This repository is a minimal reproducible example of Pants not enforcing the [run].omit=*test* option in .coveragerc when [coverage-py].global_report=true is enabled in pants.toml.

Bootstrap Pants:

$ curl -L -o ./pants https://pantsbuild.github.io/setup/pants && \
chmod +x ./pants

Running test goal in Pants with [test].use-coverage option enabled, [run].omit=*test* enabled but [coverage-py].global_report=true disabled (as it is in this repo):

$ ./pants test ::

Results in non-test source files being reported on as so:

Name                                    Stmts   Miss  Cover
-----------------------------------------------------------
minimalcov/minimalcov/__init__.py           0      0   100%
minimalcov/minimalcov/src/__init__.py       0      0   100%
minimalcov/minimalcov/src/foo.py            1      0   100%
-----------------------------------------------------------
TOTAL                                       1      0   100%

Activating global reporting by uncommenting [coverage-py].global_report=true in pants.toml shows the issue: Pants should inherit configuration options for coverage.py from .coveragerc and also omit test files in the same way but this does not happen.

Running the test goal again with [coverage-py].global_report=true:

$ ./pants test ::

Results in:

Name                                      Stmts   Miss  Cover
-------------------------------------------------------------
minimalcov/minimalcov/__init__.py             0      0   100%
minimalcov/minimalcov/src/__init__.py         0      0   100%
minimalcov/minimalcov/src/foo.py              1      0   100%
minimalcov/minimalcov/tests/__init__.py       0      0   100%
minimalcov/minimalcov/tests/test_foo.py       3      3     0%
-------------------------------------------------------------
TOTAL                                         4      3    25%

This use-case is valuable for identifying target directories that have source files but have yet to be given test files.
