highly recommended

so when am I going to learn testng?

This book is not really about testng. it's more about the author's opinions about testing, which are for the most part valid, but I bought this book mostly for the testng part, and I guess I'll have to wait to find something more targeted towards teaching just testng.

A top recommendation.

College-level libraries strong in Java programming guides need NEXT GENERATION JAVA TESTING: unlike many Java programmer's guides, it provides a pragmatic discussion for Java developers interested in building stronger code for applications, and packs in chapters discussing testing methods, tradeoffs associated with testing, applications of testing theory and rules, analysis of partial failures and remote invocation, and more. In-depth and extensive code examples throughout also differentiate NEXT GENERATION JAVA TESTING from competitors, making it a top recommendation.

Practical Testing with a very good framework

At last a book that deals with testing applications (in java) that seems to be written by author's who have worked with real life, non trivial projects(TDD with adding two money objects together, anyone?).
This book describes using TestNG along with some advanced TestNG concepts and goes on to show how to use the framework to test out JEE projects. There are also chapters showing the developer how to integrate TestNG with other frameworks (like spring, DBUnit, jwebunit etc) which is useful as this is perhaps the only place where JUnit is better than TestNG. Inspite of the fact that TestNG documentation is pretty good, this book is worthwile buying (even if you use JUnit as your testing tool of choice).
There is useful coding and refactoring advice along the way(also a commentary on TDD), and a miscellaneous chapter of sorts which seems to have been written by Hani and edited by Cedric to remove all profanities!.
I do hope the author's expand the testing enterprise application bits to cover more testing scenarios and examples in later additions.

Pragmatic Java Testing: TestNG and Author's Rants

This book does a great job of introducing TestNG, showing how to use its features to set up tests for code that (inevitably) depends on various JEE APIs, and how to perform different kinds of testing (browser, database, performance etc).

There are some claims that I found hard to follow: For example, the authors advise against using mock objects to stub out external classes, then later state that servlets are hard to test outside of a container because they depend on a few external classes -- never mind that these are simple to mock out, and that the Spring testing library (which they mention elsewhere) even provides mock implementations for these classes. There are also some minor factual errors that should have been caught in the reviewing process (e.g. contrary to what is claimed, annotations can be inherited).

Then there is the "Digressions" chapter, which, as others have pointed out, should have been posted as a series of blog posts. Instead, there are some areas where more detail could have been provided. e.g. on how groups work in TestNG, or the exact semantics of the parallel test execution options. Now that TestNG has been out for a while and gained a lot of popularity, I'm sure there is also a lot more information on common problems that could be included in a future 2nd edition!

Very informative and nicely written

Very nicely written keeping real world requirements in mind. Could have had some more examples.

Enterprise Java developers must achieve broader, deeper test coverage, going beyond unit testing to implement functional and integration testing with systematic acceptance. Next Generation Java? Testing introduces breakthrough Java testing techniques and TestNG, a powerful open source Java testing platform.

Cédric Beust, TestNG's creator, and leading Java developer Hani Suleiman, present powerful, flexible testing patterns that will work with virtually any testing tool, framework, or language. They show how to leverage key Java platform improvements designed to facilitate effective testing, such as dependency injection and mock objects. They also thoroughly introduce TestNG, demonstrating how it overcomes the limitations of older frameworks and enables new techniques, making it far easier to test today's complex software systems.

Pragmatic and results-focused, Next Generation Java? Testing will help Java developers build more robust code for today's mission-critical environments.
