Cannot create coverage file locally on Mac

1. tox -e dev
2. source venv/bin/activate
3. tox

Tests works fine until 98% after which I get an error:

[stijnvanhoey]

@peterdesmet damn, It seems that it does not relate to the unit tests as I see in your output:

...
tests/test_vpts_csv.py::TestVptsCsvV1SupportFun::test_check_source_file_wrong_file PASSED                                                                                 [100%]

and it also works in the Mac github action.

but rather with creating the coverage results. Can you retry with the .coverage.Peters-MacBook-Air.local.50618.245710-journal or other .coverage files/folders removed inside your repo folder?

[peterdesmet]

Running tox from the repository root creates 66 coverage files. One named .coverage and 65 named .coverage.Peters-MacBook-Air.local.<integer>.<integer>

• Removing those files and running tox again results in the same error.
• Removing those files and the committed (!) .coveragerc results in:

But with an indication that the tests have now succeeded.

This issue does not occur in the CI: https://github.com/enram/vptstools/actions/runs/4561907488/jobs/8048440757#step:5:109

Note, I'm using tox 4.4.8, while the CI uses tox 3.27.1 (set fixed here)

[stijnvanhoey]

@peterdesmet when working on the CI I encountered a similar issue. Can you try to use tox -e py instead of just tox? This runs tests only on current py-version instead of trying all of the enlisted and skipping when not available. The latter introduced an error on the .coverage in CI which I solved there with -e py parameter.

[peterdesmet]

Started from a fresh repo and followed:

tox -e dev
source venv/bin/activate
tox -e py # rather than tox

Unfortunately, the error remained:
