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

This issue is open on JUnit GitHub since 2 years, and point out 2 independent issues:
- Tests depending on the execution order;
- Non repeatable tests.

Consider adressing the issue at the root, rather than trying to use the framework to do the job afterwards. Use setUp and tearDown method to guarantee isolation, and test at the smallest level.
