>1.0.0</version>
    </dependency>
    <dependency>
      <groupId>io.grpc</groupId>
      <artifactId>grpc-netty</artifactId>
      <version>1.35.0</version>
    </dependency>

Add/pass the required system properties while running the client

System.setProperty("otel.traces.exporter", "jaeger");
System.setProperty("otel.exporter.jaeger.endpoint", "http://localhost:14250");
System.setProperty("otel.resource.attributes", "service.name=selenium-java-client");

ImmutableCapabilities capabilities = new ImmutableCapabilities("browserName", "chrome");

WebDriver driver = new RemoteWebDriver(new URL("http://www.example.com"), capabilities);

driver.get("http://www.google.com");

driver.quit();

Please refer to Tracing Setup for more information on external dependencies versions required for the desired Selenium version.

Browser specific functionalities

Some browser specific functionalities require workarounds as mentioned in this issue.

3 - Navegadores suportados

Cada navegador tem capacidades e características únicas.

3.1 - Funcionalidade específica do Chrome

Estas capacidades e características são específicas ao navegador Google Chrome.

Por omissão, Selenium 4 é compatível com Chrome v75 e superiores. Note que a versão (maior) do navegador e do chromedriver devem ser idênticas.

Opções

Capacidades comuns a todos os navegadores estão descritas na página Opções.

Capacidades únicas ao Chrome podem ser encontradas na página da Google para Capacidades e & ChromeOptions

Este é um exemplo de como iniciar uma sessão Chrome com um conjunto de opções básicas:

        ChromeOptions options = new ChromeOptions();
        driver = new ChromeDriver(options);
    options = ChromeOptions()
    driver = webdriver.Chrome(options=options)
      var options = new ChromeOptions();
      var driver = new ChromeDriver(options);
    options = Selenium::WebDriver::Options.chrome
    @driver = Selenium::WebDriver.for :chrome, options: options
      const Options = new Chrome.Options();
      let driver = await env
        .builder()
        .setChromeOptions(Options)
        .build();

Alguns exemplos de uso com capacidades diferentes:

Argumentos

O parametro args é usado para indicar uma lista de opções ao iniciar o navegador. Opções mais frequentes incluem --start-maximized e --headless=new

Adicione uma opção:

        ChromeOptions options = new ChromeOptions();
        options.addArguments("--headless=new");
        driver = new ChromeDriver(options);
    chrome_options = ChromeOptions()
    chrome_options.add_argument("--headless=new")
      var options = new ChromeOptions();
      options.AddArgument("--headless=new");
      var driver = new ChromeDriver(options);
    options = Selenium::WebDriver::Options.chrome(args: ['--headless=new'])
      let driver = await env
        .builder()
        .setChromeOptions(options.addArguments('--headless=new'))
        .build();

Iniciar navegador numa localização específica

Adicionar uma localização:

      let driver = await env
        .builder()
        .setChromeOptions(options.setChromeBinaryPath(`Path to chrome binary`))
        .build();

Adicionar extensões

O parametro extensions aceita ficheiros crx

The extensions parameter accepts crx files. As for unpacked directories, please use the load-extension argument instead, as mentioned in this post.

Adicionar uma extensão:

Manter o navegador aberto

Ao definir o parametro detach para true, irá manter o navegador aberto mesmo depois do driver fechar.

Adicionar detach:

        ChromeOptions options = new ChromeOptions();
        options.setExperimentalOption("detach", true);
        driver = new ChromeDriver(options);
    chrome_options = ChromeOptions()
    chrome_options.add_experimental_option("detach", True)
    options = Selenium::WebDriver::Options.chrome(detach: true)
      let driver = await env
        .builder()
        .setChromeOptions(options.detachDriver(true))
        .build();

Excluindo parametros

Chrome adiciona vários parametros, se não os pretende adicionar, passe-os em excludeSwitches.

Um exemplo comum é voltar a activar o bloqueador de popups.

Exclua parametros:

    chrome_options = ChromeOptions()
    chrome_options.add_experimental_option('excludeSwitches', ['enable-automation'])
    options = Selenium::WebDriver::Options.chrome(exclude_switches: ['enable-automation'])
      let driver = await env
        .builder()
        .setChromeOptions(options.excludeSwitches('enable-automation'))
        .build();

Casting

Pode comandar dispositivos Chrome Cast, incluindo partilhar abas

Condições de rede

Pode simular vários estados de rede (como exemplo, simular situações com pouca banda).

The following examples are for local webdrivers. For remote webdrivers, please refer to the Remote WebDriver page.

3.2 - Funcionalidade específica do Edge

Estas capacidades e características são específicas ao navegador Microsoft Edge.

Microsoft Edge foi criado com recurso ao Chromium, cuja versão mais antiga suportada é a v79. Tal como o Chrome, a versão (maior) do edgedriver deve ser igual à do navegador Edge.

Todas as capacidades e opções encontradas na página Chrome page irão funcionar de igual forma para o Edge.

Opções

Este é um exemplo de como iniciar uma sessão Edge com um conjunto de opções básicas:

        EdgeOptions options = new EdgeOptions();
        driver = new EdgeDriver(options);
    options = EdgeOptions()
    driver = webdriver.Edge(options=options)
            var options = new EdgeOptions();
            var driver = new EdgeDriver(options);
    options = Selenium::WebDriver::Options.edge
    @driver = Selenium::WebDriver.for :edge, options: options
      let options = new edge.Options();
      driver = await env.builder()
        .setEdgeOptions(options)
        .setEdgeService(new edge.ServiceBuilder(edgedriver.binPath()))
        .build();

Argumentos

O parametro args é usado para indicar uma lista de opções ao iniciar o navegador. Opções mais frequentes incluem --start-maximized e --headless=new

        driver = new EdgeDriver(options);
    options = EdgeOptions()
    options.add_argument("--headless=new")
            var options = new EdgeOptions();
            options.AddArgument("--headless=new");
    options = Selenium::WebDriver::Options.edge(args: ['--headless=new'])
    @driver = Selenium::WebDriver.for :edge, options: options

Modo compatibilidade Internet Explorer

O Microsoft Edge pode ser controlado em modo “compatibilidade Internet Explorer”, são usadas classes do Internet Explorer Driver em conjunção com o Microsoft Edge. Leia a página Internet Explorer para mais detalhes.

3.3 - Funcionalidade específica do Firefox

Estas capacidades e características são específicas ao navegador Mozilla Firefox.

Por omissão, Selenium 4 é compatível com Firefox 78 ou superior. Recomendamos que use sempre a versão mais recente do geckodriver.

Opções

Capacidades comuns a todos os navegadores estão descritas na página Opções.

Capacidades únicas ao Firefox podem ser encontradas na página da Mozilla para firefoxOptions

Este é um exemplo de como iniciar uma sessão Firefox com um conjunto de opções básicas:

        FirefoxOptions options = new FirefoxOptions();
        driver = new FirefoxDriver(options);
    options = FirefoxOptions()
    driver = webdriver.Firefox(options=options)
            var options = new FirefoxOptions();
            driver = new FirefoxDriver(options);
    options = Selenium::WebDriver::Options.firefox
    @driver = Selenium::WebDriver.for :firefox, options: options
      let options = new firefox.Options();
      driver = await env.builder()
        .setFirefoxOptions(options)
        .build();

Alguns exemplos de uso com capacidades diferentes:

Argumentos

O parametro args é usado para indicar uma lista de opções ao iniciar o navegador. Opções mais frequentes incluem -headless e "-profile", "/path/to/profile"

Adicione uma opção:

        FirefoxOptions options = new FirefoxOptions();
        options.addArguments("-headless");
options=Options()
options.add_argument("-profile")
options.add_argument("/path/to/profile")
            var options = new FirefoxOptions();
            options.AddArgument("-headless");
            driver = new FirefoxDriver(options);
    let driver = new Builder()
      .setFirefoxOptions(options.addArguments('--headless'))
      .build();

Iniciar navegador numa localização específica

O parametro binary é usado contendo o caminho para uma localização específica do navegador. Como exemplo, pode usar este parametro para indicar ao geckodriver a versão Firefox Nightly ao invés da versão de produção, quando ambas versões estão presentes no seu computador.

Adicionar uma localização:

Perfis

Existem várias formas de trabalhar com perfis Firefox

FirefoxProfile profile = new FirefoxProfile();
FirefoxOptions options = new FirefoxOptions();
options.setProfile(profile);
driver = new RemoteWebDriver(options);
  
from selenium.webdriver.firefox.options import Options
from selenium.webdriver.firefox.firefox_profile import FirefoxProfile
options=Options()
firefox_profile = FirefoxProfile()
firefox_profile.set_preference("javascript.enabled", False)
options.profile = firefox_profile
  
var options = new FirefoxOptions();
var profile = new FirefoxProfile();
options.Profile = profile;
var driver = new RemoteWebDriver(options);
  
profile = Selenium::WebDriver::Firefox::Profile.new
profile['browser.download.dir'] = "/tmp/webdriver-downloads"
options = Selenium::WebDriver::Firefox::Options.new(profile: profile)
driver = Selenium::WebDriver.for :firefox, options: options
  
const { Builder } = require("selenium-webdriver");
const firefox = require('selenium-webdriver/firefox');

const options = new firefox.Options();
let profile = '/path to custom profile';
options.setProfile(profile);
const driver = new Builder()
    .forBrowser('firefox')
    .setFirefoxOptions(options)
    .build();
  
val options = FirefoxOptions()
options.profile = FirefoxProfile()
driver = RemoteWebDriver(options)
  

Extras

Ao invés do Chrome, os extras do Firefos não são adicionados como parte das capacidades, mas sim após iniciar o driver.

Unlike Chrome, Firefox extensions are not added as part of capabilities as mentioned in this issue, they are created after starting the driver.

The following examples are for local webdrivers. For remote webdrivers, please refer to the Remote WebDriver page.

Instalação

Um arquivo xpi que pode ser obtido da página Mozilla Extras

        Path xpiPath = Paths.get("src/test/resources/extensions/selenium-example.xpi");
        driver.installExtension(xpiPath);
    path = os.path.abspath("tests/extensions/webextensions-selenium-example.xpi")
    driver.install_addon(path)
            string baseDir = AppDomain.CurrentDomain.BaseDirectory;
            string extensionFilePath = Path.Combine(baseDir, "../../../Extensions/webextensions-selenium-example.xpi");
            driver.InstallAddOnFromFile(Path.GetFullPath(extensionFilePath));
    driver.install_addon(extension_file_path)

Desinstalação

Desinstalar uma extensão implica saber o seu id que pode ser obtido como valor de retorno durante a instalação.

        Path xpiPath = Paths.get("src/test/resources/extensions/selenium-example.xpi");
        String id = driver.installExtension(xpiPath);
        driver.uninstallExtension(id);
    path = os.path.abspath("tests/extensions/webextensions-selenium-example.xpi")
    id = driver.install_addon(path)
    driver.uninstall_addon(id)

Selenium v4.5

            string baseDir = AppDomain.CurrentDomain.BaseDirectory;
            string extensionFilePath = Path.Combine(baseDir, "../../../Extensions/webextensions-selenium-example.xpi");
            string extensionId = driver.InstallAddOnFromFile(Path.GetFullPath(extensionFilePath));
            driver.UninstallAddOn(extensionId);
    extension_id = driver.install_addon(extension_file_path)
    driver.uninstall_addon(extension_id)

Instalação de extensões não assinadas

Quando trabalhar em uma extensão não terminada ou não publicada, provavelmente ela não estará assinada. Desta forma, só pode ser instalada como “temporária”. Isto pode ser feito passando uma arquivo ZIP ou uma pasta, este é um exemplo com uma pasta:

        Path path = Paths.get("src/test/resources/extensions/selenium-example");
        driver.installExtension(path, true);
    path = os.path.abspath("tests/extensions/webextensions-selenium-example/")
    driver.install_addon(path, temporary=True)

Selenium v4.5

            string baseDir = AppDomain.CurrentDomain.BaseDirectory;
            string extensionDirPath = Path.Combine(baseDir, "../../../Extensions/webextensions-selenium-example/");
            driver.InstallAddOnFromDirectory(Path.GetFullPath(extensionDirPath), true);

Selenium v4.5

    driver.install_addon(extension_dir_path, true)

3.4 - Funcionalidade específica do IE

Estas capacidades e características são específicas ao navegador Microsoft Internet Explorer.

Desde Junho de 2022, o Projecto Selenium deixou de suportar oficialmente o navegador Internet Explorer. O driver Internet Explorer continua a suportar a execução do Microsoft Edge no modo “IE Compatibility Mode.”

Considerações especiais

O IE Driver é o único driver mantido directamente pelo Projecto Selenium. Embora existam binários para as versões de 32 e 64 bits, existem algumas limitações conhecidas com o driver de 64 bits. Desta forma, recomenda-se a utilização do driver de 32 bits.

Informação adicional sobre como usar o Internet Explorer pode ser encontrada na página IE Driver Server

Opções

Este é um exemplo de como iniciar o navegador Microsoft Edge em modo compatibilidade Internet Explorer usando um conjunto de opções básicas:

        InternetExplorerOptions options = new InternetExplorerOptions();
        driver = new InternetExplorerDriver(options);
    options = InternetExplorerOptions()
    driver = webdriver.Ie(options=options)
            var options = new InternetExplorerOptions();
            var driver = new InternetExplorerDriver(options);
    options = Selenium::WebDriver::Options.ie
    @driver = Selenium::WebDriver.for :ie, options: options
  let driver = await new Builder()
    .forBrowser('internet explorer')
    .setIEOptions(options)
    .build();
  val options = InternetExplorerOptions()
  val driver = InternetExplorerDriver(options)

A partir do driver versão v4.5.0:

  • Se o IE não estiver presente no sistema (ausente por omissão no Windows 11), não necessita usar os parametros “attachToEdgeChrome” e “withEdgeExecutablePath”, pois o IE Driver irá encontrar e usar o Edge automaticamente.
  • Se o IE e o Edge estiverem ambos presentes no sistema, use o parametro “attachToEdgeChrome”, o IE Driver irá encontrar e usar o Edge automaticamente.

As of Internet Explorer Driver v4.7.0:

  • No longer need to set Ignore Zoom Level for Edge in IE Mode

Aqui pode ver alguns exemplos de utilização com capacidades diferentes:

fileUploadDialogTimeout

Em alguns ambientes, o Internet Explorer pode expirar ao abrir a Caixa de Diálogo de upload de arquivo. O IEDriver tem um tempo limite padrão de 1000 ms, mas você pode aumentar o tempo limite usando o recurso fileUploadDialogTimeout.

InternetExplorerOptions options = new InternetExplorerOptions();
options.waitForUploadDialogUpTo(Duration.ofSeconds(2));
WebDriver driver = new RemoteWebDriver(options);
  
from selenium import webdriver

options = webdriver.IeOptions()
options.file_upload_dialog_timeout = 2000
driver = webdriver.Ie(options=options)

# Navegar para Url
driver.get("http://www.google.com")

driver.quit()
  
var options = new InternetExplorerOptions();
options.FileUploadDialogTimeout = TimeSpan.FromMilliseconds(2000);
var driver = new RemoteWebDriver(options);
  
options = Selenium::WebDriver::IE::Options.new
options.file_upload_dialog_timeout = 2000
driver = Selenium::WebDriver.for(:ie, options: options)
  
const ie = require('selenium-webdriver/ie');
let options = new ie.Options().fileUploadDialogTimeout(2000);
let driver = await Builder()
          .setIeOptions(options)
          .build(); 
  
val options = InternetExplorerOptions()
options.waitForUploadDialogUpTo(Duration.ofSeconds(2))
val driver = RemoteWebDriver(options)
  

ensureCleanSession

Quando definido como true, este recurso limpa o Cache, Histórico do navegador e cookies para todas as instâncias em execução do InternetExplorer, incluindo aquelas iniciadas manualmente ou pelo driver. Por padrão, é definido como false.

Usar este recurso causará queda de desempenho quando iniciar o navegador, pois o driver irá esperar até que o cache seja limpo antes de iniciar o navegador IE.

Esse recurso aceita um valor booleano como parâmetro.

InternetExplorerOptions options = new InternetExplorerOptions();
options.destructivelyEnsureCleanSession();
WebDriver driver = new RemoteWebDriver(options);
  
from selenium import webdriver

options = webdriver.IeOptions()
options.ensure_clean_session = True
driver = webdriver.Ie(options=options)

# Navegar para Url
driver.get("http://www.google.com")

driver.quit()
  
var options = new InternetExplorerOptions();
options.EnsureCleanSession = true;
var driver = new RemoteWebDriver(options);
  
options = Selenium::WebDriver::IE::Options.new
options.ensure_clean_session = true
driver = Selenium::WebDriver.for(:ie, options: options)
  
const ie = require('selenium-webdriver/ie');
let options = new ie.Options().ensureCleanSession(true);
let driver = await Builder()
          .setIeOptions(options)
          .build(); 
  
val options = InternetExplorerOptions()
options.destructivelyEnsureCleanSession()
val driver = RemoteWebDriver(options)
  

ignoreZoomSetting

O driver do InternetExplorer espera que o nível de zoom do navegador seja de 100%, caso contrário, o driver lançará uma exceção. Este comportamento padrão pode ser desativado definindo ignoreZoomSetting como true.

Esse recurso aceita um valor booleano como parâmetro.

InternetExplorerOptions options = new InternetExplorerOptions();
options.ignoreZoomSettings();
WebDriver driver = new RemoteWebDriver(options);
  
from selenium import webdriver

options = webdriver.IeOptions()
options.ignore_zoom_level = True
driver = webdriver.Ie(options=options)

# Navegar para Url
driver.get("http://www.google.com")

driver.quit()
  
var options = new InternetExplorerOptions();
options.IgnoreZoomLevel = true;
var driver = new RemoteWebDriver(options);
  
options = Selenium::WebDriver::IE::Options.new
options.ignore_zoom_level = true
driver = Selenium::WebDriver.for(:ie, options: options)
  
const ie = require('selenium-webdriver/ie');
let options = new ie.Options().ignoreZoomSetting(true);
let driver = await Builder()
          .setIeOptions(options)
          .build(); 
  
val options = InternetExplorerOptions()
options.ignoreZoomSettings()
val driver = RemoteWebDriver(options)
  

ignoreProtectedModeSettings

Se deve ignorar a verificação do Modo protegido durante o lançamento uma nova sessão do IE.

Se não for definido e as configurações do Modo protegido não forem iguais para todas as zonas, uma exceção será lançada pelo driver.

Se a capacidade for definida como true, os testes podem tornar-se instáveis, não responderem ou os navegadores podem travar. No entanto, esta ainda é de longe a segunda melhor escolha, e a primeira escolha sempre deve ser definir as configurações do Modo protegido de cada zona manualmente. Se um usuário estiver usando esta propriedade, apenas um “melhor esforço” no suporte será dado.

Esse recurso aceita um valor booleano como parâmetro.

