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.
This book
- Illuminates the tradeoffs associated with testing, so you can make better decisions about what and how to test
- Introduces TestNG, explains its goals and features, and shows how to apply them in real-world environments
- Shows how to integrate TestNG with your existing code, development frameworks, and software libraries
- Demonstrates how to test crucial code features, such as encapsulation, state sharing, scopes, and thread safety
- Shows how to test application elements, including JavaEE APIs, databases, Web pages, and XML files
- Presents advanced techniques: testing partial failures, factories, dependent testing, remote invocation, cluster-based test farms, and more
- Walks through installing and using TestNG plug-ins for Eclipse, and IDEA
- Contains extensive code examples
Whether you use TestNG, JUnit, or another testing framework, the testing design patterns presented in this book will show you how to improve your tests by giving you concrete advice on how to make your code and your design more testable.

testng & rants, By Jeanne Boyarsky (New York, NY) - See all my reviews
This review is from: Next Generation Java Testing: TestNG and Advanced Concepts (Paperback)
"Next Generation Java Testing" has a subtitle: "TestNG and Advanced Concepts." This isn't surprising given the creator of TestNG is an author, but is important to realize. It starts with 6.5 pages on why TestNG is better than JUnit 3.8. Then only two paragraphs on JUnit 4. This has been a pet peeve of mine for some time. It's like comparing the current version of C# to Java 1.3 and then saying Java is worse because it doesn't have generics.I liked the code snippets in the TestNG sections as they focused on relevant pieces. The examples were to the point. Especially the performance and J2EE sections. I liked the concepts described in chapter 2 (over 100 pages.) The authors describe open source libraries that integrate with TestNG. I liked this coverage although JMock could have used a code example for comparison (easyMock had one.) Ant targets were provided for the code coverage examples. Chapter seven is titled "digressions." Some quotes... Read more

5 with a Few Qualms, By
Amazon Verified Purchase(What's this?)
This review is from: Next Generation Java Testing: TestNG and Advanced Concepts (Paperback)
This was not the book I expected, but it makes a lot of sense that it turned out this way. Cedric is like the Martin Luther of the testing world. I ranted about a lot of the same things in JUnit, especially for instance, the whole crazy TestDecorator business, but Cedric just blew the house down. TestNG, after JUnit, was like getting out of jail.So it makes sense that this book is a kind of exhaustive compendium of testing approaches, and as such, it succeeds, in most ways. There are a few things that don't show up, for instance, there is discussion of container testing, but Shale is not mentioned (unit testing JSF is made much better by it, and JSF is part of JEE5 so it deserves attention). The section on testing XML was good, considering dom4j, XMLUnit, etc., but it ends too quickly. For instance, what about using XPath statements? or some schema tools? Given that Cedric's partner in crime, of Bileblog fame, was aboard for this outing, rants were bound to... Read more

Practical Testing with a very good framework, By
This review is from: Next Generation Java Testing: TestNG and Advanced Concepts (Paperback)
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... Read more |
