At the Forge - RSpec for Controllers

More on RSpec's “outside-in” approach to testing.

RSpec's “outside-in” approach to testing takes a bit of getting used to, but I increasingly have found it to be a method that forces me to think harder about my code, as well as about my testing strategy. That said, I'm not sure if I really have a strong preference for RSpec over similar BDD-style tools, such as Shoulda, which works with Ruby's traditional Test::Unit system. The bottom line is that you should try to include as much automated testing as possible in any software you design—not only because it will benefit your users, but also because it will benefit you as a developer.
