WebDriver

WebDriverはブラウザをネイティブに操作します。詳細については、こちらをご覧ください。

WebDriverは、ユーザーがローカルまたはSeleniumサーバーを使用するリモートマシンで行うように、ブラウザをネイティブに動かし、ブラウザの自動化に関して大きく前進します。

Selenium WebDriverは言語バインディングと個々のブラウザ制御コードの実装の両方を参照します。
これは通常、単に WebDriver と呼ばれます。

Selenium WebDriverは、W3C勧告です。

  • WebDriverはシンプルでより簡潔なプログラミングインターフェイスとして設計されています。

  • WebDriverはコンパクトなオブジェクト指向APIです。

  • ブラウザーを効果的に動かします。

1 - 入門

Seleniumを初めて使用する場合は、すぐに習得するのに役立つリソースがいくつかあります。

Seleniumは市場で主要なブラウザの全てを WebDriver を使うことでサポートしています。 WebDriverとはAPI群とプロトコルです。これらはウェブブラウザの動作をコントロールするための言語中立なインターフェイスを定義しています。 それぞれのブラウザは特定のWebDriverの実装を持っており、これらは driver と呼ばれます。 driverはブラウザに委譲する責務を持つコンポーネントであり、Seleniumとブラウザ間の通信を処理します。

この分離は、ブラウザベンダーに自分たちのブラウザでの実装の責任を持たせるための意図的な努力のひとつです。 Seleniumは可能な場合これらのサードパーティ製のdriverを使いますが、それが現実的でない場合のためにプロジェクトでメンテナンスしているdriverも提供しています。

Seleniumフレームワークはこれら全ての要素をユーザ向けのインターフェイスを通して結びつけます。このインターフェイスは異なるブラウザバックエンドを透過的に使えるようにし、クロスブラウザ・クロスプラットフォームの自動化を可能にします。

Seleniumのセットアップは他の商用ツールと少し違います。自動化プロジェクトでSeleniumを使うためには、選択した言語の言語バインディングライブラリをインストールする必要があります。加えて、自動化でテストを実行したいブラウザのWebDriverバイナリも必要となります。

Seleniumのインストールは、次の3つのステップに分類することができます。

  1. 希望するプログラミング言語のSeleniumライブラリをインストールする。
  2. ブラウザを自動化するようにブラウザードライバを設定する。(例:Firefox用のGeckoDriver)
  3. (オプション)テストをスケールアップする場合は、Selenium Gridをセットアップして構成する。

ローコード/記録および再生ツールから始めたい場合は、Selenium IDE をチェックしてください。

セットアップが完了したら、ドキュメントのトップページに表示されているコードスニペットを実行できます。 次に、WebDriverの章に移動して、Seleniumを使用したブラウザーの自動化について詳しく学びます。

1.1 - Seleniumライブラリのインストール

お気に入りのプログラミング言語用にSeleniumライブラリを設定します。

最初にあなたの自動化プロジェクトにSeleniumのバインディングをインストールする必要があります。 インストールの方法は選択した言語によって異なります。

Requirements by language

View the minimum supported Java version here.

Installation of Selenium libraries for Java is accomplished using a build tool.

Maven

Specify the dependency in the project’s pom.xml file:

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

Gradle

Specify the dependency in the project build.gradle file as testImplementation:

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

The minimum supported Python version for each Selenium version can be found in Supported Python Versions on PyPi

There are a couple different ways to install Selenium.

Pip

pip install selenium

Download

Alternatively you can download the PyPI source archive (selenium-x.x.x.tar.gz) and install it using setup.py:

python setup.py install

Require in project

To use it in a project, add it to the requirements.txt file:

selenium==4.8.2

A list of all supported frameworks for each version of Selenium is available on Nuget

There are a few options for installing Selenium.

Packet Manager

Install-Package Selenium.WebDriver

.NET CLI

dotnet add package Selenium.WebDriver

CSProj

in the project’s csproj file, specify the dependency as a PackageReference in ItemGroup:

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

Additional considerations

Further items of note for using Visual Studio Code (vscode) and C#

Install the compatible .NET SDK as per the section above. Also install the vscode extensions (Ctrl-Shift-X) for C# and NuGet. Follow the instruction here to create and run the “Hello World” console project using C#. You may also create a NUnit starter project using the command line dotnet new NUnit. Make sure the file %appdata%\NuGet\nuget.config is configured properly as some developers reported that it will be empty due to some issues. If nuget.config is empty, or not configured properly, then .NET builds will fail for Selenium Projects. Add the following section to the file nuget.config if it is empty:

<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>
...

For more info about nuget.config click here. You may have to customize nuget.config to meet you needs.

Now, go back to vscode, press Ctrl-Shift-P, and type “NuGet Add Package”, and enter the required Selenium packages such as Selenium.WebDriver. Press Enter and select the version. Now you can use the examples in the documentation related to C# with vscode.

You can see the minimum required version of Ruby for any given Selenium version on rubygems.org

Selenium can be installed two different ways.

Install manually

gem install selenium-webdriver

Add to project’s gemfile

gem 'selenium-webdriver', '= 4.8.0'

You can find the minimum required version of Node for any given version of Selenium in the Node Support Policy section on npmjs

Selenium is typically installed using npm.

Install locally

npm install selenium-webdriver

Add to project

In your project’s package.json, add requirement to dependencies:

        "selenium-webdriver": "^4.8.1"
Use the Java bindings for Kotlin.

Next Step

Install the browser drivers

1.2 - ブラウザーのドライバーをインストールする

自動化するブラウザを設定する。

Seleniumは、WebDriverを介して、Chrome/Chromium、Firefox、Internet Explorer、Edge、Safari などの市場にあるすべての主要なブラウザーをサポートします。 可能な場合、WebDriverは、ブラウザーに組み込まれている自動化のサポートを使用してブラウザーを動かします。

Internet Explorerを除くすべてのドライバーの実装は、ブラウザーベンダー自身によって提供されているため、 標準のSeleniumディストリビューションには含まれていません。 この章では、さまざまなブラウザを使い始めるための基本的な要件について説明します。

Read about more advanced options for starting a driver in our driver configuration documentation.

Four Ways to Use Drivers

1. Selenium Manager (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. ドライバー管理ソフトウェア

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. PATH 環境変数

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

このオプションでは、最初に手動でドライバーをダウンロードする必要があります (リンクについてはクイックリファレンスを参照してください)。

これは、コードを更新せずにドライバーの場所を変更するための柔軟なオプションであり、各マシンがドライバーを同じ場所に配置する必要なく、複数のマシンで機能します。

PATH にすでにリストされているディレクトリにドライバを配置するか、ディレクトリに配置して PATH に追加することができます。

  • すでに PATH にあるディレクトリを確認するには、コマンドプロンプト/ターミナルを開いて次のように入力します。

To see what directories are already on PATH, open a Terminal and execute:

echo $PATH

If the location to your driver is not already in a directory listed, you can add a new directory to 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

To see what directories are already on PATH, open a Terminal and execute:

echo $PATH

If the location to your driver is not already in a directory listed, you can add a new directory to 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

To see what directories are already on PATH, open a Command Prompt and execute:

echo %PATH%

If the location to your driver is not already in a directory listed, you can add a new directory to 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

  • If your PATH is configured correctly, 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. ハードコードされた場所

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

上記のオプション3と同様に、ドライバーを手動でダウンロードする必要があります。 (リンクについては クイックリファレンス を参照してください)。 コードそのものに場所を指定することには、システム上の環境変数を把握する必要がないという利点がありますが、 コードの柔軟性が大幅に低下するという欠点があります。

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

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

const service = new chrome.ServiceBuilder('/opt/WebDriver/bin/chromedriver');
const driver = new Builder().forBrowser('chrome').setChromeService(service).build();
// Please raise a PR to add code sample

Next Step

Create your first Selenium script

1.3 - 最初のSeleniumスクリプトを書く

Seleniumスクリプトを作成するための段階的な説明

Seleniumをインストールし、 ドライバーをインストールすると、Seleniumコードを書く準備が整います。

Eight Basic Components

Seleniumが行うことはすべて、ブラウザコマンドを送信して、何かを実行したり、情報の要求を送信したりすることです。 Seleniumで行うことのほとんどは、次の基本的なコマンドの組み合わせです。

1. ドライバーインスタンスでセッションを開始します

For more details on starting a session read our documentation on 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. Take action on browser

In this example we are ブラウザがナビゲートするコマンドを送信します

        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. ブラウザに関する情報をリクエストします

There are a bunch of types of information about the browser you can request, including window handles, browser size / position, cookies, alerts, etc.

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

4. Establish Waiting Strategy

Synchronizing the code with the current state of the browser is one of the biggest challenges with Selenium, and doing it well is an advanced topic.

Essentially you want to make sure that the element is on the page before you attempt to locate it and the element is in an interactable state before you attempt to interact with it.

An implicit wait is rarely the best solution, but it’s the easiest to demonstrate here, so we’ll use it as a placeholder.

Read more about Waiting strategies.

        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. 要素を検索するためのコマンドを送信します

The majority of commands in most Selenium sessions are element related, and you can’t interact with one without first finding an element

        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. 要素に対してアクションを実行する

There are only a handful of actions to take on an element, but you will use them frequently.

        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. 要素に関する情報をリクエストします

Elements store a lot of information that can be requested.

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

8. セッションを終了します

This ends the driver process, which by default closes the browser as well. No more commands can be sent to this driver instance.

