"""InterVersioned implementation tests for bzr.

These test the conformance of all the interversionedfile variations to the
22
expected API including generally applicable corner cases.

Specific tests for individual cases are in the tests/test_versionedfile.py file
24
rather than in tests/interversionedfile_implementations/*.py.
