5.0

This is a book I plan on strongly recommending to other developers. Jay Fields presents his strategy for testing and his definition of a unit test. The book starts with some marginal unit tests and slowly improves them. I found myself feeling uncomfortable with the initial version of the tests and it was rewarding seeing the tests improve and having that uncomfortable feeling disappear.

Why do you write tests? What do you try to get out of testing? How do you make failing tests useful? By the time you finish this book you should have a been driven to think about those questions and more. Even it you don't agree with Jay's approach this book will make you think.

You should read this book.
