Does Pants pay attention to the

conftest.py

file, or any part of it? Thanks...

Can you be more specific? 🙂 Pants is aware of conftest files (see

python_test_utils

target) and auto-infers them up the chain

In particular the

collect_ignore

list.

I don't think so. The collect_ignore docs. I've created a minimal repro here: https://github.com/AlexTereshenkov/example-python/pull/2/files with `collect_ignore = ["translator"]`:

$ ./pants --no-local-cache test ::
✓ helloworld/greet/greeting_test.py:tests succeeded in 0.20s.
✓ helloworld/translator/translator_test.py:tests succeeded in 0.17s.

$ pytest helloworld

I am afraid you'd have to pass arguments to

pytest

to filter the tests, please see https://www.pantsbuild.org/docs/reference-pytest#args
