运行我的测试用例时,任何我的测试程序都尝试启动firefox,我得到了错误.我正在使用robotframework,Selenium2Library和python 2.7.

1Login   [ WARN ] Keyword 'Capture Page Screenshot' could not be run on failure: No browser is open

WebDriverException: Message: 'The browser appears to have exited before we could connect. The output was: Error: no display specified\n'

我的CentOS服务器上有Xwindows.我用firefox安装了yum.我的firefox安装在firefox: /usr/bin/firefox /usr/lib64/firefox /usr/share/man/man1/firefox.1.gz

这有什么不对？有没有人有类似的经历？任何参考或建议？谢谢

编辑:

结果,我运行演示后.

Selenium需要显示,而Linux没有显示,你需要下载虚拟显示(xvnc/xvfb).然后启动虚拟显示服务器和export显示器.

然后它应该工作

它解决了.细节是:第一次启动vncserver(例如`vncserver:1`).第二组`DISPLAY`(例如`DISPLAY =:1`).第三个更改目录到我的项目(例如`cd/path/to/my/project`).第四次执行我的项目(例如`pybot··········`).第5次杀死vncserver(例如`vncserver -kill:1`). (2认同)
