JUnit Annotations
Overview
Let’s learn about JUnit Annotations in this tutorial. JUnit is a popular Java testing framework that is used for unit testing. JUnit provides a set of annotations that allow you to control the behavior of test methods and manage the test lifecycle.
JUnit Annotations
JUnit Annotations are special markers that you apply to methods or classes to indicate their purpose or behavior. Annotations give additional instructions regarding the commands that use them.
Some Junit Annotations are as follows:
@Test
The @Test annotation specifies that the method that’s annotated is a test method. This annotation is used to mark a method as a test method. JUnit will execute methods annotated with @Test when running tests.
@Before
The @Before annotation is used to mark a method that should be executed before each test method. It’s often used to set up common test data or resources.
@After
The @After annotation is used to mark a method that should be executed after each test method. It’s often used to release resources or perform cleanup tasks.
@BeforeClass
@BeforeClass annotation is used to mark a method that should be executed once before any test methods in the test class are run. It is used for expensive setup operations.
@AfterClass
@AfterClass annotation is used to mark a method that should be executed once after all test methods in the test class are run.
@Ignore
@Ignore annotation specifies that the specific method should be ignored
