You can use a file backend for sending emails which is a very handy solution for development and testing; emails are not sent but stored in a folder you can specify!
Django test framework has some built in helpers to aid you with testing e-mail service.
Example from docs (short version):
from django.core import mail from django.test import TestCase class EmailTest(TestCase): def test_send_email(self): mail.send_mail('Subject here', 'Here is the message.', 'firstname.lastname@example.org', ['email@example.com'], fail_silently=False) self.assertEqual(len(mail.outbox), 1) self.assertEqual(mail.outbox.subject, 'Subject here')
