The definitive guide, not just for JUnit, but unit testing in general.
JUnit is the leading Java unit testing framework and its version 4.8 significantly improves the Java development process. Designed for productivity, it has extensions for newer application styles—like Ajax and HTML-based presentation layers—and for application frameworks like EJB and OSGi.
JUnit in Action, Second Edition is an entirely revised and up-to-date guide to unit testing Java applications. It provides techniques for solving real-world problems such as using mocks for testing isolation, in-container testing for Java EE and database applications, and test automation. In an example-driven style, it covers JUnit 4.8 innovations such as the new annotations that simplify test writing, improved exception handling, and the new assertion methods. Along the way, you'll learn to integrate JUnit with other important open source frameworks and tools.
