VScode python unittest test discover issue

Question

I can run all my tests from cmd

(venv) PS D:\13_projects\xxx> python -m unittest discover -s .\tests\ -p 'test*.py' -b
...................................
----------------------------------------------------------------------
Ran 35 tests in 0.426s

OK

but no tests are discovered by the VScode (the same test configuration settings and virtual environment is used)

    "python.testing.unittestArgs": [
        "-v",
        "-s",
        "./tests",
        "-p",
        "test*.py"
    ],

I'm sure it worked in past. As far as I realize I didn't change any settings.

This is my version of VScode

Do you have any hints what to check?

Answer 1

A couple of things to try:

1. Go through the process of configuring the tests in VSCode. Type ctrl+shift+p, then search "Python: Configure Tests".
2. See what the test output in VSCode shows when discovering the tests.
3. Ensure __init__.py files are included in your project folders, and possibly even the tests folder (even though testing doesn't usually require this). I've noticed strange behavior here before but don't recall exactly what the fix was.
