Unit Testing with JUnit - Tutorial
This tutorial explains unit testing with JUnit 4.x and JUnit5. It also covers the creation of JUnit tests. Running them automatically helps to identify software regressions introduced by changes in the source code. Having a high test coverage of your code allows you to continue developing features without having to perform lots of manual tests. If you want to learn more, this article is a very good choice. Unit testing is always necessary.

Microservices for Java Developers: Performance and Load Testing
These days numerous frameworks and libraries make it is pretty easy to get from literally nothing to a full-fledged running application or service in a matter of hours. However, the decisions which frameworks make on your behalf (often called “sensitive defaults”) are far from being optimal (or even sufficient) in the context of the specific application or service.
In this tutorial you will get a great overview about performance and load testing, focusing on the tools to help you with achieving your goals and also highlight the typical areas of the application to tune.