InternetExplorerOptions options = new InternetExplorerOptions();
options.introduceFlakinessByIgnoringSecurityDomains();
WebDriver driver = new RemoteWebDriver(options);
  
from selenium import webdriver

options = webdriver.IeOptions()
options.ignore_protected_mode_settings = True
driver = webdriver.Ie(options=options)

# Navegar para Url
driver.get("http://www.google.com")

driver.quit()
  
var options = new InternetExplorerOptions();
options.IntroduceInstabilityByIgnoringProtectedModeSettings = true;
var driver = new RemoteWebDriver(options);
  
options = Selenium::WebDriver::IE::Options.new
options.ignore_protected_mode_settings = true
driver = Selenium::WebDriver.for(:ie, options: options)
  
const ie = require('selenium-webdriver/ie');
let options = new ie.Options().introduceFlakinessByIgnoringProtectedModeSettings(true);
let driver = await Builder()
          .setIeOptions(options)
          .build(); 
  
val options = InternetExplorerOptions()
options.introduceFlakinessByIgnoringSecurityDomains()
val driver = RemoteWebDriver(options)
  

silent

Quando definido como true, esse recurso suprime a saída de diagnóstico do IEDriverServer.

Esse recurso aceita um valor booleano como parâmetro.

InternetExplorerOptions options = new InternetExplorerOptions();
options.setCapability("silent", true);
WebDriver driver = new InternetExplorerDriver(options);
  
from selenium import webdriver

Opções de linha de comando do IE

O Internet Explorer inclui várias opções de linha de comando que permitem solucionar problemas e configurar o navegador.

Os seguintes pontos descrevem algumas opções de linha de comando com suporte

  • -private: Usado para iniciar o IE no modo de navegação privada. Isso funciona para o IE 8 e versões posteriores.

  • -k: Inicia o Internet Explorer no modo quiosque. O navegador é aberto em uma janela maximizada que não exibe a barra de endereço, os botões de navegação ou a barra de status.

  • -extoff: Inicia o IE no modo sem add-on. Esta opção é usada especificamente para solucionar problemas com complementos do navegador. Funciona no IE 7 e versões posteriores.

Nota: forceCreateProcessApi deve ser habilitado para que os argumentos da linha de comando funcionem.

3.5 - Funcionalidade específica do Safari

Estas capacidades e características são específicas ao navegador Apple Safari.

Ao invés dos drivers para Chromium e Firefox, o safaridriver faz parte to sistema Operativo. Para activar a automação no Safari, execute o seguinte comando no terminal:

safaridriver --enable

Opções

Capacidades comuns a todos os navegadores estão descritas na página Opções.

Capacidades únicas ao Safari podem ser encontradas na página da Apple WebDriver para Safari

Este é um exemplo de como iniciar uma sessão Safari com um conjunto de opções básicas::

        SafariOptions options = new SafariOptions();
        driver = new SafariDriver(options);
    options = SafariOptions()
    driver = webdriver.Safari(options=options)
            var options = new SafariOptions();
            var driver = new SafariDriver(options);
    options = Selenium::WebDriver::Options.safari
    @driver = Selenium::WebDriver.for :safari, options: options
      let driver = await env.builder()
      .setSafariOptions(options)
      .build();
  val options = SafariOptions()
  val driver = SafariDriver(options)

Mobile (celular)

Se pretende automatizar Safari em iOS, deve olhar para o Projecto Appium.

4 - Esperas

Geralmente, pode-se dizer que o WebDriver tem uma API de blocante. Porque é uma biblioteca fora de processo que instrui ao navegador o que fazer, e porque a plataforma web tem uma natureza intrinsecamente assíncrona, O WebDriver não rastreia o estado ativo em tempo real do DOM. Isso traz alguns desafios que discutiremos aqui.

Por experiência, a maioria dos problemas intermitentes que surgem do uso de Selenium e WebDriver estão conectados a condições de corrida que ocorrem entre o navegador e as instruções do usuário. Um exemplo pode ser que o usuário instrui o navegador a navegar para uma página, em seguida, obtém um erro no such element ao tentar encontrar um elemento.

Considere o seguinte documento:

<!doctype html>
<meta charset=utf-8>
<title>Race Condition Example</title>

<script>
  var initialised = false;
  window.addEventListener("load", function() {
    var newElement = document.createElement("p");
    newElement.textContent = "Hello from JavaScript!";
    document.body.appendChild(newElement);
    initialised = true;
  });
</script>

As instruções do WebDriver podem parecer inocentes:

driver.get("file:///race_condition.html");
WebElement element = driver.findElement(By.tagName("p"));
assertEquals(element.getText(), "Hello from JavaScript!");
  
driver.navigate("file:///race_condition.html")
el = driver.find_element(By.TAG_NAME, "p")
assert el.text == "Hello from JavaScript!"
  
driver.Navigate().GoToUrl("file:///race_condition.html");
IWebElement element = driver.FindElement(By.TagName("p"));
assertEquals(element.Text, "Hello from JavaScript!");
  
require 'selenium-webdriver'
driver = Selenium::WebDriver.for :firefox
begin
  # Navigate to URL
  driver.get 'file:///race_condition.html'

  # Get and store Paragraph Text
  search_form = driver.find_element(:css,'p').text

  "Hello from JavaScript!".eql? search_form
ensure
  driver.quit
end
  
await driver.get('file:///race_condition.html');
const element = driver.findElement(By.css('p'));
assert.strictEqual(await element.getText(), 'Hello from JavaScript!');
  
driver.get("file:///race_condition.html")
val element = driver.findElement(By.tagName("p"))
assert(element.text == "Hello from JavaScript!")
  

O problema aqui é que a estratégia de carregamento de página padrão usado no WebDriver escuta o document.readyState para mudar para "complete" antes de retornar da chamada para navigate. Porque o elemento p é adicionado após o carregamento do documento concluído, este script WebDriver pode ser intermitente. “Pode” ser intermitente porque nenhuma garantia pode ser feita sobre elementos ou eventos que disparam de forma assíncrona sem esperar explicitamente - ou bloquear - nesses eventos.

Felizmente, o conjunto normal de instruções disponível na interface _WebElement _ - tal como WebElement.click e WebElement.sendKeys — são garantidamente síncrono, em que as chamadas de função não retornarão (ou o retorno de chamada não será acionado em linguagens de estilo de retorno de chamada) até que o comando seja concluído no navegador. As APIs avançadas de interação com o usuário, Keyboard e Mouse, são exceções, pois são explicitamente pretendidas como comandos assíncronos “faça o que eu digo”.

Esperar é fazer a execução de tarefa automatizada esperar passar um certo tempo antes de continuar com a próxima etapa.

Para superar o problema das condições de corrida entre o navegador e o script WebDriver, a maioria dos clientes Selenium vem com um pacote wait. Ao empregar uma espera, você está usando o que é comumente referido como uma espera explícita.

Espera explícita

Esperas explícitas estão disponíveis para clientes Selenium para linguagens procedurais imperativas. Eles permitem que seu código interrompa a execução do programa, ou congelar o tópico, até que a condição que você passe resolva. A condição é chamada com uma certa frequência até que o tempo limite de espera tenha decorrido. Isso significa que, enquanto a condição retornar um valor falso, ele continuará tentando e esperando.

Como as esperas explícitas permitem que você espere até que uma condição ocorra, eles são adequados para sincronizar o estado entre o navegador e seu DOM, e seu script WebDriver.

Para remediar o nosso conjunto de instruções com erros de antes, poderíamos empregar um tempo de espera para que a chamada findElement espere até que o elemento adicionado dinamicamente do script seja adicionado ao DOM:

WebDriver driver = new ChromeDriver();
driver.get("https://google.com/ncr");
driver.findElement(By.name("q")).sendKeys("cheese" + Keys.ENTER);
// Initialize and wait till element(link) became clickable - timeout in 10 seconds
WebElement firstResult = new WebDriverWait(driver, Duration.ofSeconds(10))
        .until(ExpectedConditions.elementToBeClickable(By.xpath("//a/h3")));
// Print the first result
System.out.println(firstResult.getText());
  
from selenium.webdriver.support.wait import WebDriverWait
def document_initialised(driver):
    return driver.execute_script("return initialised")

driver.navigate("file:///race_condition.html")
WebDriverWait(driver, timeout=10).until(document_initialised)
el = driver.find_element(By.TAG_NAME, "p")
assert el.text == "Hello from JavaScript!"
  
driver = new ChromeDriver();
driver.Url = "https://www.google.com/ncr";
driver.FindElement(By.Name("q")).SendKeys("cheese" + Keys.Enter);

WebDriverWait wait = new WebDriverWait(driver, TimeSpan.FromSeconds(10));
IWebElement firstResult = wait.Until(e => e.FindElement(By.XPath("//a/h3")));

Console.WriteLine(firstResult.Text);
  
require 'selenium-webdriver'
driver = Selenium::WebDriver.for :firefox
wait = Selenium::WebDriver::Wait.new(:timeout => 10)

def document_initialised(driver)
  driver.execute_script('return initialised')
end

begin
  driver.get 'file:///race_condition.html'
  wait.until{document_initialised driver}
  search_form = driver.find_element(:css,'p').text
  "Hello from JavaScript!".eql? search_form
ensure
  driver.quit
end
  
const documentInitialised = () =>
    driver.executeScript('return initialised');

await driver.get('file:///race_condition.html');
await driver.wait(() => documentInitialised(), 10000);
const element = driver.findElement(By.css('p'));
assert.strictEqual(await element.getText(), 'Hello from JavaScript!');
  
driver.get("https://google.com/ncr")
driver.findElement(By.name("q")).sendKeys("cheese" + Keys.ENTER)
// Initialize and wait till element(link) became clickable - timeout in 10 seconds
val firstResult = WebDriverWait(driver, Duration.ofSeconds(10))
      .until(ExpectedConditions.elementToBeClickable(By.xpath("//a/h3")))
// Print the first result
println(firstResult.text)
  

Passamos a condição como uma referência de função que o wait executará repetidamente até que seu valor de retorno seja verdadeiro. Um valor de retorno “verdadeiro” é qualquer coisa avaliada como booleana verdadeira na linguagem em questão, como string, número, booleano, um objeto (incluindo um WebElement), ou uma sequência ou lista preenchida (não vazia). Isso significa que uma lista vazia é avaliada como falsa. Quando a condição é verdadeira e a espera de bloqueio é abortada, o valor de retorno da condição se torna o valor de retorno da espera.

Com este conhecimento, e como o utilitário de espera ignora erros no such element por padrão, podemos refatorar nossas instruções para sermos mais concisos:

WebElement foo = new WebDriverWait(driver, Duration.ofSeconds(3))
          .until(driver -> driver.findElement(By.name("q")));
assertEquals(foo.getText(), "Hello from JavaScript!");
  
from selenium.webdriver.support.wait import WebDriverWait

driver.navigate("file:///race_condition.html")
el = WebDriverWait(driver, timeout=3).until(lambda d: d.find_element(By.TAG_NAME,"p"))
assert el.text == "Hello from JavaScript!"
  
   using (var driver = new FirefoxDriver())
    {
        var foo = new WebDriverWait(driver, TimeSpan.FromSeconds(3))
                        .Until(drv => drv.FindElement(By.Name("q")));
        Debug.Assert(foo.Text.Equals("Hello from JavaScript!"));
    }
  
  driver.get 'file:///race_condition.html'
  wait = Selenium::WebDriver::Wait.new(:timeout => 10)
  ele = wait.until { driver.find_element(css: 'p')}
  foo = ele.text
  assert_match foo, 'Hello from JavaScript'
  
let ele = await driver.wait(until.elementLocated(By.css('p')),10000);
let foo = await ele.getText();
assert(foo == "Hello from JavaScript");
  
driver.get("file:///race_condition.html")
val ele = WebDriverWait(driver, Duration.ofSeconds(10))
            .until(ExpectedConditions.presenceOfElementLocated(By.tagName("p")))
assert(ele.text == "Hello from JavaScript!")
  

Nesse exemplo, passamos uma função anônima (mas também podemos definá-la explicitamente, como fizemos antes, para que possa ser reutilizado). O primeiro e único argumento que é passado para nossa condição é sempre uma referência ao nosso objeto driver, WebDriver. Em um ambiente multi-thread, você deve ter cuidado para operar na referência do driver passada para a condição em vez da referência ao driver no escopo externo.

Dado que a espera vai engolir erros no such element que são gerados quando o elemento não é encontrado, a condição tentará novamente até que o elemento seja encontrado. Em seguida, ele receberá o valor de retorno, um WebElement, e o passará de volta para o nosso script.

Se a condição falhar, por exemplo um valor de retorno verdadeiro da condição nunca for alcançado, a espera lançará/gerará um erro/exceção chamado timeout error.

Opções

A condição de espera pode ser personalizada para atender às suas necessidades. Às vezes, é desnecessário esperar todo o tempo limite padrão, já que a penalidade por não atingir uma condição de sucesso pode ser cara.

A espera permite que você passe um argumento para substituir o tempo limite:

new WebDriverWait(driver, Duration.ofSeconds(3)).until(ExpectedConditions.elementToBeClickable(By.xpath("//a/h3")));
  
WebDriverWait(driver, timeout=3).until(some_condition)
  
new WebDriverWait(driver, TimeSpan.FromSeconds(3)).Until(driver => driver.FindElement(By.Name("q")));
  
wait = Selenium::WebDriver::Wait.new(:timeout => 10)

wait.until { driver.find_element(:id, 'message').displayed? }
  
  await driver.wait(until.elementLocated(By.id('foo')), 30000);
  
WebDriverWait(driver, Duration.ofSeconds(3)).until(ExpectedConditions.elementToBeClickable(By.xpath("//a/h3")))
  

Condições esperadas

Já que é uma ocorrência bastante comum ter que sincronizar o DOM e suas instruções, a maioria dos clientes também vem com um conjunto de condições esperadas predefinidas. Como pode ser óbvio pelo nome, são condições predefinidas para operações de espera frequentes.

As condições disponíveis nas diferentes linguagens variam, mas esta é uma lista não exaustiva de alguns:

  • alert is present
  • element exists
  • element is visible
  • title contains
  • title is
  • element staleness
  • visible text

Você pode consultar a documentação da API para cada biblioteca de cliente para encontrar uma lista exaustiva das condições esperadas:

Espera implícita

Há um segundo tipo de espera que é diferente de espera explícita chamada espera implícita. Esperando implicitamente, o WebDriver pesquisa o DOM por um certo período ao tentar encontrar qualquer elemento. Isso pode ser útil quando certos elementos da página da web não estão disponíveis imediatamente e precisam de algum tempo para carregar.

A espera implícita pelo aparecimento de elementos está desativada por padrão e precisará ser habilitada manualmente por sessão. Misturar esperas explícitas e esperas implícitas irá causar consequências não intencionais, ou seja, espera dormir pelo máximo tempo mesmo se o elemento estiver disponível ou a condição for verdadeira.

Atenção: Não misture esperas implícitas e explícitas. Isso pode causar tempos de espera imprevisíveis. Por exemplo, definir uma espera implícita de 10 segundos e uma espera explícita de 15 segundos pode causar um tempo limite após 20 segundos.

Uma espera implícita é dizer ao WebDriver para pesquisar o DOM por um certo período de tempo ao tentar encontrar um elemento ou elementos se não estiverem imediatamente disponíveis. A configuração padrão é 0, o que significa desativado. Depois de definida, a espera implícita é definida para a duração da sessão.

WebDriver driver = new FirefoxDriver();
driver.manage().timeouts().implicitlyWait(Duration.ofSeconds(10));
driver.get("http://somedomain/url_that_delays_loading");
WebElement myDynamicElement = driver.findElement(By.id("myDynamicElement"));
  
driver = Firefox()
driver.implicitly_wait(10)
driver.get("http://somedomain/url_that_delays_loading")
my_dynamic_element = driver.find_element(By.ID, "myDynamicElement")
  
IWebDriver driver = new ChromeDriver();
driver.Manage().Timeouts().ImplicitWait = TimeSpan.FromSeconds(10);
driver.Url = "http://somedomain/url_that_delays_loading";
IWebElement dynamicElement = driver.FindElement(By.Name("dynamicElement"));
  
require 'selenium-webdriver'
driver = Selenium::WebDriver.for :firefox
driver.manage.timeouts.implicit_wait = 10

begin
  driver.get 'http://somedomain/url_that_delays_loading'
  search_form = driver.find_element(:id,'dynamic_element')
ensure
  driver.quit
end
  
(async function(){

// Apply timeout for 10 seconds
await driver.manage().setTimeouts( { implicit: 10000 } );

// Navigate to url
await driver.get('http://somedomain/url_that_delays_loading');

let webElement = driver.findElement(By.id("myDynamicElement"));

}());
  
val driver = FirefoxDriver()
driver.manage().timeouts().implicitlyWait(Duration.ofSeconds(10))
driver.get("http://somedomain/url_that_delays_loading")
val myDynamicElement = driver.findElement(By.id("myDynamicElement"))
  

FluentWait

A instância FluentWait define a quantidade máxima de tempo de espera por uma condição, bem como a frequência com que verificar a condição.

Os usuários podem configurar a espera para ignorar tipos específicos de exceções enquanto esperam, como NoSuchElementException ao pesquisar um elemento na página.

// Waiting 30 seconds for an element to be present on the page, checking
// for its presence once every 5 seconds.
Wait<WebDriver> wait = new FluentWait<WebDriver>(driver)
  .withTimeout(Duration.ofSeconds(30))
  .pollingEvery(Duration.ofSeconds(5))
  .ignoring(NoSuchElementException.class);

WebElement foo = wait.until(driver -> {
  return driver.findElement(By.id("foo"));
});
  
driver = Firefox()
driver.get("http://somedomain/url_that_delays_loading")
wait = WebDriverWait(driver, timeout=10, poll_frequency=1, ignored_exceptions=[ElementNotVisibleException, ElementNotSelectableException])
element = wait.until(EC.element_to_be_clickable((By.XPATH, "//div")))
  
using (var driver = new FirefoxDriver())
{
  WebDriverWait wait = new WebDriverWait(driver, timeout: TimeSpan.FromSeconds(30))
  {
      PollingInterval = TimeSpan.FromSeconds(5),
  };
  wait.IgnoreExceptionTypes(typeof(NoSuchElementException));

  var foo = wait.Until(drv => drv.FindElement(By.Id("foo")));
}
  
require 'selenium-webdriver'
driver = Selenium::WebDriver.for :firefox
exception = Selenium::WebDriver::Error::NoSuchElementError

begin
  driver.get 'http://somedomain/url_that_delays_loading'
  wait = Selenium::WebDriver::Wait.new(timeout: 30, interval: 5, message: 'Timed out after 30 sec', ignore: exception)
  foo = wait.until { driver.find_element(id: 'foo')}
ensure
  driver.quit
end
  
const {Builder, until} = require('selenium-webdriver');

(async function example() {
    let driver = await new Builder().forBrowser('firefox').build();
    await driver.get('http://somedomain/url_that_delays_loading');
    // Waiting 30 seconds for an element to be present on the page, checking
    // for its presence once every 5 seconds.
    let foo = await driver.wait(until.elementLocated(By.id('foo')), 30000, 'Timed out after 30 seconds', 5000);
})();
  
val wait = FluentWait<WebDriver>(driver)
        .withTimeout(Duration.ofSeconds(30))
        .pollingEvery(Duration.ofSeconds(3))
        .ignoring(NoSuchElementException::class.java)

val foo = wait.until {it.findElement(By.id("foo")) }

Identificando e trabalhando com elementos no DOM.

