How do I select a sub-folder as a directory containing tests in Python extension for Visual studio code

Question

I am using VScode with python code and I have a folder with sub-directories (2-levels deep) containing python tests.

When I try "Python: Discover Tests" it asks for a test framework (selected pytest) and the directory in which tests exist. At this option, it shows only the top-level directories and does not allow to select a sub-directory.

I tried to type the directory path but it does not accept it.

Can someone please help on how to achieve this?

I solved it by putting this in my settings.json:

"python.testing.cwd": "${workspaceFolder}/my-project/all-tests/unit-tests"

In the GUI, the setting name is "Python > Testing: Cwd".

If you then get the error No file or directory "unit-tests", try this:

1. Open the test configuration dialogue (Ctrl/Cmd + Shift + P -> "Python: Configure Tests")
2. Select pytest or unittest
3. Select . (Root Directory) - Earlier I had selected the unit-tests directory instead

If it still isn't working, you might be running into this open bug with ${workspaceFolder}.

If it still isn't working, open up the "Output" window and select "Python" to see more info.
