Lots of red text when running `tox` on a fresh cookie.

[samcunliffe]

Describe the Bug

During the workshop we ran tox on a demo package. There were a lot of errors possibly related to coverage?

To Reproduce

Cookiecut a fresh cookie.

uv venv
source .venv/bin/activate
uv pip install -e ".[dev,test]"
which tox
tox

Expected Behaviour

tox should run tests in all supported Python versions with nice comforting green text. And no red text.

Actual Behaviour

Not errors but warnings, but yes, very RED warnings (maybe my zsh theme?).

[samcunliffe]

Confirmed. What @Saransh-cpp said.

Possible solution: have some dummy code and have the tests executed the dummy code.
