How to use session in TestCase in Django?

Question

I would like to read some session variables from a test (Django TestCase)

How to do that in a clean way ?

def test_add_docs(self):
    \"\"\"
    Tes         


        

Answer 1

If testing my django project with pytest, I can not see any modifications to the session that are made in the view. (That is because the Sessions middleware doesn't get called.)

I found the following approach to be useful:

from unittest.mock import patch
from django.test import Client
from django.contrib.sessions.backends import db

def test_client_with_session():
    client = Client()
    session = {}  # the session object that will persist throughout the test
    with patch.object(db, "SessionStore", return_value=session):
        client.post('/url-that-sets-session-key/')

        assert session['some_key_set_by_the_view']

        client.get('/url-that-reads-session-key/')

This approach has the benefit of not requiring database access.
