could not make test explorer work

[chanansh]

Type: Bug

Why is it so hard to make test explorer work with pytest?
I have simple project structure

project_root/
   src/
   tests/

my settings are:

{
    "python.testing.pytestArgs": [
        "tests"
    ],
    "python.testing.unittestEnabled": false,
    "python.testing.pytestEnabled": true,
    "python.analysis.autoImportCompletions": true,
    "python.analysis.extraPaths": [
        "src", "tests"
    ],
    "python.testing.nosetestsEnabled": false,
}

Hello! Sorry to hear it isn't working out of the box! Could you include a layout of your project and your logs from the python output channel? For your logs, can you first set your log level to trace via theDeveloper: set log level command in the command palette? With these I can better help figure out what might be going wrong. Thanks

Closing as this issue has been inactive for over a month and requires information from the poster. Please comment with the required information if this is not resolved and I can reopen. Thanks

I found the solution was to add this to the pyproject.toml

[tool.pytest.ini_options]
pythonpath = "src"
addopts = "-s"

make sense one could indicate in vs code what is the code root (in my case src) so that the pythonpath includes it (like in PyCharm)

@chanansh, glad you found a fix! We are moving to having a more obvious way to set env vars, do you think something like this would have made this more discoverable as a user? #21845

Curious on any input you have that might have made setting this up go smoother as we are always trying to improve this experience, let me know if you have any thoughts

Thanks!
