No, you're mixing concerns.

class MyTestCase(TestCase):
def check_response(self, response):
self.assertContains(response, ....)
def checked_get(self, *args, **kw):
r = self.client.get(*args, **kw)
self.check_response(r)
return r
class SpecificTest(MyTestCase):
def test():
r = self.checked_get(...)
...