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

1.4 - Selenium4にアップグレードする方法

Selenium 4に興味がありますか? 最新リリースへのアップグレードに役立つこのガイドを確認してください。

公式にサポートされている言語(Ruby、JavaScript、C#、Python、およびJava)のいずれかを使用している場合、 Selenium4へのアップグレードは簡単なプロセスです。 いくつかの問題が発生する可能性がある場合があるかもしれません。このガイドは、それらを整理するのに役立ちます。 プロジェクトの依存関係をアップグレードする手順を実行し、バージョンのアップグレードによってもたらされる主な非推奨と変更を理解します。

これが、Selenium4にアップグレードするために実行する手順です。

  • テストコードの準備
  • 依存関係のアップグレード
  • 潜在的なエラーと非推奨メッセージ

注:Selenium 3.xバージョンの開発中に、W3CWebDriver標準のサポートが実装されました。 この新しいプロトコルと従来のJSONワイヤープロトコルの両方がサポートされました。 バージョン3.11の前後で、SeleniumコードはレベルW3C1仕様に準拠するようになりました。 Selenium 3の最新バージョンのW3C準拠のコードは、Selenium4で期待どおりに機能します。

テストコードの準備

Selenium 4は、レガシープロトコルのサポートを削除し、内部でデフォルトでW3CWebDriver標準を使用します。 ほとんどの場合、この実装はエンドユーザーに影響を与えません。 主な例外は、Capabilitiesアクション クラスです。

Capabilities

テスト機能がW3Cに準拠するように構成されていない場合、セッションが開始されない可能性があります。 W3CWebDriverの標準機能のリストは次のとおりです。

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

標準Capabilitiesの最新リストは、 W3C WebDriver にあります。

上記のリストに含まれていないCapabilitiesには、ベンダープレフィックスを含める必要があります。 これは、ブラウザ固有のCapabilitiesとクラウドベンダー固有のCapabilitiesに適用されます。 たとえば、クラウドベンダーがテストに build Capabilities と name Capabilitiesを使用している場合は、 それらを cloud:options ブロックでラップする必要があります(適切なプレフィックスについては、クラウドベンダーに確認してください)。

Before

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)

After

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";
var cloudOptions = new Dictionary<string, object>();
cloudOptions.Add("build", myTestBuild);
cloudOptions.Add("name", myTestName);
browserOptions.AddAdditionalOption("cloud:options", cloudOptions);
var driver = new RemoteWebDriver(new Uri(CloudURL), browserOptions);
options = Selenium::WebDriver::Options.firefox
options.browser_version = 'latest'
options.platform_name = 'Windows 10'
cloud_options = {}
cloud_options[:build] = my_test_build
cloud_options[:name] = my_test_name

Javaで要素ユーティリティメソッドを検索する

Javaバインディング(FindsBy インターフェイス)の要素を検索するユーティリティメソッドは、内部使用のみを目的としていたため、削除されました。 次のコードサンプルは、これを分かりやすく説明しています。

findElement * で単一の要素を検索する。

Before

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

After

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"));

findElements * で複数の要素を検索する。

Before

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

After

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"));

依存関係のアップグレード

以下のサブセクションを確認してSelenium4をインストールし、プロジェクトの依存関係をアップグレードしてください。

Java

Seleniumをアップグレードするプロセスは、使用されているビルドツールによって異なります。 Javaで最も一般的なものであるMavenGradleについて説明します。 必要なJavaの最小バージョンはまだ8です。

Maven

Before

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

After

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

変更を加えた後、pom.xml ファイルと同じディレクトリで mvn clean compile を実行できます。

Gradle

Before

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()
}

After

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()
}

変更を加えた後、 build.gradle ファイルと同じディレクトリで ./gradlew cleanbuild を実行できます。

すべてのJavaリリースを確認するには、 MVNRepository にアクセスしてください。

C#

C#でSelenium4の更新を取得する場所は NuGet です。 Selenium.WebDriver パッケージの下で、最新バージョンに更新するための手順を入手できます。 Visual Studio内では、NuGetパッケージマネージャーを使用して次の操作を実行できます。

PM> Install-Package Selenium.WebDriver -Version 4.4.0

Python

Pythonを使用するための最も重要な変更は、最低限必要なバージョンです。 Selenium 4には、Python3.7以降が必要です。 詳細については、Python Package Indexを参照してください。 コマンドラインからアップグレードするには、次のコマンドを実行できます。

pip install selenium==4.4.3

Ruby

Selenium 4の更新の詳細は、RubyGemsのselenium-webdriverで確認できます。 最新バージョンをインストールするには、次のコマンドを実行できます。

gem install selenium-webdriver

Gemfileには下記のように追加します。

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

JavaScript

selenium-webdriverパッケージは、Nodeパッケージマネージャーのnpmjsにあります。 Selenium4はhereにあります。 これをインストールするには、次のいずれかを実行します。

npm install selenium-webdriver

または、package.jsonを更新して、 npm install を実行します。

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

潜在的なエラーと非推奨メッセージ

これは、Selenium4にアップグレードした後に発生する可能性のある非推奨メッセージを克服するのに役立つ一連のコード例です。

Java

待機とタイムアウト

タイムアウトで受信するパラメーターは、期待値 (long time, TimeUnit unit) から期待値 (Duration duration) に替わりました。

Before

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

After

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

現在、待機も異なるパラメーターを期待しています。 WebDriverWaitは、秒とミリ秒単位のタイムアウトに、 long ではなくDurationを期待するようになりました。 FluentWaitwithTimeout および pollingEvery ユーティリティメソッドは、期待値 (long time, TimeUnit unit) から (Duration duration) に替わりました。

Before

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);

After

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);

マージCapabilitiesは、もはや呼び出し元のオブジェクトを変更しなくなりました

以前は、別のCapabilitiesセットを別のセットにマージすることが可能であり、呼び出し元のオブジェクトを変更していました。 今は、ここで、マージ操作の結果を割り当てる必要があります。

Before

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

As a result, the options object was getting modified.

After

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

The result of the merge call needs to be assigned to an object.

古いFirefox

GeckoDriverが登場する前は、SeleniumプロジェクトにはFirefoxを自動化するためのドライバー実装がありました(バージョン<48)。 ただし、この実装は最近のバージョンのFirefoxでは機能しないため、もう必要ありません。 Selenium 4にアップグレードする際の大きな問題を回避するために、setLegacy オプションは非推奨として表示されます。 古い実装の使用をやめ、GeckoDriverのみに依存することをお勧めします。 次のコードは、アップグレード後に非推奨になったsetLegacy 行を示しています。

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

BrowserType

BrowserType インターフェースは長い間使用されてきましたが、新しい Browser インターフェースを優先して非推奨になります。

Before

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

After

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

C#

AddAdditionalCapability は非推奨になりました

その代わりに、 AddAdditionalOption をお勧めします。 これを示す例を次に示します。

Before

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

After

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

Python

execute_pathは非推奨になりました。Serviceオブジェクトを渡してください

Selenium 4では、非推奨の警告を防ぐために、Serviceオブジェクトからドライバーの executable_path を設定する必要があります。 (または、PATHを設定せず、代わりに必要なドライバーがシステムPATH上にあることを確認してください。)

Before

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)

After

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)

まとめ

Selenium 4にアップグレードする際に考慮すべき主な変更点を確認しました。 アップグレードのためにテストコードを準備する際にカバーするさまざまな側面について説明します。 これには、新しいバージョンのSeleniumを使用する時に発生する可能性のある潜在的な問題を防ぐ方法の提案も含まれます。 最後に、アップグレード後に発生する可能性のある一連の問題についても説明し、それらの問題に対する潜在的な修正を共有しました。

これは元々は https://saucelabs.com/resources/articles/how-to-upgrade-to-selenium-4 に投稿されました

2 - ドライバーセッション

セッションの開始と停止は、ブラウザーを開いたり閉じたりするためのものです。

セッションの作成

新しいセッションの作成は、W3C コマンド New session に対応しています。

セッションは、新しいDriverクラスオブジェクトを初期化することによって自動的に作成されます。

各言語では、次のいずれかのクラス (または同等のもの) の引数を使用してセッションを作成することができます。

ローカルドライバー

ローカルドライバーを起動するための主な一意の引数には、ローカルコンピューターで必要なドライバーサービスを起動するための情報が含まれます。

  • Serviceオブジェクトはローカルドライバーにのみ適用され、ブラウザーのドライバーに関する情報を提供します。

リモートドライバー

リモートドライバーを起動するための主な一意の引数には、コードを実行する場所に関する情報を含みます。 詳細は、リモートドライバーをご覧ください。

セッションの終了

セッションの終了に対するW3Cコマンドは、セッションの削除です。

重要: quit メソッドは close メソッドとは異なり、 セッションを終了するには常に quit を使用することをお勧めします。

2.1 - ブラウザーオプション

これらのCapabilityはすべてのブラウザで共通です。

Selenium 3 では、Capabilitiesは Desired Capabilities クラスを使用してセッションで定義していました。 Selenium 4 以降、ブラウザ オプション クラスを使用する必要があります。 リモート ドライバー セッションの場合、使用するブラウザーを決めるため、ブラウザーオプションインスタンスが必要です。

これらのオプションは、Capabilities の w3c仕様で説明しています。

各ブラウザには、w3c仕様で定義しているものに加えて定義可能な カスタム オプション があります。

browserName

このCapabilityは、特定のセッションの browserName を設定するために使います。 指定されたブラウザがリモートエンドにインストールされていない場合、セッションの作成は失敗します。

browserVersion

このCapabilityはオプションです。 これは、リモートエンドで使用可能なブラウザーバージョンを設定するために使います。 たとえば、Chromeバージョン80のみがインストールされているシステムでバージョン75を要求すると、セッションの作成は失敗します。

pageLoadStrategy

3種類のページ読み込み戦略を利用できます。

ページ読み込み戦略は、次の表で説明しています。

戦略 準備完了状態 注釈
normal complete デフォルトで使用され、すべてのリソースをダウンロードするのを待ちます
eager interactive DOM アクセスの準備は整っていますが、画像などの他のリソースはまだロード中の可能性があります
none Any WebDriver をまったくブロックしません