A maioria do código que é escrito recorrendo às bibliotecas Selenium envolve trabalhar com elementos.

5.1 - File Upload

Como subir arquivos com Selenium

A caixa de diálogo para o envio de arquivos pode ser tratada com o Selenium, quando o elemento de entrada é do tipo “file”. Pode observar um exemplo neste link https://the-internet.herokuapp.com/upload .

Será necessário ter o arquivo a subir disponível para a operação. Apresentamos alguns exemplos de código para subir os arquivos em diversas linguagens de programação:

import java.util.concurrent.TimeUnit;
import org.openqa.selenium.By;
import org.openqa.selenium.WebDriver;
import org.openqa.selenium.chrome.ChromeDriver;
class fileUploadDoc{
	public static void main(String[] args) {
		WebDriver driver = new ChromeDriver();
		driver.manage().timeouts().implicitlyWait(10, TimeUnit.SECONDS);
		driver.get("https://the-internet.herokuapp.com/upload");
		//we want to import selenium-snapshot file. 
		driver.findElement(By.id("file-upload")).sendKeys("selenium-snapshot.jpg");
		driver.findElement(By.id("file-submit")).submit();
		if(driver.getPageSource().contains("File Uploaded!")) {
			System.out.println("file uploaded");
		}
		else{
				System.out.println("file not uploaded");
			}
		driver.quit();
	}
}

  
from selenium import webdriver
driver.implicitly_wait(10)
driver.get("https://the-internet.herokuapp.com/upload");
driver.find_element(By.ID,"file-upload").send_keys("selenium-snapshot.jpg")
driver.find_element(By.ID,"file-submit").submit()
if(driver.page_source.find("File Uploaded!")):
    print("file upload success")
else:
    print("file upload not successful")
driver.quit()

5.2 - Encontrando Elementos Web

Localizando elementos com base nos valores providenciados pelo localizador.

Um dos aspectos mais fundamentais do uso do Selenium é obter referências de elementos para trabalhar. O Selenium oferece várias estratégias de localizador para identificar exclusivamente um elemento. Há muitas maneiras de usar os localizadores em cenários complexos. Para os propósitos desta documentação, vamos considerar este trecho de HTML:

<ol id="vegetables">
 <li class="potatoes"> <li class="onions"> <li class="tomatoes"><span>O tomate é um vegetal</span></ol>
<ul id="fruits">
  <li class="bananas">  <li class="apples">  <li class="tomatoes"><span>O tomate é uma fruta</span></ul>

Primeiro Elemento correspondente

Muitos localizadores irão corresponder a vários elementos na página. O método de elemento de localização singular retornará uma referência ao primeiro elemento encontrado dentro de um determinado contexto.

Avaliando o DOM inteiro

Quando o metodo find element é chamado na instância do driver, ele retorna uma referência ao primeiro elemento no DOM que corresponde ao localizador fornecido. Esse valor pode ser guardado e usado para ações futuras do elemento. Em nosso exemplo HTML acima, existem dois elementos que têm um nome de classe de “tomatoes” então este método retornará o elemento na lista “vegetables”.

WebElement vegetable = driver.findElement(By.className("tomatoes"));
  
vegetable = driver.find_element(By.CLASS_NAME, "tomatoes")
  
var vegetable = driver.FindElement(By.ClassName("tomatoes"));
  
vegetable = driver.find_element(class: 'tomatoes')
  
const vegetable = await driver.findElement(By.className('tomatoes'));
  
val vegetable: WebElement = driver.findElement(By.className("tomatoes"))
  

Avaliando um subconjunto do DOM

Ao em vez de tentar encontrar um localizador unico no DOM inteiro, normalmente é útil restringir a busca ao escopo de outro elemento já localizado. No exemplo acima existem dois elementos com um nome de classe de “tomatoes” e é um pouco mais desafiador obter a referência para o segundo.

Uma possível solução seria localizar um elemento com um atributo único que seja um ancestral do elemento desejado e não um ancestral do elemento indesejado, então invoque o find element nesse objeto:

WebElement fruits = driver.findElement(By.id("fruits"));
WebElement fruit = fruits.findElement(By.className("tomatoes"));
  
fruits = driver.find_element(By.ID, "fruits")
fruit = fruits.find_element(By.CLASS_NAME,"tomatoes")
  
IWebElement fruits = driver.FindElement(By.Id("fruits"));
IWebElement fruit = fruits.FindElement(By.ClassName("tomatoes"));
  
fruits = driver.find_element(id: 'fruits')
fruit = fruits.find_element(class: 'tomatoes')
  
const fruits = await driver.findElement(By.id('fruits'));
const fruit = fruits.findElement(By.className('tomatoes'));
  
val fruits = driver.findElement(By.id("fruits"))
val fruit = fruits.findElement(By.className("tomatoes"))
  

Java e C#
As classes WebDriver, WebElement e ShadowRoot todas implementam o SearchContext interface, que é considerada uma role-based interface(interface baseada em função). As interfaces baseadas em função permitem determinar se uma determinada implementação de driver suporta um recurso específico. Essas interfaces são claramente definidas e tentam aderir a ter apenas um único papel de responsabilidade.

Localizador otimizado

Uma pesquisa aninhada pode não ser a estratégia de localização mais eficaz, pois requer dois comandos separados a serem emitidos para o navegador.

Para melhorar um pouco o desempenho, podemos usar CSS ou XPath para encontrar esse elemento com um único comando. Veja as sugestões de estratégia do localizador na nossa sessão de Práticas de teste incentivadas.

Para esse exemplo, utilizaremos o CSS Selector:

WebElement fruit = driver.findElement(By.cssSelector("#fruits .tomatoes"));
  
fruit = driver.find_element(By.CSS_SELECTOR,"#fruits .tomatoes")
  
var fruit = driver.FindElement(By.CssSelector("#fruits .tomatoes"));
  
fruit = driver.find_element(css: '#fruits .tomatoes')
  
const fruit = await driver.findElement(By.css('#fruits .tomatoes'));
  
val fruit = driver.findElement(By.cssSelector("#fruits .tomatoes"))
  

Todos os elementos correspondentes

Existem vários casos de uso para a necessidade de obter referências a todos os elementos que correspondem a um localizador, em vez do que apenas o primeiro. Os métodos plurais find elements retornam uma coleção de referências de elementos. Se não houver correspondências, uma lista vazia será retornada. Nesse caso, referências a todos os itens da lista de frutas e vegetais serão devolvidas em uma coleção.

List<WebElement> plants = driver.findElements(By.tagName("li"));
  
plants = driver.find_elements(By.TAG_NAME, "li")
  
IReadOnlyList<IWebElement> plants = driver.FindElements(By.TagName("li"));
  
plants = driver.find_elements(tag_name: 'li')
  
const plants = await driver.findElements(By.tagName('li'));
  
val plants: List<WebElement> = driver.findElements(By.tagName("li"))
  

Obter Elemento

Muitas vezes você obterá uma coleção de elementos, mas quer trabalhar apenas com um elemento específico, o que significa que você precisa iterar sobre a coleção e identificar o que você deseja.

List<WebElement> elements = driver.findElements(By.tagName("li"));

for (WebElement element : elements) {
    System.out.println("Paragraph text:" + element.getText());
}

Localizar Elementos em um Elemento

Ele é usado para localizar a lista de WebElements filhos correspondentes dentro do contexto do elemento pai. Para realizar isso, o WebElement pai é encadeado com o ‘findElements’ para acessar seus elementos filhos.

5.3 - Interacting with web elements

A high-level instruction set for manipulating form controls.

There are only 5 basic commands that can be executed on an element:

  • click (applies to any element)
  • send keys (only applies to text fields and content editable elements)
  • clear (only applies to text fields and content editable elements)
  • submit (only applies to form elements)
  • select (see Select List Elements)

Additional validations

These methods are designed to closely emulate a user’s experience, so, unlike the Actions API, it attempts to perform two things before attempting the specified action.

  1. If it determines the element is outside the viewport, it scrolls the element into view, specifically it will align the bottom of the element with the bottom of the viewport.
  2. It ensures the element is interactable before taking the action. This could mean that the scrolling was unsuccessful, or that the element is not otherwise displayed. Determining if an element is displayed on a page was too difficult to define directly in the webdriver specification, so Selenium sends an execute command with a JavaScript atom that checks for things that would keep the element from being displayed. If it determines an element is not in the viewport, not displayed, not keyboard-interactable, or not pointer-interactable, it returns an element not interactable error.

Click

The element click command is executed on the center of the element. If the center of the element is obscured for some reason, Selenium will return an element click intercepted error.

Send keys

The element send keys command types the provided keys into an editable element. Typically, this means an element is an input element of a form with a text type or an element with a content-editable attribute. If it is not editable, an invalid element state error is returned.

Here is the list of possible keystrokes that WebDriver Supports.

import org.openqa.selenium.By;
import org.openqa.selenium.Keys;
import org.openqa.selenium.WebDriver;
import org.openqa.selenium.firefox.FirefoxDriver;

public class HelloSelenium {
public static void main(String[] args) {
WebDriver driver = new FirefoxDriver();
try {
// Navigate to Url
driver.get("https://google.com");

      // Enter text "q" and perform keyboard action "Enter"
      driver.findElement(By.name("q")).sendKeys("q" + Keys.ENTER);
    } finally {
      driver.quit();
    }

    // Enter text "q" and perform keyboard action "Enter"
    driver.findElement(By.name("q")).sendKeys("q" + Keys.ENTER)
} finally {
driver.quit()
}
}

Clear

The element clear command resets the content of an element. This requires an element to be editable, and resettable. Typically, this means an element is an input element of a form with a text type or an element with acontent-editable attribute. If these conditions are not met, an invalid element state error is returned.

import org.openqa.selenium.By;

try {
// Navigate to Url
driver.get("https://www.google.com");
// Store 'SearchInput' element
WebElement searchInput = driver.findElement(By.name("q"));
searchInput.sendKeys("selenium");
// Clears the entered text
searchInput.clear();
} finally {

ensure
driver.quit
end
        await driver.get('https://www.selenium.dev/selenium/web/inputs.html');
        let inputField = await driver.findElement(By.name('no_type'));
        await inputField.clear();

}

Submit

In Selenium 4 this is no longer implemented with a separate endpoint and functions by executing a script. As such, it is recommended not to use this method and to click the applicable form submission button instead.

5.4 - Information about web elements

What you can learn about an element.

There are a number of details you can query about a specific element.

Is Displayed

This method is used to check if the connected Element is displayed on a webpage. Returns a Boolean value, True if the connected element is displayed in the current browsing context else returns false.

This functionality is mentioned in, but not defined by the w3c specification due to the impossibility of covering all potential conditions. As such, Selenium cannot expect drivers to implement this functionality directly, and now relies on executing a large JavaScript function directly. This function makes many approximations about an element’s nature and relationship in the tree to return a value.

// Navigate to the url
driver.get("https://www.selenium.dev/selenium/web/inputs.html");

// Get boolean value for is element display
boolean isEmailVisible = driver.findElement(By.name("email_input")).isDisplayed();
# Navigate to the url
driver.get("https://www.selenium.dev/selenium/web/inputs.html")

# Get boolean value for is element display
is_email_visible = driver.find_element(By.NAME, "email_input").is_displayed()
//Navigate to the url
driver.Url = "https://www.selenium.dev/selenium/web/inputs.html";

//Get boolean value for is element display
Boolean is_email_visible = driver.FindElement(By.Name("email_input")).Displayed;
# Navigate to the url
driver.get("https://www.selenium.dev/selenium/web/inputs.html");

#fetch display status
val = driver.find_element(name: 'email_input').displayed?
// Navigate to url
await driver.get("https://www.selenium.dev/selenium/web/inputs.html");

// Resolves Promise and returns boolean value
let result =  await driver.findElement(By.name("email_input")).isDisplayed();
//navigates to url
 driver.get("https://www.selenium.dev/selenium/web/inputs.html")

 //returns true if element is displayed else returns false
 val flag = driver.findElement(By.name("email_input")).isDisplayed()

Elemento está selecionado

Este método determina se o elemento referenciado é Selected ou não. Este método é amplamente utilizado em caixas de seleção, botões de opção, elementos de entrada e elementos de opção.

Retorna um valor booleano, true se o elemento referenciado for selected no contexto de navegação atual, caso contrário, retorna false.

//navigates to url
driver.get("https://the-internet.herokuapp.com/checkboxes");

//returns true if element is checked else returns false

5.5 - Localizando elementos

Formas de identificar um ou mais elementos no DOM.

Um localizador é uma forma de identificar elementos numa página. São os argumentos passados aos métodos Finders .

Visite os nossas directrizes e recomendações para dicas sobre locators, incluindo quais usar e quando, e também porque é que deve declarar localizadores separadamente dos finders.

Estratégias de seleção de elemento

Existem oito estratégias diferentes de localização de elementos embutidas no WebDriver:

Localizador Descrição
class name Localiza elementos cujo nome de classe contém o valor de pesquisa (nomes de classes compostas não são permitidos)
css selector Localiza elementos que correspondem a um seletor CSS
id Localiza elementos cujo atributo de ID corresponde ao valor de pesquisa
name Localiza elementos cujo atributo NAME corresponde ao valor de pesquisa
link text Localiza elementos âncora cujo texto visível corresponde ao valor de pesquisa
partial link text Localiza elementos âncora cujo texto visível contém o valor da pesquisa. Se vários elementos forem correspondentes, apenas o primeiro será selecionado.
tag name Localiza elementos cujo nome de tag corresponde ao valor de pesquisa
xpath Localiza elementos que correspondem a uma expressão XPath

Creating Locators

To work on a web element using Selenium, we need to first locate it on the web page. Selenium provides us above mentioned ways, using which we can locate element on the page. To understand and create locator we will use the following HTML snippet.

<html>
<body>
<style>
.information {
  background-color: white;
  color: black;
  padding: 10px;
}
</style>
<h2>Contact Selenium</h2>

<form action="/action_page.php">
  <input type="radio" name="gender" value="m" />Male &nbsp;
  <input type="radio" name="gender" value="f" />Female <br>
  <br>
  <label for="fname">First name:</label><br>
  <input class="information" type="text" id="fname" name="fname" value="Jane"><br><br>
  <label for="lname">Last name:</label><br>
  <input class="information" type="text" id="lname" name="lname" value="Doe"><br><br>
  <label for="newsletter">Newsletter:</label>
  <input type="checkbox" name="newsletter" value="1" /><br><br>
  <input type="submit" value="Submit">
</form>

</html>

class name

The HTML page web element can have attribute class. We can see an example in the above shown HTML snippet. We can identify these elements using the class name locator available in Selenium.

    WebDriver driver = new ChromeDriver();
	driver.findElement(By.className("information"));
  
    driver = webdriver.Chrome()
	driver.find_element(By.CLASS_NAME, "information")
  
    var driver = new ChromeDriver();
	driver.FindElement(By.ClassName("information"));
  
    driver = Selenium::WebDriver.for :chrome
	driver.find_element(class: 'information')
  
    let driver = await new Builder().forBrowser('chrome').build();
	const loc = await driver.findElement(By.className('information'));
  
    val driver = ChromeDriver()
	val loc: WebElement = driver.findElement(By.className("information"))
  

css selector

CSS is the language used to style HTML pages. We can use css selector locator strategy to identify the element on the page. If the element has an id, we create the locator as css = #id. Otherwise the format we follow is css =[attribute=value] . Let us see an example from above HTML snippet. We will create locator for First Name textbox, using css.

    WebDriver driver = new ChromeDriver();
	driver.findElement(By.cssSelector("#fname"));
  
    driver = webdriver.Chrome()
	driver.find_element(By.CSS_SELECTOR, "#fname")
  
    var driver = new ChromeDriver();
	driver.FindElement(By.CssSelector("#fname"));
  
    driver = Selenium::WebDriver.for :chrome
	driver.find_element(css: '#fname')
  
    let driver = await new Builder().forBrowser('chrome').build();
	const loc = await driver.findElement(By.css('#fname'));
  
    val driver = ChromeDriver()
	val loc: WebElement = driver.findElement(By.css("#fname"))
  

id

We can use the ID attribute available with element in a web page to locate it. Generally the ID property should be unique for a element on the web page. We will identify the Last Name field using it.

    WebDriver driver = new ChromeDriver();
	driver.findElement(By.id("lname"));
  
    driver = webdriver.Chrome()
	driver.find_element(By.ID, "lname")
  
    var driver = new ChromeDriver();
	driver.FindElement(By.Id("lname"));
  
    driver = Selenium::WebDriver.for :chrome
	driver.find_element(id: 'lname')
  
    let driver = await new Builder().forBrowser('chrome').build();
	const loc = await driver.findElement(By.id('lname'));
  
    val driver = ChromeDriver()
	val loc: WebElement = driver.findElement(By.id("lname"))
  

name

We can use the NAME attribute available with element in a web page to locate it. Generally the NAME property should be unique for a element on the web page. We will identify the Newsletter checkbox using it.

    WebDriver driver = new ChromeDriver();
	driver.findElement(By.name("newsletter"));
  
    driver = webdriver.Chrome()
	driver.find_element(By.NAME, "newsletter")
  
    var driver = new ChromeDriver();
	driver.FindElement(By.Name("newsletter"));
  
    driver = Selenium::WebDriver.for :chrome
	driver.find_element(name: 'newsletter')
  
    let driver = await new Builder().forBrowser('chrome').build();
	const loc = await driver.findElement(By.name('newsletter'));
  
    val driver = ChromeDriver()
	val loc: WebElement = driver.findElement(By.name("newsletter"))
  

If the element we want to locate is a link, we can use the link text locator to identify it on the web page. The link text is the text displayed of the link. In the HTML snippet shared, we have a link available, lets see how will we locate it.

    WebDriver driver = new ChromeDriver();
	driver.findElement(By.linkText("Selenium Official Page"));
  
    driver = webdriver.Chrome()
	driver.find_element(By.LINK_TEXT, "Selenium Official Page")
  
    var driver = new ChromeDriver();
	driver.FindElement(By.LinkText("Selenium Official Page"));
  
    driver = Selenium::WebDriver.for :chrome
	driver.find_element(link_text: 'Selenium Official Page')
  
    let driver = await new Builder().forBrowser('chrome').build();
	const loc = await driver.findElement(By.linkText('Selenium Official Page'));
  
    val driver = ChromeDriver()
	val loc: WebElement = driver.findElement(By.linkText("Selenium Official Page"))
  

If the element we want to locate is a link, we can use the partial link text locator to identify it on the web page. The link text is the text displayed of the link. We can pass partial text as value. In the HTML snippet shared, we have a link available, lets see how will we locate it.

