Rendering the traceback of an HTTPError causes in INTERNALERROR #10797
Description
pytest >= 7.2 uses the exceptiongroup library while rendering tracebacks.
If the exception is a urllib.error.HTTPError python/cpython#90113 occurs causing an INTERNALERROR.
(pytest < 7.2 does not have this problem.)
Minimal example:
from urllib.error import HTTPError
def test_HTTPError():
raise HTTPError(
'http://localhost', '500', 'Internal Server Error', hdrs=(), fp=None)Traceback
