RSpec and Rails

While being all convinced of and impressed with all the advantages of developing with RSpec, cucumber and autotest, I have yet to find the time to actually start doing it. And there is not that much information out there (the bigger pieces probably being the screencasts on peepcode.com). I will try and document some of the more interesting findings as a convert. Right now, my rails project has reached its first milestone and is (or appears to be) functionally stable. Even if this was the case (which I do not really believe), keeping it that way would be worth writing tests.
