How to test auto_now_add in django
You can use mock:
import pytzfrom unittest import mockdef test_get_registration_date(self): mocked = datetime.datetime(2018, 4, 4, 0, 0, 0, tzinfo=pytz.utc) with mock.patch('django.utils.timezone.now', mock.Mock(return_value=mocked)): user = factories.UserFactory.create() self.assertEqual(user.get_registration_date(), mocked)
You can use the package freeze gun. https://github.com/spulec/freezegun which patchs datetime.now().
from freezegun import freeze_time... @freeze_time("2017-06-23 07:28:00") def test_get_registration_date(self): user = factories.UserFactory.create() self.assertEqual( datetime.strftime(user.get_registration_date(), "%Y-%m-%d %H:%M:%S") "2017-06-23 07:28:00" )
Just use the factory.post_generation decorator:
class UserFactory(factory.DjangoModelFactory): ... @factory.post_generation def registration_date(self, create, extracted, **kwargs): if extracted: self.registration_date = extracted