    WebDriver driver = new ChromeDriver();
	driver.findElement(By.partialLinkText("Official Page"));
  
    driver = webdriver.Chrome()
	driver.find_element(By.PARTIAL_LINK_TEXT, "Official Page")
  
    var driver = new ChromeDriver();
	driver.FindElement(By.PartialLinkText("Official Page"));
  
    driver = Selenium::WebDriver.for :chrome
	driver.find_element(partial_link_text: 'Official Page')
  
    let driver = await new Builder().forBrowser('chrome').build();
	const loc = await driver.findElement(By.partialLinkText('Official Page'));
  
    val driver = ChromeDriver()
	val loc: WebElement = driver.findElement(By.partialLinkText("Official Page"))
  

tag name

We can use the HTML TAG itself as a locator to identify the web element on the page. From the above HTML snippet shared, lets identify the link, using its html tag “a”.

    WebDriver driver = new ChromeDriver();
	driver.findElement(By.tagName("a"));
  
    driver = webdriver.Chrome()
	driver.find_element(By.TAG_NAME, "a")
  
    var driver = new ChromeDriver();
	driver.FindElement(By.TagName("a"));
  
    driver = Selenium::WebDriver.for :chrome
	driver.find_element(tag_name: 'a')
  
    let driver = await new Builder().forBrowser('chrome').build();
	const loc = await driver.findElement(By.tagName('a'));
  
    val driver = ChromeDriver()
	val loc: WebElement = driver.findElement(By.tagName("a"))
  

xpath

A HTML document can be considered as a XML document, and then we can use xpath which will be the path traversed to reach the element of interest to locate the element. The XPath could be absolute xpath, which is created from the root of the document. Example - /html/form/input[1]. This will return the male radio button. Or the xpath could be relative. Example- //input[@name=‘fname’]. This will return the first name text box. Let us create locator for female radio button using xpath.

    WebDriver driver = new ChromeDriver();
	driver.findElement(By.xpath("//input[@value='f']"));
  
    driver = webdriver.Chrome()
	driver.find_element(By.XPATH, "//input[@value='f']")
  
    var driver = new ChromeDriver();
	driver.FindElement(By.Xpath("//input[@value='f']"));
  
    driver = Selenium::WebDriver.for :chrome
	driver.find_element(xpath: '//input[@value='f']')
  
    let driver = await new Builder().forBrowser('chrome').build();
	const loc = await driver.findElement(By.xpath('//input[@value='f']'));
  
    val driver = ChromeDriver()
	val loc: WebElement = driver.findElement(By.xpath('//input[@value='f']'))
  

Relative Locators

Selenium 4 introduces Relative Locators (previously called as Friendly Locators). These locators are helpful when it is not easy to construct a locator for the desired element, but easy to describe spatially where the element is in relation to an element that does have an easily constructed locator.

How it works

Selenium uses the JavaScript function getBoundingClientRect() to determine the size and position of elements on the page, and can use this information to locate neighboring elements.
find the relative elements.

Relative locator methods can take as the argument for the point of origin, either a previously located element reference, or another locator. In these examples we’ll be using locators only, but you could swap the locator in the final method with an element object and it will work the same.

Let us consider the below example for understanding the relative locators.

Relative Locators

Available relative locators

Above

If the email text field element is not easily identifiable for some reason, but the password text field element is, we can locate the text field element using the fact that it is an “input” element “above” the password element.

By emailLocator = RelativeLocator.with(By.tagName("input")).above(By.id("password"));
email_locator = locate_with(By.TAG_NAME, "input").above({By.ID: "password"})
var emailLocator = RelativeBy.WithLocator(By.TagName("input")).Above(By.Id("password"));
email_locator = {relative: {tag_name: 'input', above: {id: 'password'}}}
let emailLocator = locateWith(By.tagName('input')).above(By.id('password'));
val emailLocator = RelativeLocator.with(By.tagName("input")).above(By.id("password"))

Below

If the password text field element is not easily identifiable for some reason, but the email text field element is, we can locate the text field element using the fact that it is an “input” element “below” the email element.

By passwordLocator = RelativeLocator.with(By.tagName("input")).below(By.id("email"));
password_locator = locate_with(By.TAG_NAME, "input").below({By.ID: "email"})
var passwordLocator = RelativeBy.WithLocator(By.TagName("input")).Below(By.Id("email"));
password_locator = {relative: {tag_name: 'input', below: {id: 'email'}}}
let passwordLocator = locateWith(By.tagName('input')).below(By.id('email'));
val passwordLocator = RelativeLocator.with(By.tagName("input")).below(By.id("email"))

Left of

If the cancel button is not easily identifiable for some reason, but the submit button element is, we can locate the cancel button element using the fact that it is a “button” element to the “left of” the submit element.

By cancelLocator = RelativeLocator.with(By.tagName("button")).toLeftOf(By.id("submit"));
cancel_locator = locate_with(By.TAG_NAME, "button").to_left_of({By.ID: "submit"})
var cancelLocator = RelativeBy.WithLocator(By.tagName("button")).LeftOf(By.Id("submit"));
cancel_locator = {relative: {tag_name: 'button', left: {id: 'submit'}}}
let cancelLocator = locateWith(By.tagName('button')).toLeftOf(By.id('submit'));
val cancelLocator = RelativeLocator.with(By.tagName("button")).toLeftOf(By.id("submit"))

Right of

If the submit button is not easily identifiable for some reason, but the cancel button element is, we can locate the submit button element using the fact that it is a “button” element “to the right of” the cancel element.

By submitLocator = RelativeLocator.with(By.tagName("button")).toRightOf(By.id("cancel"));
submit_locator = locate_with(By.TAG_NAME, "button").to_right_of({By.ID: "cancel"})
var submitLocator = RelativeBy.WithLocator(By.tagName("button")).RightOf(By.Id("cancel"));
submit_locator = {relative: {tag_name: 'button', right: {id: 'cancel'}}}
let submitLocator = locateWith(By.tagName('button')).toRightOf(By.id('cancel'));
val submitLocator = RelativeLocator.with(By.tagName("button")).toRightOf(By.id("cancel"))

Near

If the relative positioning is not obvious, or it varies based on window size, you can use the near method to identify an element that is at most 50px away from the provided locator. One great use case for this is to work with a form element that doesn’t have an easily constructed locator, but its associated input label element does.

By emailLocator = RelativeLocator.with(By.tagName("input")).near(By.id("lbl-email"));
email_locator = locate_with(By.TAG_NAME, "input").near({By.ID: "lbl-email"})
var emailLocator = RelativeBy.WithLocator(By.tagName("input")).Near(By.Id("lbl-email"));
email_locator = {relative: {tag_name: 'input', near: {id: 'lbl-email'}}}
let emailLocator = locateWith(By.tagName('input')).near(By.id('lbl-email'));
val emailLocator = RelativeLocator.with(By.tagName("input")).near(By.id("lbl-email"));

Chaining relative locators

You can also chain locators if needed. Sometimes the element is most easily identified as being both above/below one element and right/left of another.

By submitLocator = RelativeLocator.with(By.tagName("button")).below(By.id("email")).toRightOf(By.id("cancel"));
submit_locator = locate_with(By.TAG_NAME, "button").below({By.ID: "email"}).to_right_of({By.ID: "cancel"})
var submitLocator = RelativeBy.WithLocator(By.tagName("button")).Below(By.Id("email")).RightOf(By.Id("cancel"));
submit_locator = {relative: {tag_name: 'button', below: {id: 'email'}, right: {id: 'cancel'}}}
let submitLocator = locateWith(By.tagName('button')).below(By.id('email')).toRightOf(By.id('cancel'));
val submitLocator = RelativeLocator.with(By.tagName("button")).below(By.id("email")).toRightOf(By.id("cancel"))

6.2 - Alertas, prompts e confirmações JavaScript

WebDriver fornece uma API para trabalhar com os três tipos nativos de mensagens pop-up oferecidas pelo JavaScript. Esses pop-ups são estilizados pelo navegador e oferecem personalização limitada.

Alertas

O mais simples deles é referido como um alerta, que mostra um mensagem personalizada e um único botão que dispensa o alerta, rotulado na maioria dos navegadores como OK. Ele também pode ser dispensado na maioria dos navegadores pressionando o botão Fechar, mas isso sempre fará a mesma coisa que o botão OK. Veja um exemplo de alerta .

O WebDriver pode obter o texto do pop-up e aceitar ou dispensar esses alertas.

//Click the link to activate the alert
driver.findElement(By.linkText("See an example alert")).click();

//Wait for the alert to be displayed and store it in a variable
Alert alert = wait.until(ExpectedConditions.alertIsPresent());

//Store the alert text in a variable
String text = alert.getText();

//Press the OK button
alert.accept();
  
# Click the link to activate the alert
driver.find_element(By.LINK_TEXT, "See an example alert").click()

# Wait for the alert to be displayed and store it in a variable
alert = wait.until(expected_conditions.alert_is_present())

# Store the alert text in a variable
text = alert.text

# Press the OK button
alert.accept()
  
//Click the link to activate the alert
driver.FindElement(By.LinkText("See an example alert")).Click();

//Wait for the alert to be displayed and store it in a variable
IAlert alert = wait.Until(ExpectedConditions.AlertIsPresent());

//Store the alert text in a variable
string text = alert.Text;

//Press the OK button
alert.Accept();
  
# Click the link to activate the alert
driver.find_element(:link_text, 'See an example alert').click

# Store the alert reference in a variable
alert = driver.switch_to.alert

# Store the alert text in a variable
alert_text = alert.text

# Press on OK button
alert.accept
  
//Click the link to activate the alert
await driver.findElement(By.linkText('See an example alert')).click();

// Wait for the alert to be displayed
await driver.wait(until.alertIsPresent());

// Store the alert in a variable
let alert = await driver.switchTo().alert();

//Store the alert text in a variable
let alertText = await alert.getText();

//Press the OK button
await alert.accept();

// Note: To use await, the above code should be inside an async function
  
//Click the link to activate the alert
driver.findElement(By.linkText("See an example alert")).click()

//Wait for the alert to be displayed and store it in a variable
val alert = wait.until(ExpectedConditions.alertIsPresent())

//Store the alert text in a variable
val text = alert.getText()

//Press the OK button
alert.accept()
  

Confirmação

Uma caixa de confirmação é semelhante a um alerta, exceto que o usuário também pode escolher cancelar a mensagem. Veja uma amostra de confirmação .

Este exemplo também mostra uma abordagem diferente para armazenar um alerta:

//Click the link to activate the alert
driver.findElement(By.linkText("See a sample confirm")).click();

//Wait for the alert to be displayed
wait.until(ExpectedConditions.alertIsPresent());

//Store the alert in a variable
Alert alert = driver.switchTo().alert();

//Store the alert in a variable for reuse
String text = alert.getText();

Prompt

Os prompts são semelhantes às caixas de confirmação, exceto que também incluem um texto de entrada. Semelhante a trabalhar com elementos de formulário, você pode usar o sendKeys do WebDriver para preencher uma resposta. Isso substituirá completamente o espaço de texto de exemplo. Pressionar o botão Cancelar não enviará nenhum texto. Veja um exemplo de prompt .

//Click the link to activate the alert
driver.findElement(By.linkText("See a sample prompt")).click();

//Wait for the alert to be displayed and store it in a variable
Alert alert = wait.until(ExpectedConditions.alertIsPresent());

//Type your message
alert.sendKeys("Selenium");

//Press the OK button
alert.accept();
  
# Click the link to activate the alert
driver.find_element(By.LINK_TEXT, "See a sample prompt").click()

# Wait for the alert to be displayed
wait.until(expected_conditions.alert_is_present())

6.3 - Trabalhando com cookies

Um cookie é um pequeno pedaço de dado enviado de um site e armazenado no seu computador. Os cookies são usados principalmente para reconhecer o usuário e carregar as informações armazenadas.

A API WebDriver fornece uma maneira de interagir com cookies com métodos integrados:

É usado para adicionar um cookie ao contexto de navegação atual. Add Cookie aceita apenas um conjunto de objetos JSON serializáveis definidos. Aqui é o link para a lista de valores-chave JSON aceitos.

Em primeiro lugar, você precisa estar no domínio para qual o cookie será valido. Se você está tentando predefinir cookies antes de começar a interagir com um site e sua página inicial é grande / demora um pouco para carregar uma alternativa é encontrar uma página menor no site (normalmente a página 404 é pequena, por exemplo http://example.com/some404page)

Permite que um usuário instrua os navegadores a controlar se os cookies são enviados junto com a solicitação iniciada por sites de terceiros. É usado para evitar ataques CSRF (Cross-Site Request Forgery).

O atributo de cookie Same-Site aceita dois parâmetros como instruções

Strict:

Quando o atributo sameSite é definido como Strict, o cookie não será enviado junto com solicitações iniciadas por sites de terceiros.

Lax:

Quando você define um atributo cookie sameSite como Lax, o cookie será enviado junto com uma solicitação GET iniciada por um site de terceiros.

Nota: a partir de agora, esse recurso está disponível no Chrome (versão 80+), Firefox (versão 79+) e funciona com Selenium 4 e versões posteriores.

6.4 - Working with IFrames and frames

Frames são um meio obsoleto de construir um layout de site a partir de vários documentos no mesmo domínio. É improvável que você trabalhe com eles a menos que você esteja trabalhando com um webapp pré-HTML5. Iframes permitem a inserção de um documento de um domínio totalmente diferente, e são ainda comumente usado.

Se você precisa trabalhar com frames ou iframes, o WebDriver permite que você trabalhe com eles da mesma maneira. Considere um botão dentro de um iframe. Se inspecionarmos o elemento usando as ferramentas de desenvolvimento do navegador, podemos ver o seguinte:

<div id="modal">
  <iframe id="buttonframe" name="myframe"  src="https://seleniumhq.github.io">
   <button>Click here</button>
 </iframe>
</div>

Se não fosse pelo iframe, esperaríamos clicar no botão usando algo como:

//This won't work
driver.findElement(By.tagName("button")).click();
  
    # This Wont work
driver.find_element(By.TAG_NAME, 'button').click()
  
//This won't work
driver.FindElement(By.TagName("button")).Click();
  
    # This won't work
driver.find_element(:tag_name,'button').click
  
// This won't work
await driver.findElement(By.css('button')).click();
  
//This won't work
driver.findElement(By.tagName("button")).click()
  

No entanto, se não houver botões fora do iframe, você pode em vez disso, obter um erro no such element. Isso acontece porque o Selenium é ciente apenas dos elementos no documento de nível superior. Para interagir com o botão, precisamos primeiro mudar para o quadro, de forma semelhante a como alternamos janelas. WebDriver oferece três maneiras de mudar para um frame.

Usando um WebElement

Alternar usando um WebElement é a opção mais flexível. Você pode encontrar o quadro usando seu seletor preferido e mudar para ele.

//Store the web element
WebElement iframe = driver.findElement(By.cssSelector("#modal>iframe"));

//Switch to the frame
driver.switchTo().frame(iframe);

//Now we can click the button
driver.findElement(By.tagName("button")).click();
  
    # Store iframe web element
iframe = driver.find_element(By.CSS_SELECTOR, "#modal > iframe")

    # switch to selected iframe
driver.switch_to.frame(iframe)

    # Now click on button
driver.find_element(By.TAG_NAME, 'button').click()
  
//Store the web element
IWebElement iframe = driver.FindElement(By.CssSelector("#modal>iframe"));

//Switch to the frame
driver.SwitchTo().Frame(iframe);

//Now we can click the button
driver.FindElement(By.TagName("button")).Click();
  
    # Store iframe web element
iframe = driver.find_element(:css,'#modal > iframe')

    # Switch to the frame
driver.switch_to.frame iframe

    # Now, Click on the button
driver.find_element(:tag_name,'button').click
  
// Store the web element
const iframe = driver.findElement(By.css('#modal > iframe'));

// Switch to the frame
await driver.switchTo().frame(iframe);

// Now we can click the button
await driver.findElement(By.css('button')).click();
  
//Store the web element
val iframe = driver.findElement(By.cssSelector("#modal>iframe"))

//Switch to the frame
driver.switchTo().frame(iframe)

//Now we can click the button
driver.findElement(By.tagName("button")).click()
  

Usando um name ou ID

Se o seu frame ou iframe tiver um atributo id ou name, ele pode ser usado alternativamente. Se o name ou ID não for exclusivo na página, o primeiro encontrado será utilizado.

//Using the ID
driver.switchTo().frame("buttonframe");

//Or using the name instead
driver.switchTo().frame("myframe");

//Now we can click the button
driver.findElement(By.tagName("button")).click();
  
    # Switch frame by id
driver.switch_to.frame('buttonframe')

    # Now, Click on the button
driver.find_element(By.TAG_NAME, 'button').click()
  
//Using the ID
driver.SwitchTo().Frame("buttonframe");

//Or using the name instead
driver.SwitchTo().Frame("myframe");

//Now we can click the button
driver.FindElement(By.TagName("button")).Click();
  
    # Switch by ID
driver.switch_to.frame 'buttonframe'

    # Now, Click on the button
driver.find_element(:tag_name,'button').click
  
// Using the ID
await driver.switchTo().frame('buttonframe');

// Or using the name instead
await driver.switchTo().frame('myframe');

// Now we can click the button
await driver.findElement(By.css('button')).click();
  
//Using the ID
driver.switchTo().frame("buttonframe")

//Or using the name instead
driver.switchTo().frame("myframe")

//Now we can click the button
driver.findElement(By.tagName("button")).click()
  

Usando um índice

Também é possível usar o índice do frame, podendo ser consultado usando window.frames em JavaScript.

// Switches to the second frame
driver.switchTo().frame(1);
  
    # Switch to the second frame
driver.switch_to.frame(1)
  
// Switches to the second frame
driver.SwitchTo().Frame(1);
  
    # switching to second iframe based on index
iframe = driver.find_elements(By.TAG_NAME,'iframe')[1]

    # switch to selected iframe
driver.switch_to.frame(iframe)
  
// Switches to the second frame
await driver.switchTo().frame(1);
  
// Switches to the second frame
driver.switchTo().frame(1)
  

Deixando um frame

Para deixar um iframe ou frameset, volte para o conteúdo padrão como a seguir:

// Return to the top level
driver.switchTo().defaultContent();
  
    # switch back to default content
driver.switch_to.default_content()
  
// Return to the top level
driver.SwitchTo().DefaultContent();
  
    # Return to the top level
driver.switch_to.default_content
  
// Return to the top level
await driver.switchTo().defaultContent();
  
// Return to the top level
driver.switchTo().defaultContent()
  

6.5 - Working with windows and tabs

Janelas e guias

Pegue o idenficador da janela

O WebDriver não faz distinção entre janelas e guias. E se seu site abre uma nova guia ou janela, o Selenium permitirá que você trabalhe usando um identificador. Cada janela tem um identificador único que permanece persistente em uma única sessão. Você pode pegar o identificador atual usando:

driver.getWindowHandle();
driver.current_window_handle
driver.CurrentWindowHandle;
driver.window_handle
await driver.getWindowHandle();
driver.windowHandle

Alternando janelas ou guias

Clicar em um link que abre em uma nova janela focará a nova janela ou guia na tela, mas o WebDriver não saberá qual janela que o sistema operacional considera ativa. Para trabalhar com a nova janela você precisará mudar para ela. Se você tiver apenas duas guias ou janelas abertas, e você sabe com qual janela você iniciou, pelo processo de eliminação você pode percorrer as janelas ou guias que o WebDriver pode ver e alternar para aquela que não é o original.

