Bug report

In Python 3.12, a new exit code (5, instead of 0) was added if all tests were skipped in unittest. But in some cases it still returns 0. See code examples.

Code example 1:

import unittest class TestSimple(unittest.TestCase): @classmethod def setUpClass(cls): raise unittest.SkipTest("Skip whole Case") def test_true(self): self.assertTrue(True) def test_false(self): self.assertTrue(False, msg="Is not True")

Output:

Ran 0 tests in 0.000s NO TESTS RAN (skipped=1) 

Ok, we get exit code 5 here.

Code example 2:

import unittest class TestCase(unittest.TestCase): @unittest.skip("something") def test(self): self.assertTrue(False)

Output:

Ran 1 test in 0.000s OK (skipped=1) 

Here we can see output 0. 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.