ドキュメントの document.readyState プロパティは、現在のドキュメントの読み込み状態を示します。

URL 経由で新しいページに移動する場合、デフォルトでは、WebDriver は、ドキュメントの準備完了状態が完了するまで、 ナビゲーション メソッド (driver.navigate().get() など) の完了を保留します。 これは必ずしもページの読み込みが完了したことを意味するわけではありません。 特に、Ready State が完了した後に JavaScript を使用してコンテンツを動的に読み込むシングル ページ アプリケーションのようなサイトの場合はそうです。 また、この動作は、要素のクリックまたはフォームの送信の結果であるナビゲーションには適用されないことに注意してください。

自動化にとって重要ではないアセット (画像、css、js など) をダウンロードした結果、ページの読み込みに時間がかかる場合は、 デフォルトのパラメーターである normaleager または none に変更して、セッションの読み込みを高速化できます。 この値はセッション全体に適用されるため、 待機戦略 が不安定さを最小限に抑えるのに十分であることを確認してください。

normal (デフォルト)

WebDriver は load イベント検知するまで待機します。

    driver.quit()
  }
}

platformName

これにより、リモートエンドのオペレーティングシステムが識別され、 platformName を取得するとOS名が返されます。

クラウドベースのプロバイダーでは、 platformName を設定すると、リモートエンドのOSが設定されます。

acceptInsecureCerts

この機能は、セッション中のナビゲーション中に、期限切れ(または)無効な TLS証明書 が使用されているかどうかを確認します。

機能が false に設定されている場合、ナビゲーションでドメイン証明書の問題が発生すると、 insecure certificate error が返されます。 true に設定すると、無効な証明書はブラウザーによって信頼されます。

すべての自己署名証明書は、デフォルトでこの機能によって信頼されます。 一度設定すると、 acceptInsecureCerts Capabilityはセッション全体に影響します。

timeouts

WebDriverの セッション には特定の セッションタイムアウト 間隔が設定されており、 その間、ユーザーはスクリプトの実行またはブラウザーからの情報の取得の動作を制御できます。

各セッションタイムアウトは、以下で説明するように、異なる タイムアウト の組み合わせで構成されます。

Script Timeout:

現在のブラウジングコンテキストで実行中のスクリプトをいつ中断するかを指定します。 新しいセッションがWebDriverによって作成されると、デフォルトのタイムアウト 30,000 が課されます。

Page Load Timeout:

現在のブラウジングコンテキストでWebページをロードする必要がある時間間隔を指定します。 新しいセッションがWebDriverによって作成されると、デフォルトのタイムアウト 300,000 が課されます。 ページの読み込みが指定/デフォルトの時間枠を制限する場合、スクリプトは TimeoutException によって停止されます。

Implicit Wait Timeout

これは、要素を検索するときに暗黙的な要素の検索戦略を待つ時間を指定します。 新しいセッションがWebDriverによって作成されると、デフォルトのタイムアウト 0 が課されます。

unhandledPromptBehavior

現在のセッションの ユーザープロンプトハンドラー の状態を指定します。 デフォルトでは、 dismiss and notify (却下して通知する) 状態 となります。

User Prompt Handler

これは、リモートエンドでユーザープロンプトが表示されたときに実行する必要があるアクションを定義します。 これは、 unhandledPromptBehavior Capabilityによって定義され、次の状態があります。

  • dismiss (却下)
  • accept (受入)
  • dismiss and notify (却下して通知)
  • accept and notify (受け入れて通知)
  • ignore (無視)

setWindowRect

リモート エンドがすべての サイズ変更および再配置 コマンド をサポートするかどうかを示します。

strictFileInteractability

この新しいcapabilityは、厳密な相互作用チェックを input type = file 要素に適用する必要があるかどうかを示します。 厳密な相互作用チェックはデフォルトでオフになっているため、隠しファイルのアップロードコントロールで Element Send Keys を使用する場合の動作が変更されます。

proxy

プロキシサーバーは、クライアントとサーバー間の要求の仲介役として機能します。 簡単に言えば、トラフィックはプロキシサーバーを経由して、要求したアドレスに戻り、戻ってきます。

Seleniumを使用した自動化スクリプト用のプロキシサーバーは、

  • ネットワークトラフィックをキャプチャする
  • ウェブサイトによって行われた模擬バックエンドを呼び出す
  • 複雑なネットワークトポロジーまたは厳格な企業の制限/ポリシーの下で、必要なWebサイトにアクセスします。

企業環境でブラウザがURLへの接続に失敗した場合、環境にアクセスするにはプロキシが必要であることが原因であることが最も可能性が高いです。

Selenium WebDriverは設定をプロキシする方法を提供します。

public class proxyTest {

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

WebDriverは、ローカルで使用するのと同じ方法でリモートで使用できます。 主な違いは、リモートWebDriverを設定して、別のマシンでテストを実行できるようにする必要があることです。

リモートWebDriverは、クライアントとサーバーの2つの部分で構成されています。 クライアントはWebDriverテストであり、サーバーは単純なJavaサーブレットで最新のJEEアプリサーバーでホストすることができます。

リモートWebDriverクライアントを実行するには、まずRemoteWebDriverに接続する必要があります。 これを行うには、テストを実行しているサーバーのアドレスをURLに指定します。 設定をカスタマイズするために、desired capabilitiesを設定します。 以下は、Firefoxでテストを実行しているリモートWebサーバー www.example.com を指定してリモートWebDriverオブジェクトをインスタンス化する例です。

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

テスト設定をさらにカスタマイズするために、他のdesired capabilitiesを追加できます。

ブラウザーオプション

例えば、Chromeバージョン67を使用して、Windows XPでChromeを実行する場合は、このようになるかと思います。

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()
  

ローカルファイルDetector

ローカルファイルDetectorを使用すると、クライアントマシンからリモートサーバーにファイルを転送できます。 例えば、テストでファイルをWebアプリケーションにアップロードする必要がある場合、リモートWebDriverは実行時にローカルマシンからリモートWebサーバーにファイルを自動的に転送できます。 これにより、テストを実行しているリモートマシンからファイルをアップロードできます。 デフォルトでは有効になっておらず、次の方法で有効にできます。

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()
  

上記のコードを定義したら、次の方法でテストにファイルをアップロードできます。

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")
  

クライアントのリクエストをトレースする

この機能は、Java クライアント バインディング (ベータ版以降) でのみ利用できます。 Remote WebDriver クライアントは Selenium Grid サーバーにリクエストを送信し、 Selenium Grid サーバーはリクエストを WebDriver に渡します。 HTTP リクエストをエンド ツー エンドでトレースするには、サーバー側とクライアント側でトレースを有効にする必要があります。 両端には、視覚化フレームワークを指すトレース エクスポーターのセットアップが必要です。 デフォルトでは、トレースはクライアントとサーバーの両方で有効になっています。 視覚化フレームワークの Jaeger UI と Selenium Grid 4 を設定するには、目的のバージョンの トレースのセットアップ を参照してください。

クライアント側のセットアップについては、以下の手順に従ってください。

必要な依存関係を追加する

トレーシング エクスポーターの外部ライブラリのインストールは、Maven を使って実行できます。 プロジェクト pom.xml に opentelemetry-exporter-jaeger および grpc-netty の依存関係を追加します。

  <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>

クライアントの実行中に必要なシステムプロパティを追加/渡す

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();

  

ご希望のSeleniumのバージョンに必要な外部依存関係のバージョンの詳細については、 トレースのセットアップ を参照してください。

3 - 対応ブラウザ

各ブラウザには、カスタムCapabilityと固有の機能があります。

3.1 - Chrome固有の機能

これらは、Google Chrome ブラウザに固有のCapabilityです。

デフォルトでは、Selenium 4 は Chrome v75 以降と互換性があります。 Chromeブラウザのバージョンと chromedriverのバージョンは、メジャーバージョンと一致する必要があることに注意してください。

Options

全てのブラウザに共通のCapabilityについては、オプション ページで説明しています。

Chrome に固有のCapabilityは、Google のCapabilities & ChromeOptionsページにあります。

基本的な定義済みオプションを使用してChromeセッションを開始すると、次のようになります。

        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();

さまざまなCapabilityを備えた一般的な使用例をいくつか示します。

引数

args パラメータは、ブラウザの起動時に使用されるコマンドラインスイッチのリストです。
一般的に使用される引数には、--start-maximized および --headless=new が含まれます。

オプションに引数を追加します。

        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();

指定したロケーションでブラウザを起動する

binaryパラメーターは、使用するブラウザの別のロケーションのパスを取ります。 このパラメーターを使用すると、chromedriver を使用して、さまざまな Chromium ベースのブラウザを駆動できます。

オプションにブラウザのロケーションを追加します。

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

拡張機能を追加する

extensions パラメーターはcrxファイルを受け入れます

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

オプションに拡張機能を追加します。

ブラウザを開いたままにする

detach パラメータをtrueに設定すると、ドライバープロセスが終了した後もブラウザを開いたままにできます。

オプションにバイナリを追加します。

        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();

引数を除外する

Chrome はさまざまな引数を追加します。 これらの引数を追加したくない場合は、それらを excludeSwitches に渡します。 一般的な例は、ポップアップブロッカーをオンに設定することです。

オプションに除外された引数を設定します。

    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();

    let driver = new Builder()
      .setFirefoxOptions(options.addArguments('--headless'))
      .build();

指定したロケーションでブラウザを起動する

binary パラメーターは、使用するブラウザーの別のロケーションのパスを取ります。 たとえば、このパラメーターを使用すると、geckodriver を使用して、製品版とFirefox Nightlyの両方がコンピューターに存在する場合、 製品版の代わりに Firefox Nightly を駆動できます 。

オプションにブラウザーのロケーションを追加します。

プロファイル

Firefoxプロファイルを操作するにはいくつかの方法があります。

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)
  

アドオン

Chromeとは異なり、Firefoxの拡張機能はCapabilityの一部として追加されるのではなく、ドライバーの起動後に作成されます。

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.

