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

# @DisplayName on @Test Methods ###

JUnit 5 `@DisplayName` annotation is also used to provide a custom name for the `@Test` methods. 
Usually, by default, JUnit 5 reporting prints the test methods name in the IDE test report and also while executing test cases. We can use `@DisplayName` annotation to provide a custom name to `Test` methods, that makes it easier to read. Thus, it acts as a metadata for our test methods.

`@DisplayName` annotation can take up string having the following things:- 

1. It can take spaces between words.
2. It can take special characters.
3. It can take emojis as well.

Let's look at a demo:-   

This lesson demonstrates how to provide custom display names to test methods.
