I had looked at the pylint source code, and did some python troubleshooting, I discovered the matching was only checking against the beginning of the line.  Someone in the community also offered the same suggestion (which prompted me to reply to my own post in hopes this may help someone else).   In the end, I used the following: 


I know (?P<text>) is not needed as it can't be used, but I find it useful for reading the regular expression and helping determine what a group is expected to match.

I'm trying to configure the

I came up with the following regular expression:

When I test the regular expression on https://regex101.com/r/3BXmsa/6, it matches the text I expect it to match.

However, when I run pylint against my code, it still reports a docstring is missing for a class name that ends with Tests

For example, if I have the following python 3 code.

import unittest

class _Utils(unittest.TestCase):

class Test_Foo(unittest.TestCase):

class test_Foo(unittest.TestCase):

class UtilsTests(unittest.TestCase):

    def test_function_name(self):

    def _foo(self):

    def my_tests(self):

if __name__ == "__main__":

Running pylint --disable=all --enable=missing-docstring --no-docstring-rgx='(^(test)?_)|((T|t)ests$)' ./test.py yields

$ pylint --disable=all --enable=missing-docstring --no-docstring-rgx='(^(test)?_)|((T|t)ests$)' ./test.py 

************* Module test

Your code has been rated at 7.50/10 (previous run: 7.50/10, +0.00)

I was only expecting to see the Missing module docstring violation, and the missing class docstring on line 8.

Here is my environment:

$ pylint --version

pylint 2.3.1

astroid 2.2.5

Python 3.7.3 (default, Mar 27 2019, 09:23:15) 

[Clang 10.0.1 (clang-1001.0.46.3)]

Any ideas what is going on and how to fix it?
