Pytest 8: AttributeError: 'TestExpectedException' object has no attribute 'runTest'. Did you mean: 'subTest'? #372
Comments

Please use either the test tools test runner or the native python test runner (unittest) We're open to PRs that improve support for running the test with third party runners like pytest, but it's not a priority for the project. |

pytest 82. relies on a feature of `unittest.TestCase` where the initialization of it with the default `methodName="runTest"` is treated specially, allowing it to insantiate even without `runTest` method actually existing. See under "Changed in Python 3.2" in unittest.TestCase docs This fixes the error with pytest 8.2: AttributeError: 'TestUtil' object has no attribute 'runTest'. Did you mean: 'subTest'?
