BiDirectional functionality

BiDirectional means that communication is happening in two directions simultaneously. The traditional WebDriver model involves strict request/response commands which only allows for communication to happen in one direction at any given time. In most cases this is what you want; it ensures that the browser is doing the expected things in the right order, but there are a number of interesting things that can be done with asynchronous interactions.

This functionality is currently available in a limited fashion with the [Chrome DevTools Protocol] (CDP), but to address some of its drawbacks, the Selenium team, along with the major browser vendors, have worked to create the new WebDriver BiDi Protocol. This specification aims to create a stable, cross-browser API that leverages bidirectional communication for enhanced browser automation and testing functionality, including streaming events from the user agent to the controlling software via WebSockets. Users will be able to listen for and record or manipulate events as they happen during the course of a Selenium session.

Enabling BiDi in Selenium

In order to use WebDriver BiDi, setting the capability in the browser options will enable the required functionality:

options.setCapability("webSocketUrl", true);
options.enable_bidi = True
UseWebSocketUrl = true,
options.web_socket_url = true
Options().enableBidi();
options.setCapability("webSocketUrl", true);

This enables the WebSocket connection for bidirectional communication, unlocking the full potential of the WebDriver BiDi protocol.

Note that Selenium is updating its entire implementation from WebDriver Classic to WebDriver BiDi (while maintaining backwards compatibility as much as possible), but this section of documentation focuses on the new functionality that bidirectional communication allows. The low-level BiDi domains will be accessible in the code to the end user, but the goal is to provide high-level APIs that are straightforward methods of real-world use cases. As such, the low-level components will not be documented, and this section will focus only on the user-friendly features that we encourage users to take advantage of.

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

1 - WebDriver BiDi Logging Features

These features are related to logging. Because “logging” can refer to so many different things, these methods are made available via a “script” namespace.

Remember that to use WebDriver BiDi, you must enable it in Options. For more details, see Enabling BiDi

Console Message Handlers

Record or take actions on console.log events.

Add Handler

    driver.script.add_console_message_handler(log_entries.append)
    driver.script.add_console_message_handler { |log| log_entries << log }

Remove Handler

You need to store the ID returned when adding the handler to delete it.

    id = driver.script.add_console_message_handler(log_entries.append)
    driver.script.remove_console_message_handler(id)
    id = driver.script.add_console_message_handler { |log| log_entries << log }
    driver.script.remove_console_message_handler(id)

JavaScript Exception Handlers

Record or take actions on JavaScript exception events.

Add Handler

    driver.script.add_javascript_error_handler(log_entries.append)
    driver.script.add_javascript_error_handler { |error| log_entries << error }

Remove Handler

You need to store the ID returned when adding the handler to delete it.

    id = driver.script.add_javascript_error_handler(log_entries.append)
    driver.script.remove_javascript_error_handler(id)
    id = driver.script.add_javascript_error_handler { |error| log_entries << error }
    driver.script.remove_javascript_error_handler(id)

2 - WebDriver BiDi Network Features

These features are related to networking, and are made available via a “network” namespace.

The implementation of these features is being tracked here: #13993

Remember that to use WebDriver BiDi, you must enable it in Options. For more details, see Enabling BiDi

4 - Chrome DevTools 协议

使用 Selenium 操作 Chrome DevTools 协议的示例。 CDP 的支持是临时的,直到 WebDriver BiDi 实现为止。

许多浏览器提供“开发者工具”(DevTools),这是与浏览器集成的一组工具,开发人员可以使用它们来调试网页应用程序并探索网页的性能。Google Chrome 的开发者工具使用一种称为 Chrome DevTools 协议(简称 “CDP”)的协议。顾名思义,该协议并非为测试设计,也没有稳定的 API,因此功能很大程度上取决于浏览器的版本。

Selenium 正在致力于实现一种基于标准的、跨浏览器的、稳定的 CDP 替代方案,称为 [WebDriver BiDi]。在对该新协议的支持完成之前,Selenium 计划在适用的地方提供对 CDP 功能的访问。

在 Selenium 中使用 Chrome DevTools 协议

Chrome 和 Edge 提供了发送基本 CDP 命令的方法。 但对于需要双向通信的功能,这种方法无效。你需要知道在何时启用哪些域,以及域、方法和参数的确切名称和类型。

    Map<String, Object> cookie = new HashMap<>();
    cookie.put("name", "cheese");
    cookie.put("value", "gouda");
    cookie.put("domain", "www.selenium.dev");
    cookie.put("secure", true);
    ((HasCdp) driver).executeCdpCommand("Network.setCookie", cookie);
    cookie = {'name': 'cheese',
              'value': 'gouda',
              'domain': 'www.selenium.dev',
              'secure': True}

    driver.execute_cdp_cmd('Network.setCookie', cookie)
            var cookie = new Dictionary<string, object>
            {
                { "name", "cheese" },
                { "value", "gouda" },
                { "domain", "www.selenium.dev" },
                { "secure", true }
            };
            ((ChromeDriver)driver).ExecuteCdpCommand("Network.setCookie", cookie);
    driver.execute_cdp('Network.setCookie',
                       name: 'cheese',
                       value: 'gouda',
                       domain: 'www.selenium.dev',
                       secure: true)

