How to ignore class in junit?

Sometimes it so happens that our code is not completely ready while running a test case. As a result, the test case fails. The @Ignore annotation helps in this scenario.

Now let's see @Ignore in action.

Create a java class to be tested, say, MessageUtil.java in C:\>JUNIT_WORKSPACE.

Create a java class file named TestJunit.java in C:\ JUNIT_WORKSPACE.

Create a java class file named TestRunner.java in C:\>JUNIT_WORKSPACE to execute test case(s).

Compile the MessageUtil, Test case and Test Runner classes using javac.

Now run the Test Runner, which will not run the testPrintMessage() test case defined in the provided Test Case class.

Verify the output. testPrintMessage() test case is not tested.

Now, update TestJunit in C:\>JUNIT_WORKSPACE to ignore all test cases. Add @Ignore at class level.

Compile the test case using javac.

Keep your Test Runner unchanged as follows −

Now run the Test Runner, which will not run any test case defined in the provided Test Case class.

Verify the output. No test case is tested.

• A test method annotated with @Ignore will not be executed.
• If a test class is annotated with @Ignore, then none of its test methods will be executed.

In this case, you need to use @Ignore with the @Test annotation for a test method you wish to skip. The annotation could also be applied to the test class, to skip all the test cases under a class. In this case, you need to use @Ignore at the class level.
