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

### assertNotEquals() method ###

Assertions API provide static `assertNotEquals()` method. This method helps us in validating that actual and expected values are `not` equal. This method uses `equals()` to assert the in-equality of actual and expected value.

- If the actual value is `not equal` to expected value then the test case will pass.
- If the actual value is `equal` to expected value then the test case will fail.


There are basically three useful overloaded methods for assertNotEquals:-
