Description

JUnit has matured to become the most important tool when it comes to automated developer tests in Java. Supported by all IDEs and build systems, it empowers programmers to deliver software features reliably and efficiently. However, writing good unit tests is a skill that needs to be learned; otherwise it's all too easy to end up in gridlocked development due to messed up production and testing code. Acquiring the best practices for unit testing will help you to prevent such problems and lead your projects to success with respect to quality and costs. This book explains JUnit concepts and best practices applied to the test first approach, a foundation for high quality Java components delivered in time and budget. From the beginning you'll be guided continuously through a practically relevant example and pick up background knowledge and development techniques step by step. Starting with the basics of tests organization you'll soon comprehend the necessity of well structured tests and delve into the relationship of requirement decomposition and the many-faceted world of test double usage. In conjunction with third-party tools you'll be trained in writing your tests efficiently, adapt your test case environment to particular demands and increase the expressiveness of your verification statements. Finally, you'll experience continuous integration as the perfect complement to support short feedback cycles and quality related reports for your whole team. The tutorial gives a profound entry point in the essentials of unit testing with JUnit and prepares you for test-related daily work challenges.

What you will learn

Organize your test infrastructure and resources reasonably Understand and write well structured tests Decompose your requirements into small and independently testable units Increase your testing efficiency with on-the-fly generated stand-in components and deal with the particularities of exceptional flow Employ runners to adjust to specific test demands Use rules to increase testing safety and reduce boilerplate Use third party supplements to improve the expressiveness of your verification statements

I always appreciate a book that starts off with a 'Getting Started' section that actually get's you started but left out a huge history lesson. The first page clearly explains why unit testing is so important, and how regression occurs in projects. The first graphical depiction of a unit test was displayed around page 4, and was I the only person who spotted the depth of inheritance value of 2? That's superb! As for my favorite chapter it would be 2, and it's simply because it was the 'who, what, when, where, and why' chapter. It really set my expectations of the proceeding chapters, if I can understand what's suppose to occur than I can program for it to occur properly. The quotes throughout the book are neat as well, they break up the huge chunks of information that needs to be digested and are just subtle enough to not annoy you.By the end of the book you'll understand why unit testing is important, how to get started, and how to get some automated tests going while you sleep over night. The ebook edition has some nice color coded graphics that really speak to the text, I find this to be extremely helpful as well as mandatory. Final note: UML Diagrams.. absolutely satisfied these were used in the book! Highly recommend picking up a copy of this title and getting started with unit testing.

This book is a good way to familiarize yourself with JUnit and some testing practices.

Xanan Feb 04, 2017

The book is a good introduction to Test Driven Development and Unit Testing.JUnit is discussed along the way to illustrate how it addresses various aspects of unit testing.The author does a good job at explaining the various concepts and presenting pros and cons of the various alternatives JUnit provides to achieve testing.More advanced topics like Runners and Rules are also covered.Mockito is introduced when test doubles are discussed and brief coverage is given to Hamcrest and AssertJ.API coverage is not exhaustive.Given the book size and its title, I did not expect to find a full chapter devoted to well structuring and properly naming unit tests and another one on continuous integration.Some parts of the book seem to be biased toward teaching how to do effective unit testing rather than actually using JUnit.The book subtitle "Master high-quality software development driven by unit tests" hints at something more than JUnit.
