描述

codecov/codecov-cli enhancement Medium

Describe the bug
In my project, I configured coverage.py using pyproject.toml to

  • write all files into a test-files folder (idk if that’s relevant)
  • skip coverage for if TYPE_CHECKING: blocks

The reported coverage reflects that (see table below), and when I run coverage xml, the test-files/coverage.xml file is also correct.

Name Stmts Miss Cover ------------------------------------------------------------------ src/fast_array_utils/__init__.py 4 0 100% src/fast_array_utils/_patches.py 2 0 100% src/fast_array_utils/conv/__init__.py 3 0 100% src/fast_array_utils/conv/_asarray.py 25 3 88% src/fast_array_utils/conv/scipy/__init__.py 3 0 100% src/fast_array_utils/conv/scipy/_to_dense.py 12 0 100% src/fast_array_utils/stats/__init__.py 3 0 100% src/fast_array_utils/stats/_sum.py 33 0 100% src/fast_array_utils/types.py 25 2 92%
------------------------------------------------------------------ TOTAL 110 5 95%

But when the codecov CLI runs coverage xml via its coveragepy plugin, the lines are not skipped and codecov reports a 82.87% coverage instead of the expected 95.45% (see codecov report for the linked run below)

See also Additional context below for a workaround I’m using

To Reproduce

  1. set coverage.py’s report.exclude_also setting in a pyproject.toml to ignore some lines
  2. collect coverage in .coverage file and run coverage xml
  3. run codecov CLI’s upload (which will re-generate the XML)
  4. compare the XML you created with the one codecov’s CLI created

Expected behavior
either

  • coverage xml run from the codecov CLI uses the same config as when I run it, or
  • when the file passed via --file already exists, have the codecov CLI skip running coverage xml

Regression
This probably worked using the old coverage PyPI package, but IDK.

Additional context
I can manually work around this by generating the XML myself and then deleting the test-files/.coverage file, but this should be fixed on your side.

See https://github.com/scverse/fast-array-utils/pull/29 for the workaround, which results in the correct coverage of 95.45% being reported.
