Are you opening SMTP and POP3 sockets?? If you are not developing that layer itself, just use Django's built- in mock system. Here's my favorite assertion for it: def assert_mail(self, funk): from django.core import mail previous_mails = len(mail.outbox) funk() mails = mail.outbox[ previous_mails : ] assert [] != mails, 'the called block should produce emails' if len(mails) == 1: return mails[0] return mails You call it a little bit like this: missive = self.assert_mail( lambda: mark_order_as_shipped(order) ) Then you can use assert_contains on the missive.body, to see what mail got generated. That's what you are actually developing, so your tests should skip any irrelevant layers, and only test the layers where you yourself might add bugs. -- Phlip http://penbird.tumblr.com/ |
