How can I specify JUnit test dependencies?

Question

Our toolkit has over 15000 JUnit tests, and many tests are known to fail if some other test fails. For example, if the method X.foo() uses functionality from Y.bar() and YTe

There really isn't something like this that I'm aware of. (Edit: you learn something new every day :)) In my opinion, this isn't that bad of a thing (though I can see it being useful, especially when JUnit it being used for other forms of automated tests - e.g., integration tests). Your tests, IMO, aren't in the strictest sense of the word "unit tests" (at least not the test for X#foo()). Tests for X#foo() should succeed or fail depending only on the implementation of X#foo(). It should not be dependent on Y#foo().

What I'd do in your position is to mock out Y, and implement something like MockY#foo() with very simple, controlled behavior, and use it in X#foo()'s tests.

That said, with 15,000 tests, I can see how this would be a pain to refactor. :)
