Ran 232 tests in 0.408s
FAILED (errors=6)When running ./python -m test test_dataclasses, the tests all pass successfully. My understanding is that python -m test is the recommended way of running tests, but it's confusing to have it support running the file directly, but have the tests fail.
I'm not sure what the cause of the failure is.
