Java – Running junit tests in parallel in a Maven build


I'm using JUnit 4.4 and Maven and I have a large number of long-running integration tests.

When it comes to parallelizing test suites there are a few solutions that allow me to run each test method in a single test-class in parallel. But all of these require that I change the tests in one way or another.

I really think it would be a much cleaner solution to run X different test classes in X threads in parallel. I have hundreds of tests so I don't really care about threading individual test-classes.

Is there any way to do this?
