Django - testing view which works with ajax requests

Question

I want to test that my view returns correct json after processes. here is my view:

@login_required
@require_POST
def xxx_view(request):
    if 'post_id' in request.POST:
        post_id = request.POST['post_id']

        post = Post.objects.get(id=post_id)
        post.order = 2
        post.save()

        json_dump = simplejson.dumps({'new_title': post.order,})
        return HttpResponse(json_dump, mimetype='application/json')
    else:
        return HttpResponse('oups')

this works correctly. Here is what i ve tried for testing:

from django.test import TestCase
from django.test.client import Client
from django.utils import simplejson
from app.models import *

c = Client()
class CustomTests(TestCase):
    def test_xxx(self):
        json_data = simplejson.dumps({'post_id': 1,})

        response = client.post('/content/vote/', json_data,
                content_type='application/json',
                HTTP_X_REQUESTED_WITH='XMLHttpRequest')
        self.assertEqual(response.status_code, 302) # this is OK.
        self.assertEqual(response.content, 2) # but this fails.

response.content returns empty string.

Thank you.

It looks like your login_required decorator is redirecting your unauthenticated user. Make sure you create a test user and log that user in using test client login method
