best way to create example project in a django plugin test suite-CodePudding

This may be a simple question, but I can't wrap my head around it. Given I make a Django plugin app, lets name it foo, which adds some database features, that other apps can use (e.g. models that must be inherited), and I want to add tests for that app. Structure:

foo/
  apps.py
  models.py
tests/
  test_foo_basic.py
  test_bar.py
  ...
setup.py
README.md
...

The project is no full Django application, as it is an plugin app for others. So I need to create a fake Django project within the testing directory, with at least one app, which defines some models that inherit from foo.models.<some_model> and test it, right?

Is that the only way? It seems a but much for me.

If so, it's ok for me to give me the answer "it is so". And I'll accept ;-) If not, please tell me I am complicated and show me something easier, a pytest plugin etc.? For testing, I need a

I found out myself, after much struggle.

According to pytest-django docs, you can use pytest_configure() in conftest.py to set up a "pseudo" Django environment for such cases:

# conftest.py

import django
from django.conf import settings


def pytest_configure():
    settings.configure(
        DATABASES={
            "default": {
                "ENGINE": "django.db.backends.sqlite3",
                "NAME": ":memory:",
            }
        },
        INSTALLED_APPS=[
            "django.contrib.auth",
            "django.contrib.contenttypes",
            "django.contrib.sessions",
            "django.contrib.messages",
            "django.contrib.staticfiles",
            "django.contrib.sites",
            "your.app"
        ],
    )
    django.setup()

This way, you need no pytest.ini, no DJANGO_SETTINGS_MODULE env, and the best is: ** You need no complete dummy Django project`

It doesn't help if you need to test project features like module loading, etc. But for simple unit tests, this works perfectly.
