Setting the name of a test in JUnit

Changing the name of a test can be done by either changing the method name or by using the @DisplayName annotation. In the following example, you see the @DisplayName annotation on the class and the test method.

        // Test code here
    }
}

The names of the test will now look different in the console. When you run the previous tests in IntelliJ the result will look like the following:
