Test driven development is a proven technique that will help you write well tested and well designed code, but it takes some practice.
Here are some sample projects that you can work through to get some practice, along with my completed solutions so that you can see how I did it (not that my way is the only right way, of course).
If you’re in the Columbus, OH area and you want me to come give my TDD talk (which these samples came from), send me an email and let me know and we’ll work something out.
