https://github.com/python/cpython/blob/8e836bb21ce73f0794fd769db5883c29680dfe47/Lib/unittest/case.py#L548 . _callTestMethod just calls the test method and doesn't check for the method to be a generator function to be iterated through. In Python 3.8 the call to test method was separated out as _callTestMethod. So something like below added in the original method should work. I guess there is an existing issue for this. import unittest from unittest import TestCase class BuggyTestCase(TestCase): def _callTestMethod(self, method): import inspect if inspect.isgeneratorfunction(method): list(method()) else: method() def test_generator(self): self.assertTrue(False) yield None if __name__ == "__main__": unittest.main() python3.8 test_foo.py F ====================================================================== FAIL: test_generator (__main__.BuggyTestCase) ---------------------------------------------------------------------- Traceback (most recent call last): File "test_foo.py", line 10, in _callTestMethod list(method()) File "test_foo.py", line 15, in test_generator self.assertTrue(False) AssertionError: False is not true ---------------------------------------------------------------------- Ran 1 test in 0.000s FAILED (failures=1) ---------- nosy: +ezio.melotti, michael.foord, rbcollins, xtreak _______________________________________ Python tracker <rep...@bugs.python.org> <https://bugs.python.org/issue41322> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
