Gain insights into configuring and utilizing JUnit 5 for Java unit testing. Learn about writing effective unit tests, integrating assertions, assumptions, parameterized tests, and their significance.

Junit 5 is the most popular and widely used Java unit testing framework. In this course, you will learn step by step, how to configure and use JUnit 5 testing framework. This course will teach you how to write unit tests with JUnit 5, covering topics like why unit tests are important, the structure of good unit tests, assertions, assumptions and parameterized tests and more.

Java Unit Testing with JUnit 5

### @DisabledOnJre and @EnabledOnJre ###

Junit 5 helps us to disable or enable test cases using various conditions. JUnit Jupiter API provides annotations in `org.junit.jupiter.api.condition` package to enable/disable tests based on a certain condition. The annotations provided by API can be applied to test methods as well as the class itself. 
The two annotations which are applied to disable/enable tests based on the particular version of the Java Runtime Environment (JRE) are - `@DisabledOnJre` and `@EnabledOnJre`. Let's take a look at a demo.