为简化 CDP 的使用并提供对更高级功能的访问,Selenium 绑定会自动为最常见的域生成类和方法。
不过,CDP 方法和实现可能会因版本而异,因此你需要确保 Chrome 版本和 DevTools 版本相匹配。
Selenium 在任何时间点支持 Chrome 的最近三个版本,并且尽量同步发布以确保可以访问最新版本。

这种限制给一些绑定带来了额外的挑战,动态生成的 CDP 支持要求用户定期更新代码,以引用正确版本的 CDP。
在某些情况下,已创建了一个理想化的实现,它应该适用于任何版本的 CDP,而无需用户更改代码,但这并非总是可用。

关于如何在 Selenium 测试中使用 CDP 的示例可以在以下页面找到,但我们想提到一些常被引用但实际价值有限的例子:

  • 地理位置 ——几乎所有网站都使用 IP 地址来确定物理位置,因此设置模拟地理位置很少能达到预期效果。
  • 覆盖设备指标 ——Chrome 提供了一个很棒的 API 来在 Options 类中设置移动模拟,这通常比尝试使用 CDP 更优越。

While Selenium 4 provides direct access to the Chrome DevTools Protocol, these methods will eventually be removed when WebDriver BiDi implemented.

Basic authentication

Some applications make use of browser authentication to secure pages. It used to be common to handle them in the URL, but browsers stopped supporting this. With this code you can insert the credentials into the header when necessary

    Predicate<URI> uriPredicate = uri -> uri.toString().contains("herokuapp.com");
    Supplier<Credentials> authentication = UsernameAndPassword.of("admin", "admin");
    ((HasAuthentication) driver).register(uriPredicate, authentication);
        credentials = base64.b64encode("admin:admin".encode()).decode()
        auth = {'authorization': 'Basic ' + credentials}
        await connection.session.execute(connection.devtools.network.set_extra_http_headers(Headers(auth)))
            var handler = new NetworkAuthenticationHandler()
            {
                UriMatcher = uri => uri.AbsoluteUri.Contains("herokuapp"),
                Credentials = new PasswordCredentials("admin", "admin")
            };
            var networkInterceptor = driver.Manage().Network;
            networkInterceptor.AddAuthenticationHandler(handler);
            await networkInterceptor.StartMonitoring();
    driver.register(username: 'admin',
                    password: 'admin',
                    uri: /herokuapp/)

Network Interception

Both requests and responses can be recorded or transformed.

Response information

    try (NetworkInterceptor ignored =
        new NetworkInterceptor(
            driver,
            (Filter)
                next ->
                    req -> {
                      HttpResponse res = next.execute(req);
                      contentType.add(res.getHeader("Content-Type"));
                      return res;
                    })) {
            INetwork networkInterceptor = driver.Manage().Network;
            networkInterceptor.NetworkResponseReceived += (_, e)  =>
            {
                contentType.Add(e.ResponseHeaders["content-type"]);
            };
            await networkInterceptor.StartMonitoring();
    driver.intercept do |request, &continue|
      continue.call(request) do |response|
        content_type << response.headers['content-type']
      end
    end

Response transformation

    try (NetworkInterceptor ignored =
        new NetworkInterceptor(
            driver,
            Route.matching(req -> true)
                .to(
                    () ->
                        req ->
                            new HttpResponse()
                                .setStatus(200)
                                .addHeader("Content-Type", MediaType.HTML_UTF_8.toString())
                                .setContent(Contents.utf8String("Creamy, delicious cheese!"))))) {
            var handler = new NetworkResponseHandler()
            {
                ResponseMatcher = _ => true,
                ResponseTransformer = _ => new HttpResponseData
                {
                    StatusCode = 200,
                    Body = "Creamy, delicious cheese!"
                }
            };
            INetwork networkInterceptor = driver.Manage().Network;
            networkInterceptor.AddResponseHandler(handler);
            await networkInterceptor.StartMonitoring();
    driver.intercept do |request, &continue|
      continue.call(request) do |response|
        response.body = 'Creamy, delicious cheese!' if request.url.include?('blank')
      end
    end

                        req =
                            new HttpRequest(
                                HttpMethod.GET, req.getUri().replace("one.js", "two.js"));
                      }
                      completed.set(true);
                      return next.execute(req);
                    })) {
            var handler = new NetworkRequestHandler
            {
                RequestMatcher = request => request.Url.Contains("one.js"),
                RequestTransformer = request =>
                {
                    request.Url = request.Url.Replace("one", "two");

                    return request;
                }
            };
            INetwork networkInterceptor = driver.Manage().Network;
            networkInterceptor.AddRequestHandler(handler);
            await networkInterceptor.StartMonitoring();
    driver.intercept do |request, &continue|
      uri = URI(request.url)
      request.url = uri.to_s.gsub('one', 'two') if uri.path&.end_with?('one.js')
      continue.call(request)
    end
