linux - 在 LInux 上使用 firefox 运行 selenium 测试

Question

Linux Ubuntu火狐 43 Selenium 2.53.1

我安装了 Xvfb 然后我做了这样的事情

Xvfb :77 -ac

和

export DISPLAY=:77

然后我检查 firefox 是否在 linux 上运行($firefox)-> 启动时没有错误，并保持运行直到我用 Control-C 杀死它

现在我尝试使用 Jenkins 开始我的 selenium 测试。我指示我的 DISPLAY 但是当我运行测试时我得到:

org.openqa.selenium.firefox.NotConnectedException:45000 毫秒后无法连接到端口 7055 上的主机 127.0.0.1。 Firefox 控制台输出:

谁能告诉我这里发生了什么？如何解决这个问题呢？它在 Windows 上运行良好——我的意思是 ff 43 和 selenium 2.53.1

Answer 1

启动时检查 X 虚拟帧缓冲区的参数。我觉得问题就出在这里。对我来说它有效，我按照 headless execution of selenium tests in Jenkins 一步步完成的博文。
