VS Code unable to detect tests using environments and hatch

Issue with VS Code not using the correct interpreter for a project and not

In our team some have this problem and for some it justworks. detecting pytest tests.

Background:

• system uses Python 3.10 (Ubuntu 22.04)
• pyenv is installed and provides 3.12.2

u30576@DCL0004:~$pyenv versions
* system (set by /home/u30576/.pyenv/version)
  3.12.2

We have different Python projects (we use hatch) and we are moving them over to 3.12.x.

We therefore have to select interpreter choose workspace and then pick among the following:

If I choose any of the 3.12.2, including topsky-stimulator, then VS Code won't be able to detect pytest tests due to pytest library not being installed

1. VS Code can't expect the "clean install of 3.12.2 pyenv" to include pytest as this project might use another version
2. VS Code can't expect the default environment (topsky-stimulator) to include pytest as those are only needed for testing (hence the test environment)
3. The hatch project has two environments in addition to the default: lint (black, flake8) and test (pytest etc). These are shown for 3.10.12 but not for 3.12. Why?

The tests will be detected if I pip install pytest to 3.12.2 (clean and/or topsky-stimulator), but it's the wrong way to go about it.

I've cleared cached and restarted language server for Python but same issue. We checked with a colleague now and it works for him. Our computer are configured via Ansible, including VS Code, but there is obviously some difference.

I "Reset All Windows" and now I get the Run/Debug Dropdown:

1. Run -> Add Configuration still does not show Python alternatives
2. Select Interpreter does not all available environments defined in hatch project

That's by design as discovery is implemented for pytest as a pytest plug-in, and so we need pytest to run. And we don't ship pytest w/ the extension as pytest has an API that your code relies on, and so we can't assume whatever version we ship will match the version you code against.

2. Select Interpreter does not all available environments defined in hatch project

Can you open an issue using "Report Issue" about the missing environments?
