Actual behaviour

Debugging tests shows an error notification even though the test passes:

Steps to reproduce:

[NOTE: Self-contained, minimal reproducing code samples are extremely helpful and will expedite addressing your issue]

1. Clone this project: https://github.com/luabud/pvscc-logo
2. Create a virtual environment and install the dependencies
3. Run Python: Configure Tests, select pytest and then . for root directory.
4. Open tests.py and change line 13 to str instead of io.BytesIO
5. Run the test and see that it passes
6. Now click to debug this test
7. Watch the error notification pop up even though the debugger session started properly and everything.

Exactly same problem on macOS Big Sur. And I use Pylance and I am NOT in any experiment group. I've seen this problem in different projects and also on VSCode remote (Linux).

If I use the bug icon on Test Explorer view, only error "There was an error in running the tests. Source: Python (Extension)" is shown.

If I use cmd+shift+P (Command Palette) -> Python: Debug Test Method... I got:

Error: Error: unsupported status (Discovering)

and

Command 'Python: Debug Test Method ...' resulted in an error (Running the contributed command: 'python.selectAndDebugTestMethod' failed.)

From my launch.json:

        {
            "name": "PyTest Debug",
            "type": "python",
            "request": "test",
            "justMyCode": true,
            "console": "integratedTerminal",
            "env": {
                "PYTEST_ADDOPTS": "--no-cov",
                "APP_ENV": "prod",
            }
        }

Just started hitting this error as well. Debugging tests is still working as expected, but the error is showing up.

The python extension auto-updated in my VS Code devcontainer. The problem seems to have been resolved by this version: v2021.4.765268190

I can confirm I don't see any issues anymore with:

[niccolomineo]

Not here, I still have that error.

[Maverickzero]

I'm running version 1.56.0 and I'm getting this error every time I try to run a single test. When I try to "run all tests" it does work. Pytest version is 6.2.2.

[aaraney]

@Maverickzero, I can confirm the same behavior on 1.56.1.

I'm on 1.56.2 and also saw "Error: Error: unsupported status (Discovering)" today - even when normally running a single test, without debugging.

[Anatoly-Makarevich]

I got this issue today, my tests passed (seen in output), but the last line of the output was Error: Error: unsupported status (Idle)

FYI, just restarting VSCode seemed to fix this. Probably something with an underlying process getting stuck.

[brunakov]

When I change a test and run it without re-Discover tests I get :
Error: Error: unsupported status (Running)

This should be addressed by #16769