インストール

Mozilla Add-Onsページ から取得する署名付きxpiファイル

        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)

アンインストール

アドオンをアンインストールするには、そのIDを知る必要があります。 IDはアドオンインストール時の戻り値から取得できます。

        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)

署名なしのインストール

未完成または未公開の拡張機能を使用する場合、署名されていない可能性があります。 そのため、“一時的なもの” としてのみインストールできます。 これは、zipファイルまたはディレクトリを渡すことで実行できます。ディレクトリの例を次に示します。

        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 - IE specific functionality

These are capabilities and features specific to Microsoft Internet Explorer browsers.

As of June 2022, Selenium officially no longer supports standalone Internet Explorer. The Internet Explorer driver still supports running Microsoft Edge in “IE Compatibility Mode.”

Special considerations

The IE Driver is the only driver maintained by the Selenium Project directly. While binaries for both the 32-bit and 64-bit versions of Internet Explorer are available, there are some known limitations with the 64-bit driver. As such it is recommended to use the 32-bit driver.

Additional information about using Internet Explorer can be found on the IE Driver Server page

Options

Starting a Microsoft Edge browser in Internet Explorer Compatibility mode with basic defined options looks like this:

        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)

As of Internet Explorer Driver v4.5.0:

  • If IE is not present on the system (default in Windows 11), you do not need to use the two parameters above. IE Driver will use Edge and will automatically locate it.
  • If IE and Edge are both present on the system, you only need to set attaching to Edge, IE Driver will automatically locate Edge on your system.

As of Internet Explorer Driver v4.7.0:

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

Here are a few common use cases with different capabilities:

fileUploadDialogTimeout

環境によっては、ファイルアップロードダイアログを開くときにInternet Explorerがタイムアウトする場合があります。 IEDriverのデフォルトのタイムアウトは1000ミリ秒ですが、fileUploadDialogTimeout capabilityを使用してタイムアウトを増やすことができます。

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)

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

この機能を true に設定すると、手動またはドライバーによって開始されたものを含め、 InternetExplorerの実行中のすべてのインスタンスのキャッシュ、ブラウザー履歴、およびCookieがクリアされます。 デフォルトでは、false に設定されています。

この機能を使用すると、ドライバーがIEブラウザーを起動する前にキャッシュがクリアされるまで待機するため、 ブラウザーの起動中にパフォーマンスが低下します。

このケイパビリティは、ブール値をパラメーターとして受け入れます。

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)

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

InternetExplorerドライバーは、ブラウザーのズームレベルが100%であることを想定しています。 それ以外の場合、ドライバーは例外をスローします。 このデフォルトの動作は、 ignoreZoomSettingtrue に設定することで無効にできます。

このケイパビリティは、ブール値をパラメーターとして受け入れます。

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)

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

新しいIEセッションの起動中に 保護モード チェックをスキップするかどうか。

設定されておらず、 保護モード 設定がすべてのゾーンで同じでない場合、 ドライバーによって例外がスローされます。

ケイパビリティを true に設定すると、テストが不安定になったり、応答しなくなったり、 ブラウザがハングしたりする場合があります。 ただし、これはまだ2番目に良い選択であり、最初の選択は 常に 各ゾーンの保護モード設定を手動で実際に設定することです。 ユーザーがこのプロパティを使用している場合、「ベストエフォート」のみがサポートされます。

このケイパビリティは、ブール値をパラメーターとして受け入れます。

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)

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

IE Command-Line Options

Internet Explorerには、ブラウザーのトラブルシューティングと構成を可能にするいくつかのコマンドラインオプションが含まれています。

次に、サポートされているいくつかのコマンドラインオプションについて説明します。

  • -private : IEをプライベートブラウジングモードで起動するために使用されます。 これはIE 8以降のバージョンで機能します。

  • -k : Internet Explorerをキオスクモードで起動します。 ブラウザは、アドレスバー、ナビゲーションボタン、またはステータスバーを表示しない最大化されたウィンドウで開きます。

  • -extoff : アドオンなしモードでIEを起動します。 このオプションは、ブラウザーのアドオンに関する問題のトラブルシューティングに特に使用されます。 IE 7以降のバージョンで動作します。

注:コマンドライン引数が機能するためには、 forceCreateProcessApi を順番に有効にする必要があります。

3.5 - Safari specific functionality

These are capabilities and features specific to Apple Safari browsers.

Unlike Chromium and Firefox drivers, the safaridriver is installed with the Operating System. To enable automation on Safari, run the following command from the terminal:

safaridriver --enable

Options

Capabilities common to all browsers are described on the Options page.

Capabilities unique to Safari can be found at Apple’s page About WebDriver for Safari

Starting a Safari session with basic defined options looks like this:

        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

Those looking to automate Safari on iOS should look to the Appium project.

Safari Technology Preview

Apple provides a development version of their browser — Safari Technology Preview To use this version in your code:

4 - 待機

WebDriverは一般にブロッキングAPIを持っていると言えます。 ブラウザーに処理を 指示する Out-of-Processライブラリであり、Webプラットフォームは本質的に非同期の性質を持っているため、WebDriverはDOMのアクティブでリアルタイムな状態を追跡しません。 このことは、ここで説明するいくつかの課題が出てきます。

経験から、SeleniumとWebDriverの使用から生じる断続的なもののほとんどは、ブラウザーとユーザーの指示の間で発生する 競合状態 に関連しています。 たとえば、ユーザーがブラウザーにページに移動するように指示し、要素を見つけようとすると、no such element エラーが表示される場合があります。

次のドキュメントを考えてみましょう。

<!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>

WebDriverの指示は十分問題なく見えるかもしれません。

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!")
  

ここでは、WebDriverで使用されるデフォルトの ページロード戦略document.readyStateをリッスンして、ナビゲーションの呼び出しから戻る前に"complete"に変更することが問題です。ドキュメントの読み込みが完了した後にp要素が追加されるため、このWebDriverスクリプトは断続的になる 可能性があります。 これらのイベントを明示的に待機(またはブロック)せずに非同期でトリガーする要素またはイベントについては保証できないため、断続的である可能性があります。

幸いなことに、 WebElement.clickWebElement.sendKeys などのWebElementインターフェイスで使用可能な通常の命令セットを使用すると、コマンドの呼び出しがブラウザーで完了するまで関数呼び出しが返されない(または、コールバックはコールバックスタイルの言語ではトリガーされない)ため、同期が保証されます。高度なユーザーインタラクションAPIであるキーボードマウスは、 “言うことをする” 非同期コマンドとして明示的に意図されているため、例外です。

待機とは、自動化されたタスクの実行を一定時間経過させてから次のステップに進むことです。

ブラウザーとWebDriverスクリプト間の競合状態の問題を克服するために、ほとんどのSeleniumクライアントには待機パッケージが付属しています。待機を使用する場合、一般に明示的な待機と呼ばれるものを使用しています。

明示的な待機

Seleniumクライアントは、命令型の手続き型言語の 明示的な待機 を利用できます。 これにより、 条件 が解決するまで、コードでプログラムの実行を停止したり、スレッドをフリーズしたりできます。 条件は、明示的な待機のタイムアウトが経過するまで特定の頻度で呼び出されます。 つまり、条件がfalseの値を返す限り、試行、待機し続けます。

明示的な待機により条件が発生するのを待機できるため、ブラウザーとそのDOM、およびWebDriverスクリプトの間で状態を同期するのに適しています。

以前のバグのある命令セットを修正するには、スクリプトから動的に追加された要素がDOMに追加されるまで、 findElement 呼び出しを待機させるために待機を採用できます。

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)
  

戻り値がtrueになるまで 待機 が繰り返し実行される関数リファレンスとして 条件 を渡します。 “真の"戻り値とは、文字列、数値、ブール値、オブジェクト( WebElement を含む)、または入力された(空でない)シーケンスまたはリストなど、手元の言語でブール値trueと評価されるものです。 つまり、 空のリスト はfalseと評価されます。 条件がtrueで、ブロッキング待機が中止されると、条件からの戻り値が待機の戻り値になります。

このナレッジと、ウェイトユーティリティはデフォルトで no such element エラーを無視するため、より簡潔になるように命令をリファクタリングできます。

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!")
  

