Hands-On Introduction to 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 to this rule is MicroShed Testing, which is part of the jakarta-ee-example project.
Current Status: 20/30 tools and libraries are covered. The next release (25/30) is scheduled for 2022.

Goals of the Book
- 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 for each testing tool & library
- Hands-on testing examples that apply for testing any Java application
Build & Test
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 verifyContent
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.
