+1 for the feature Subtests make the test results of all asserts visible at test execution time but decrease the readability of a test: @parameterized([2,4,6]) def test_method_whenCalled_returnsNone(self, a): # 1) arrange something = Something() # 2) act result = something.method(a) # 3) assert self.assertIsNone(result) When using subtests the phases of 1) arrange, 2) act, 3) assert are not clearly separated, the unit test contains logic and two additional indentation levels that could be avoided with parameterized tests: def test_method_whenCalled_returnsNone(self, a): # 1) arrange something = Something() for a in [2,4,6]: with self.subTest(a=a): # 2) act result = something.method(a) # 3) assert self.assertIsNone(result) ---------- nosy: +moormaster _______________________________________ Python tracker <rep...@bugs.python.org> <https://bugs.python.org/issue7897> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
