Question

how do i assert that F appears only once in ABCDEF?

I used assertEqual but django states that:

Traceback (most recent call last):
  File "/Users/jorrit/virtualenvs/voetbabbel/voetbabbel/apps/mass_mailer/tests.py", line 61, in test_create_mailing_list
    self.assertContains(p.user.email,"@", 1, status_code=200)
  File "/Library/Python/2.7/site-packages/django/test/testcases.py", line 419, in assertContains
    self.assertEqual(response.status_code, status_code,
AttributeError: 'unicode' object has no attribute 'status_code'

and my code in the test:

self.assertContains(p.user.email,"@", 1)

As Chris says, this isn’t what assertContains is for. You can use one of the standard assertions:

self.assertTrue(p.user.email.count('@') == 1)