No entanto, o Selenium 4 fornece uma nova API NewWindow que cria uma nova guia (ou) nova janela e muda automaticamente para ela.

//Store the ID of the original window
String originalWindow = driver.getWindowHandle();

//Check we don't have other windows open already
assert driver.getWindowHandles().size() == 1;

//Click the link which opens in a new window
driver.findElement(By.linkText("new window")).click();

//Wait for the new window or tab
wait.until(numberOfWindowsToBe(2));

//Loop through until we find a new window handle
for (String windowHandle : driver.getWindowHandles()) {
    if(!originalWindow.contentEquals(windowHandle)) {
        driver.switchTo().window(windowHandle);
        break;
    }
}

//Wait for the new tab to finish loading content
wait.until(titleIs("Selenium documentation"));
  
from selenium import webdriver
from selenium.webdriver.support.ui import WebDriverWait
from selenium.webdriver.support import expected_conditions as EC

    # Start the driver

    # Setup wait for later
    wait = WebDriverWait(driver, 10)

    # Store the ID of the original window
    original_window = driver.current_window_handle

    # Check we don't have other windows open already
    assert len(driver.window_handles) == 1

    # Click the link which opens in a new window
    driver.find_element(By.LINK_TEXT, "new window").click()

    # Wait for the new window or tab
    wait.until(EC.number_of_windows_to_be(2))

    # Loop through until we find a new window handle
    for window_handle in driver.window_handles:
        if window_handle != original_window:
            driver.switch_to.window(window_handle)
            break

    # Wait for the new tab to finish loading content
    wait.until(EC.title_is("SeleniumHQ Browser Automation"))
  
//Store the ID of the original window
string originalWindow = driver.CurrentWindowHandle;

//Check we don't have other windows open already

    }
}
//Wait for the new tab to finish loading content

    #Store the ID of the original window

    #Check we don't have other windows open already
assert(driver.window_handles.length == 1, 'Expected one window')

    #Click the link which opens in a new window
driver.find_element(link: 'new window').click

    #Wait for the new window or tab
wait.until { driver.window_handles.length == 2 }

    #Loop through until we find a new window handle
driver.window_handles.each do |handle|
    if handle != original_window
        driver.switch_to.window handle
        break
    end
end

    #Wait for the new tab to finish loading content
wait.until { driver.title == 'Selenium documentation'}
  
//Store the ID of the original window
const originalWindow = await driver.getWindowHandle();

//Check we don't have other windows open already
assert((await driver.getAllWindowHandles()).length === 1);

//Click the link which opens in a new window
await driver.findElement(By.linkText('new window')).click();

//Wait for the new window or tab
await driver.wait(
    async () => (await driver.getAllWindowHandles()).length === 2,
    10000
  );

//Loop through until we find a new window handle
const windows = await driver.getAllWindowHandles();
windows.forEach(async handle => {
  if (handle !== originalWindow) {
    await driver.switchTo().window(handle);
  }
});

//Wait for the new tab to finish loading content
await driver.wait(until.titleIs('Selenium documentation'), 10000);
  
//Store the ID of the original window
val originalWindow = driver.getWindowHandle()

//Check we don't have other windows open already
assert(driver.getWindowHandles().size() === 1)

//Click the link which opens in a new window
driver.findElement(By.linkText("new window")).click()

//Wait for the new window or tab
wait.until(numberOfWindowsToBe(2))

//Loop through until we find a new window handle
for (windowHandle in driver.getWindowHandles()) {
    if (!originalWindow.contentEquals(windowHandle)) {
        driver.switchTo().window(windowHandle)
        break
    }
}

//Wait for the new tab to finish loading content
wait.until(titleIs("Selenium documentation"))

  

Criar nova janela (ou) nova guia e alternar

Cria uma nova janela (ou) guia e focará a nova janela ou guia na tela. Você não precisa mudar para trabalhar com a nova janela (ou) guia. Se você tiver mais de duas janelas (ou) guias abertas diferentes da nova janela, você pode percorrer as janelas ou guias que o WebDriver pode ver e mudar para aquela que não é a original.

Nota: este recurso funciona com Selenium 4 e versões posteriores.

// Opens a new tab and switches to new tab
driver.switchTo().newWindow(WindowType.TAB);

// Opens a new window and switches to new window
driver.switchTo().newWindow(WindowType.WINDOW);
  
    # Opens a new tab and switches to new tab
driver.switch_to.new_window('tab')

    # Opens a new window and switches to new window
driver.switch_to.new_window('window')
  
// Opens a new tab and switches to new tab
driver.SwitchTo().NewWindow(WindowType.Tab)

// Opens a new window and switches to new window
driver.SwitchTo().NewWindow(WindowType.Window)
  
    # Note: The new_window in ruby only opens a new tab (or) Window and will not switch automatically
    # The user has to switch to new tab (or) new window

    # Opens a new tab and switches to new tab
driver.manage.new_window(:tab)

    # Opens a new window and switches to new window
driver.manage.new_window(:window)
  
// Opens a new tab and switches to new tab
await driver.switchTo().newWindow('tab');

// Opens a new window and switches to new window
await driver.switchTo().newWindow('window');

  
// Opens a new tab and switches to new tab
driver.switchTo().newWindow(WindowType.TAB)

// Opens a new window and switches to new window
driver.switchTo().newWindow(WindowType.WINDOW)
  

Fechando uma janela ou guia

Quando você fechar uma janela ou guia e que não é a última janela ou guia aberta em seu navegador, você deve fechá-la e alternar de volta para a janela que você estava usando anteriormente. Supondo que você seguiu a amostra de código na seção anterior, você terá o identificador da janela anterior armazenado em uma variável. Junte isso e você obterá:

//Close the tab or window
driver.close();

//Switch back to the old tab or window
driver.switchTo().window(originalWindow);
  
    #Close the tab or window
driver.close()

    #Switch back to the old tab or window
driver.switch_to.window(original_window)
  
//Close the tab or window
driver.Close();

//Switch back to the old tab or window
driver.SwitchTo().Window(originalWindow);
  
    #Close the tab or window
driver.close

    #Switch back to the old tab or window
driver.switch_to.window original_window
  
//Close the tab or window
await driver.close();

//Switch back to the old tab or window
await driver.switchTo().window(originalWindow);
  
//Close the tab or window
driver.close()

//Switch back to the old tab or window
driver.switchTo().window(originalWindow)

  

Esquecer de voltar para outro gerenciador de janela após fechar uma janela deixará o WebDriver em execução na página agora fechada e acionara uma No Such Window Exception. Você deve trocar de volta para um identificador de janela válido para continuar a execução.

Sair do navegador no final de uma sessão

Quando você terminar a sessão do navegador, você deve chamar a função quit(), em vez de fechar:

driver.quit();
driver.quit()
driver.Quit();
driver.quit
await driver.quit();
driver.quit()
  • quit() irá:
    • Fechar todas as janelas e guias associadas a essa sessão do WebDriver
    • Fechar o processo do navegador
    • Fechar o processo do driver em segundo plano
    • Notificar o Selenium Grid de que o navegador não está mais em uso para que possa ser usado por outra sessão (se você estiver usando Selenium Grid)

A falha em encerrar deixará processos e portas extras em segundo plano rodando em sua máquina, o que pode causar problemas mais tarde.

Algumas estruturas de teste oferecem métodos e anotações em que você pode ligar para derrubar no final de um teste.

/**
 * Example using JUnit
 * https://junit.org/junit5/docs/current/api/org/junit/jupiter/api/AfterAll.html
 */
@AfterAll
public static void tearDown() {
    driver.quit();
}
  
    # unittest teardown
    # https://docs.python.org/3/library/unittest.html?highlight=teardown#unittest.TestCase.tearDown
def tearDown(self):
    self.driver.quit()
  
/*
    Example using Visual Studio's UnitTesting
    https://msdn.microsoft.com/en-us/library/microsoft.visualstudio.testtools.unittesting.aspx
*/
[TestCleanup]
public void TearDown()
{
    driver.Quit();
}
  
    # UnitTest Teardown
    # https://www.rubydoc.info/github/test-unit/test-unit/Test/Unit/TestCase
def teardown
    @driver.quit
end
  
/**
 * Example using Mocha
 * https://mochajs.org/#hooks
 */
after('Tear down', async function () {
  await driver.quit();
});
  
/**
 * Example using JUnit
 * https://junit.org/junit5/docs/current/api/org/junit/jupiter/api/AfterAll.html
 */
@AfterAll
fun tearDown() {
    driver.quit()
}
  

Se não estiver executando o WebDriver em um contexto de teste, você pode considerar o uso do try/finally que é oferecido pela maioria das linguagens para que uma exceção ainda limpe a sessão do WebDriver.

try {
    //WebDriver code here...
} finally {
    driver.quit();
}
  
try:
    #WebDriver code here...
finally:
    driver.quit()
  
try {
    //WebDriver code here...
} finally {
    driver.Quit();
}
  
begin
    #WebDriver code here...
ensure
    driver.quit
end
  
try {
    //WebDriver code here...
} finally {
    await driver.quit();
}
  
try {
    //WebDriver code here...
} finally {
    driver.quit()
}
  

O WebDriver do Python agora suporta o gerenciador de contexto python, que ao usar a palavra-chave with pode encerrar automaticamente o driver no fim da execução.

with webdriver.Firefox() as driver:
  # WebDriver code here...

# WebDriver will automatically quit after indentation

Gerenciamento de janelas

A resolução da tela pode impactar como seu aplicativo da web é renderizado, então WebDriver fornece mecanismos para mover e redimensionar a janela do navegador.

Coletar o tamanho da janela

Obtém o tamanho da janela do navegador em pixels.

//Access each dimension individually
int width = driver.manage().window().getSize().getWidth();
int height = driver.manage().window().getSize().getHeight();

//Or store the dimensions and query them later
Dimension size = driver.manage().window().getSize();
int width1 = size.getWidth();
int height1 = size.getHeight();
  
    # Access each dimension individually
width = driver.get_window_size().get("width")
height = driver.get_window_size().get("height")

    # Or store the dimensions and query them later
size = driver.get_window_size()
width1 = size.get("width")
height1 = size.get("height")
  
//Access each dimension individually
int width = driver.Manage().Window.Size.Width;
int height = driver.Manage().Window.Size.Height;

//Or store the dimensions and query them later
System.Drawing.Size size = driver.Manage().Window.Size;
int width1 = size.Width;
int height1 = size.Height;
  
    # Access each dimension individually
width = driver.manage.window.size.width
height = driver.manage.window.size.height

    # Or store the dimensions and query them later
size = driver.manage.window.size
width1 = size.width
height1 = size.height
  
// Access each dimension individually
const { width, height } = await driver.manage().window().getRect();

// Or store the dimensions and query them later
const rect = await driver.manage().window().getRect();
const width1 = rect.width;
const height1 = rect.height;
  
//Access each dimension individually
val width = driver.manage().window().size.width
val height = driver.manage().window().size.height

//Or store the dimensions and query them later
val size = driver.manage().window().size
val width1 = size.width
val height1 = size.height
  

Definir o tamanho da janela

Restaura a janela e define o tamanho da janela.

driver.manage().window().setSize(new Dimension(1024, 768));
driver.set_window_size(1024, 768)
driver.Manage().Window.Size = new Size(1024, 768);
driver.manage.window.resize_to(1024,768)
await driver.manage().window().setRect({ width: 1024, height: 768 });
driver.manage().window().size = Dimension(1024, 768)

Coletar posição da janela

Busca as coordenadas da coordenada superior esquerda da janela do navegador.

// Access each dimension individually
int x = driver.manage().window().getPosition().getX();
int y = driver.manage().window().getPosition().getY();

// Or store the dimensions and query them later
Point position = driver.manage().window().getPosition();
int x1 = position.getX();
int y1 = position.getY();
  
    # Access each dimension individually
x = driver.get_window_position().get('x')
y = driver.get_window_position().get('y')

    # Or store the dimensions and query them later
position = driver.get_window_position()
x1 = position.get('x')
y1 = position.get('y')
  
//Access each dimension individually
int x = driver.Manage().Window.Position.X;
int y = driver.Manage().Window.Position.Y;

//Or store the dimensions and query them later
Point position = driver.Manage().Window.Position;
int x1 = position.X;
int y1 = position.Y;
  
    #Access each dimension individually
x = driver.manage.window.position.x
y = driver.manage.window.position.y

    # Or store the dimensions and query them later
rect  = driver.manage.window.rect
x1 = rect.x
y1 = rect.y
  
// Access each dimension individually
const { x, y } = await driver.manage().window().getRect();

// Or store the dimensions and query them later
const rect = await driver.manage().window().getRect();
const x1 = rect.x;
const y1 = rect.y;
  
// Access each dimension individually
val x = driver.manage().window().position.x
val y = driver.manage().window().position.y

// Or store the dimensions and query them later
val position = driver.manage().window().position
val x1 = position.x
val y1 = position.y

  

Definir posição da janela

Move a janela para a posição escolhida.

// Move the window to the top left of the primary monitor
driver.manage().window().setPosition(new Point(0, 0));
  
    # Move the window to the top left of the primary monitor
driver.set_window_position(0, 0)
  
// Move the window to the top left of the primary monitor
driver.Manage().Window.Position = new Point(0, 0);
  
driver.manage.window.move_to(0,0)
  
// Move the window to the top left of the primary monitor
await driver.manage().window().setRect({ x: 0, y: 0 });
  
// Move the window to the top left of the primary monitor
driver.manage().window().position = Point(0,0)
    

Maximizar janela

Aumenta a janela. Para a maioria dos sistemas operacionais, a janela irá preencher a tela, sem bloquear os próprios menus do sistema operacional e barras de ferramentas.

driver.manage().window().maximize();
driver.maximize_window()
driver.Manage().Window.Maximize();
driver.manage.window.maximize
await driver.manage().window().maximize();
driver.manage().window().maximize()

Minimizar janela

Minimiza a janela do contexto de navegação atual. O comportamento exato deste comando é específico para gerenciadores de janela individuais.

Minimizar Janela normalmente oculta a janela na bandeja do sistema.

Nota: este recurso funciona com Selenium 4 e versões posteriores.

driver.manage().window().minimize();
driver.minimize_window()
driver.Manage().Window.Minimize();
driver.manage.window.minimize
await driver.manage().window().minimize();
driver.manage().window().minimize()

Janela em tamanho cheio

Preenche a tela inteira, semelhante a pressionar F11 na maioria dos navegadores.

driver.manage().window().fullscreen();
driver.fullscreen_window()
driver.Manage().Window.FullScreen();
driver.manage.window.full_screen
await driver.manage().window().fullscreen();
driver.manage().window().fullscreen()

TakeScreenshot

6.6 - Virtual Authenticator

Uma representação do modelo Web Authenticator.

Aplicações web podem habilitar um mecanismo de autenticação baseado em chaves públicas conhecido como Web Authentication para autenticar usuários sem usar uma senha. Web Authentication define APIs que permitem ao usuário criar uma credencial e registra-la com um autenticador. Um autenticador pode ser um dispositivo ou um software que guarde as chaves públicas do usuário e as acesse caso seja pedido.

Como o nome sugere, Virtual Authenticator emula esses autenticadores para testes.

Virtual Authenticator Options

Um Autenticador Virtual tem uma série de propriedades. Essas propriedades são mapeadas como VirtualAuthenticatorOptions nos bindings do Selenium.

    new PKCS8EncodedKeySpec(Base64.getUrlDecoder().decode(base64EncodedEC256PK));

  public WebDriver driver;

  @BeforeEach
  public void setup() {
    driver = new ChromeDriver();
            // Create virtual authenticator options
            VirtualAuthenticatorOptions options = new VirtualAuthenticatorOptions()
                .SetIsUserVerified(true)
                .SetHasUserVerification(true)
                .SetIsUserConsenting(true)
                .SetTransport(VirtualAuthenticatorOptions.Transport.USB)
                .SetProtocol(VirtualAuthenticatorOptions.Protocol.U2F)
                .SetHasResidentKey(false);
    it('Virtual options', async function () {
      options = new VirtualAuthenticatorOptions();
      options.setIsUserVerified(true);
      options.setHasUserVerification(true);
      options.setIsUserConsenting(true);
      options.setTransport(Transport['USB']);
      options.setProtocol(Protocol['U2F']);

Add Virtual Authenticator

Cria um novo autenticador virtual com as propriedades fornecidas.


  @Test
  public void testVirtualOptions() {
    // Create virtual authenticator options
    VirtualAuthenticatorOptions options = new VirtualAuthenticatorOptions()
      .setIsUserVerified(true)
            // Create virtual authenticator options
            VirtualAuthenticatorOptions options = new VirtualAuthenticatorOptions()
                .SetProtocol(VirtualAuthenticatorOptions.Protocol.U2F)
                .SetHasResidentKey(false);

            // Register a virtual authenticator
            ((WebDriver)driver).AddVirtualAuthenticator(options);

            List<Credential> credentialList = ((WebDriver)driver).GetCredentials();
            options.setProtocol(Protocol['U2F']);
            options.setHasResidentKey(false);

            // Register a virtual authenticator
            await driver.addVirtualAuthenticator(options);

Remove Virtual Authenticator

            VirtualAuthenticatorOptions options = new VirtualAuthenticatorOptions()
                .SetProtocol(VirtualAuthenticatorOptions.Protocol.U2F)
                .SetHasResidentKey(false);

            String virtualAuthenticatorId = ((WebDriver)driver).AddVirtualAuthenticator(options);

            ((WebDriver)driver).RemoveVirtualAuthenticator(virtualAuthenticatorId);
            await driver.addVirtualAuthenticator(options);
            await driver.removeVirtualAuthenticator();

Create Resident Credential

    PKCS8EncodedKeySpec privateKey =
      new PKCS8EncodedKeySpec(Base64.getUrlDecoder().decode(base64EncodedEC256PK));

    byte[] credentialId = {1, 2, 3, 4};
    byte[] userHandle = {1};
            VirtualAuthenticatorOptions options = new VirtualAuthenticatorOptions()
                .SetProtocol(VirtualAuthenticatorOptions.Protocol.U2F)
                .SetHasResidentKey(false);

            ((WebDriver)driver).AddVirtualAuthenticator(options);

            byte[] credentialId = { 1, 2, 3, 4 };

            Credential nonResidentCredential = Credential.CreateNonResidentCredential(
              credentialId, "localhost", base64EncodedEC256PK, 0);

            ((WebDriver)driver).AddCredential(nonResidentCredential);

            VirtualAuthenticatorOptions options = new VirtualAuthenticatorOptions()
                .SetProtocol(Protocol.CTAP2)
                .SetHasResidentKey(true)
                .SetHasUserVerification(true)
                .SetIsUserVerified(true);

            ((WebDriver)driver).AddVirtualAuthenticator(options);

            byte[] credentialId = { 1, 2, 3, 4 };
            byte[] userHandle = { 1 };

  }
            VirtualAuthenticatorOptions options = new VirtualAuthenticatorOptions()
                .SetIsUserVerified(true);

7 - Actions API

A low-level interface for providing virtualized device input actions to the web browser.

