Run tests from inner classes via Maven.

Question

I have following tests structure:

public class WorkerServiceTest {

    public class RaiseErrorTest extends AbstractDbUnitTest{
        @Test
        public void testSomething(){
        } 

        ...
    }

    ...
}

It's done because I don't want to create a separate class file for every test case extending AbstractDbUnitTest.

The problem is that mvn test doesn't run test from my inner class. Is there is a way how to configure Maven to run such tests? Of course I can create mehtods in the parent class calling the inner class methods but I want a clearer way.

Answer 1

Yes, this is possible using the new (well, it's not new anymore) Enclosed runner (since JUnit 4.5) that runs all static inner classes of an outer class.

To use it, just annotate the outer class with @RunWith(Enclosed.class) and make the inner classes static.

@RunWith(Enclosed.class)
public class WorkerServiceTest {

    public static class RaiseErrorTest extends AbstractDbUnitTest{
        @Test
        public void testSomething(){
        } 

        ...
    }

    ...
}

And mvn test will run them.
