Subject: [PATCH] Treat methodName="runTest" similar to unittest.TestCase

pytest 8.2 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'?
