Jenkins and Seleniumhq configuration

Question

I'm trying to set up a simple Selenium test in Jenkins. My OS is Debian GNU/Linux 6.0.7 (squeeze), desktop version (64-bit). I uninstalled the supplied browser iceweasel and intalled Firefox with aptitude. The firefox version is "20.0". I also have Google Chrome installed. I can run Firefox by writing "firefox" in a terminal window. Jenkins is installed with aptitude.

So, I have installed a plugin in Jenkins called Seleniumhq. These are my settings:

I then receive an error in the Jenkins console when I try to build:

I also tried to put this in the browser field: *firefox/usr/bin/firefox I think firefox is installed there (i ran "locate firefox"). That config renders another error msg:

...
HTML suite exception seen:
java.lang.RuntimeException: Browser not supported: *firefox/usr/bin/firefox

*firefox2

*piiexplore
*firefoxchrome
*opera

....

Does anybody have ideas about how to fix this? Thanks!

Edit

I changed the browser settings to this: *firefox /opt/firefox/firefox (with a space between) Now it seems FIrefox can be found, but I receive another error:

Answer 1

Well, I found a good tutorial that turned out to be useful. One important thing is to start a virtual X window on a server where Selenium can start the browser in to run your tests (Xvfb). And in Jenkins the server should be entered just like "*firefox".

Answer 2

You should try to run the commandline from a shell and see what happen. It's certainly a problem linked to the default profile used by the firefox instanciated by selenium.

In my case the problem was that firefox was starting by displaying the tabs that could be restored.

You can also try to create a specific profile : firefox -p or firefox -ProfileManager

then use this dedicated profile using command line parameter :
-firefoxProfileTemplate /home/userXXX/.mozilla/firefox/ljhyckqd.Selenium

java.lang.RuntimeException: Browser not supported: *firefox/usr/bin/firefox

Wrong syntax. try *firefox or *firefox [insert directory]
