Currently, I am using lxml. More dependencies but it's the cleanest
method I've found currently.
I use it like that:
from django.test import TestCase
from lxml import etree
class FormTest(TestCase):
def test_input(self):
response = self.client.get('/accounts/login')
self.assertEqual(response.status_code, 200)
doc = etree.HTML(response.content)
self.assertEqual(len(doc.findall('.//input[@name="username"]')), 1)
