How to silence unwanted warnings?

Before submitting a topic, please confirm the following

I have searched for similar issues before creating this topic.
I have verified that my repository is using the Codecov GitHub app, if using GitHub
I have validated my codecov.yaml configuration file.
I have filled out the below sections to the best of my ability.

Description

Bokeh server is an application that runs other Python scripts. As part of our testing we generate deliberately mal-formed Python files to maintain behaviors under error situations. Codecov is noticing these files and generating many spurious unwanted warnings in our CI logs:

/usr/share/miniconda3/envs/bk-test/lib/python3.11/site-packages/coverage/report.py:87: CoverageWarning: Couldn't parse '/home/runner/work/bokeh/bokeh/build/tmp/tmp1pi1schf.py': No source for code: '/home/runner/work/bokeh/bokeh/build/tmp/tmp1pi1schf.py'. (couldnt-parse)
  coverage._warn(msg, slug="couldnt-parse")

I am looking for a way to silence these. I had tried using ignore (see below) but apparently that is not the correct approach.

Expected Results

I tried to slience these warnings by adding ignore to our codecov.yml, per these instructions. Following the paths in the warnings, I added the pattern "**/build/tmp/tmp*.py". The resulting value in the codecov.io site was

ignore:
- (?s:.*/build/tmp/tmp[^\/]+\.py.*)\Z

I expected (hoped) that ignoring the file would also result in suppressing any warnings about the ignored files.

Actual Results

After adding the ignore block, the warning messages still persist in CI logs.

Additional Information

Is there a different mechanism to silence or quiet specific warnings? I did not turn up anything.

@bryevdv this is not a Codecov issue, the errors come from running pytest --cov=bokeh --cov-report=xml --color=yes tests/unit which occur before you upload coverage reports to Codecov. I would check the pytest or pytest-cov docs.

Yes it was :man_facepalming: (thank you!)
