Overview of this book

A practical and easy-to-follow, yet comprehensive, guide to learning advanced JUnit testing. Each topic is explained and placed in context, and for the more inquisitive, there are more details of the concepts used. This book is for you if you are a developer with some experience in Java application development as well as a basic knowledge of JUnit testing. But for those whose skill set is void of any prior experience with JUnit testing, the book also covers basic fundamentals to get you acquainted with the concepts before putting them into practise.

Exploring the FindBugs plugin

This section describes the configuration and usage of the FindBugs plugin.

FindBugs works with three types of errors. You can visit http://findbugs.sourceforge.net/bugDescriptions.html for the FindBugs error details. The following are the FindBugs-supported error categories and errors:

  • Correctness bug: This is an apparent coding mistake that results in code that was probably not what the developer intended; for example, a method ignores the return value of a self-assigned field. The following are a few examples of a correctness bug:
    • The class defines tostring() but it should be toString()
    • A value is checked here to see whether it is null, but this value can't be null because it was previously dereferenced, and if it were null, a null pointer exception would have occurred at the earlier dereference
    • The method in the subclass doesn't override a similar method in a superclass because the type of a parameter doesn't exactly match the type of the corresponding...
