Test discovery command does not call the python interpreter

[remko-bw]

Type: Bug

Behaviour

Expected vs. Actual

Expected: When I open the Test Explorer and trigger test discovery, it should discover tests.
Actual: No tests are discovered.

When I look in the Python output, I can see that the command to invoke pytest is not correct.

This is what I see:

> ./.venv -m pytest -p vscode_pytest --collect-only

This is what I expect to see:

> ./.venv/bin/python -m pytest -p vscode_pytest --collect-only

Steps to reproduce:

Open test explorer, and click the 'Reload' button.

Diagnostic data

Can you share your settings.json and launch.json?

I alo have a problem with tests discovery.
Output from console

Nothing really happens, when I open testing side panel. Only those logs.
