PyCharm test right-click run: builtins.tuple AttributeError object has no attribute

Question

After an update and some project import, something very weird happens to my tests once run from Pycharm. I already fixed the general unittest runner config, but I am not being able to do it when running single tests, both in the config and just with a right click, which is quite comfortable.

Here is a very simple example code:

import unittest

class TestTheTester(unittest.TestCase):

    @classmethod
    def setUpClass(cls) -> None:
        cls.name = "TestTheTester"

    def test_unittest(self):
        self.assertEqual("TestTheTester", self.name)

Running it from the Shell:

python3 -m unittest tests/test_the_tester.py 
.
----------------------------------------------------------------------
Ran 1 test in 0.000s

OK

Running it from PyCharm by right-click on it (option "Run 'Python test in tests...'):

/usr/bin/python3.8 /snap/pycharm-community/252/plugins/python-ce/helpers/pycharm/_jb_trialtest_runner.py --path /home/user123/development/Project456/tests/test_the_tester.py
Testing started at 10:26 ...
Launching trial with arguments --reporter=teamcity /home/user123/development/Project456/tests/test_the_tester.py in /home/user123/development/Project456/tests/


Error
Traceback (most recent call last):
Failure: builtins.tuple: (<class 'AttributeError'>, AttributeError("'TestTheTester' object has no attribute 'name'"), <traceback object at 0x7fc59e432f00>)

The Run/Debug Configuration it creates is:

• 'Python tests' one
• Autodetect's Target 'Script path' to /home/user123/development/Project456/tests/test_the_tester.py
• Python interpreter Project Default (/usr/bin/python3.8)
• Working directory /home/user123/development/Project456/tests/
• Both options 'Add content roots to PYTHONPATH' and 'Add source roots to PUTHONPATH' selected

I'm not sure you found out the solution though, I fixed the same problem after changing test files' name to start with 'test_' and initiating a class for the test in "setUp" method.

In my case, my test code which worked perfectly didn't work at all after install some libraries with the error message below:

Error
Traceback (most recent call last):
Failure: builtins.tuple:

I hope you solved the issue already!
