Selenium在Ubuntu上启动Firefox时挂起 [英] Selenium hangs when launching Firefox on Ubuntu
问题描述
我的Jenkins安装在Ubuntu虚拟机中运行。
在jenkins selenium设置发生了一些问题（源于jenkins运行的用户权限）之后，切换到从命令行运行命令，看看发生了什么。我的目标是让测试在这里运行，然后在Jenkins中运行。
下面是我正在使用和看到的命令和响应。 >

在这个问题之前，我哈哈d Firefox配置文件的一个问题，我使用我在这里回答的方法修复了这个问题：
<使用应用程序菜单中的快捷方式启动Firefox，并在命令行上输入'firefox'即可打开Firefox。
我尝试添加完整路径到Firefox应用程序，以许多方式：
- 在命令'... * firefox /usr/lib/firefox-3.6.20 / firefox.sh ...导致无法找到HTML Suite文件：/ home / resn / http：/google.com： - 它似乎得到了与下一个参数混合的Firefox路径
-
在命令中，没有空格...firefox / usr / lib / firefox-3.6.20 / firefox.sh ... b
$ b
HTML套件异常情况：
java.lang.RuntimeException：浏览器不支持：* firefox / usr / lib / firefox-3.6.20 / firefox.sh
支持的浏览器包括：
* firefox
- 在grid_configuration.yml'... browser：* firefox /usr/lib.firefox-3.6.20/firefox.sh。这并没有什么影响。
此外，由于进程只是挂起，并没有真正的失败，日志文件（
$ b 任何想法，提示或调试建议都将非常受欢迎！解决方案这个问题似乎是在无头环境下运行的。如果你没有窗口来渲染你的浏览器，它会挂起。你可以通过在你的机器上粘贴相同的命令来测试它，而是使用ssh -X me@server.com
我发现了这个文档要解决这个问题：

My end goal is to have Selenium running 'within' Jenkins.
My Jenkins installation runs within an Ubuntu virtual machine.
After some issues with the jenkins selenium setup (stemming from permissions for the user that jenkins runs under) I switched to running the command from the command line to see what was happening. My aim is to get the test running here, and then to get it working within Jenkins.
Here's the command and responses I'm currently using and seeing.
resn@resn-VirtualBox:~$ sudo java -jar /var/lib/jenkins/tools/selenium/selenium-server.jar -htmlSuite *firefox http://google.com "/var/lib/jenkins/jobs/Selenium setup test/workspace/tests/test-testsuite.html" "/var/lib/jenkins/jobs/Selenium setup test/workspace/results/results.html" -log=/tmp/selenium.log -debug=true -firefoxProfileTemplate "/home/resn/.mozilla/firefox/6f2um01h.Selenium"

The Ubuntu virtual machine is not a headless instance, so AFAIK I don't need to install xvfb (as is mentioned in some blog posts on the same topic).
Previous to this issue, I had an issue with Firefox profiles, which I fixed using the approach I answered with here : Jenkins can't launch selenium tests (Timed out waiting for profile to be created)
Firefox opens fine when launched using the shortcut within the Applications menu, and from just entering 'firefox' on the command line.
I've tried adding the full path to the Firefox application, in numerous ways :
- In the command '... *firefox /usr/lib/firefox-3.6.20/firefox.sh ..." Which results in "Can't find HTML Suite file:/home/resn/http:/google.com:" - it seems to get the firefox path mixed up with the next parameter
In the command, without a space '... "firefox/usr/lib/firefox-3.6.20/firefox.sh ...' Which results in
"HTML suite exception seen:
java.lang.RuntimeException: Browser not supported: *firefox/usr/lib/firefox-3.6.20/firefox.sh
Supported browsers include:
*firefox"
- In grid_configuration.yml ' ... browser: "*firefox /usr/lib.firefox-3.6.20/firefox.sh". Which didn't have any impact.
Also, because the process just hangs, and doesn't actually fail, the log file (/tmp/selenium.log) isn't created.
Any ideas, tips or debugging suggestions would be very welcome!
解决方案 The problem seems to be when running in a headless environment. If you don't have a window for it to render your browser in, it will hang. You can test this by pasting the same command when you ssh into your machine, but instead do ssh -X me@server.com
I found this documentation on what you can do to fix this:
