How can I make my JUnit tests run in random order?

Question

I have the classical structure for tests, I have a test suite of different suites like DatabaseTests, UnitTests etc. Sometimes those suites contains other suites like SlowDa

https://github.com/KentBeck/junit/pull/386 introduces some orders but not RANDOM. Probably you do not really want this; tests should run deterministically. If you need to verify that different permutations of tests still pass, either test all permutations; or, if this would be impractically slow, introduce a “random” seed for shuffling that is determined by an environment variable or the like, so that you can reproduce any failures. http://hg.netbeans.org/main/file/66d9fb12e98f/nbjunit/src/org/netbeans/junit/MethodOrder.java gives an example of doing this for JUnit 3.
