Ryan has some excellent railscasts about testing:

• http://railscasts.com/tags/7

I recommend you start there. He has a very easy to follow style, and is a great teacher for new users and old users alike.

You could also take a look at RailsGuides' guide on testing in Rails:

http://guides.rubyonrails.org/testing.html

and various testing framework options here:
