        9. Only one method invocation is expected when testing runtime exceptions

           Code Smell
        10. Exception testing via JUnit @Test annotation should be avoided

        20. JUnit assertions should not be used in "run" methods

           Code Smell
        21. JUnit4 @Ignored and JUnit5 @Disabled annotations should be used to disable tests and should provide a rationale

           Code Smell

        • junit
        • tests
        • unused
        • confusing

        Why is this an issue?

        There’s no point in having a JUnit TestCase without any test methods. Similarly, you shouldn’t have a file in the tests directory named *Test, *Tests, or *TestCase, but no tests in the file. Doing either of these things may lead someone to think that uncovered classes have been tested.

        This rule raises an issue when files in the test directory are named *Test, *Tests, or *TestCase or implement TestCase but don’t contain any tests.
