Q:

Using local imports in Pytest

I have never really fully understood how packages are handled in Python and I'm having a problem with that right now. But googling doesn't seem to help as I find the topic really confusing.
I have a project with this structure:
project_name/
    src/
        main.py
        utils/
            string_utils.py
    tests/
        test_string_utils.py

I am using Pytest for running unit testing and currently inside the  "test_string_utils.py" file I have the following:
from ..src.utils.string_utils import StringUtilsClass

But I go to the folder "project_name" and try to run tests with any of this command I get errors:
$ pytest tests/

ValueError: attempted relative import beyond top-level package
I know about the -m argument for python, but it seems that  running "pytest -m" has a completely different behavior.
How can I solve this? Am I using the wrong folder architecture? I don't think what I'm building should be a pip package (which would simplify imports) 

A:

did you try : from src.utils.string_utils import StringUtilsClass without .. before src?
or from string_utils import StringUtilsClass
