Praise for the First Edition

The definitive how-to manual for unit testing Java EE components. Pick up one of the other books if you’re looking for something more motivational, but when you’re ready to sit down and bang out some code, you’ll want this book at your side.

I would definitely recommend JUnit in Action for anyone interested in testing their code.... It is a book that flows nicely, and offers a great mix of technology theory and how to put it all into practice.

An essential guide for intermediate level Java programmers who want to learn how to build Java EE applications properly...clear, simple and fun...the best I have seen thus far.... The book actually goes into detail about using mock objects and stubs, further expanding your understanding of basic software design.... I highly recommend it.

Not a JUnit tutorial, it covers JUnit in depth. It also explains the importance of JUnit in the context of software development process. This well-edited book is highly recommended both for the beginner and advanced users of JUnit.

With a number of Manning books I can see myself start to think differently about problems and so I end up being a better developer; JUnit in Action was like that for me. At first it bothered me that I was changing my code in order to test it, but then I started seeing that the changes made the code better overall. Now my code is littered with factory methods and similar patterns. You guys are doing good stuff.

The examples are clear and real-world. The authors address the complex issues of unit testing EJBs and web apps head-on. They don’t shy away from the real issues that come with testing these kinds of applications.
