I just got this book the other day and I am on chapter 5. I was looking for some ideas for NUnit and so far the book looks good. I am mainly looking to see if I am missing anything about NUnit so that I can get better with it. Obviously I want to learn more about TDD also. So far I like it.
I also bought Extreme Programming adventures in C# from MS Press with the TDDbook. I am kind of reading them both at the same time since they are related. The XP book is excellent. I started with the TDD book but just happend to read the intro to the XP book and the author, Ron Jeffries, just hooked me right away. I can't put the XP book down!
I am always looking for ways to improve my coding habits. I hope that between these two books I will have the same religious experience I had after I read Code Complete.
