Tested that get_or_create raises IntegrityError.

class ManualPrimaryKeyTest(models.Model):

    id = models.IntegerField(primary_key=True)

    data = models.CharField(max_length=100)

class Profile(models.Model):

    person = models.ForeignKey(Person, primary_key=True)

class GetOrCreateTests(TestCase):

            formatted_traceback = traceback.format_exc()

            self.assertIn('obj.save', formatted_traceback)

class GetOrCreateTransactionTests(TransactionTestCase):

    def test_get_or_create_integrityerror(self):

        # Regression test for #15117. Requires a TransactionTestCase on

        # databases that delay integrity checks until the end of transactions,

        # otherwise the exception is never raised.

        try:

            Profile.objects.get_or_create(person=Person(id=1))

        except IntegrityError:

            pass

        else:

            self.skipTest("This backend does not support integrity checks.")
