JUnit 5 @BeforeAll annotation example

By | December 6, 2019

In this post, we will talk and learn about the JUnit 5 life cycle @BeforeAll annotation.

In JUnit 5 @BeforeAll annotation is used to signal that the annotated method should be executed before all tests in the current test Class.

It is a replacement for @BeforeClass annotation in JUnit 4.

@BeforeAll annotated method must be declared as a static method otherwise it will throw runtime error.

@BeforeAll Annotation Example

Let’s understand @BeforeAll Annotation using an example. Here I have MyUtils.java class with the add method. I will write a Junit test for this add method and we will see how we can make use of @BeforeAll Annotation in the same Unit class.

Utility Class for that we have to write JUnit Test:

JUnit Test Class with non static method(setUp()) annotated with  @BeforeAll. In this case, JUnit 5 will throw a runtime exception.

Now in the above test class, we make the setUp() method static then the test case will be executed successfully.

 The output of the above test class