この例では、匿名関数を渡します(ただし、以前に行ったように明示的に定義して再利用できるようにすることもできます)。 条件に渡される最初で唯一の引数は、常にドライバーオブジェクト WebDriver への参照です。 マルチスレッド環境では、外部スコープ内のドライバーへのリファレンスではなく、条件に渡されたドライバーのリファレンスを操作するように注意する必要があります。

待機は、要素が見つからないときに発生する no such element エラーを飲み込むため、要素が見つかるまで条件は再試行されます。 次に、戻り値である WebElement を取得して、スクリプトに渡します。

条件が失敗した場合、例えば条件からの真の戻り値に到達しない場合、待機は timeout error と呼ばれるエラー/例外をスロー/発生させます。

オプション

待機条件は、ニーズに合わせてカスタマイズできます。 成功した条件にヒットしないことに対するペナルティは高額になる可能性があるため、デフォルトのタイムアウトの全範囲を待つ必要がない場合があります。

WebDriverWaitに引数を渡してタイムアウトをオーバーライドできます。

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")))
  

期待される条件

DOMと指示を同期しなければならないことは非常に一般的であるため、ほとんどのクライアントには事前に定義された一連の _期待される条件_もあります。 名前から明らかなように、これらは頻繁な待機操作に対して事前定義されている条件です。

異なる言語バインディングで利用可能な条件は異なりますが、これは少数の抜粋したリストです。

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

各クライアントバインディングのAPIドキュメントを参照して、予想される条件の完全なリストを見つけることができます。

暗黙的な待機

暗黙的な待機 と呼ばれる明示的な待機とは異なる2番目の種類の待機があります。 暗黙的に待機することにより、WebDriverは 何か 要素を見つけようとするときに特定の期間DOMをポーリングします。 これは、Webページ上の特定の要素がすぐに利用できず、ロードに時間がかかる場合に役立ちます。

要素の表示を暗黙的に待機することはデフォルトで無効になっており、セッションごとに手動で有効にする必要があります。 明示的な待機と暗黙的な待機を混在させると、意図しない結果、すなわち、要素が利用可能または条件が真であっても、最大時間スリープする待機が発生します。

警告 : 暗黙的な待機と明示的な待機を混在させないでください。 これを行うと、予測できない待機時間が発生する可能性があります。 たとえば、10秒の暗黙的な待機と15秒の明示的な待機を設定すると、20秒後にタイムアウトが発生する可能性があります。

暗黙的な待機は、1つまたは複数の要素がすぐに利用できない場合にそれらを見つけようとするときにWebDriverにDOMを一定時間ポーリングするように指示することです。 デフォルト設定は0で、無効を意味します。 設定すると、セッションの存続期間中、暗黙的な待機が設定されます。

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()

val myDynamicElement = driver.findElement(By.id("myDynamicElement"))
  

FluentWait

FluentWaitインスタンスは、条件を待機する最大時間を定義します。 状態を確認する頻度も同様です。

ユーザーは、ページ上の要素を検索するときのNoSuchElementExceptionなど、待機中に特定の種類の例外を無視するように待機を構成できます。

// 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")) }
  

5 - Web要素

DOM内の要素オブジェクトの識別と操作

ほとんどの人のSeleniumコードの大部分は、Web要素の操作に関連しています。

5.1 - File Upload

The file upload dialog could be handled using Selenium, when the input element is of type file. An example of it, could be found on this web page- https://the-internet.herokuapp.com/upload We will require to have a file available with us, which we need to upload. The code to upload the file for different programming languages will be as follows -

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()

                driver.Navigate().GoToUrl("https://the-internet.herokuapp.com/upload");
                driver.FindElement(By.Id("file-upload")).SendKeys("selenium-snapshot.jpg");
                driver.FindElement(By.Id("file-submit")).Submit();
                if (driver.PageSource.Contains("File Uploaded!"))
                {
                    Console.WriteLine("file uploaded");
                }
                else
                {
                    Console.WriteLine("file not uploaded");
                }
                driver.Quit();

            }

            }
}

  
require 'selenium-webdriver'
driver = Selenium::WebDriver.for :chrome
driver.get("https://the-internet.herokuapp.com/upload")
driver.find_element(:id,"file-upload").send_keys("selenium-snapshot.jpg")
driver.find_element(:id,"file-submit").submit()

if driver.page_source().include? "File Uploaded!"
  puts "file upload success"
else
  puts "file upload not successful"
end

  
import {Builder,By} from "selenium-webdriver"


let driver = await new Builder().forBrowser('chrome').build()
await driver.get("https://the-internet.herokuapp.com/upload");

await driver.findElement(By.id("file-upload")).sendKeys("selenium-snapshot.jpg")
await driver.findElement(By.id("file-submit")).submit()

driver.getPageSource().then(result => {
    if (result.indexOf("File Uploaded!")){
        console.log("file upload success")
    }else {
        console.log("file upload not successful")
    }
})
  
import org.openqa.selenium.By
import org.openqa.selenium.chrome.ChromeDriver

fun main() {
    val driver = ChromeDriver()
    driver.get("https://the-internet.herokuapp.com/upload")
    driver.findElement(By.id("file-upload")).sendKeys("selenium-snapshot.jpg")
    driver.findElement(By.id("file-submit")).submit()
    if(driver.pageSource.contains("File Uploaded!")) {
        println("file uploaded")
    }
    else{
        println("file not uploaded")
    }
}

So the above example code helps to understand how we can upload a file using Selenium.

5.2 - 要素を探す

DOM内の1つ以上の特定の要素を識別する方法

ロケーターは、ページ上の要素を識別する方法です。 これは、検索要素 メソッドに渡される引数です。

検出方法とは別にロケーターを宣言するタイミングと理由など、 ロケーターに関するヒントについては、 推奨されるテストプラクティス を確認してください。

要素選択の方法

WebDriverには標準のロケータが8種類あります。

ロケータ 詳細
class name class名に値を含む要素を探す (複合クラス名は使えない)
css selector CSSセレクタが一致する要素を探す
id id属性が一致する要素を探す
name name属性が一致する要素を探す
link text a要素のテキストが一致する要素を探す
partial link text a要素のテキストが部分一致する要素を探す
tag name タグ名が一致する要素を探す
xpath XPathと一致する要素を探す

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> 

<p>To know more about Selenium, visit the official page 
<a href ="www.selenium.dev">Selenium Official Page</a> 
</p>

</body>
</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']'))
  

相対ロケーター

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"))

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();
    }
}
}
from selenium import webdriver
from selenium.webdriver.common.by import By
from selenium.webdriver.common.keys import Keys
driver = webdriver.Firefox()

    # Navigate to url
driver.get("http://www.google.com")

    # Enter "webdriver" text and perform "ENTER" keyboard action
driver.find_element(By.NAME, "q").send_keys("webdriver" + Keys.ENTER)
using (var driver = new FirefoxDriver())
{
// Navigate to Url
driver.Navigate().GoToUrl("https://google.com");

// Enter "webdriver" text and perform "ENTER" keyboard action
driver.FindElement(By.Name("q")).SendKeys("webdriver" + Keys.Enter);
}
require 'selenium-webdriver'
driver = Selenium::WebDriver.for :firefox
begin
# Navigate to URL
driver.get 'https://google.com'

    # Enter "webdriver" text and perform "ENTER" keyboard action
driver.find_element(name: 'q').send_keys 'webdriver', :return

ensure
driver.quit
end
const {Builder, By, Key} = require('selenium-webdriver');

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

try {
// Navigate to Url
await driver.get('https://www.google.com');

    // Enter text "webdriver" and perform keyboard action "Enter"
    await driver.findElement(By.name('q')).sendKeys('webdriver', Key.ENTER);
}
finally {
await driver.quit();
}
})();
import org.openqa.selenium.By
import org.openqa.selenium.Keys
import org.openqa.selenium.firefox.FirefoxDriver

fun main() {
val driver = 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()
}
}

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;
import org.openqa.selenium.WebDriver;
import org.openqa.selenium.WebElement;
import org.openqa.selenium.chrome.ChromeDriver;

public class clear {
public static void main(String[] args) {
WebDriver driver = new ChromeDriver();
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 {
driver.quit();
}
}
}
from selenium import webdriver
from selenium.webdriver.common.by import By
driver = webdriver.Chrome()

    # Navigate to url
driver.get("http://www.google.com")
# Store 'SearchInput' element
SearchInput = driver.find_element(By.NAME, "q")
SearchInput.send_keys("selenium")
# Clears the entered text
SearchInput.clear()
using OpenQA.Selenium;

using System;

namespace SnipetProjectDelete
{
class Program
{
static void Main(string[] args)
{
IWebDriver driver = new ChromeDriver();
try
{
// Navigate to Url
driver.Navigate().GoToUrl(@"https://www.google.com");
// Store 'SearchInput' element
IWebElement searchInput = driver.FindElement(By.Name("q"));
searchInput.SendKeys("selenium");
// Clears the entered text
searchInput.Clear();
}
finally
{
driver.Quit();
}
}
}
}
require 'selenium-webdriver'
driver = Selenium::WebDriver.for :chrome
begin
# Navigate to URL
driver.get 'https://google.com'
# store 'search_input' element
search_input = driver.find_element(name: 'q')
search_input.send_keys('selenium')
# Clears the entered text
search_input.clear
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();
import org.openqa.selenium.By
import org.openqa.selenium.chrome.ChromeDriver
fun main() {
val driver =  ChromeDriver()
try {
// Navigate to Url
driver.get("https://www.google.com")
// Store 'searchInput' element
val searchInput = driver.findElement(By.name("q"))
searchInput.sendKeys("selenium")
// Clears the entered text
searchInput.clear()
} finally {
driver.quit()
}
}

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 - Web要素の検索

提供されたロケーターの値に基づいて要素を検索します。

Seleniumを使用する最も基本的な側面の1つは、操作する要素の参照を取得することです。 Seleniumは、要素を一意に識別するための多数の組み込みロケーター戦略を提供します。 非常に高度なシナリオでロケーターを使用する方法はたくさんあります。 このドキュメントの目的のために、このHTMLスニペットについて考えてみましょう。

<ol id="vegetables">
 <li class="potatoes"> <li class="onions"> <li class="tomatoes"><span>Tomato is a Vegetable</span></ol>
<ul id="fruits">
  <li class="bananas">  <li class="apples">  <li class="tomatoes"><span>Tomato is a Fruit</span></ul>

