VS Code not finding pytest tests

I have PyTest setup in vs-code but none of the tests are being found even though running pytest from the command line works fine.

(I'm developing a Django app on Win10 using MiniConda and a Python 3.6.6 virtual env. VS Code is fully updated and I have the Python and Debugger for Chrome extensions installed)

Pytest.ini:

[pytest]
DJANGO_SETTINGS_MODULE = callsign.settings
python_files = tests.py test_*.py *_tests.py

vs-code workspace settings:

{
    "folders": [
        {
            "path": "."
        }
    ],
    "settings": {
        "python.pythonPath": "C:\\ProgramData\\Miniconda3\\envs\\callsign\\python.exe",
        "python.unitTest.unittestEnabled": false,
        "python.unitTest.nosetestsEnabled": false,
        "python.unitTest.pyTestEnabled": true,
        "python.unitTest.pyTestArgs": ["--rootdir=.\\callsign", "--verbose"]
    }
}

Finally, the output from the Python Test Log inside VS code:

======================== no tests ran in 1.12 seconds =========================

Am I missing any steps to get vs-code to find the tests?

If anyone comes across this post-2020, this issue in the vscode-python repo saved my life. Basically, just do the following:

1. Uninstall the Python extension
2. Delete the file that contains the extension from your ~/.vscode folder (mine looked like ms-python.python-[YEAR].[MONTH].[VERSION])
3. Reinstall the extension

Worked like a charm.