In addition to the high-level element interactions, the Actions API provides granular control over exactly what designated input devices can do. Selenium provides an interface for 3 kinds of input sources: a key input for keyboard devices, a pointer input for a mouse, pen or touch devices, and wheel inputs for scroll wheel devices (introduced in Selenium 4.2). Selenium allows you to construct individual action commands assigned to specific inputs and chain them together and call the associated perform method to execute them all at once.

Action Builder

In the move from the legacy JSON Wire Protocol to the new W3C WebDriver Protocol, the low level building blocks of actions became especially detailed. It is extremely powerful, but each input device has a number of ways to use it and if you need to manage more than one device, you are responsible for ensuring proper synchronization between them.

Thankfully, you likely do not need to learn how to use the low level commands directly, since almost everything you might want to do has been given a convenience method that combines the lower level commands for you. These are all documented in keyboard, mouse, pen, and wheel pages.

Pause

Pointer movements and Wheel scrolling allow the user to set a duration for the action, but sometimes you just need to wait a beat between actions for things to work correctly.

        WebElement clickable = driver.findElement(By.id("clickable"));
        new Actions(driver)
                .moveToElement(clickable)
                .pause(Duration.ofSeconds(1))
                .clickAndHold()
                .pause(Duration.ofSeconds(1))
                .sendKeys("abc")
                .perform();
    clickable = driver.find_element(By.ID, "clickable")
    ActionChains(driver)\
        .move_to_element(clickable)\
        .pause(1)\
        .click_and_hold()\
        .pause(1)\
        .send_keys("abc")\
        .perform()

Selenium v4.2

            IWebElement clickable = driver.FindElement(By.Id("clickable"));
            new Actions(driver)
                .MoveToElement(clickable)
                .Pause(TimeSpan.FromSeconds(1))
                .ClickAndHold()
                .Pause(TimeSpan.FromSeconds(1))
                .SendKeys("abc")
                .Perform();

Selenium v4.2

    clickable = driver.find_element(id: 'clickable')
    driver.action
          .move_to(clickable)
          .pause(duration: 1)
          .click_and_hold
          .pause(duration: 1)
          .send_keys('abc')
          .perform
      const clickable = await driver.findElement(By.id('clickable'))
      await driver.actions()
        .move({ origin: clickable })
        .pause(1000)
        .press()
        .pause(1000)
        .sendKeys('abc')
        .perform()
        val clickable = driver.findElement(By.id("clickable"))
        Actions(driver)
            .moveToElement(clickable)
            .pause(Duration.ofSeconds(1))
            .clickAndHold()
            .pause(Duration.ofSeconds(1))
            .sendKeys("abc")
            .perform() 

Release All Actions

An important thing to note is that the driver remembers the state of all the input items throughout a session. Even if you create a new instance of an actions class, the depressed keys and the location of the pointer will be in whatever state a previously performed action left them.

There is a special method to release all currently depressed keys and pointer buttons. This method is implemented differently in each of the languages because it does not get executed with the perform method.

        ((RemoteWebDriver) driver).resetInputState();
    ActionBuilder(driver).clear_actions()
            ((WebDriver)driver).ResetInputState();
    driver.action.release_actions
      await driver.actions().clear()
        (driver as RemoteWebDriver).resetInputState()

7.1 - Keyboard actions

A representation of any key input device for interacting with a web page.

There are only 2 actions that can be accomplished with a keyboard: pressing down on a key, and releasing a pressed key. In addition to supporting ASCII characters, each keyboard key has a representation that can be pressed or released in designated sequences.

Keys

In addition to the keys represented by regular unicode, unicode values have been assigned to other keyboard keys for use with Selenium. Each language has its own way to reference these keys; the full list can be found here.

        new Actions(driver)
                .keyDown(Keys.SHIFT)
                .sendKeys("a")
                .keyUp(Keys.SHIFT)

Send keys

This is a convenience method in the Actions API that combines keyDown and keyUp commands in one action. Executing this command differs slightly from using the element method, but primarily this gets used when needing to type multiple characters in the middle of other actions.

Active Element

        new Actions(driver)
                .sendKeys("abc")
                .perform();
    ActionChains(driver)\
        .send_keys("abc")\
        .perform()

            new Actions(driver)
                .SendKeys("abc")
    driver.action
          .send_keys('abc')
          .perform
      const textField = driver.findElement(By.id('textInput'))
      await textField.click()
        Actions(driver)
                .sendKeys("abc")
                .perform()

Designated Element

        new Actions(driver)
                .sendKeys(textField, "Selenium!")
                .perform();

Copy and Paste

Here’s an example of using all of the above methods to conduct a copy / paste action. Note that the key to use for this operation will be different depending on if it is a Mac OS or not. This code will end up with the text: SeleniumSelenium!

        Keys cmdCtrl = Platform.getCurrent().is(Platform.MAC) ? Keys.COMMAND : Keys.CONTROL;

        WebElement textField = driver.findElement(By.id("textInput"));
        new Actions(driver)

                .keyUp(cmdCtrl)
                .perform();

7.2 - Mouse actions

A representation of any pointer device for interacting with a web page.

There are only 3 actions that can be accomplished with a mouse: pressing down on a button, releasing a pressed button, and moving the mouse. Selenium provides convenience methods that combine these actions in the most common ways.

Click and hold

This method combines moving the mouse to the center of an element with pressing the left mouse button. This is useful for focusing a specific element:

        WebElement clickable = driver.findElement(By.id("clickable"));
        new Actions(driver)
                .clickAndHold(clickable)
                .perform();
    clickable = driver.find_element(By.ID, "clickable")
    ActionChains(driver)\
        .click_and_hold(clickable)\
        .perform()
            IWebElement clickable = driver.FindElement(By.Id("clickable"));
            new Actions(driver)
                .ClickAndHold(clickable)
                .Perform();
    clickable = driver.find_element(id: 'clickable')
    driver.action
          .click_and_hold(clickable)
          .perform
      let clickable = driver.findElement(By.id("clickable"));
      const actions = driver.actions({async: true});
      await actions.move({origin: clickable}).press().perform();
        val clickable = driver.findElement(By.id("clickable"))
        Actions(driver)
                .clickAndHold(clickable)
                .perform()

Click and release

This method combines moving to the center of an element with pressing and releasing the left mouse button. This is otherwise known as “clicking”:

        WebElement clickable = driver.findElement(By.id("click"));
        new Actions(driver)
                .click(clickable)
                .perform();
    clickable = driver.find_element(By.ID, "click")
    ActionChains(driver)\
        .click(clickable)\
        .perform()
            IWebElement clickable = driver.FindElement(By.Id("click"));
            new Actions(driver)
                .Click(clickable)
                .Perform();
    clickable = driver.find_element(id: 'click')
    driver.action
          .click(clickable)
          .perform
      let click = driver.findElement(By.id("click"));
      const actions = driver.actions({async: true});
      await actions.move({origin: click}).click().perform();
        val clickable = driver.findElement(By.id("click"))
        Actions(driver)
                .click(clickable)
                .perform()

Alternate Button Clicks

There are a total of 5 defined buttons for a Mouse:

  • 0 — Left Button (the default)
  • 1 — Middle Button (currently unsupported)
  • 2 — Right Button
  • 3 — X1 (Back) Button
  • 4 — X2 (Forward) Button

Context Click

This method combines moving to the center of an element with pressing and releasing the right mouse button (button 2). This is otherwise known as “right-clicking”:

        WebElement clickable = driver.findElement(By.id("clickable"));
        new Actions(driver)
                .contextClick(clickable)
                .perform();
    clickable = driver.find_element(By.ID, "clickable")
    ActionChains(driver)\
        .context_click(clickable)\
        .perform()
            IWebElement clickable = driver.FindElement(By.Id("clickable"));
            new Actions(driver)
                .ContextClick(clickable)
                .Perform();
      clickable = driver.find_element(id: 'clickable')
      driver.action
            .context_click(clickable)
            .perform
      const clickable = driver.findElement(By.id("clickable"));
      const actions = driver.actions({async: true});
      await actions.contextClick(clickable).perform();
        val clickable = driver.findElement(By.id("clickable"))
        Actions(driver)
                .contextClick(clickable)
                .perform()

Back Click

There is no convenience method for this, it is just pressing and releasing mouse button 3

        PointerInput mouse = new PointerInput(PointerInput.Kind.MOUSE, "default mouse");

        Sequence actions = new Sequence(mouse, 0)
                .addAction(mouse.createPointerDown(PointerInput.MouseButton.BACK.asArg()))
                .addAction(mouse.createPointerUp(PointerInput.MouseButton.BACK.asArg()));

        val actions = Sequence(mouse, 0)
                .addAction(mouse.createPointerDown(PointerInput.MouseButton.BACK.asArg()))
                .addAction(mouse.createPointerUp(PointerInput.MouseButton.BACK.asArg()))

        (driver as RemoteWebDriver).perform(Collections.singletonList(actions))

Forward Click

        PointerInput mouse = new PointerInput(PointerInput.Kind.MOUSE, "default mouse");

        Sequence actions = new Sequence(mouse, 0)
                .addAction(mouse.createPointerDown(PointerInput.MouseButton.FORWARD.asArg()))
                .addAction(mouse.createPointerUp(PointerInput.MouseButton.FORWARD.asArg()));

                .addAction(mouse.createPointerUp(PointerInput.MouseButton.FORWARD.asArg()))

        (driver as RemoteWebDriver).perform(Collections.singletonList(actions))

Double click

This method combines moving to the center of an element with pressing and releasing the left mouse button twice.

        WebElement clickable = driver.findElement(By.id("clickable"));
        new Actions(driver)
                .doubleClick(clickable)
                .perform();
    clickable = driver.find_element(By.ID, "clickable")
    ActionChains(driver)\
        .double_click(clickable)\
        .perform()
            IWebElement clickable = driver.FindElement(By.Id("clickable"));
            new Actions(driver)
                .DoubleClick(clickable)
                .Perform();
    clickable = driver.find_element(id: 'clickable')
    driver.action
          .double_click(clickable)
          .perform
      const clickable = driver.findElement(By.id("clickable"));
      const actions = driver.actions({async: true});
      await actions.doubleClick(clickable).perform();

        Actions(driver)
                .doubleClick(clickable)
                .perform()

Move to element

This method moves the mouse to the in-view center point of the element. This is otherwise known as “hovering.” Note that the element must be in the viewport or else the command will error.

        WebElement hoverable = driver.findElement(By.id("hover"));
        new Actions(driver)
                .moveToElement(hoverable)
                .perform();
    hoverable = driver.find_element(By.ID, "hover")
    ActionChains(driver)\
        .move_to_element(hoverable)\
        .perform()
            IWebElement hoverable = driver.FindElement(By.Id("hover"));
            new Actions(driver)
                .MoveToElement(hoverable)
                .Perform();
    hoverable = driver.find_element(id: 'hover')
    driver.action
          .move_to(hoverable)
          .perform
      const hoverable = driver.findElement(By.id("hover"));
      const actions = driver.actions({async: true});
      await actions.move({origin: hoverable}).perform();
        val hoverable = driver.findElement(By.id("hover"))
        Actions(driver)
                .moveToElement(hoverable)
                .perform()

Move by offset

These methods first move the mouse to the designated origin and then by the number of pixels in the provided offset. Note that the position of the mouse must be in the viewport or else the command will error.

Offset from Element

This method moves the mouse to the in-view center point of the element, then moves by the provided offset.

        WebElement tracker = driver.findElement(By.id("mouse-tracker"));
        new Actions(driver)
                .moveToElement(tracker, 8, 0)
                .perform();
    mouse_tracker = driver.find_element(By.ID, "mouse-tracker")
    ActionChains(driver)\
        .move_to_element_with_offset(mouse_tracker, 8, 0)\
        .perform()
            IWebElement tracker = driver.FindElement(By.Id("mouse-tracker"));
            new Actions(driver)
                .MoveToElement(tracker, 8, 0)
                .Perform();
      mouse_tracker = driver.find_element(id: 'mouse-tracker')
      driver.action
            .move_to(mouse_tracker, 8, 11)
            .perform
        val tracker = driver.findElement(By.id("mouse-tracker"))
        Actions(driver)
                .moveToElement(tracker, 8, 0)
                .perform()

Offset from Viewport

This method moves the mouse from the upper left corner of the current viewport by the provided offset.

        PointerInput mouse = new PointerInput(PointerInput.Kind.MOUSE, "default mouse");

        Sequence actions = new Sequence(mouse, 0)
                .addAction(mouse.createPointerMove(Duration.ZERO, PointerInput.Origin.viewport(), 8, 12));

        ((RemoteWebDriver) driver).perform(Collections.singletonList(actions));
    action = ActionBuilder(driver)
    action.pointer_action.move_to_location(8, 0)
    action.perform()
            ActionBuilder actionBuilder = new ActionBuilder();
            PointerInputDevice mouse = new PointerInputDevice(PointerKind.Mouse, "default mouse");
            actionBuilder.AddAction(mouse.CreatePointerMove(CoordinateOrigin.Viewport,
                8, 0, TimeSpan.Zero));
            ((IActionExecutor)driver).PerformActions(actionBuilder.ToActionSequenceList());
      driver.action
            .move_to_location(8, 12)
            .perform
      const actions = driver.actions({async: true});
      await actions.move({x: 8, y: 0}).perform();
        val mouse = PointerInput(PointerInput.Kind.MOUSE, "default mouse")

        val actions = Sequence(mouse, 0)
                .addAction(mouse.createPointerMove(Duration.ZERO, PointerInput.Origin.viewport(), 8, 12))

        (driver as RemoteWebDriver).perform(Collections.singletonList(actions))

Offset from Current Pointer Location

This method moves the mouse from its current position by the offset provided by the user. If the mouse has not previously been moved, the position will be in the upper left corner of the viewport. Note that the pointer position does not change when the page is scrolled.

Note that the first argument X specifies to move right when positive, while the second argument Y specifies to move down when positive. So moveByOffset(30, -10) moves right 30 and up 10 from the current mouse position.

        new Actions(driver)
                .moveByOffset(13, 15)
                .perform();
    ActionChains(driver)\
        .move_by_offset( 13, 15)\
        .perform()
            new Actions(driver)
                .MoveByOffset(13, 15)
                .Perform();
      driver.action
            .move_by(13, 15)
            .perform
      await actions.move({x: 13, y: 15, origin: Origin.POINTER}).perform()
        Actions(driver)
                .moveByOffset(13, 15)
                .perform()

Drag and Drop on Element

This method firstly performs a click-and-hold on the source element, moves to the location of the target element and then releases the mouse.

        WebElement draggable = driver.findElement(By.id("draggable"));
        WebElement droppable = driver.findElement(By.id("droppable"));
        new Actions(driver)
                .dragAndDrop(draggable, droppable)
                .perform();
    draggable = driver.find_element(By.ID, "draggable")
    droppable = driver.find_element(By.ID, "droppable")
    ActionChains(driver)\
        .drag_and_drop(draggable, droppable)\
        .perform()
            IWebElement draggable = driver.FindElement(By.Id("draggable"));
            IWebElement droppable = driver.FindElement(By.Id("droppable"));
            new Actions(driver)
                .DragAndDrop(draggable, droppable)
                .Perform();
    draggable = driver.find_element(id: 'draggable')
    droppable = driver.find_element(id: 'droppable')
    driver.action
          .drag_and_drop(draggable, droppable)
          .perform
      const draggable = driver.findElement(By.id("draggable"));
      const droppable = await driver.findElement(By.id("droppable"));
      const actions = driver.actions({async: true});
      await actions.dragAndDrop(draggable, droppable).perform();
        val draggable = driver.findElement(By.id("draggable"))
        val droppable = driver.findElement(By.id("droppable"))
        Actions(driver)
                .dragAndDrop(draggable, droppable)
                .perform()

Drag and Drop by Offset

This method firstly performs a click-and-hold on the source element, moves to the given offset and then releases the mouse.

        WebElement draggable = driver.findElement(By.id("draggable"));
        Rectangle start = draggable.getRect();
        Rectangle finish = driver.findElement(By.id("droppable")).getRect();
        new Actions(driver)
                .dragAndDropBy(draggable, finish.getX() - start.getX(), finish.getY() - start.getY())
                .perform();
    draggable = driver.find_element(By.ID, "draggable")
    start = draggable.location
    finish = driver.find_element(By.ID, "droppable").location
    ActionChains(driver)\
        .drag_and_drop_by_offset(draggable, finish['x'] - start['x'], finish['y'] - start['y'])\
        .perform()
            IWebElement draggable = driver.FindElement(By.Id("draggable"));
            Point start = draggable.Location;
            Point finish = driver.FindElement(By.Id("droppable")).Location;
            new Actions(driver)
                .DragAndDropToOffset(draggable, finish.X - start.X, finish.Y - start.Y)
                .Perform();
    draggable = driver.find_element(id: 'draggable')
    start = draggable.rect

7.3 - Pen actions

A representation of a pen stylus kind of pointer input for interacting with a web page.

Chromium Only

A Pen is a type of pointer input that has most of the same behavior as a mouse, but can also have event properties unique to a stylus. Additionally, while a mouse has 5 buttons, a pen has 3 equivalent button states:

  • 0 — Touch Contact (the default; equivalent to a left click)
  • 2 — Barrel Button (equivalent to a right click)
  • 5 — Eraser Button (currently unsupported by drivers)

7.4 - Scroll wheel actions

A representation of a scroll wheel input device for interacting with a web page.

Selenium v4.2

Chromium Only

There are 5 scenarios for scrolling on a page.

Scroll to element

This is the most common scenario. Unlike traditional click and send keys methods, the actions class does not automatically scroll the target element into view, so this method will need to be used if elements are not already inside the viewport.

This method takes a web element as the sole argument.

Regardless of whether the element is above or below the current viewscreen, the viewport will be scrolled so the bottom of the element is at the bottom of the screen.