最初に一致する要素

多くのロケーターは、ページ上の複数の要素と一致します。 単数の find elementメソッドは、指定されたコンテキスト内で最初に見つかった要素への参照を返します。

DOM全体の評価

ドライバーインスタンスで要素の検索メソッドが呼び出されると、提供されたロケーターと一致するDOMの最初の要素への参照が返されます。 この値は保存して、将来の要素アクションに使用できます。 上記のHTMLの例では、クラス名が “tomatoes” の要素が2つあるため、このメソッドは “vegetables” リストの要素を返します。

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"))
  

DOMのサブセットの評価

DOM全体で一意のロケーターを見つけるのではなく、検索を別の検索された要素のスコープに絞り込むと便利なことがよくあります。 上記の例では、クラス名が “トマト” の2つの要素があり、2番目の要素の参照を取得するのは少し困難です。

1つの解決策は、目的の要素の祖先であり、不要な要素の祖先ではない一意の属性を持つ要素を見つけて、そのオブジェクトでfind要素を呼び出すことです。

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 and C#
WebDriverWebElement 、および ShadowRoot クラスはすべて、 ロールベースのインターフェイス と見なされる SearchContext インターフェイスを実装します。 ロールベースのインターフェイスを使用すると、特定のドライバーの実装が特定の機能をサポートしているかどうかを判断できます。 これらのインターフェースは明確に定義されており、責任の役割を1つだけ持つように努めています。

最適化されたロケーター

ネストされたルックアップは、ブラウザに2つの別々のコマンドを発行する必要があるため、最も効果的なロケーション戦略ではない可能性があります。

パフォーマンスをわずかに向上させるために、CSSまたはXPathのいずれかを使用して、単一のコマンドでこの要素を見つけることができます。 推奨されるテストプラクティスの章で、ロケーター戦略の提案を参照してください。

この例では、CSSセレクターを使用します。

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"))
  

一致するすべての要素

最初の要素だけでなく、ロケーターに一致するすべての要素への参照を取得する必要があるユースケースがいくつかあります。 複数の要素の検索メソッドは、要素参照のコレクションを返します。 一致するものがない場合は、空のリストが返されます。 この場合、すべてのfruitsとvegetableのリストアイテムへの参照がコレクションに返されます。

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"))
  

要素の取得

多くの場合、要素のコレクションを取得しますが、特定の要素を操作したいので、コレクションを繰り返し処理して、 必要な要素を特定する必要があります。

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

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

5.5 - Web要素に関する情報

要素について学ぶことができること。

特定の要素についてクエリできる詳細情報がいくつかあります。

表示されているかどうか

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()

要素が有効か

このメソッドは、接続された要素がWebページで有効または無効になっているかどうかを確認するために使います。 ブール値を返し、現在のブラウジングコンテキストで接続されている要素が 有効(enabled) になっている場合は True 、そうでない場合は false を返します。

//navigates to url
driver.get("https://www.google.com/");

//returns true if element is enabled else returns false
boolean value = driver.findElement(By.name("btnK")).isEnabled();
# Navigate to url
driver.get("http://www.google.com")

# Returns true if element is enabled else returns false
value = driver.find_element(By.NAME, 'btnK').is_enabled()
// Navigate to Url
driver.Navigate().GoToUrl("https://google.com");

// Store the WebElement
IWebElement element = driver.FindElement(By.Name("btnK"));

// Prints true if element is enabled else returns false
System.Console.WriteLine(element.Enabled);
# Navigate to url
driver.get 'http://www.google.com/'

# Returns true if element is enabled else returns false
ele = driver.find_element(name: 'btnK').enabled?
// Navigate to url
await driver.get('https://www.google.com');

// Resolves Promise and returns boolean value
let element =  await driver.findElement(By.name("btnK")).isEnabled();
//navigates to url
driver.get("https://www.google.com/")

//returns true if element is enabled else returns false
val attr = driver.findElement(By.name("btnK")).isEnabled()

要素が選択されているかどうか

このメソッドは、参照された要素が選択されているかどうかを判断します。 このメソッドは、チェックボックス、ラジオボタン、入力要素、およびオプション要素で広く使われています。

ブール値を返し、現在のブラウジングコンテキストで参照された要素が 選択されている 場合は True 、そうでない場合は false を返します。

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

//returns true if element is checked else returns false
boolean value = driver.findElement(By.cssSelector("input[type='checkbox']:first-of-type")).isSelected();
# Navigate to url
driver.get("https://the-internet.herokuapp.com/checkboxes")

# Returns true if element is checked else returns false
value = driver.find_element(By.CSS_SELECTOR, "input[type='checkbox']:first-of-type").is_selected()
// Navigate to Url
driver.Navigate().GoToUrl("https://the-internet.herokuapp.com/checkboxes");

// Returns true if element ins checked else returns false
bool value = driver.FindElement(By.CssSelector("input[type='checkbox']:last-of-type")).Selected;
# Navigate to url
driver.get 'https://the-internet.herokuapp.com/checkboxes'

# Returns true if element is checked else returns false
ele = driver.find_element(css: "input[type='checkbox']:last-of-type").selected?
// Navigate to url
await driver.get('https://the-internet.herokuapp.com/checkboxes');

// Returns true if element ins checked else returns false
let res = await driver.findElement(By.css("input[type='checkbox']:last-of-type")).isSelected();
//navigates to url

# Navigate to url
driver.get("https://www.example.com")

# Returns TagName of the element
attr = driver.find_element(By.CSS_SELECTOR, "h1").tag_name
// Navigate to Url
driver.Navigate().GoToUrl("https://www.example.com");

// Returns TagName of the element
string attr = driver.FindElement(By.CssSelector("h1")).TagName;
# Navigate to url
driver.get 'https://www.example.com'

# Returns TagName of the element
attr = driver.find_element(css: "h1").tag_name
// Navigate to URL
await driver.get('https://www.example.com');

6.2 - JavaScript アラート、プロンプトおよび確認

WebDriverは、JavaScriptが提供する3種類のネイティブポップアップメッセージを操作するためのAPIを提供します。 これらのポップアップはブラウザーによってスタイルが設定され、カスタマイズが制限されています。

アラート

これらの最も単純なものはアラートと呼ばれ、カスタムメッセージと、ほとんどのブラウザーでOKのラベルが付いたアラートを非表示にする単一のボタンを表示します。 ほとんどのブラウザーでは閉じるボタンを押すことで閉じることもできますが、これは常にOKボタンと同じことを行います。 アラートの例を参照してください

WebDriverはポップアップからテキストを取得し、これらのアラートを受け入れるか、または閉じることができます。

//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();

6.3 - クッキーの使用

Cookieは、Webサイトから送信され、コンピューターに保存される小さなデータです。 Cookieは、主にユーザーを認識し、保存されている情報を読み込むために使用されます。

WebDriver APIは、組み込みメソッドでCookieと対話するメソッドを提供します。

クッキーの追加

現在のブラウジングコンテキストにCookieを追加するために使用されます。 Cookieの追加では、一連の定義済みのシリアル化可能なJSONオブジェクトのみを受け入れます。 受け入れられたJSONキー値のリストへのリンクはこちらにあります。

まず、Cookieが有効になるドメインにいる必要があります。 サイトとの対話を開始する前にCookieを事前設定しようとしていて、ホームページが大きい場合/代替の読み込みに時間がかかる場合は、サイトで小さいページを見つけることです。(通常、たとえば http://example.com/some404page のような、404ページは小さいです。)

SameSite Cookie属性

これにより、ユーザーは、サードパーティのサイトによって開始されたリクエストとともに Cookieを送信するかどうかをブラウザに指示できます。 CSRF(クロスサイトリクエストフォージェリ)攻撃を防ぐために導入されました。

SameSite Cookie属性は、2つのパラメーターを命令として受け入れます。

Strict:

SameSite属性が Strict に設定されている場合、CookieはサードパーティのWebサイトによって 開始されたリクエストとともに送信されません。

Lax:

CookieのSameSite属性を Lax に設定すると、CookieはサードパーティのWebサイトによって 開始されたGETリクエストとともに送信されます。

Note: As of now this feature is landed in chrome(80+version), Firefox(79+version) and works with Selenium 4 and later versions.

6.4 - IFrame と Frame の操作

Frameは、同じドメイン上の複数のドキュメントからサイトレイアウトを構築する非推奨の手段となりました。 HTML5以前のWebアプリを使用している場合を除き、frameを使用することはほとんどありません。 iFrameは、まったく異なるドメインからのドキュメントの挿入を許可し、今でも一般的に使用されています。

FrameまたはiFrameを使用する必要がある場合、Webdriverを使用して同じ方法で作業できます。 iFrame内のボタンがある場合を考えてみましょう。ブラウザー開発ツールを使用して要素を検査すると、次のように表示される場合があります。

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

iFrameがなければ、次のようなボタンを使用してボタンをクリックします。

//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()
  

ただし、iFrameの外側にボタンがない場合は、代わりにno such elementエラーが発生する可能性があります。 これは、Seleniumがトップレベルのドキュメントの要素のみを認識するために発生します。 ボタンを操作するには、ウィンドウを切り替える方法と同様に、最初にFrameに切り替える必要があります。 WebDriverは、Frameに切り替える3つの方法を提供します。

WebElementを使う

WebElementを使用した切り替えは、最も柔軟なオプションです。好みのセレクタを使用してFrameを見つけ、それに切り替えることができます。

//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()
  

nameまたはIDを使う

FrameまたはiFrameにidまたはname属性がある場合、代わりにこれを使うことができます。 名前またはIDがページ上で一意でない場合、最初に見つかったものに切り替えます。

//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()
  

