Why does Django say that I have not set DATABASE_ENGINE yet?

Question

I have a Django project and I'm a little new to it. I have the following PyUnit test trying to save an object in a PostgreSQL database:

import unittest

from foo.models import ObjectType

class DbTest(unittest.TestCase):
    def testDBConnection(self):
        object_type = ObjectType()

        object_type.name = 'Test Object'
        object_type.description = 'For testing purposes'

        object_type.save()

And my database settings are as follows:

DATABASE_ENGINE = 'postgresql_psycopg2'           
DATABASE_NAME = 'FOO'             
DATABASE_USER = 'username'            
DATABASE_PASSWORD = 'password'         
DATABASE_HOST = 'localhost'            
DATABASE_PORT = '5432'    

I ran python manage.py syncdb for my project that worked successfully, so my database needs to be configured correctly. However, when trying to run the unit test above:

I get the following error:

File "C: \ Python26 \ Lib \ site-packages \ Django \ DB \ engines \ dummy \ base.py", line 15, in the complaint Raise Incorrectly configured: "You have not set DATABASE_ENGINE yet." Incorrect Configured: You have not set the DATABASE_ENGINE installation yet.
