当我尝试使用 Selenium Grid 在 "Linux/XP/etc" 平台上执行时，我的测试失败了

Question

我是这个 Selenium 网格的新手。我的节点默认在 Win10 平台上注册。因此它可以毫无问题地执行脚本。但是当我尝试在 Win10 以外的运行上时，它失败了。有人可以帮我解决这个问题吗？我查看了互联网上所有可用的解决方案，但我无法解决它。

代码

  baseURL = "http://demo.guru99.com/test/guru99home/";
         nodeURL = "http://192.168.1.4:4444/wd/hub";
         ChromeOptions options=new ChromeOptions();
         DesiredCapabilities cap=DesiredCapabilities.chrome();
         cap.setPlatform(Platform.LINUX);
         options.merge(cap);
         driver = new RemoteWebDriver(new URL(nodeURL), options);

错误

如果我需要为必须添加这些功能的其他平台添加功能。

这个解决了我的问题。

java -jar "C:\Users\DELL\Desktop\Selenium Grid\selenium-server-standalone-3.141.5.jar" -role node -hub http://*.*.*.*:PortNumber/grid/register -port 5557 -browser "browserName=chrome,platform=LINUX"

注意：请将您的 IP 地址替换为“*”

并检查节点 URL 端口号。

当我尝试使用 Selenium Grid 在 "Linux/XP/etc" 平台上执行时，我的测试失败了
