Code:
    def test_view_object_with_unsafe_text(self):
        """Ensure that JobButton text can't be used as a vector for XSS."""
        self.job_button.text = '<script>alert("Hello world!")</script>'
        self.job_button.validated_save()
        response = self.client.get(self.location_type.get_absolute_url(), follow=True)
        self.assertEqual(response.status_code, 200)
        content = extract_page_body(response.content.decode(response.charset))
        self.assertNotIn("<script>alert", content, content)
        self.assertIn("&lt;script&gt;alert", content, content)

        # Make sure grouped rendering is safe too
        self.job_button.group = '<script>alert("Goodbye")</script>'
        self.job_button.validated_save()
        response = self.client.get(self.location_type.get_absolute_url(), follow=True)
        self.assertEqual(response.status_code, 200)
        content = extract_page_body(response.content.decode(response.charset))
        self.assertNotIn("<script>alert", content, content)
        self.assertIn("&lt;script&gt;alert", content, content)
