What tools are in your Test toolbox?

I'm curious about what tool are the people using for testing

Im currently using Rspec (for my Google summer of Code) and JUnit+XMLUnit+CruiseControl for my employer, yes I still woking with Java, no one want to hire my Ruby-fu services :frowning:

Im trying to learn all I can about testing methods, patterns and tools. I have some questions about who is using and about when/when-not to use this tools:

* Fitnesse, * autozen * CruiseControl.rb * testing secret tool? tell us your secrets * Watir * Selenium
