java - webdrivermanager 是否支持 RemoteWebDriver (Selenium Grid)？

Question

我已经在我的 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，它失败了并且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);

它抛出以下异常。

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

1. 启动集线器和节点。您可以使用命令行 ( java -jar selenium-server-standalone-<version>.jar standalone ) 执行此操作，或在 WebDriverManager 的帮助下使用 Java 类来下载适当的驱动程序。在这里你可以找到一个 example使用 Chrome 和 Firefox 作为浏览器。
2. 运行您的测试，连接到 URL 的中心。这里还有一个example .
