For TestCaseWithMemoryTransport the ``test_home_dir`` is set to the name of
2429
a directory which does not exist. This serves to help ensure test isolation
2430
is preserved. ``test_dir`` is set to the TEST_ROOT, as is cwd, because they
2431
must exist. However, TestCaseWithMemoryTransport does not offer local file
2432
defaults for the transport in tests, nor does it obey the command line
2433
override, so tests that accidentally write to the common directory should
2436
:cvar TEST_ROOT: Directory containing all temporary directories, plus a
