Using Basic HTTP access authentication in Django testing framework

For some of my Django views I've created a decorator that performs Basic HTTP access authentication. However, while writing test cases in Django, it took me a while to work out how to authenticate to the view. Here's how I did it. I hope somebody finds this useful.

Solution 1:

Here's how I did it:

from django.test import Client
import base64
auth_headers = {
    'HTTP_AUTHORIZATION': 'Basic ' + base64.b64encode('username:password'),
}
c = Client()
response = c.get('/my-protected-url/', **auth_headers)

Note: You will also need to create a user.

Solution 2:

In your Django TestCase you can update the client defaults to contain your HTTP basic auth credentials.

import base64
from django.test import TestCase

class TestMyStuff(TestCase):

    def setUp(self):
        credentials = base64.b64encode('username:password')
        self.client.defaults['HTTP_AUTHORIZATION'] = 'Basic ' + credentials

Solution 3:

For python3, you can base64-encode your username:password string:

base64.b64encode(b'username:password')

This returns bytes, so you need to transfer it into an ASCII string with .decode('ascii'):

Complete example:

import base64

from django.test import TestCase

class TestClass(TestCase):
   def test_authorized(self):
       headers = {
           'HTTP_AUTHORIZATION': 'Basic ' + 
                base64.b64encode(b'username:password').decode("ascii")
       }
       response = self.client.get('/', **headers)
       self.assertEqual(response.status_code, 200)
