A fantastic, definitive guide. It will boost your productivity and deployment effectiveness.
Effective Unit Testing is written to show how to write good tests—tests that are concise and to the point, expressive, useful, and maintainable. Inspired by Roy Osherove's bestselling The Art of Unit Testing, this book focuses on tools and practices specific to the Java world. It introduces you to emerging techniques like behavior-driven development and specification by example, and shows you how to add robust practices into your toolkit.

Changed the way I look at the Java development process. Highly recommended.
A common sense approach to writing high quality code.
Extremely useful, even if you write .NET code.
If unit tests are a nightmare for you, read this book!
