Question

I have switched to JUnit4.4 from JUnit3.8. I run my tests using ant, all my tests run successfully but test utility classes fail with ‘No runnable methods’ error. The pattern I am using is to include all classes with name *Test* under test folder.

I understand that the runner can’t find any method annotated with @Test attribute. But they don’t contain such annotation because these classes are not tests. Surprisingly when running these tests in eclipse, it doesn’t complain about these classes.

In JUnit3.8 it wasn’t a problem at all since these utility classes didn’t extend TestCase so the runner didn’t try to execute them.

I know I can exclude these specific classes in the junit target in ant script. But I don’t want to change the build file upon every new utility class I add. I can also rename the classes (but giving good names to classes was always my weakest talent 🙂 )

Is there any elegant solution for this problem?

Assuming you’re in control of the pattern used to find test classes, I’d suggest changing it to match *Test rather than *Test*. That way TestHelper won’t get matched, but FooTest will.
