linux – 未知错误：在ubuntu上执行Selenium UI测试用例时,DevToolsActivePort文件不存在错误

我有一个拥有UI的ubuntu服务器. U可以通过触发mvn test命令来执行测试用例.但问题是,当我从另一台机器通过终端ssh机器时,我得到以下错误 –

unkNown error: DevToolsActivePort file doesn't exist
  (Driver info: chromedriver=2.40.565383 (76257d1ab79276b2d53ee976b2c3e3b9f335cde7),platform=Linux 4.4.0-121-generic x86_64) (WARNING: The server did not provide any stacktrace @R_789_4045@ion)

Driver info: driver.version: ChromeDriver

但是如果我通过remmina远程机器然后执行该机器终端的相同命令,则相同的命令会成功启动chrome.

解决方法:

尝试运行没有sudo权限的selenium-server：

java -jar path / to / selenium-server-standalone.jar