        WebElement iframe = driver.findElement(By.tagName("iframe"));
        new Actions(driver)
                .scrollToElement(iframe)
                .perform();
    iframe = driver.find_element(By.TAG_NAME, "iframe")
    ActionChains(driver)\
        .scroll_to_element(iframe)\
        .perform()
            IWebElement iframe = driver.FindElement(By.TagName("iframe"));
            new Actions(driver)
                .ScrollToElement(iframe)
                .Perform();
    iframe = driver.find_element(tag_name: 'iframe')
    driver.action
          .scroll_to(iframe)
          .perform
      const iframe = await driver.findElement(By.css("iframe"))

      await driver.actions()
        .scroll(0, 0, 0, 0, iframe)
        .perform()
        val iframe = driver.findElement(By.tagName("iframe"))
        Actions(driver)
                .scrollToElement(iframe)
                .perform()

Scroll by given amount

This is the second most common scenario for scrolling. Pass in an delta x and a delta y value for how much to scroll in the right and down directions. Negative values represent left and up, respectively.

        WebElement footer = driver.findElement(By.tagName("footer"));
        int deltaY = footer.getRect().y;
        new Actions(driver)
                .scrollByAmount(0, deltaY)
                .perform();
    footer = driver.find_element(By.TAG_NAME, "footer")
    delta_y = footer.rect['y']
    ActionChains(driver)\
        .scroll_by_amount(0, delta_y)\
        .perform()
            IWebElement footer = driver.FindElement(By.TagName("footer"));
            int deltaY = footer.Location.Y;
            new Actions(driver)
                .ScrollByAmount(0, deltaY)
                .Perform();
    footer = driver.find_element(tag_name: 'footer')
    delta_y = footer.rect.y
    driver.action
          .scroll_by(0, delta_y)
          .perform
      const footer = await driver.findElement(By.css("footer"))
      const deltaY = (await footer.getRect()).y

      await driver.actions()
        .scroll(0, 0, 0, deltaY)
        .perform()
        val footer = driver.findElement(By.tagName("footer"))
        val deltaY = footer.getRect().y
        Actions(driver)
                .scrollByAmount(0, deltaY)
                .perform()

Scroll from an element by a given amount

This scenario is effectively a combination of the above two methods.

To execute this use the “Scroll From” method, which takes 3 arguments. The first represents the origination point, which we designate as the element, and the second two are the delta x and delta y values.

If the element is out of the viewport, it will be scrolled to the bottom of the screen, then the page will be scrolled by the provided delta x and delta y values.

        WebElement iframe = driver.findElement(By.tagName("iframe"));
        WheelInput.ScrollOrigin scrollOrigin = WheelInput.ScrollOrigin.fromElement(iframe);
        new Actions(driver)
                .scrollFromOrigin(scrollOrigin, 0, 200)
                .perform();
    iframe = driver.find_element(By.TAG_NAME, "iframe")
    scroll_origin = ScrollOrigin.from_element(iframe)
    ActionChains(driver)\
        .scroll_from_origin(scroll_origin, 0, 200)\
        .perform()
            IWebElement iframe = driver.FindElement(By.TagName("iframe"));
            WheelInputDevice.ScrollOrigin scrollOrigin = new WheelInputDevice.ScrollOrigin
            {
                Element = iframe
            };
            new Actions(driver)
                .ScrollFromOrigin(scrollOrigin, 0, 200)
                .Perform();
    iframe = driver.find_element(tag_name: 'iframe')
    scroll_origin = Selenium::WebDriver::WheelActions::ScrollOrigin.element(iframe)
    driver.action
          .scroll_from(scroll_origin, 0, 200)
          .perform
      const iframe = await driver.findElement(By.css("iframe"))

      await driver.actions()
        .scroll(0, 0, 0, 200, iframe)
        .perform()
        val iframe = driver.findElement(By.tagName("iframe"))
        val scrollOrigin = WheelInput.ScrollOrigin.fromElement(iframe)
        Actions(driver)
                .scrollFromOrigin(scrollOrigin, 0, 200)
                .perform()

Scroll from an element with an offset

This scenario is used when you need to scroll only a portion of the screen, and it is outside the viewport. Or is inside the viewport and the portion of the screen that must be scrolled is a known offset away from a specific element.

This uses the “Scroll From” method again, and in addition to specifying the element, an offset is specified to indicate the origin point of the scroll. The offset is calculated from the center of the provided element.

If the element is out of the viewport, it first will be scrolled to the bottom of the screen, then the origin of the scroll will be determined by adding the offset to the coordinates of the center of the element, and finally the page will be scrolled by the provided delta x and delta y values.

Note that if the offset from the center of the element falls outside of the viewport, it will result in an exception.

        WebElement footer = driver.findElement(By.tagName("footer"));
        WheelInput.ScrollOrigin scrollOrigin = WheelInput.ScrollOrigin.fromElement(footer, 0, -50);
        new Actions(driver)
                .scrollFromOrigin(scrollOrigin,0, 200)
                .perform();
    footer = driver.find_element(By.TAG_NAME, "footer")
    scroll_origin = ScrollOrigin.from_element(footer, 0, -50)
    ActionChains(driver)\
        .scroll_from_origin(scroll_origin, 0, 200)\
        .perform()
            IWebElement footer = driver.FindElement(By.TagName("footer"));
            var scrollOrigin = new WheelInputDevice.ScrollOrigin
            {
                Element = footer,
                XOffset = 0,
                YOffset = -50
            };
            new Actions(driver)
                .ScrollFromOrigin(scrollOrigin, 0, 200)
                .Perform();
    footer = driver.find_element(tag_name: 'footer')
    scroll_origin = Selenium::WebDriver::WheelActions::ScrollOrigin.element(footer, 0, -50)
    driver.action
          .scroll_from(scroll_origin, 0, 200)
          .perform
      const footer = await driver.findElement(By.css("footer"))

      await driver.actions()
        .scroll(0, -50, 0, 200, footer)
        .perform()
        val footer = driver.findElement(By.tagName("footer"))
        val scrollOrigin = WheelInput.ScrollOrigin.fromElement(footer, 0, -50)
        Actions(driver)
                .scrollFromOrigin(scrollOrigin,0, 200)
                .perform()

Scroll from a offset of origin (element) by given amount

The final scenario is used when you need to scroll only a portion of the screen, and it is already inside the viewport.

This uses the “Scroll From” method again, but the viewport is designated instead of an element. An offset is specified from the upper left corner of the current viewport. After the origin point is determined, the page will be scrolled by the provided delta x and delta y values.

Note that if the offset from the upper left corner of the viewport falls outside of the screen, it will result in an exception.

        WheelInput.ScrollOrigin scrollOrigin = WheelInput.ScrollOrigin.fromViewport(10, 10);
        new Actions(driver)
                .scrollFromOrigin(scrollOrigin, 0, 200)
                .perform();
    scroll_origin = ScrollOrigin.from_viewport(10, 10)

    ActionChains(driver)\
        .scroll_from_origin(scroll_origin, 0, 200)\
        .perform()
            var scrollOrigin = new WheelInputDevice.ScrollOrigin
            {
                Viewport = true,
                XOffset = 10,
                YOffset = 10
            };
            new Actions(driver)
                .ScrollFromOrigin(scrollOrigin, 0, 200)
                .Perform();
    scroll_origin = Selenium::WebDriver::WheelActions::ScrollOrigin.viewport(10, 10)
    driver.action
          .scroll_from(scroll_origin, 0, 200)
          .perform
      await driver.actions()
        .scroll(10, 10, 0, 200)
        .perform()
        val scrollOrigin = WheelInput.ScrollOrigin.fromViewport(10, 10)
        Actions(driver)
                .scrollFromOrigin(scrollOrigin, 0, 200)
                .perform()

8 - BiDirectional Functionality

Page being translated from English to Portuguese. Do you speak Portuguese? Help us to translate it by sending us pull requests!

Selenium is working with browser vendors to create the WebDriver BiDirectional Protocol as a means to provide a stable, cross-browser API that uses the bidirectional functionality useful for both browser automation generally and testing specifically. Before now, users seeking this functionality have had to rely on with all of its frustrations and limitations.

The traditional WebDriver model of strict request/response commands will be supplemented with the ability to stream events from the user agent to the controlling software via WebSockets, better matching the evented nature of the browser DOM.

As it is not a good idea to tie your tests to a specific version of any browser, the Selenium project recommends using WebDriver BiDi wherever possible.

However, until the specification is complete there are many useful things that CDP (Chrome DevTools Protocol) offers. To help keep your tests independent and portable, Selenium offers some useful helper classes as well. At the moment, they use the CDP, but soon it could be done using WebDriver BiDi.

8.1 - Chrome DevTools

Apesar do Selenium 4 providenciar acesso direto ao Protocolo Chrome DevTools (CDP), é altamente recomendável que você use o WebDriver Bidi APIs ao invés do acesso direto.

Muitos navegadores fornecem o “DevTools”, um conjunto de ferramentas integradas ao navegador, que desenvolvedores podem usar para depurar web apps analisar o desempenho de suas páginas. O DevTools do Google Chrome faz o uso de um protocolo chamado Protocolo Chrome DevTools (abreviado como “CDP”). Como o nome sugere, ele não foi projetado para testes, ou tem uma API estável, portanto, sua funcionalidade depende muito da versão do navegador de internet.

WebDriver Bidi é a próxima geração do protocolo W3C WebDriver e visa fornecer uma API estável implementado por todos os navegadores, mas ele ainda não está completo. Até que seja, o Selenium fornece acesso ao CDP para os navegadores que o implementam (como Google Chrome ou Microsoft Edge e Firefox), permitindo que você aprimore seus testes de maneiras interessantes. Alguns exemplos do que você pode fazer com ele são dadas abaixo.

Emular Geo Localização

Alguns aplicativos têm recursos e funcionalidades diferentes em diferentes locations. Automatizar esses tipos de aplicativos é complicado porque é difícil emular as geolocalizações no navegador usando o Selenium. Mas com a ajuda do Devtools, podemos facilmente as emular. O trecho do código abaixo demonstra isso.

ChromeDriver driver = new ChromeDriver();
DevTools devTools = driver.getDevTools();
devTools.createSession();
devTools.send(Emulation.setGeolocationOverride(Optional.of(52.5043),
                                               Optional.of(13.4501),
                                               Optional.of(1)));
driver.get("https://my-location.org/");

Modo de Dispositivo Override

Usando a integração do Selenium com o CDP, pode-se substituir o modo do dispositivo atual e simular um novo modo. Width(largura), Height(altura), mobile(mobilidade) e deviceScaleFactor são parâmetros obrigatórios. Parâmetros opcionais incluem scale(escala), screenWidth(largura da tela), screenHeight(altura da tela), positionX, positionY, dontSetVisible(não setar como visível), screenOrientation(orientação da tela), viewport e displayFeature.

8.2 - API BiDirecional (CDP implementation)

A seguinte lista de APIs crescerá à medida que o projeto Selenium se prepara para suportar casos de uso do mundo real. Se houver funcionalidades adicionais que você gostaria de ver, por favor, levante uma solicitação de recurso.

Registrar autenticação básica

Alguns aplicativos fazem o uso da autenticação do navegador para proteger suas páginas. Com o Selenium, você pode automatizar a entrada de credenciais básicas de autenticação sempre que for necessário.

Predicate<URI> uriPredicate = uri -> uri.getHost().contains("your-domain.com");

((HasAuthentication) driver).register(uriPredicate, UsernameAndPassword.of("admin", "password"));
driver.get("https://your-domain.com/login");
NetworkAuthenticationHandler handler = new NetworkAuthenticationHandler()
{
    UriMatcher = (d) => d.Host.Contains("your-domain.com"),
    Credentials = new PasswordCredentials("admin", "password")
};

INetwork networkInterceptor = driver.Manage().Network;
networkInterceptor.AddAuthenticationHandler(handler);
await networkInterceptor.StartMonitoring();
require 'selenium-webdriver'

driver = Selenium::WebDriver.for :chrome

begin
  driver.devtools.new
  driver.register(username: 'username', password: 'password')
  driver.get '<your site url>'
ensure
  driver.quit
end
const {Builder} = require('selenium-webdriver');

(async function example() {
  try {
    let driver = await new Builder()
      .forBrowser('chrome')
      .build();

    const pageCdpConnection = await driver.createCDPConnection('page');
    await driver.register('username', 'password', pageCdpConnection);
    await driver.get('https://the-internet.herokuapp.com/basic_auth');
    await driver.quit();
  }catch (e){
    console.log(e)
  }
}())
val uriPredicate = Predicate { uri: URI ->
        uri.host.contains("your-domain.com")
    }
(driver as HasAuthentication).register(uriPredicate, UsernameAndPassword.of("admin", "password"))
driver.get("https://your-domain.com/login")

Interceptação de Rede

Se você quer capturar eventos de rede que chegam ao navegador e deseja manipulá-los, você pode fazer com os exemplos a seguir.

    import org.openqa.selenium.WebDriver;
    import org.openqa.selenium.devtools.HasDevTools;
    import org.openqa.selenium.devtools.NetworkInterceptor;
    import org.openqa.selenium.remote.http.Contents;
    import org.openqa.selenium.remote.http.Filter;
    import org.openqa.selenium.remote.http.HttpResponse;
    import org.openqa.selenium.remote.http.Route;

    NetworkInterceptor interceptor = new NetworkInterceptor(
      driver,
      Route.matching(req -> true)
        .to(() -> req -> new HttpResponse()
          .setStatus(200)
          .addHeader("Content-Type", MediaType.HTML_UTF_8.toString())
          .setContent(utf8String("Creamy, delicious cheese!"))));

   driver.get("https://example-sausages-site.com");

    String source = driver.getPageSource();

    assertThat(source).contains("delicious cheese!");

9 - Support Features

Support classes provide optional higher level features.

The core libraries of Selenium try to be low level and non-opinionated. The Support classes in each language provide opinionated wrappers for common interactions that may be used to simplify some behaviors.

9.1 - Trabalhando com cores

Ocasionalmente, você desejará validar a cor de algo como parte de seus testes; o problema é que as definições de cores na web não são constantes. Não seria bom se houvesse uma maneira fácil de comparar uma representação HEX de uma cor com uma representação RGB de uma cor, ou uma representação RGBA de uma cor com uma representação HSLA de uma cor?

Não se preocupe. Existe uma solução: a classe Color!

Em primeiro lugar, você precisará importar a classe:

import org.openqa.selenium.support.Color;
  
from selenium.webdriver.support.color import Color
  
// This feature is not implemented - Help us by sending a pr to implement this feature
  
include Selenium::WebDriver::Support
  
// This feature is not implemented - Help us by sending a pr to implement this feature
  
import org.openqa.selenium.support.Color

Agora você pode começar a criar objetos coloridos. Cada objeto de cor precisará ser criado a partir de uma representação de string de sua cor. As representações de cores com suporte são:

private final Color HEX_COLOUR = Color.fromString("#2F7ED8");
private final Color RGB_COLOUR = Color.fromString("rgb(255, 255, 255)");
private final Color RGB_COLOUR = Color.fromString("rgb(40%, 20%, 40%)");
private final Color RGBA_COLOUR = Color.fromString("rgba(255, 255, 255, 0.5)");
private final Color RGBA_COLOUR = Color.fromString("rgba(40%, 20%, 40%, 0.5)");
private final Color HSL_COLOUR = Color.fromString("hsl(100, 0%, 50%)");
private final Color HSLA_COLOUR = Color.fromString("hsla(100, 0%, 50%, 0.5)");
  
HEX_COLOUR = Color.from_string('#2F7ED8')
RGB_COLOUR = Color.from_string('rgb(255, 255, 255)')
RGB_COLOUR = Color.from_string('rgb(40%, 20%, 40%)')
RGBA_COLOUR = Color.from_string('rgba(255, 255, 255, 0.5)')
RGBA_COLOUR = Color.from_string('rgba(40%, 20%, 40%, 0.5)')
HSL_COLOUR = Color.from_string('hsl(100, 0%, 50%)')
HSLA_COLOUR = Color.from_string('hsla(100, 0%, 50%, 0.5)')
  
// This feature is not implemented - Help us by sending a pr to implement this feature
  
HEX_COLOUR = Color.from_string('#2F7ED8')
RGB_COLOUR = Color.from_string('rgb(255, 255, 255)')
RGB_COLOUR = Color.from_string('rgb(40%, 20%, 40%)')
RGBA_COLOUR = Color.from_string('rgba(255, 255, 255, 0.5)')
RGBA_COLOUR = Color.from_string('rgba(40%, 20%, 40%, 0.5)')
HSL_COLOUR = Color.from_string('hsl(100, 0%, 50%)')
HSLA_COLOUR = Color.from_string('hsla(100, 0%, 50%, 0.5)')
  
// Essa funcionalidade não está implementada - Nos ajude enviando um PR implementando essa funcionalidade
  
private val HEX_COLOUR = Color.fromString("#2F7ED8")
private val RGB_COLOUR = Color.fromString("rgb(255, 255, 255)")
private val RGB_COLOUR_PERCENT = Color.fromString("rgb(40%, 20%, 40%)")
private val RGBA_COLOUR = Color.fromString("rgba(255, 255, 255, 0.5)")
private val RGBA_COLOUR_PERCENT = Color.fromString("rgba(40%, 20%, 40%, 0.5)")
private val HSL_COLOUR = Color.fromString("hsl(100, 0%, 50%)")
private val HSLA_COLOUR = Color.fromString("hsla(100, 0%, 50%, 0.5)")
  

A classe Color também suporta todas as definições de cores básicas especificadas em http://www.w3.org/TR/css3-color/#html4.

private final Color BLACK = Color.fromString("black");
private final Color CHOCOLATE = Color.fromString("chocolate");
private final Color HOTPINK = Color.fromString("hotpink");
  
BLACK = Color.from_string('black')
CHOCOLATE = Color.from_string('chocolate')
HOTPINK = Color.from_string('hotpink')
  
// This feature is not implemented - Help us by sending a pr to implement this feature
  
BLACK = Color.from_string('black')
CHOCOLATE = Color.from_string('chocolate')
HOTPINK = Color.from_string('hotpink')
  
// Essa funcionalidade não está implementada - Nos ajude enviando um PR implementando essa funcionalidade
  
private val BLACK = Color.fromString("black")
private val CHOCOLATE = Color.fromString("chocolate")
private val HOTPINK = Color.fromString("hotpink")
  

Às vezes, os navegadores retornam um valor de cor “transparent” se nenhuma cor foi definida em um elemento. A classe Color também oferece suporte para isso:

private final Color TRANSPARENT = Color.fromString("transparent");
  
TRANSPARENT = Color.from_string('transparent')
  
// This feature is not implemented - Help us by sending a pr to implement this feature
  
TRANSPARENT = Color.from_string('transparent')
  
// Essa funcionalidade não está implementada - Nos ajude enviando um PR implementando essa funcionalidade
  
private val TRANSPARENT = Color.fromString("transparent")
  

Agora você pode consultar com segurança um elemento para obter sua cor / cor de fundo sabendo que qualquer resposta será analisada corretamente e convertido em um objeto Color válido:

Color loginButtonColour = Color.fromString(driver.findElement(By.id("login")).getCssValue("color"));

Color loginButtonBackgroundColour = Color.fromString(driver.findElement(By.id("login")).getCssValue("background-color"));
  
login_button_colour = Color.from_string(driver.find_element(By.ID,'login').value_of_css_property('color'))

login_button_background_colour = Color.from_string(driver.find_element(By.ID,'login').value_of_css_property('background-color'))
  
// This feature is not implemented - Help us by sending a pr to implement this feature
  
login_button_colour = Color.from_string(driver.find_element(id: 'login').css_value('color'))

login_button_background_colour = Color.from_string(driver.find_element(id: 'login').css_value('background-color'))
  
// Essa funcionalidade não está implementada - Nos ajude enviando um PR implementando essa funcionalidade
  
val loginButtonColour = Color.fromString(driver.findElement(By.id("login")).getCssValue("color"))

val loginButtonBackgroundColour = Color.fromString(driver.findElement(By.id("login")).getCssValue("background-color"))
  

Você pode então comparar diretamente os objetos coloridos:

assert loginButtonBackgroundColour.equals(HOTPINK);
  
assert login_button_background_colour == HOTPINK
  
// This feature is not implemented - Help us by sending a pr to implement this feature
  
assert(login_button_background_colour == HOTPINK)
  
// Essa funcionalidade não está implementada - Nos ajude enviando um PR implementando essa funcionalidade
  
assert(loginButtonBackgroundColour.equals(HOTPINK))
  

Ou você pode converter a cor em um dos seguintes formatos e realizar uma validação estática:

assert loginButtonBackgroundColour.asHex().equals("#ff69b4");
assert loginButtonBackgroundColour.asRgba().equals("rgba(255, 105, 180, 1)");
assert loginButtonBackgroundColour.asRgb().equals("rgb(255, 105, 180)");
  
assert login_button_background_colour.hex == '#ff69b4'
assert login_button_background_colour.rgba == 'rgba(255, 105, 180, 1)'
assert login_button_background_colour.rgb == 'rgb(255, 105, 180)'
  
// This feature is not implemented - Help us by sending a pr to implement this feature
  
assert(login_button_background_colour.hex == '#ff69b4')
assert(login_button_background_colour.rgba == 'rgba(255, 105, 180, 1)')
assert(login_button_background_colour.rgb == 'rgb(255, 105, 180)')
  
// Essa funcionalidade não está implementada - Nos ajude enviando um PR implementando essa funcionalidade
  
assert(loginButtonBackgroundColour.asHex().equals("#ff69b4"))
assert(loginButtonBackgroundColour.asRgba().equals("rgba(255, 105, 180, 1)"))
assert(loginButtonBackgroundColour.asRgb().equals("rgb(255, 105, 180)"))
  

As cores não são mais um problema.

