About

Overview

The @EnumSource annotation can be attached to a parameterized test method. It's provided with a class reference to an Enumeration Type, and at runtime, each value inside this enumeration will be given to the test method. This is a great choice for testing a piece of code against all different options inside an enum.

Summary

Use @EnumSource to execute a test once for each item of an enum class
