Bug report

In Python 3.12, a new exit code (5, instead of0) wasadded if all tests were skipped inunittest. But in some cases it still returns0. See code examples.

Code example 1:

importunittestclassTestSimple(unittest.TestCase):@classmethoddefsetUpClass(cls):raiseunittest.SkipTest("Skip whole Case")deftest_true(self):self.assertTrue(True)deftest_false(self):self.assertTrue(False,msg="Is not True")

Output:

Ran 0 tests in 0.000sNO TESTS RAN (skipped=1)

Ok, we get exit code 5 here.

Code example 2:

importunittestclassTestCase(unittest.TestCase):@unittest.skip("something")deftest(self):self.assertTrue(False)

Output:

Ran 1 test in 0.000sOK (skipped=1)

Here we can see output0. Ran one test and skipped. But I think it is incorrect, because all tests were skipped.

Your environment

• CPython versions tested on: 3.12
• Operating system and architecture: I think it does not matter.
