Python test failing ERROR: file not found: ./test_mything_plugin.py::test_get_conn

very similar to issue #8222 on the vscode-python github.com issues list, but that thread seemed dead, so I am opening a new one

VSCode Remote - SSH

I am using VSCode Remote - SSH to do all dev and testing on a remote linux system, version 0.48.0

VSCode Extensions

Using only the VSCode Python extension ms-python.python version 2019.11.50794
I used to use the python test extension but that capability is now absorbed into the python extension, which is great

VSCode project settings.json

{
    "python.pythonPath": "/local/me/opt/miniconda3/envs/deathstar/bin/python",
    "python.testing.pytestArgs": [
        "test",
        "--disable-warnings",
    ],
    "python.testing.unittestEnabled": false,
    "python.testing.nosetestsEnabled": false,
    "python.testing.pytestEnabled": true,
}

Python

$ python --version
Python 3.6.8 :: Anaconda, Inc.

$ python -c "import pytest;print(pytest.__version__)"
5.3.1

Expected behavior

VSCode is able to execute the tests as shown in the test discovery.
VSCode adornments show in test .py files

Actual behavior

Test discover works and the tests show in the Test Explorer, great!
Test adornments do not show in the Text Editor window
When running a test, the test file, which was already discovered, cannot be found and the test execution fails out with stack trace in DEBUG CONSOLE

_when I hit the debug button, I get nothing, but when I hit the Play button, I get this

Thanks for the bug report! We just wanted to quickly acknowledge we received it and we will triage this as soon as we can.

Todd Jones (@toddljones) Can you share the layout of your workspace folder? I want to understand where the test file is with respect to the current working directory.

I just created a mock project to simplify things and so as to not share my project info. I started with a new WSL session and launched code from there. I built a minimal python venv using conda then added a foo.py and test/test_foo.py file with just your basic guts. I ran the configure tests function.

Then when I pressed play on the test I got the file not found error. Also the annotations are missing from the test_foo.py file.

Error message in the OUTPUT Python Test Log:

============================= test session starts ==============================

I just validated that screen shot got posted well. I believe you can see every line of my project there, both py files, and the settings.json for the workspace.

Environments I've tried this project in:
Windows running remote - ssh connection to linux - FAILED
Windows running WSL Ubuntu 18.04 - FAILED
Linux - PASSED

Interestingly, this works fine if I press the Play All button at the top, it's only when I Play an individual test that I get the error.

#6881 may be related.

I have the same error running on macOS. I can execute pytest from the command line perfectly fine, but cannot run in vs code.

Hey Alex, I'm still not 100% clear on why the above was failing. But in another project I have, I was using symlinks and this caused quite a few issues. Once I moved away from all the symlinking, all the VSCode test features started working.

Todd Jones (@toddljones)

Thanks Todd Jones (@toddljones) I'll give it a shot

I have the same error in here. When I press the button "Run All Tests" it works fine. But when I try to run individual tests I received the error ERROR: file or directory not found: ./root-ceua/tests/test_admin.py::test_update_lineage interestingly the path is correct.

Having the exact same issue, works for 'All Tests' but not individually.

Having something similar to this. In our case turns out that it relates to the fact that we are using symlink as workspace dir. And this vscode-python extension's pytest test discovery hits a pytest issue that it gets wrong info about test file paths when workspace dir is a symlink. See also ticket I created to pytest pytest-dev/pytest#9008

Starting with 2021.9 (which will be released this week) we have new system manage test ux. Please try this out with that.
