Having this target,

python_tests(
    name="tests",
    dependencies=[":testdata"],
    sources=[
        "tests/test_*.py",
        "tests/foo.py",
    ],
)

if

foo.py

doesn’t exist, then when running

./pants test

command, we’ll see a warning

[WARN] Unmatched glob from project/project:tests's `sources` field:
"project/project/tests/foo.py"

Is it possible OOTB to get warnings about unmatched globs without triggering running tests across all

BUILD

files and then grepping the output for

[WARN] Unmatched glob

?

This would be very handy to have as a repository lint step in CI to avoid failing the testing step (when all tests pass but there are unmatched globs)

it’s of course possible to collect the issues and present them later, but it would be very helpful to be able to validate sources as a separate goal

And it will error on those unmatching globs

I think it will error on the first one, not collect them all, so you might have to keep running it until it passes
