我在 pom.xml 文件中更新了 WebDrivermanager 的依赖项。在我的本地运行代码时，如下所示，它似乎工作正常。

driver = new ChromeDriver(capability);

但是当我尝试使用 RemoteWebDriver 远程运行代码时，它失败并一直要求为浏览器添加二进制文件

URL remote_grid = new URL("http://" + seleniumHub + ":" + seleniumHubPort + "/wd/hub");
driver = new RemoteWebDriver(remote_grid, capability);

它抛出异常。

事实上，WebDriverManager 可以帮助设置 Selenium Grid。该过程如下：

  1. 启动集线器。您可以使用命令行 ( ) 执行此操作，也可以使用本示例java -jar selenium-server-standalone-<version>.jar -role hub中的 Java 类。
  2. 在集线器中注册节点。这是 WebDriverManager 提供帮助的地方，因为它会下载正确的二进制文件，并使用该二进制文件注册节点。在这里您可以找到一个使用 Chrome 作为浏览器的示例。
  3. 运行测试，连接到 URL 的集线器。这里再举一个例子。
