Writing tests for the Django admin with pytest-django | Simon Willison’s TILs
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/",
