* bzrlib/tests/blackbox/test_push.py: (TestPushStrictMixin.assertPushFails): Ensure that the error message mentions --no-strict. (TestPushStrictMixin.assertPushSucceeds): Rely on branches only to satisfy dpush needs. Check the warning in the error message.
* bzrlib/tests/blackbox/test_dpush.py: (TestDpushStrictMixin): Simplified now that the base class do less assumptions.
