Full Overview of the Java Testing Ecosystem

This repository contains the source code for the book 30 Testing Tools & Libraries Every Java Developer Must Know.

You can find the source code for the various testing tools & libraries within spring-boot-example/src/test/java/de/rieckpil/blog. Each tool & library has its dedicated Java package. The only exception is MicroShed Testing, which is part of the jakarta-ee-example project.

Current Status: 15/30 tools and libraries are covered. The next release (20/30) is scheduled for Q4 2021.

• Enrich your existing testing toolbox
• Use the right tool for the job
• Inform about various tools & libraries of the Java testing ecosystem
• Cookbook-style introduction of each tool & library
• Hands-on testing examples that apply for testing any Java application

Requirements:

• Java 11: java -version
• A running Docker engine (required for Testcontainers): docker info

Build the project and run all tests with:

cd spring-boot-example
./mvnw verify

cd jakarta-ee-example
./mvnw verify

The book uses a Spring Boot and Jakarta EE application to demonstrate the different tools & libraries. Both sample applications only use a minimal subset of Spring Boot/Jakarta EE features so that you can easily apply the knowledge to your tech stack.
