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.

Docker

Docker (https://www.docker.com/) is an open source software technology, which allows to pack and run any application as a lightweight and portable container. It provides a command-line program, a background daemon, and a set of remote services that simplifies the life cycle of containers.

Docker in a nutshell

Historically, UNIX-style operating systems used the term jail to describe modified isolated runtime environments. The Linux Containers (LXC) project started in 2008 and brought together cgroups, kernel namespaces, or chroot (among others) to provide complete isolation execution. The problem with LXC is the difficulty, and for that reason, the Docker technology emerged.

Docker hides in underlying complexity of the...
