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

### assertTimeoutPreemptively() method ###

Assertions API provide static `assertTimeoutPreemptively()` method. It is used to test long-running tasks. If given task inside the test case takes more than the specified duration, then the test will fail. 

The executable provided to the test case will be executed in the `different` thread as that of the calling code. Also, the execution of the executable will be preemptively aborted if the timeout is exceeded.