インデックスを使う

JavaScriptの window.frames を使用して照会できるように、Frameのインデックスを使用することもできます。

// 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)
  

Frameを終了する

iFrameまたはFrameセットを終了するには、次のようにデフォルトのコンテンツに切り替えます。

// 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 - ウィンドウとタブの操作

ウィンドウとタブ

ウィンドウハンドルの取得

WebDriverは、ウィンドウとタブを区別しません。 サイトが新しいタブまたはウィンドウを開く場合、Seleniumはウィンドウハンドルを使って連動します。 各ウィンドウには一意の識別子があり、これは単一のセッションで持続します。 次のコードを使用して、現在のウィンドウのウィンドウハンドルを取得できます。

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

ウィンドウまたはタブの切り替え

新しいウィンドウで開くリンクをクリックすると、新しいウィンドウまたはタブが画面にフォーカスされますが、WebDriverはオペレーティングシステムがアクティブと見なすウィンドウを認識しません。 新しいウィンドウで作業するには、それに切り替える必要があります。 開いているタブまたはウィンドウが2つしかなく、どちらのウィンドウから開始するかがわかっている場合、削除のプロセスによって、WebDriverが表示できる両方のウィンドウまたはタブをループし、元のウィンドウまたはタブに切り替えることができます。

ただし、Selenium 4には、新しいタブ(または)新しいウィンドウを作成して自動的に切り替える新しいAPI NewWindow が用意されています。

//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
with webdriver.Firefox() as driver:
    # Open URL
    driver.get("https://seleniumhq.github.io")

    # 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
Assert.AreEqual(driver.WindowHandles.Count, 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(wd => wd.WindowHandles.Count == 2);

//Loop through until we find a new window handle
foreach(string window in driver.WindowHandles)
{
    if(originalWindow != window)
    {
        driver.SwitchTo().Window(window);
        break;
    }
}
//Wait for the new tab to finish loading content
wait.Until(wd => wd.Title == "Selenium documentation");
  
    #Store the ID of the original window
original_window = driver.window_handle

    #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"))

  

新しいウィンドウ(または)新しいタブを作成して切り替える

新しいウィンドウ(または)タブを作成し、画面上の新しいウィンドウまたはタブにフォーカスします。 新しいウィンドウ(または)タブを使用するように切り替える必要はありません。 新しいウィンドウ以外に3つ以上のウィンドウ(または)タブを開いている場合、WebDriverが表示できる両方のウィンドウまたはタブをループして、元のものではないものに切り替えることができます。

注意: この機能は、Selenium 4以降のバージョンで機能します。

// 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)
  

ウィンドウまたはタブを閉じる

ウィンドウまたはタブでの作業が終了し、 かつ ブラウザーで最後に開いたウィンドウまたはタブではない場合、それを閉じて、以前使用していたウィンドウに切り替える必要があります。 前のセクションのコードサンプルに従ったと仮定すると、変数に前のウィンドウハンドルが格納されます。 これをまとめると以下のようになります。

//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)

  

ウィンドウを閉じた後に別のウィンドウハンドルに切り替えるのを忘れると、現在閉じられているページでWebDriverが実行されたままになり、 No Such Window Exception が発行されます。実行を継続するには、有効なウィンドウハンドルに切り替える必要があります。

セッションの終了時にブラウザーを終了する

ブラウザーセッションを終了したら、closeではなく、quitを呼び出す必要があります。

driver.quit();
driver.quit()
driver.Quit();
driver.quit
await driver.quit();
driver.quit()
  • Quitは、
    • そのWebDriverセッションに関連付けられているすべてのウィンドウとタブを閉じます
    • ブラウザーのプロセス
    • バックグラウンドのドライバーのプロセス
    • ブラウザーが使用されなくなったことをSelenium Gridに通知して、別のセッションで使用できるようにします(Selenium Gridを使用している場合)

quitの呼び出しに失敗すると、余分なバックグラウンドプロセスとポートがマシン上で実行されたままになり、後で問題が発生する可能性があります。

一部のテストフレームワークでは、テストの終了時にフックできるメソッドとアノテーションを提供しています。

/**
 * 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()
}
  

テストコンテキストでWebDriverを実行していない場合は、ほとんどの言語で提供されている try / finally の使用を検討して、例外がWebDriverセッションをクリーンアップするようにします。

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()
}
  

PythonのWebDriverは、pythonコンテキストマネージャーをサポートするようになりました。 withキーワードを使用すると、実行終了時にドライバーを自動的に終了できます。

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

# WebDriver will automatically quit after indentation

ウィンドウマネジメント

画面解像度はWebアプリケーションのレンダリング方法に影響を与える可能性があるため、WebDriverはブラウザーウィンドウを移動およびサイズ変更するメカニズムを提供します。

ウィンドウサイズの取得

ブラウザーウィンドウのサイズをピクセル単位で取得します。

//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
  

ウィンドウサイズの設定

ウィンドウを復元し、ウィンドウサイズを設定します。

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)

ウィンドウの位置を取得

ブラウザーウィンドウの左上の座標を取得します。

// 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

  
## ウィンドウの位置設定

選択した位置にウィンドウを移動します。

// 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)
    

ウィンドウの最大化

ウィンドウを拡大します。ほとんどのオペレーティングシステムでは、オペレーティングシステムのメニューとツールバーをブロックすることなく、ウィンドウが画面いっぱいに表示されます。

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

ウィンドウを最小化

現在のブラウジングコンテキストのウィンドウを最小化します。 このコマンドの正確な動作は、個々のウィンドウマネージャーに固有のものです。

ウィンドウを最小化すると、通常、システムトレイのウィンドウが非表示になります。

注:この機能は、Selenium 4以降のバージョンで機能します。

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

全画面ウィンドウ

ほとんどのブラウザーでF11を押すのと同じように、画面全体に表示されます。

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()

スクリーンショットの取得

現在のブラウジング コンテキストのスクリーンショットをキャプチャするために使います。
WebDriver エンドポイントの スクリーンショット は、 Base64 形式でエンコードされたスクリーンショットを返します。

6.6 - Virtual Authenticator

A representation of the Web Authenticator model.

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

Web applications can enable a public key-based authentication mechanism known as Web Authentication to authenticate users in a passwordless manner. Web Authentication defines APIs that allows a user to create a public-key credential and register it with an authenticator. An authenticator can be a hardware device or a software entity that stores user’s public-key credentials and retrieves them on request.

As the name suggests, Virtual Authenticator emulates such authenticators for testing.

Virtual Authenticator Options

A Virtual Authenticatior has a set of properties. These properties are mapped as VirtualAuthenticatorOptions in the Selenium bindings.

    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

It creates a new virtual authenticator with the provided properties.


  @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

Removes the previously added virtual authenticator.

    VirtualAuthenticatorOptions options = new VirtualAuthenticatorOptions()
            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

Creates a resident (stateful) credential with the given required credential parameters.

  public void testRemoveAuthenticator() {
    VirtualAuthenticatorOptions options = new VirtualAuthenticatorOptions();
    VirtualAuthenticator authenticator =
      ((HasVirtualAuthenticator) driver).addVirtualAuthenticator(options);
            byte[] credentialId = { 1, 2, 3, 4 };
            byte[] userHandle = { 1 };

            Credential residentCredential = Credential.CreateResidentCredential(
              credentialId, "localhost", base64EncodedPK, userHandle, 0);

Create Non-Resident Credential

Creates a resident (stateless) credential with the given required credential parameters.

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

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

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

Add Credential

Registers the credential with the authenticator.

      .setProtocol(VirtualAuthenticatorOptions.Protocol.U2F)
      .setHasResidentKey(true);

    VirtualAuthenticator authenticator = ((HasVirtualAuthenticator) driver).addVirtualAuthenticator(options);

    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);

Get Credential

Returns the list of credentials owned by the authenticator.

    VirtualAuthenticatorOptions options = new VirtualAuthenticatorOptions()
      .setProtocol(VirtualAuthenticatorOptions.Protocol.U2F)
      .setHasResidentKey(false);

    VirtualAuthenticator authenticator = ((HasVirtualAuthenticator) driver).addVirtualAuthenticator(options);

    byte[] credentialId = {1, 2, 3, 4};
    Credential nonResidentCredential = Credential.createNonResidentCredential(
      credentialId, "localhost", ec256PrivateKey, /*signCount=*/0);
    authenticator.addCredential(nonResidentCredential);

    List<Credential> credentialList = authenticator.getCredentials();
    Assertions.assertEquals(1, credentialList.size());

    Credential credential = credentialList.get(0);
            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 };

            Credential residentCredential = Credential.CreateResidentCredential(
              credentialId, "localhost", base64EncodedPK, userHandle, 0);

            ((WebDriver)driver).AddCredential(residentCredential);

            List<Credential> credentialList = ((WebDriver)driver).GetCredentials();

Remove Credential

            ((WebDriver)driver).AddVirtualAuthenticator(new VirtualAuthenticatorOptions());

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

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

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

            ((WebDriver)driver).RemoveCredential(credentialId);
      .setIsUserVerified(true);
    VirtualAuthenticator authenticator = ((HasVirtualAuthenticator) driver).addVirtualAuthenticator(options);

    byte[] credentialId = {1, 2, 3, 4};
    byte[] userHandle = {1};
    Credential residentCredential = Credential.createResidentCredential(
      credentialId, "localhost", rsaPrivateKey, userHandle, /*signCount=*/0);

    authenticator.addCredential(residentCredential);

Remove All Credentials

Removes all the credentials from the authenticator.

