Why can't coverage the data in the "if __name__ == "__main__":"

test.py

if __name__ == "__main__":
    print("hello world!")

run：pytest --cov=./ test.py

output：

----------- coverage: platform linux, python 3.9.9-final-0 -----------
Name      Stmts   Miss  Cover
-----------------------------
test.py       2      1    50%
-----------------------------
TOTAL         2      1    50%

The normal coverage rate should be 100%. why 50%.

@Segelzwerg you’re using multiprocessing in your test suite, support for it was removed in pytest-cov 4. See the changelog for migration path: https://pytest-cov.readthedocs.io/en/latest/changelog.html

@ionelmc thanks for the advice. I didn’t realize it. Will investigate now!
