AttributeError when running unittest with coverage in Python 2.7 on WSL

Question

I'm encountering an error while attempting to run unit tests with unittest and coverage in Python 2.7 on a Windows 11 system using WSL (Windows Subsystem for Linux). The error message suggests an issue with finding the test case test_admin_ruta_total_posiciones within the tests module.

Error Message:

Traceback (most recent call last):
  File "/usr/lib/python2.7/unittest/__main__.py", line 12, in <module>
    main(module=None)
  File "/usr/lib/python2.7/unittest/main.py", line 94, in __init__

    parent, obj = obj, getattr(obj, part)
AttributeError: 'module' object has no attribute 'test_admin_ruta_total_posiciones'

Context:

I'm running Python 2.7 within a WSL environment on Windows 11. My project structure includes a tests directory where test_admin_ruta_total_posiciones.py resides. This file contains several unit tests using unittest.

Code Snippet:

import unittest

class TestAdminRutaTotalPosiciones(unittest.TestCase):
    # Test methods...

What could be causing this AttributeError during test discovery with unittest in a Python 2.7 environment on WSL, and how can I resolve it to successfully run my tests with coverage?

Steps Taken:

1. Verified that test_admin_ruta_total_posiciones.py contains valid test methods within a unittest.TestCase subclass.
2. Confirmed the directory structure is correct and tests is recognized as a module within the WSL environment.
3. Attempted to execute tests with coverage using the command coverage run -m unittest tests.test_admin_ruta_total_posiciones, resulting in the above error.

Expected Outcome:

I expect unittest to discover and execute the tests defined in test_admin_ruta_total_posiciones.py, while coverage should generate a coverage report without encountering errors.

Additional Notes:

• The setUp method within TestAdminRutaTotalPosiciones initializes necessary dependencies (db_beta, etc.) and sets configuration flags (EJECUTAR).
• Other test methods (test_soporte_sin_db, test_admin_db, etc.) within the same test class encounter similar issues during test discovery.
