Issue with pytest 8.2.0 and tornado async tests

[arossert]

I'm using the AsyncHTTPTestCase and AsyncHTTPSTestCase from tornado and the latest pytest fails in collection on this error:

Error
collection failure
Stacktrace
usr/local/lib/python3.8/site-packages/tornado/testing.py:180: in __init__
    setattr(self, methodName, _TestMethodWrapper(getattr(self, methodName)))
E   AttributeError: 'AsyncHTTPTestCase' object has no attribute 'runTest'

The issue does not exists in 8.1.0

Thanks the report, I will look into it.

• Regressed in 1a5e0eb

• That commit relies on a feature of unittest.TestCase where initializing it with the default methodName="runTest" is treated specially, allowing to instantiate even without runTest method actually existing. This is documented under "Changed in Python 3.2" in unittest.TestCase docs.

• Tornado doesn't follow this, assumes that the methodName exists even with the default.

My preference would be to fix Tornado, I will try to submit a patch. Otherwise will fix in pytest somehow.
