Pragmatic Unit Testing in Java 8 With JUnit, you learn to write and run manageable unit tests in JUnit with confidence. You will learn mnemonics to help you know which tests to write, how to remember all the boundary conditions, and what the qualities of a good test are. You’ll see how effective unit testing can be profitable by allowing you to keep your make your java code clean, and you’ll learn how to deal with things that seem too difficult to test.

Pragmatic Unit Testing in Java 8 With JUnit, you walk through all the important unit testing topics. If you’ve never written a unit test before, you’ll see screenshots from Eclipse, IntelliJ IDEA, and NetBeans to make it easy to understand. After you’ve gotten through the basics, you’ll learn why you want to write unit tests and how to use JUnit effectively. But the good thing of the book explains unit testing wisdom compiled by the folks out there who have been doing it on production systems for at least 15 years: veteran author and developer Jeff Langr, drawing on the wisdom of the pragmatic programmers Andy Hunt and Dave Thomas. You learn:

How to design your unit tests to minimize your maintenance efforts.
How to use unit tests to keep your system clean.
How to prove difficult things.
Memorable mnemonics to help you remember what is important when writing unit tests.
How to help your team realize and maintain the benefits of unit testing.

JUnit in Action Third Edition

By Catalin Tudose contains dozens of practical examples illustrate JUnit 5 innovation for dependency injections, nested tests, parametricized tests, etc. In less time, you will learn to use JUnit 5 to automate your tests, a process that takes less resources and gives you more time to develop. When Junit was first introduced by Kent Beck and Eric Gamma, the Eagle movement began in infancy, “test drive development” was unknown, and unit testing usually began to enter the developer’s vocabulary. Today, most developers recognize the benefits of unit testing and rely on the increasingly sophisticated equipment now available. JUnit represents the state of the art testing frameworks and provides important new features to improve the Java programming development process.

A timeless guide to single testing of Java applications (including the Union Java EE application) using Javit in Action, the Javanese framework and its extensions. This book provides real-world problem-solving techniques such as testing AJX applications, using mockups to perform test isolation, container testing and test automation for Java EE and database applications. Written to help readers use JUnit, the book includes recent innovations such as new annotations that simplify writing tests, improve exception management, and incorporate new hardware methods. You’ll also learn how to use JUnit extensions to test new styles and application frameworks, including Ajax, OSGi, and HTML presentation layers.

Using a sample-based approach, various unit testing techniques such as EJBs, database applications and web applications are covered. Test techniques using the free open source framework and tools available and how to test units in isolation with phantom objects are also discussed. The book will also inform you about the latest developments in TDD, BDD, continuous integration and other practices related to unit testing. Previous editions were authored by Petar Tahchiev, Felipe Leme, Gary Gregory, and Vincent Massol.
