The how and why of Rails unit testing
Kevin Clark has posted [an in-depth blog post on why unit testing is important, and the best way to go about it](http://glu.ttono.us/articles/2005/10/29/why-and-how-ruby-and-rails-unit-testing).
> One thing I love about Ruby is the built in unit tests. As someone who is working to use better developing methodologies, having unit testing avaliable with no effort makes it that much easier to try out things like Test Driven Development. Unit testing also has an important place in Rails development.
There are plenty of code examples and a step-by-step process of running a test. Very helpful.
