Testing is an essential skill for any Java developer, particularly unit testing, integration testing, and automation testing. At the bare minimum, every Java developer should be familiar with JUnit and Mockito, two of the most popular Unit testing and Mock library. It provides some of the essential features like Caching and Transaction out-of-the-box, which means you have more time to focus on your application logic, than implementing caching in your application.
