Django Unit Testing Assert error

this is on Django 1.6

def test_perfil_password_validates_new_passwords(self):
    self.client.login(username='[email protected]', password='test')
    resp = self.client.post('/perfil/password/',
                            json.dumps({'oldpassword': 'test',
                                        'newPassword1': 'wrong',
                                        'newPassword2': 'nuevo'}
                                       ),
                            'text/json',
                            HTTP_X_REQUESTED_WITH='XMLHttpRequest')
    self.assertEqual(resp.status_code, 400)

THIS WORKS and this is the output:

Creating test database for alias 'default'... .
---------------------------------------------------------------------- 
Ran 1 test in 0.273s

OK

Now if i add this extra assert

self.assertContains(resp, '"error":')

Creating test database for alias 'default'... F
======================================================================

I have no clue why this expects 200, or why does it give me an assertionError I can even print the content, so it's there. What am I missing?

Looking at the docs, it appears that the assert takes the expected status code, which is defaulted to 200:

TestCase.assertContains(response, text, count=None, status_code=200, msg_prefix='', html=False)

I'm going to go out on a limb and say, your assert should look like:

self.assertContains(resp, '"error":', status_code=400)
