Description

This example shows how you can connect to an existing database and use it for your tests. This example is trivial, you just need to disable all of pytest-django and Django’s test database creation and point to the existing database.

This is achieved by simply implementing a no-op django_db_setup fixture.

Put this into conftest.py:

# conftest.py
# DATABASE_URL=postgresql://<username>:<password>@XX.0.XX.XX:5432/db_intranet

import pytest
from django.conf import settings

@pytest.fixture(scope="session")
def django_db_setup():
    settings.DATABASES["default"] = {
        "ENGINE": "django.db.backends.postgresql",
        # Test database
        "HOST": "XX.0.XX.XX",
        "NAME": "db_intranet",
    }
