Automatic Unit Testing and Code Analysis

Hi

Does anybody know a good and powerful (yet simple of course) solution
to automatically run rails test (unit and functional) let's say every
night? I've stumbled upon 'CruiseControl' (http://
cruisecontrol.sourceforge.net/) and think this tool might do the job.
Any better ideas?

Cheers,
phibo

I've used cruisecontrol.rb (http://cruisecontrolrb.thoughtworks.com/),
but there are others. The magic term to google for is continuous
integration (and you probably want to run closer to every commit
rather than every night)
