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

# Assumptions in JUnit 5 ###

Assumptions in JUnit 5 is a collection of utility methods that support conditional test execution based on assumptions.
In comparison to failed assertions, failed assumptions do not result in a test failure; rather, a failed assumption results in a test being aborted.

Assumptions are typically used whenever it does not make sense to continue execution of a given test method — for example, if the test depends on something that does not exist in the current runtime environment.

If the assumptions are not satisfied then, `TestAbortedException` is thrown.

There are 3 types of Assumptions in Junit 5: 

- `assumeTrue`
- `assumeFalse`
- `assumingThat` 

In the upcoming lesson, let's look into each `Assumptions` in detail.

This lesson describes Assumptions in JUnit 5 and its usage.
