Mastering Void Method Testing with Mockito & JUnit 5 in Spring Boot Applications

Testing is an essential part of any software development process. Mockito, a powerful mocking framework, can help you test different parts of your application, including void methods. Void methods can be challenging to test, as the focus is on the program flow rather than the output. In this blog post, we will explore how to effectively test void methods using Mockito in a Spring Boot application.

For Maven:

For Gradle:

These dependencies will bring in Mockito and other necessary testing libraries. For a complete project setup, feel free to use the prepared Spring initializr.
