BiDirectional API (W3C compliant)

Page being translated from English to Portuguese. Do you speak Portuguese? 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 Portuguese. Do you speak Portuguese? 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.

        BrowsingContext browsingContext = new BrowsingContext(driver, WindowType.WINDOW);
Check code on GitHub

Open a new tab

Creates a new browsing context in a new tab.

        BrowsingContext browsingContext = new BrowsingContext(driver, WindowType.TAB);
Check code on GitHub

Use existing window handle

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

        String id = driver.getWindowHandle();
        BrowsingContext browsingContext = new BrowsingContext(driver, id);

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.

        BrowsingContext
                browsingContext =
                new BrowsingContext(driver, WindowType.WINDOW, driver.getWindowHandle());

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.

        BrowsingContext
                browsingContext =
                new BrowsingContext(driver, WindowType.TAB, driver.getWindowHandle());
Check code on GitHub 
        BrowsingContext browsingContext = new BrowsingContext(driver, WindowType.TAB);

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

        Assertions.assertNotNull(browsingContext.getId());
        Assertions.assertNull(info.getNavigationId());
        Assertions.assertTrue(info.getUrl().contains("/bidi/logEntryAdded.html"));
Check code on GitHub 
        BrowsingContext browsingContext = new BrowsingContext(driver, WindowType.TAB);

        NavigationResult info = browsingContext.navigate("https://www.selenium.dev/selenium/web/bidi/logEntryAdded.html",
                ReadinessState.COMPLETE);

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

Get browsing context tree

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

        String referenceContextId = driver.getWindowHandle();
        BrowsingContext parentWindow = new BrowsingContext(driver, referenceContextId);

        parentWindow.navigate("https://www.selenium.dev/selenium/web/iframes.html", ReadinessState.COMPLETE);

        List<BrowsingContextInfo> contextInfoList = parentWindow.getTree();

        Assertions.assertEquals(1, contextInfoList.size());
        BrowsingContextInfo info = contextInfoList.get(0);
        Assertions.assertEquals(1, info.getChildren().size());
        Assertions.assertEquals(referenceContextId, info.getId());
        Assertions.assertTrue(info.getChildren().get(0).getUrl().contains("formPage.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.

        String referenceContextId = driver.getWindowHandle();
        BrowsingContext parentWindow = new BrowsingContext(driver, referenceContextId);

        parentWindow.navigate("https://www.selenium.dev/selenium/web/iframes.html", ReadinessState.COMPLETE);

        List<BrowsingContextInfo> contextInfoList = parentWindow.getTree(0);

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

Get All Top level browsing contexts

        BrowsingContext window1 = new BrowsingContext(driver, driver.getWindowHandle());
        BrowsingContext window2 = new BrowsingContext(driver, WindowType.WINDOW);

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

        Assertions.assertEquals(2, contextInfoList.size());

Close a tab/window

        BrowsingContext window1 = new BrowsingContext(driver, WindowType.WINDOW);
        BrowsingContext window2 = new BrowsingContext(driver, WindowType.WINDOW);

        window2.close();

        Assertions.assertThrows(BiDiException.class, window2::getTree);

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.

            CompletableFuture<ConsoleLogEntry> future = new CompletableFuture<>();
            logInspector.onConsoleLog(future::complete);

            driver.get("https://www.selenium.dev/selenium/web/bidi/logEntryAdded.html");
