Testing Django view context items

You can test for the presence of particular context items in the following manner:

from django.tests import TestCase
from my_app.models import TestModel

class MyTest(TestCase):
	
	def test_context_item(self):
		test_item = TestModel.objects.create()
		
		response = self.client.get('some/url/')
		
		self.assertEqual(response.context['context_key'], test_item)

test_item is the item we are trying to find in the context of the view that is called by 'some/url'. We can access the context dictionary of the view created the response with the code response.context['context_key'], where 'context_key' is the context item you are testing for.