9.2 - ThreadGuard

Esta classe está disponível apenas no Java Binding

ThreadGuard verifica se um driver é chamado apenas da mesma thread que o criou. Problemas de threading, especialmente durante a execução de testes em paralelo, podem ter erros misteriosos e difíceis de diagnosticar. Usar este wrapper evita esta categoria de erros e gerará uma exceção quando isso acontecer.

O exemplo a seguir simula um conflito de threads:

public class DriverClash {
  //thread main (id 1) criou este driver
  private WebDriver protectedDriver = ThreadGuard.protect(new ChromeDriver()); 

  static {
    System.setProperty("webdriver.chrome.driver", "<Set path to your Chromedriver>");
  }
  
  //Thread-1 (id 24) está chamando o mesmo driver causando o conflito
  Runnable r1 = () -> {protectedDriver.get("https://selenium.dev");};
  Thread thr1 = new Thread(r1);
   
  void runThreads(){
    thr1.start();
  }

  public static void main(String[] args) {
    new DriverClash().runThreads();
  }
}

O resultado mostrado abaixo:

Exception in thread "Thread-1" org.openqa.selenium.WebDriverException:
Thread safety error; this instance of WebDriver was constructed
on thread main (id 1)and is being accessed by thread Thread-1 (id 24)
This is not permitted and *will* cause undefined behaviour

Conforme visto no exemplo:

  • protectedDriver será criado no tópico principal
  • Usamos Java Runnable para ativar um novo processo e uma nova Thread para executar o processo
  • Ambas as Threads entrarão em conflito porque a thread principal não tem protectedDriver em sua memória.
  • ThreadGuard.protect lançará uma exceção.

Nota:

Isso não substitui a necessidade de usar ThreadLocal para gerenciar drivers durante a execução em paralelo.

9.3 - Trabalhando com elementos select

Select lists have special behaviors compared to other elements.

The Select object will now give you a series of commands that allow you to interact with a <select> element.

If you are using Java or .NET make sure that you’ve properly required the support package in your code. See the full code from GitHub in any of the examples below.

Note that this class only works for HTML elements select and option. It is possible to design drop-downs with JavaScript overlays using div or li, and this class will not work for those.

Types

Select methods may behave differently depending on which type of <select> element is being worked with.

Single select

This is the standard drop-down object where one and only one option may be selected.

<select name="selectomatic">
    <option selected="selected" id="non_multi_option" value="one">One</option>
    <option value="two">Two</option>
    <option value="four">Four</option>
    <option value="still learning how to count, apparently">Still learning how to count, apparently</option>
</select>

Multiple select

This select list allows selecting and deselecting more than one option at a time. This only applies to <select> elements with the multiple attribute.

<select name="multi" id="multi" multiple="multiple">
    <option selected="selected" value="eggs">Eggs</option>
    <option value="ham">Ham</option>
    <option selected="selected" value="sausages">Sausages</option>
    <option value="onion gravy">Onion gravy</option>
</select>

Create class

First locate a <select> element, then use it to initialize a Select object. Note that as of Selenium 4.5, you can’t create a Select object if the <select> element is disabled.

        WebElement selectElement = driver.findElement(By.name("selectomatic"));
        Select select = new Select(selectElement);
    select_element = driver.find_element(By.NAME, 'selectomatic')
    select = Select(select_element)
            var selectElement = driver.FindElement(By.Name("selectomatic"));
            var select = new SelectElement(selectElement);
  it 'select options' do
    select_element = driver.find_element(name: 'selectomatic')
      const selectElement = await driver.findElement(By.name('selectomatic'))
      const select = new Select(selectElement)
    val selectElement = driver.findElement(By.name("selectomatic"))
    val select = Select(selectElement)

List options

There are two lists that can be obtained:

All options

Get a list of all options in the <select> element:

        List<WebElement> optionList = select.getOptions();
    option_list = select.options
            IList<IWebElement> optionList = select.Options;
    option_elements = select_element.find_elements(tag_name: 'option')
      const optionList = await select.getOptions()
    val optionList = select.getOptions()

Selected options

Get a list of selected options in the <select> element. For a standard select list this will only be a list with one element, for a multiple select list it can contain zero or many elements.

        List<WebElement> selectedOptionList = select.getAllSelectedOptions();
    selected_option_list = select.all_selected_options
            IList<IWebElement> selectedOptionList = select.AllSelectedOptions;
      const selectedOptionList = await select.getAllSelectedOptions()
    val selectedOptionList = select.getAllSelectedOptions()

Select option

The Select class provides three ways to select an option. Note that for multiple select type Select lists, you can repeat these methods for each element you want to select.

Text

Select the option based on its visible text

        select.selectByVisibleText("Four");
    select.select_by_visible_text('Four')
            select.SelectByText("Four");
      await select.selectByVisibleText('Four')
    select.selectByVisibleText("Four")

Value

Select the option based on its value attribute

        select.selectByValue("two");
    select.select_by_value('two')
            select.SelectByValue("two");
      await select.selectByValue('two')
    select.selectByValue("two")

Index

Select the option based on its position in the list

        select.selectByIndex(3);
    select.select_by_index(3)
            select.SelectByIndex(3);
      await select.selectByIndex(3)
    select.selectByIndex(3)

Disabled options

Selenium v4.5

Options with a disabled attribute may not be selected.

    <select name="single_disabled">
      <option id="sinlge_disabled_1" value="enabled">Enabled</option>
      <option id="sinlge_disabled_2" value="disabled" disabled="disabled">Disabled</option>
    </select>
        Assertions.assertThrows(UnsupportedOperationException.class, () -> {
            select.selectByValue("disabled");
        });
    with pytest.raises(NotImplementedError):
        select.select_by_value('disabled')
            Assert.ThrowsException<InvalidOperationException>(() => select.SelectByValue("disabled"));

    expect {
      select.select_by(:value, 'disabled')
      await assert.rejects(async () => {
        await select.selectByValue("disabled")
      }, {
        name: 'UnsupportedOperationError',
    Assertions.assertThrows(UnsupportedOperationException::class.java) {
      select.selectByValue("disabled")
    }

De-select option

Only multiple select type select lists can have options de-selected. You can repeat these methods for each element you want to select.

        select.deselectByValue("eggs");
    select.deselect_by_value('eggs')
            select.DeselectByValue("eggs");
      await select.deselectByValue('eggs')
    select.deselectByValue("eggs")

10 - Troubleshooting Assistance

How to get manage WebDriver problems.

It is not always obvious the root cause of errors in Selenium.

  1. The most common Selenium-related error is a result of poor synchronization. Read about Waiting Strategies. If you aren’t sure if it is a synchronization strategy you can try temporarily hard coding a large sleep where you see the issue, and you’ll know if adding an explicit wait can help.

  2. Note that many errors that get reported to the project are actually caused by issues in the underlying drivers that Selenium sends the commands to. You can rule out a driver problem by executing the command in multiple browsers.

  3. If you have questions about how to do things, check out the Support options for ways get assistance.

  4. If you think you’ve found a problem with Selenium code, go ahead and file a Bug Report on GitHub.

10.1 - Understanding Common Errors

How to get deal with various problems in your Selenium code.

Invalid Selector Exception

CSS and XPath Selectors are sometimes difficult to get correct.

Likely Cause

The CSS or XPath selector you are trying to use has invalid characters or an invalid query.

Possible Solutions

Run your selector through a validator service:

Or use a browser extension to get a known good value:

No Such Element Exception

The element can not be found at the exact moment you attempted to locate it.

Likely Cause

  • You are looking for the element in the wrong place (perhaps a previous action was unsuccessful).
  • You are looking for the element at the wrong time (the element has not shown up in the DOM, yet)
  • The locator has changed since you wrote the code

Possible Solutions

  • Make sure you are on the page you expect to be on, and that previous actions in your code completed correctly
  • Make sure you are using a proper Waiting Strategy
  • Update the locator with the browser’s devtools console or use a browser extension like:

Stale Element Reference Exception

An element goes stale when it was previously located, but can not be currently accessed. Elements do not get relocated automatically; the driver creates a reference ID for the element and has a particular place it expects to find it in the DOM. If it can not find the element in the current DOM, any action using that element will result in this exception.

Common Causes

This can happen when:

  • You have refreshed the page, or the DOM of the page has dynamically changed.
  • You have navigated to a different page.
  • You have switched to another window or into or out of a frame or iframe.

Common Solutions

The DOM has changed

When the page is refreshed or items on the page have moved around, there is still an element with the desired locator on the page, it is just no longer accessible by the element object being used, and the element must be relocated before it can be used again. This is often done in one of two ways:

  • Always relocate the element every time you go to use it. The likelihood of the element going stale in the microseconds between locating and using the element is small, though possible. The downside is that this is not the most efficient approach, especially when running on a remote grid.

  • Wrap the Web Element with another object that stores the locator, and caches the located Selenium element. When taking actions with this wrapped object, you can attempt to use the cached object if previously located, and if it is stale, exception can be caught, the element relocated with the stored locator, and the method re-tried. This is more efficient, but it can cause problems if the locator you’re using references a different element (and not the one you want) after the page has changed.

The Context has changed

Element objects are stored for a given context, so if you move to a different context — like a different window or a different frame or iframe — the element reference will still be valid, but will be temporarily inaccessible. In this scenario, it won’t help to relocate the element, because it doesn’t exist in the current context. To fix this, you need to make sure to switch back to the correct context before using the element.

The Page has changed

This scenario is when you haven’t just changed contexts, you have navigated to another page and have destroyed the context in which the element was located. You can’t just relocate it from the current context, and you can’t switch back to an active context where it is valid. If this is the reason for your error, you must both navigate back to the correct location and relocate it.

10.2 - Logging Selenium commands

Getting information about Selenium execution.

Turning on logging is a valuable way to get extra information that might help you determine why you might be having a problem.

Getting a logger

Java logs are typically created per class. You can work with the default logger to work with all loggers. To filter out specific classes, see Filtering

Get the root logger:

    Logger logger = Logger.getLogger("");

Java Logging is not exactly straightforward, and if you are just looking for an easy way to look at the important Selenium logs, take a look at the Selenium Logger project

Python logs are typically created per module. You can match all submodules by referencing the top level module. So to work with all loggers in selenium module, you can do this:

    logger = logging.getLogger('selenium')
.NET does not currently have a Logging implementation

If you want to see as much debugging as possible in all the classes, you can turn on debugging globally in Ruby by setting $DEBUG = true.

For more fine-tuned control, Ruby Selenium created its own Logger class to wrap the default Logger class. This implementation provides some interesting additional features. Obtain the logger directly from the #loggerclass method on the Selenium::WebDriver module:

      logger = Selenium::WebDriver.logger
const logging = require('selenium-webdriver/lib/logging')
logger = logging.getLogger('webdriver')

Logger level

Logger level helps to filter out logs based on their severity.

Java has 7 logger levels: SEVERE, WARNING, INFO, CONFIG, FINE, FINER, and FINEST. The default is INFO.

You have to change both the level of the logger and the level of the handlers on the root logger:

    logger.setLevel(Level.FINE);
    Arrays.stream(logger.getHandlers()).forEach(handler -> {
      handler.setLevel(Level.FINE);
    });

Python has 6 logger levels: CRITICAL, ERROR, WARNING, INFO, DEBUG, and NOTSET. The default is WARNING

To change the level of the logger:

    logger.setLevel(logging.DEBUG)

Things get complicated when you use PyTest, though. By default, PyTest hides logging unless the test fails. You need to set 3 things to get PyTest to display logs on passing tests.

To always output logs with PyTest you need to run with additional arguments. First, -s to prevent PyTest from capturing the console. Second, -p no:logging, which allows you to override the default PyTest logging settings so logs can be displayed regardless of errors.

So you need to set these flags in your IDE, or run PyTest on command line like:

pytest -s -p no:logging

Finally, since you turned off logging in the arguments above, you now need to add configuration to turn it back on:

logging.basicConfig(level=logging.WARN)
.NET does not currently have a Logging implementation

Ruby logger has 5 logger levels: :debug, :info, :warn, :error, :fatal. As of Selenium v4.9.1, The default is :info.

To change the level of the logger:

      logger.level = :debug

JavaScript has 9 logger levels: OFF, SEVERE, WARNING, INFO, DEBUG, FINE, FINER, FINEST, ALL. The default is OFF.

To change the level of the logger:

logger.setLevel(logging.Level.INFO)

Actionable items

Things are logged as warnings if they are something the user needs to take action on. This is often used for deprecations. For various reasons, Selenium project does not follow standard Semantic Versioning practices. Our policy is to mark things as deprecated for 3 releases and then remove them, so deprecations may be logged as warnings.

Java logs actionable content at logger level WARN

Example:

May 08, 2023 9:23:38 PM dev.selenium.troubleshooting.LoggingTest logging
WARNING: this is a warning

Python logs actionable content at logger level — WARNING Details about deprecations are logged at this level.

Example:

WARNING  selenium:test_logging.py:23 this is a warning
.NET does not currently have a Logging implementation

Ruby logs actionable content at logger level — :warn. Details about deprecations are logged at this level.

For example:

2023-05-08 20:53:13 WARN Selenium [:example_id] this is a warning 

Because these items can get annoying, we’ve provided an easy way to turn them off, see filtering section below.

Useful information

This is the default level where Selenium logs things that users should be aware of but do not need to take actions on. This might reference a new method or direct users to more information about something

Java logs useful information at logger level INFO

Example:

May 08, 2023 9:23:38 PM dev.selenium.troubleshooting.LoggingTest logging
INFO: this is useful information

Python logs useful information at logger level — INFO

Example:

INFO     selenium:test_logging.py:22 this is useful information
.NET does not currently have a Logging implementation

Ruby logs useful information at logger level — :info.

Example:

2023-05-08 20:53:13 INFO Selenium [:example_id] this is useful information 

Logs useful information at level: INFO

Debugging Details

The debug log level is used for information that may be needed for diagnosing issues and troubleshooting problems.

Java logs most debug content at logger level FINE

Example:

May 08, 2023 9:23:38 PM dev.selenium.troubleshooting.LoggingTest logging
FINE: this is detailed debug information

Python logs debugging details at logger level — DEBUG

Example:

DEBUG    selenium:test_logging.py:24 this is detailed debug information
.NET does not currently have a Logging implementation

Ruby only provides one level for debugging, so all details are at logger level — :debug.

Example:

2023-05-08 20:53:13 DEBUG Selenium [:example_id] this is detailed debug information 

Logs debugging details at level: FINER and FINEST

Logger output

Logs can be displayed in the console or stored in a file. Different languages have different defaults.

By default all logs are sent to System.err. To direct output to a file, you need to add a handler:

    Handler handler = new FileHandler("selenium.xml");
    logger.addHandler(handler);

By default all logs are sent to sys.stderr. To direct output somewhere else, you need to add a handler with either a StreamHandler or a FileHandler:

    log_path = "selenium.log"
    handler = logging.FileHandler(log_path)
    logger.addHandler(handler)
.NET does not currently have a Logging implementation

By default, logs are sent to the console in stdout.
To store the logs in a file:

      logger.output = file_name

JavaScript does not currently support sending output to a file.

To send logs to console output:

logging.installConsoleHandler()

Logger filtering

Java logging is managed on a per class level, so instead of using the root logger (Logger.getLogger("")), set the level you want to use on a per-class basis:

    Logger.getLogger(RemoteWebDriver.class.getName()).setLevel(Level.FINEST);
    Logger.getLogger(SeleniumManager.class.getName()).setLevel(Level.SEVERE);
Because logging is managed by module, instead of working with just "selenium", you can specify different levels for different modules:
    logging.getLogger('selenium.webdriver.remote').setLevel(logging.WARN)
    logging.getLogger('selenium.webdriver.common').setLevel(logging.DEBUG)
.NET does not currently have a Logging implementation

Ruby’s logger allows you to opt in (“allow”) or opt out (“ignore”) of log messages based on their IDs. Everything that Selenium logs includes an ID. You can also turn on or off all deprecation notices by using :deprecations.

These methods accept one or more symbols or an array of symbols:

      logger.ignore(:jwp_caps, :logger_info)

or

      logger.allow(%i[selenium_manager example_id])
