Bug description:
Testtools deliberately lets string exceptions from test cases propagate, rather than cause failures:

    except Exception:
        # Note that bare exceptions are not caught, so raised strings will
        # escape: but they are deprecated anyway.

Given that, though deprecated, such things are not completely unheard of, see <lp:~jelmer/bzr/no-string-exc> for instance, it might be worth rethinking this. Bazaar at least has various bits of core infrastruture that prefer the test suite not to randomly fall over when it has issues.
