You don't need to, as long as the filterwarnings() arguments specify the current file and the specific error message you're suppressing.

Well, that doesn't work: the current file appears to be irrelevant for deprecation warnings, and I'm not sure what "the module" argument should be. For example, in test___all__.py, this works (trial and error) to suppress the statcache warning:

warnings.filterwarnings("ignore", ".* statcache .*", DeprecationWarning, 'statcache')

But I'm not sure why I'm typing 'statcache' as the last argument. Is this meant to be a module basename, or some flavor of file path?

If we don't reset warnings after each test, and the name of the test file is usually irrelevant, then changing the order in which we run the tests may turn up new warnings (suppressed in the normal order of running the tests because each filterwarnings call affects every test run after the test that calls it).
