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

## assumingThat() ###

Assumptions API in JUnit 5 has a static utility method called, `assumingThat()`. This method takes a boolean assumption and an Executable. It validates the given assumption and based on its outcome it decides whether to execute an Executable or not.
- If the assumption is invalid, this method does nothing.
- If the supplied assumption is valid, it executes the supplied Executable.

There are basically two useful overloaded methods for assumingThat.