    Assertions.assertArrayEquals(rsaPrivateKey.getEncoded(), credential.getPrivateKey().getEncoded());
  }

  @Test
  public void testRemoveCredential() {
    VirtualAuthenticator authenticator =
      ((HasVirtualAuthenticator) driver).addVirtualAuthenticator(new VirtualAuthenticatorOptions());

    byte[] credentialId = {1, 2, 3, 4};
    Credential credential = Credential.createNonResidentCredential(
            ((WebDriver)driver).AddVirtualAuthenticator(new VirtualAuthenticatorOptions());

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

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

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

            ((WebDriver)driver).RemoveAllCredentials();

Set User Verified

Sets whether the authenticator will simulate success or fail on user verification.

    Assertions.assertEquals(0, authenticator.getCredentials().size());
  }
            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.

                .perform()

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();
    text_input = driver.find_element(By.ID, "textInput")
    ActionChains(driver)\
        .send_keys_to_element(text_input, "abc")\
        .perform()
            driver.FindElement(By.TagName("body")).Click();
            
            IWebElement textField = driver.FindElement(By.Id("textInput"));
            new Actions(driver)
    text_field = driver.find_element(id: 'textInput')
    driver.action
          .send_keys(text_field, 'Selenium!')
          .perform

Selenium v4.5.0

      const textField = await driver.findElement(By.id('textInput'))

      await driver.actions()
        .sendKeys(textField, 'abc')
        .perform()
        val textField = driver.findElement(By.id("textInput"))
        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)
                .sendKeys(textField, "Selenium!")
                .sendKeys(Keys.ARROW_LEFT)
                .keyDown(Keys.SHIFT)
                .sendKeys(Keys.ARROW_UP)
                .keyUp(Keys.SHIFT)
                .keyDown(cmdCtrl)
                .sendKeys("xvv")
                .keyUp(cmdCtrl)
                .perform();

        Assertions.assertEquals("SeleniumSelenium!", textField.getAttribute("value"));
    cmd_ctrl = Keys.COMMAND if sys.platform == 'darwin' else Keys.CONTROL

    ActionChains(driver)\

        .send_keys("xvv")\
        .key_up(cmd_ctrl)\
        .perform()

            var capabilities = ((WebDriver)driver).Capabilities;
            String platformName = (string)capabilities.GetCapability("platformName");

            String cmdCtrl = platformName.Contains("mac") ? Keys.Command : Keys.Control;

            new Actions(driver)

          .key_up(cmd_ctrl)
          .perform
      const cmdCtrl = platform.includes('darwin') ? Key.COMMAND : Key.CONTROL

      await driver.actions()
        .click(textField)
        .sendKeys('Selenium!')
        .sendKeys(Key.ARROW_LEFT)
        .keyDown(Key.SHIFT)
        .sendKeys(Key.ARROW_UP)

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()));

      await actions.press(Button.BACK).release(Button.BACK).perform()
        val mouse = PointerInput(PointerInput.Kind.MOUSE, "default mouse")

        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

There is no convenience method for this, it is just pressing and releasing mouse button 4

        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();
        val clickable = driver.findElement(By.id("clickable"))
        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.

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 Japanese. Do you speak Japanese? 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 Protocol

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

While Selenium 4 provides direct access to the Chrome DevTools Protocol (CDP), it is highly encouraged that you use the WebDriver Bidi APIs instead.

Many browsers provide “DevTools” – a set of tools that are integrated with the browser that developers can use to debug web apps and explore the performance of their pages. Google Chrome’s DevTools make use of a protocol called the Chrome DevTools Protocol (or “CDP” for short). As the name suggests, this is not designed for testing, nor to have a stable API, so functionality is highly dependent on the version of the browser.

WebDriver Bidi is the next generation of the W3C WebDriver protocol and aims to provide a stable API implemented by all browsers, but it’s not yet complete. Until it is, Selenium provides access to the CDP for those browsers that implement it (such as Google Chrome, or Microsoft Edge, and Firefox), allowing you to enhance your tests in interesting ways. Some examples of what you can do with it are given below.

Emulate Geo Location

Some applications have different features and functionalities across different locations. Automating such applications is difficult because it is hard to emulate the geo-locations in the browser using Selenium. But with the help of Devtools, we can easily emulate them. Below code snippet demonstrates that.

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/");
driver.quit();

        "accuracy": 100
        })
    driver.execute_cdp_cmd("Emulation.setGeolocationOverride", Map_coordinates)
    driver.get("<your site url>")

      ChromeDriver driver = new ChromeDriver();
      DevToolsSession devToolsSession = driver.CreateDevToolsSession();
      var geoLocationOverrideCommandSettings = new SetGeolocationOverrideCommandSettings();

      geoLocationOverrideCommandSettings.Latitude = 51.507351;
      geoLocationOverrideCommandSettings.Longitude = -0.127758;
      geoLocationOverrideCommandSettings.Accuracy = 1;

      await devToolsSession
        .GetVersionSpecificDomains<OpenQA.Selenium.DevTools.V87.DevToolsSessionDomains>()
        .Emulation
        .SetGeolocationOverride(geoLocationOverrideCommandSettings);

Override Device Mode

Using Selenium’s integration with CDP, one can override the current device mode and simulate a new mode. Width, height, mobile, and deviceScaleFactor are required parameters. Optional parameters include scale, screenWidth, screenHeight, positionX, positionY, dontSetVisible, screenOrientation, viewport, and displayFeature.

The following list of APIs will be growing as the Selenium project works through supporting real world use cases. If there is additional functionality you’d like to see, please raise a feature request.

Register Basic Auth

Some applications make use of browser authentication to secure pages. With Selenium, you can automate the input of basic auth credentials whenever they arise.

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')

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');

Network Interception

If you want to capture network events coming into the browser and you want manipulate them you are able to do it with the following examples.

    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!");
Currently unavailable in python due the inability to mix certain async and sync commands
require 'selenium-webdriver'

      request.url = uri.to_s
    end
    continue.call(request)
end

httpResponse.body = "sausages"
await driver.onIntercept(connection, httpResponse, async function () {
  let body = await driver.getPageSource()
  assert.strictEqual(body.includes("sausages"), true, `Body contains: ${body}`)
})
driver.get(url)
val driver = ChromeDriver()
val interceptor = new NetworkInterceptor(
      driver,
      Route.matching(req -> true)

    driver.get(appServer.whereIs("/cheese"))

    String source = driver.getPageSource()

8.3 - BiDirectional API (W3C compliant)

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

The following list of APIs will be growing as the WebDriver BiDirectional Protocol grows and browser vendors implement the same. Additionally, Selenium will try to support real-world use cases that internally use a combination of W3C BiDi protocol APIs.

If there is additional functionality you’d like to see, please raise a feature request.

8.3.1 - Browsing Context

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 - 色を扱う

テストの一部として何かの色を検証したい場合があります。 問題は、ウェブ上の色の定義が一定ではないことです。 色のHEX表現を色のRGB表現と比較する簡単な方法、または色のRGBA表現を色のHSLA表現と比較する簡単な方法があったらいいのではないでしょうか?

心配しないでください。解決策があります。: Color クラスです!

まず、クラスをインポートする必要があります。

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

これで、カラーオブジェクトの作成を開始できます。 すべての色オブジェクトは、色の文字列表現から作成する必要があります。 サポートされている色表現は、以下のとおりです。

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)')
  
// This feature is not implemented - Help us by sending a pr to implement this feature
  
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)")
  

Colorクラスは、 http://www.w3.org/TR/css3-color/#html4 で指定されているすべての基本色定義もサポートしています。

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')
  
// This feature is not implemented - Help us by sending a pr to implement this feature
  
private val BLACK = Color.fromString("black")
private val CHOCOLATE = Color.fromString("chocolate")
private val HOTPINK = Color.fromString("hotpink")
  

要素に色が設定されていない場合、ブラウザは “透明” の色の値を返すことがあります。 Colorクラスもこれをサポートしています。

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')
  
// This feature is not implemented - Help us by sending a pr to implement this feature
  
private val TRANSPARENT = Color.fromString("transparent")
  

レスポンスが正しく解析され、有効なColorオブジェクトに変換されることを認識して、要素を安全にクエリしてその色/背景色を取得できるようになりました。

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'))
  
// This feature is not implemented - Help us by sending a pr to implement this feature
  
val loginButtonColour = Color.fromString(driver.findElement(By.id("login")).getCssValue("color"))

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

そして、色オブジェクトを直接比較できます。

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)
  
// This feature is not implemented - Help us by sending a pr to implement this feature
  
assert(loginButtonBackgroundColour.equals(HOTPINK))
  

または、色を次の形式のいずれかに変換し、静的に検証することができます。

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)')
  
// This feature is not implemented - Help us by sending a pr to implement this feature
  
assert(loginButtonBackgroundColour.asHex().equals("#ff69b4"))
assert(loginButtonBackgroundColour.asRgba().equals("rgba(255, 105, 180, 1)"))
assert(loginButtonBackgroundColour.asRgb().equals("rgb(255, 105, 180)"))
  

色はもはや問題ではありません。

9.2 - 選択要素の操作

選択リストには、他の要素と比較して特別な動作があります。

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")

9.3 - ThreadGuard

このクラスは、Javaバインディングでのみ使用可能です。

ThreadGuardは、ドライバーが、それを作成した同じスレッドからのみ呼び出されることを確認します。 特に並行してテストを実行する場合のスレッドの問題は、不可解でエラーの診断が難しい場合があります。 このラッパーを使用すると、このカテゴリのエラーが防止され、発生時に例外が発生します。

次の例は、スレッドの衝突をシミュレートします。

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

  static {
    System.setProperty("webdriver.chrome.driver", "<Set path to your Chromedriver>");
  }

  //Thread-1 (id 24) is calling the same driver causing the clash to happen
  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();

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])
