For tests that use the database, you need to extend from
django.test.TestCase, not unittest.TestCase. Django's custom TestCase will
ensure that the database is reset to its initial state between tests (see
https://docs.djangoproject.com/en/1.3/topics/testing/#testcase). The need
for using Django's custom TestCase is unfortunately not currently properly
noted in the docs, and there is a ticket open on that (
https://code.djangoproject.com/ticket/17312).

Django testing and unique=True

[Acruax]

Hi,
I have a problem with model testing. My test fails with error:
  IntegrityError: duplicate key value violates unique constraint
"catalog_name_key"
  DETAIL: Key (name)=(test_catalog1) already exists.

I have unique=True on name field.

class CatalogTestCase(unittest.TestCase):
def setUp(self):
self.catalog1 = Catalog.objects.create(name="test_catalog1",
title_ru="Test Catalog1")
