在jenkins CI服务器上运行selenium webdriver/testng headless测试时出错

Question

我正在使用testNG框架和ANT任务运行Selenium测试。测试在我的windows机器上运行良好。。然后，我将其部署到我的Jenkins CI服务器上，并为无头运行测试进行必要的配置：

>

在运行jenkins（CentOS）的服务器上安装了vnc服务器

为jenkins安装了Xvnc插件，并在我的作业配置中启用了“在构建期间运行Xvnc”

然而，我得到以下错误-任何帮助？我已经搜索了网络，但找不到解决方案："org.openqa.selenium.firefox.NotConnectedExcema：无法连接到主机127.0.0.1端口7055后45000毫秒。火狐控制台”

这通常是由于FF和WD版本不兼容造成的。因此，仔细检查您使用的版本是否正确是有意义的。
