[Python] In a uv-created venv, the VS Code Integrated Debugger is not activating when clicking...

I am migrating a Django project from Pipenv to uv.

My development environment is a VS Code Dev Container. Everything worked as expected when using Pipenv.

I have a problem where the integrated debugger will not activate when I attempt to debug pytest unit tests.

I set a breakpoint in the unit test, and clicked "Debug Test". The test runs, but the debugger is never activated.

Test Results: Finished running tests!

Debug Console: shows what I'd expect from running a pytest unit test.

Python: Select Interpreter is set to my virtual environment's python.

I have debugpy installed.

I tried to manually get the debugger to activate.

In one python session:

>>> import debugpy; debugpy.listen(5678); debugpy.wait_for_client()
('127.0.0.1', 5678)


another python session:

uv run python -m pytest src/nexxus/tests/test_views.py::TestLegacyClientView::test_legacy_client_view_returns_active_servers


The test runs, but the debugger is never activated.

I am using:

• Visual Studio Code 1.99.0
• Python 3.11.2
• debugpy 1.8.13

Any help would be appreciated.

Thanks.

EDIT:

It is one of these options from the pytest.ini that is breaking things

[pytest]
# Test coverage options
addopts =
--cov=.
--cov-branch
--cov-fail-under=75
--cov-report=html
--cov-report=term-missing
--import-mode=importlib
