Is there a JUnit TestRunner for running groups of tests?

Question

I am currently using JUnit 4 and have a need to divide my tests into groups that can be run selectively in any combination. I know TestNG has a feature to annotate tests to assi

First, you are addressing two problems - unit tests (often in the same package as the unit under test) and integration tests. I usually keep my integration tests in a separate package, something like com.example.project.tests. In eclipse, my projects look like:

project/
  src/
    com.example.project/
  tsrc/
    com.example.project/
    com.example.project.tests/

Right-clicking on a package and selecting 'run' runs the tests in the package; doing the same on the source folder runs all the tests.

You can acheive a similar effect, although you expressed a disinterest in it, by using the Suite runner. However, this violates DRY - you have to keep copies of the test names up to date in the suite classes. However, you can easily put the same test in multiple suites.

@RunWith(Suite.class)
@Suite.SuiteClasses( { 
    TestAlpha.class, 
    TestBeta.class })
public class GreekLetterUnitTests {
}

Of course, I really should be keeping these things automated. A good method for doing that is to use the Ant task.
