A unit testing Example
Whether you are in the TDD camp or not, It goes without saying that unit testing is a very powerful way to ensure that your code is supposed to do what it is supposed to do. I never really got into TDD because by the time I had started to learn about it, I had already started to learn other patterns and techniques to design a losely coupled application. Afterall, the biggest benefit of TDD seems to be design. Regardles of the approach, testing our code is just a core part of software development.
