Other interactions: testtools extends the 'addError' etc calls to let
arbitrary additional errors or diagnostic data be attached. I don't
think we would care if non-test cases get passed in, because we
already cope with synthetic test case objects being passed in via
That said, sharing setUp and tearDown seems to make this thing very
special cased and not generally useful. Why not something like (or
even take it verbatim - I'd be happy to contribute it)
