Mastering Junit 5

Key Features

• In-depth coverage of Jupiter, the new programming and extension model provided by JUnit 5
• Integration of JUnit 5 with other frameworks such as Mockito, Spring, Selenium, Cucumber, and Docker
• Best practices for writing meaningful Jupiter test cases

Book Description

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.
