Pytest uses wrong base directory for tests selection

[SanctusAnimus]

Suppose i have a following structure, inside Pycharm Project directory

ot3_webserver
| - app (folder with code src)
| - ot3_tests
    | - conftest.py
    | - test_routers
        | - test_redis.py

ar_webserver
| - app (folder with code src)
| - tests
    | - conftest.py
    | - test_routers
        | - test_redis.py

ar_webserver was made initially, and test code was made and written here.
Later tests were migrated (with some adjustments) to ot3_webserver

In ar_webserver tests still work correctly.
However when i start them in ot3_webserver i get following output:

test_routers/test_battle_pass_router.py::TestBattlePassRouter::test_redeem_bp_rewards <- ..\tests\test_routers\test_battle_pass_router.py

I can't find anything in regards to this <- arrow, why it happens and how to prevent that at all.

Inherently, all error messages are pointing towards tests of other projects, like so:

..\..\ar_webserver_template\tests\test_routers\test_pages\test_statistics.py:22 - ...

Pycharm seems to launch them with correct working directory set, via

C:\Users\den_k\PycharmProjects\ot3_webserver\venv\Scripts\python.exe C:/Users/den_k/AppData/Local/JetBrains/Toolbox/apps/PyCharm-P/ch-0/231.8770.66/plugins/python/helpers/pycharm/_jb_pytest_runner.py --path C:\Users\den_k\PycharmProjects\ot3_webserver\ot3_tests -- -s -x -m "not payments" 
Testing started at 19:19 ...

But then collected tests all reference external folder

test_routers/test_battle_pass_router.py::TestBattlePassRouter::test_set_redeemed <- ..\tests\test_routers\test_battle_pass_router.py 
test_routers/test_battle_pass_router.py::TestBattlePassRouter::test_create_trial_subscription <- ..\tests\test_routers\test_battle_pass_router.py 
test_routers/test_gift_code_router.py::TestGiftCodeRouter::test_prepare_data <- ..\..\ar_webserver_template\tests\test_routers\test_gift_code_router.py 

How can i stop pytest from seeking folders above project root?

[SanctusAnimus]

As an added detail, it does that only for identical test copies (files that were not changed)
Adding a single comment with whitespace is enough to force it to use test from desired directory

Still have no idea why it even tries to discover tests from folders above working directory though

[RonnyPfannschmidt]

This looks like a import path conflict, either add loads of __init__.py files to ensure pytest can leave sys. Path alone for imports, or try the importlib import mode

[SanctusAnimus]

I believe i have __init__.py pretty much everywhere, including every project folder and tests folders themselves.

Can you elaborate to importlib import mode?

[SanctusAnimus]

Ok i actually found it and enabled, and it still tries to import wrong files, but now raises when doing so

If i edit the file to remove said error it'll be gone, but editing file worked without changing import mode anyway

Could it be because of following options of Pycharm messing with Path?

They are enabled by default, but removing marking from tests folders (they were marked as Test source previously) doesn't seem to do anything, unless i have to reset it somehow
And unchecking them breaks entire test suite cause it fails to find app and other modules located on the same level as tests folder is

[RonnyPfannschmidt]

I'm unfamiliar with the path handling of pycharm, personally I absolutely avoid letting it mess with pythonpath

[SanctusAnimus]

Well, for now adding # ot3_webserver as a first line to every test file of ot3_webserver project test suite resolved the issue.

Kinda dirty, but as long as it works i guess
