xfail isn't just for pytest tests. Python's unittest has @unittest.expectedFailure.

In this episode, we cover:

• using @unittest.expectedFailure
• the results of passing and failing tests with expectedFailure
• using pytest as a test runner for unittest
• using pytest markers on unittest tests

Docs for expectedFailure:
 https://docs.python.org/3/library/unittest.html#skipping-tests-and-expected-failures

Some sample code. 
 unittest only:

import unittest class ExpectedFailureTestCase(unittest.TestCase): @unittest.expectedFailure def test_fail(self): self.assertEqual(1, 0, "broken") @unittest.expectedFailure def test_pass(self): self.assertEqual(1, 1, "not broken")

unittest with pytest markers:

import unittest import pytest class ExpectedFailureTestCase(unittest.TestCase): @pytest.mark.xfail def test_fail(self): self.assertEqual(1, 0, "broken") @pytest.mark.xfail def test_pass(self): self.assertEqual(1, 1, "not broken")
