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.

1 - Browsing Context

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

This section contains the APIs related to browsing context commands.

Open a new window

Creates a new browsing context in a new window.

Open a new tab

Creates a new browsing context in a new tab.

    void testCreateAWindowWithAReferenceContext() {

Use existing window handle

Creates a browsing context for the existing tab/window to run commands.

Open a window with a reference browsing context

A reference browsing context is a top-level browsing context. The API allows to pass the reference browsing context, which is used to create a new window. The implementation is operating system specific.

Open a tab with a reference browsing context

A reference browsing context is a top-level browsing context. The API allows to pass the reference browsing context, which is used to create a new tab. The implementation is operating system specific.

    void testCreateATabWithAReferenceContext() {
        BrowsingContext
                browsingContext =
        NavigationResult info = browsingContext.navigate("https://www.selenium.dev/selenium/web/bidi/logEntryAdded.html");

        Assertions.assertNotNull(browsingContext.getId());
        Assertions.assertNull(info.getNavigationId());

Get browsing context tree

Provides a tree of all browsing contexts descending from the parent browsing context, including the parent browsing context.

                ReadinessState.COMPLETE);

        Assertions.assertNotNull(browsingContext.getId());
        Assertions.assertNull(info.getNavigationId());
        Assertions.assertTrue(info.getUrl().contains("/bidi/logEntryAdded.html"));
    }

Get browsing context tree with depth

Provides a tree of all browsing contexts descending from the parent browsing context, including the parent browsing context upto the depth value passed.

        Assertions.assertEquals(1, contextInfoList.size());
        BrowsingContextInfo info = contextInfoList.get(0);
        Assertions.assertEquals(1, info.getChildren().size());
        Assertions.assertEquals(referenceContextId, info.getId());

Get All Top level browsing contexts


        Assertions.assertEquals(1, contextInfoList.size());
        BrowsingContextInfo info = contextInfoList.get(0);
        Assertions.assertNull(info.getChildren()); // since depth is 0

Close a tab/window

        BrowsingContext window2 = new BrowsingContext(driver, WindowType.WINDOW);

        List<BrowsingContextInfo> contextInfoList = window1.getTopLevelContexts();

This section contains the APIs related to logging.

Listen to console.log events

Listen to the console.log events and register callbacks to process the event.

    }

    @AfterEach
    public void cleanup() {
        driver.quit();
    }

    @Test
            const inspector = await LogInspector(driver)
            await inspector.onConsoleEntry(function (log) {
              logEntry = log
            })
    
            await driver.get('https://www.selenium.dev/selenium/web/bidi/logEntryAdded.html')
            await driver.findElement({ id: 'consoleLog' }).click()
            
            assert.equal(logEntry.text, 'Hello, world!')
            assert.equal(logEntry.realm, null)
            assert.equal(logEntry.type, 'console')
            assert.equal(logEntry.level, 'info')
            assert.equal(logEntry.method, 'log')
            assert.equal(logEntry.stackTrace, null)
            assert.equal(logEntry.args.length, 1)

Listen to JS Exceptions

Listen to the JS Exceptions and register callbacks to process the exception details.

            Assertions.assertEquals("Error: Not working", logEntry.getText());
            Assertions.assertEquals("javascript", logEntry.getType());
            Assertions.assertEquals(LogLevel.ERROR, logEntry.getLevel());
        }
    }

    @Test
    void testListenToJavascriptErrorLog()
        const inspector = await LogInspector(driver)
        await inspector.onJavascriptException(function (log) {
            logEntry = log
        })

        await driver.get('https://www.selenium.dev/selenium/web/bidi/logEntryAdded.html')
        await driver.findElement({ id: 'jsException' }).click()

        assert.equal(logEntry.text, 'Error: Not working')
        assert.equal(logEntry.type, 'javascript')
        assert.equal(logEntry.level, 'error')

Listen to JS Logs

Listen to all JS logs at all levels and register callbacks to process the log.

            Assertions.assertEquals("console", logEntry.getType());
            Assertions.assertEquals("log", logEntry.getMethod());
            Assertions.assertNull(logEntry.getStackTrace());
        }
