Twisted: Incompability with pytest.skip and Twisted 25.5

[nicoddemus]

The recently released twisted 25.5.0 is causing the test test_trial_exceptions_with_skips to fail:

https://github.com/pytest-dev/pytest/actions/runs/15509383216/job/43668300225?pr=13496

Created this MWE:

from __future__ import annotations

from twisted.trial import unittest

import pytest


class TC(unittest.TestCase):
    def test_hello(self):
        pytest.skip("skip_in_method")

λ uvx --with pytest,twisted==24.11 pytest testing\test_trial.py -q
s                                                                                                                                                                                                         [100%]

See analysis here https://github.com/twisted/twisted/issues/12467#issuecomment-2955458914. pytest patches twisted.python.failure.Failure.__init__ and it breaks in Twisted 25.5 because there's an additional except/raise pair in Twisted test framework code.

Thanks @p12tic appreciate the link.

We are happy to fix pytest, after all we are patching the internals. Do you have any suggestion on how we can fix pytest?
