About this course

JUnit is a unit testing framework for Java that tests the functionality of an application to ensure it runs as expected. The “units” being tested are single entities, like classes and methods. Proper testing practices can not only keep code organized and maintain a solid direction, but it also ensures maintainability in the future and is friendly to a team-based setting.
