Testing Extreme Programming is a practical tutorial that gives software builders a lucid understanding of this important aspect of development. This book demonstrates how testing is central to the XP project, clearly spelling out what testing should be done and when and how it should be performed. The authors teach by example, and readers will be able to improve their knowledge of the testing process by completing the book's exercises.

In addition, this book:

• Provides a general overview of the XP methodology

• Defines the roles of XP team members

• Shows how to write effective tests before coding begins

• Helps you avoid the traps and pitfalls that can derail software projects

• Sheds light on the important practice of refactoring and how it relates to testing

• Compares and contrasts manual and automated tests

Many software engineers have dismissed XP as a throw-out-the-rulebook, anything-goes technique. It isn't. As this book shows, XP is a deliberate and disciplined approach to software development. Many software engineers have reaped the benefits of this agile methodology because its emphasis on testing eliminates much of the risk inherent in software projects. XP helps developers produce software on time, under budget, and at a higher quality level. But you can't XP if you don't test. With this book as a guide, you will learn to embrace testing. A sound testing program is the engine that drives an XP project.
