Testing template used

The template used for a specific URL pattern can be tested by using Django's test client. The test client can be used as an attribute of Django's TestCase class. It is used to request a URL pattern, and it then uses this URL pattern to find the appropriate view. If it finds a view for the URL, it executes the view, giving us a response.

from django.test import TestCase


class MyTest(TestCase):
	
	def test_template_used(self):
		response = self.client.get('/')		# Requesting root url
		self.assertTemplateUsed(response, 'home.html')	# checks response template

Because the client has to fetch the appropriate view for the provided URL, this method also implicitly tests that our URL pattern uses the correct view.
