Q8: When I run

./pants test tests/common:tests

, pytest gets executed but all tests immediately fails with import errors because there is no 3rd-party dependencies installed.

tests/common/BUILD

simply consists of

python_tests(name="tests")

and its siblings include

conftest.py

and

test_xxx.py

stuffs. How do I let pants install 3rd party dependencies for tests?

ok, I got it working with the root-level

requirements.txt

and

BUILD

with

python_requirements(name="reqs", source="requirements.txt")

which are referenced as

//:reqs

in the dependencies of

src/ai/backend/common:lib

which is also referenced by

tests/common:tests

it seems that Python got confused with import from

ai.backend.common.redis

and

tests/common/redis/

...

i had resolved this issue by adding

__init__.py

to the tests directory, but it seems that this might not be recognized..

it could be simpler if you define requirements.txt under

3rdparty

folder at the root of your repo. Check pants own repository. This is a "standard" location known to pants. You wouldn't need to mention

requirements.txt
