Python - Running unit and integration tests with standard directory structure

Question

I have the following directory structure, as recommended in the pytest docs :

setup.py
src/
    mypkg/
        __init__.py            
        app.py
        view.py
tests/
    __init__.py                 
    unit/
        __init__.py
        app_test.py
    integration/
        __init__.py
        app_test.py

All init.py files are empty for now.

And setup.py contains:

from setuptools import setup, find_packages

setup(name="mypkg", packages=find_packages())

I want to use pytest for testing.

The command i use to run tests is

 pytest ./tests/unit/app_test.py

How do I import app.py into app_test.py and make sure my tests can run without issue.

Ideally, I want a pythonic/clean way to resolve this, not a hack.

I've stumbled upon many questions in regards to this, such as :
How do I run all Python unit tests in a directory?

Running unittest with typical test directory structure

But somehow I can't get it to work with my use case. Can anybody pinpoint in the right direction ?

Alright I got what i was looking for with :

setup.py
src/
    main.py
    __init__.py

tests/
    __init__.py                 
    unit/
        __init__.py
        app_test.py
    integration/
        __init__.py
        app_test.py

In app_test.py simply,

  import src.main

Running tests with :

pytest  ./tests/unit/app_test.py
