Practical Unit Testing with JUnit and Mockito
Source code for exercises is available online.
I have already bought TestNG book, should I also buy JUnit version?
Both books are very similar so I do not think that you need both. The difference is, that each of them uses different testing framework for all code examples. Also, because of some differences between JUnit and TestNG, some sections were changed. For example, in JUnit there is nothing about test-dependent methods.
What about source code for JUnit book?
I'm working on it. Should be available in the first half of May.
I'm not Kent Beck, so I expect you to be a little hesitant about acquiring my books. Good! You should never believe what the marketing says! :) Anyway, I’m giving you the chance here to learn from other readers whether the books are worth your money and your time.
Sample Chapter
Reviews are cool, but why not decide on your own? Here you will find one of the last chapters from the "Practical Unit Testing with TestNG and Mockito" book. The chapter explains how to make unit tests manageable, so they do not become a burden as the project develops and changes are introduced. To a large extent this chapter is independent from the underlying testing framework (JUnit or TestNG), so its content in the "Practical Unit Testing with JUnit and Mockito" book is very similar.

Practical Unit Testing with TestNG and Mockito
In two hours of reading, I knew more of the usage of TestNG and Mockito than after several days of Web crawling. Review by Francis Galiegue, from mailing list
Tomek does also a good job of not just pushing his own preferences in Java unit testing, but presenting the available choices either for test strategies or for unit testing tools.
I would recommend this book to every developer concerned by code quality, especially if you are working in a Java context. Franco Martinig, on Software Development Books site
Despite the Java/TestNG/Mockito orientation that the title might suggest, the book contains a high percentage of general unit testing knowledge that can be applied (mostly) independently of the language and tools that you are using.
This book is highly recommendable to all software developers interested in unit testing, particularly if you are working in a Java context. From Franco Martinig's blog
This book gives a lot of good, general advice on unit testing in general (and not relevant only to Java), but it also brings one very quickly in working order with its two proponent tools. In two hours of reading, I knew more of the usage of TestNG and Mockito than after several days of Web crawling. And I have learned how to do TDD (test driven development) correctly.
I liked the approach of the author to have an open view on unit testing and presenting all the available choices for testing strategies or tools selection instead of just pushing his own opinion. From review on Amazon.com site
[...] for those less familiar with testing and using TestNG and Mockito [...] this book is a totally must read as it gently introduces reader to world of proper unit testing using best tools available in Java world. Review by Tomasz Dziurko.
Bought only a few months after its publication (2012) I was delighted to find some very up-to-date content.
World would be better if every programmer read this book. The book focuses not only on the toolset which perhaps will be outdated very quickly but also/mainly on the OO design and testing principles. Review from Goodreads site

No reviews yet, but since the book is very similiar to the previous one, you could read what is written above.
Uh-oh, bugs happen, both in code and in books. Below, you will find the most prominent bugs.
BTW, if you buy the electronic version, you won't see them! :) Unfortunately, I cannot update the printed version so easily. :(
