Writing tests for the Django admin with pytest-django

I'm using pytest-django on a project and I wanted to write a test for a Django admin create form submission. Here's the pattern I came up with:

from .models import Location import pytest def test_admin_create_location_sets_public_id(client, admin_user): client.force_login(admin_user) assert Location.objects.count() == 0 response = client.post( "/admin/core/location/add/", { "name": "hello", "state": "13", "location_type": "1", "latitude": "0", "longitude": "0", "_save": "Save", }, ) # 200 means the form is being re-displayed with errors assert response.status_code == 302 location = Location.objects.order_by("-id")[0] assert location.name == "hello" assert location.public_id == "lc"

The trick here is to use the client and admin_user pytest-django fixtures (documented here) to get a configured test client and admin user object, then use client.force_login(admin_user) to obtain a session where that user is signed-in to the admin. Then write tests as normal.

Using the admin_client fixture

Even better: use the admin_client fixture provided by pytest-django which is already signed into the admin:

def test_admin_create_location_sets_public_id(admin_client): response = admin_client.post( "/admin/core/location/add/", # ...

Before finding out that this was included I implemented my own version of it:

import pytest @pytest.fixture() def admin_client(client, admin_user): client.force_login(admin_user) return client # Then write tests like this: def test_admin_create_location_sets_public_id(admin_client): response = admin_client.post( "/admin/core/location/add/", # ...
