How to change the directory for rostest log files?

edit

Hi everyone, my question is if it is possible to change the directory where rostest saves the test results and if so how it is done. The intention behind this is that I want an automated testing system embedded into jenkins. Right now, rostest saves to a hidden directory in my home directory but as jenkins is an online tool and my project is distributed I want the results to be saved on my server.

Some additional information: I have ros fuerte running on my PC (and on the server too, but I'm not sure since I am not the owner...).

Thanks in advance!
