Unit Testing in Java: How Tests Drive the Code (The Morgan Kaufmann Series in Software Engineering and Programming) - Softcover

Introduces both the basic and advanced use of JUnit, a widely used Open Source framework for testing Java applications.

Unit Testing in Java
How Tests Drive the Code

Forewords by Erich Gamma and Frank Westphal

"This...is a practical introduction to using automated unit tests and the test-first approach in your day-to-day software development. The automation framework used...is JUnit. It is a small and simple framework for creating and managing tests. However, more is needed for successful development with unit tests. In fact, a developer has to be familiar with many different testing techniques, in particular when unit tests have to be created in the context of databases or distributed applications based on application servers. This book sheds light on these problems and is a highly welcome contribution to the field of automated unit testing."―Erich Gamma, Co-author of JUnit and Technical Director, Object Technology International

"This book brings together the knowledge that a number of pioneering extreme programmers wish they had when they started applying test-first programming five years ago. If you follow down that route, you will invariably run into testing problems. Even though you are writing your tests first, you will come to halt because you won't see how to test your code. That's natural. Actually, that's the perfect time to reflect. Or to pick up this book and read what Johannes tells us."―Frank Westphal, independent trainer and consultant

Programmers understand that if errors are found at the early stage of a project they can be removed faster and at less cost than at later stages. For a variety of reasons, however, testing has lagged behind in software development practice. Now, complex distributed systems and new software development techniques have brought a resurgent interest in testing. In this book Johannes Link gives clear guidance on how to make tests work for you, and shows how test-driven development works in practice.

Features
*Shows how the discovery and avoidance of software errors is a demanding and creative activity in its own right and can build confidence early in a project.
*Demonstrates how automated tests can detect the unwanted effects of small changes in code within the entire system.
*Discusses how testing works with persistency, concurrency, distribution, and web applications.
*Includes a discussion of testing with C++ and Smalltalk.
