I'd like to propose adding in beforeAll/afterAll hooks to test modules. Similar to the functions of the same name in Jasmine or before/after in Mocha. It would be convenient to have a way to access the testing context at the start and end of a module on a case-by-case basis instead of just the sweeping moduleDone and moduleStart callbacks.

I apologize if this has been discussed before, couldn't seem to find any background on the matter.
