New submission from Xinmeng Xia <[email protected]>:
In Python 3.11, unittest.assertRaisesRegex is broken and leading to crashing if
tested regex does not match name. See the following example:
test.py
=========================================
import unittest
class uTest(unittest.TestCase):
pass
uTest = uTest()
with uTest.assertRaisesRegex(Exception, 'aaa'):
aab
=========================================
Output in Python3.9.2, 3.10:
--------------------------------------
NameError: name 'aab' is not defined
During handling of the above exception, another exception occurred:
Traceback (most recent call last):
File "/home/xxm/Desktop/test.py", line 29, in <module>
aab
File "/usr/local/python310/lib/python3.10/unittest/case.py", line 239, in
__exit__
self._raiseFailure('"{}" does not match "{}"'.format(
File "/usr/local/python310/lib/python3.10/unittest/case.py", line 163, in
_raiseFailure
raise self.test_case.failureException(msg)
AssertionError: "aaa" does not match "name 'aab' is not defined
--------------------------------------------------
Actual output in Python3.11.0a1,Python3.11.0a2:
