Pytest Discovery Error in VSCode after renaming folder

I have pytest configured and working in VSCode, with automatic test discovery enabled.

But renaming a folder in the project that contains tests breaks both those tests and auto-discovery, instead producing a Pytest Discovery Error. How can I get the Testing to fully refresh – removing tests under the old folder name and adding those in the new name?

Simple steps to reproduce problem:

1. Under project folder hello is a folder foo containing x.py and test_x.py.
2. Open the VSCode Testing sidebar and configure to run pytest.
3. Now the Testing pane shows the test hierarchy hello >> foo >> test_x.py >> test_*
4. In the VSCode Explorer pane rename foo to bar.
5. Refresh Testing >> Test Explorer, and/or re-run all tests.

Result:

• None of the tests under hello >> foo work because there is no hello/foo.
• I can't get hello >> bar >> ... to appear in the Testing pane.
• Test Explorer also contains a Pytest Discovery Error [hello] (with details pasted below).

How can I force the Testing configuration to refresh so that it removes the hello >> foo tests and adds the hello >> bar tests?

Verbose output after renaming foo to bar and refreshing/re-running tests:
