Mastering Software Testing with JUnit 5

By: Boni Garcia

Overview of this book

When building an application it is of utmost importance to have clean code, a productive environment and efficient systems in place. Having automated unit testing in place helps developers to achieve these goals. The JUnit testing framework is a popular choice among Java developers and has recently released a major version update with JUnit 5. This book shows you how to make use of the power of JUnit 5 to write better software. The book begins with an introduction to software quality and software testing. After that, you will see an in-depth analysis of all the features of Jupiter, the new programming and extension model provided by JUnit 5. You will learn how to integrate JUnit 5 with other frameworks such as Mockito, Spring, Selenium, Cucumber, and Docker. After the technical features of JUnit 5, the final part of this book will train you for the daily work of a software tester. You will learn best practices for writing meaningful tests. Finally, you will learn how software testing fits into the overall software development process, and sits alongside continuous integration, defect tracking, and test reporting.

Beyond JUnit 5.0

JUnit 5.0 GA (General Availability) was released on September 10, 2017. Furthermore, JUnit is a living project, and new features are planned for the next release, that is, 5.1 (with no release agenda scheduled at the time of writing). The backlog for the next release of JUnit 5 can be seen on GitHub: Among other, the following features are planned for JUnit 5.1:

  • Scenario tests: This feature has to do with the capability of ordering different test methods within a class. To do that, the following annotations are planned:
    • @ScenarioTest: A class-level annotation used to denote that a test class contains steps that make up a single scenario test.
    • @Step: A method-level annotation used to denote that a test method is a single step within the scenario test.
    • Support for parallel tests execution: Concurrency is one of...
