environment variable for django settings?

I've been using Django for over a year and have never needed to 'define the environment variable DJANGO_SETTINGS_MODULE as I am asked to do in the following error message:

E
======================================================================
ERROR: setUpClass (__main__.SmokeTest)
----------------------------------------------------------------------
Traceback (most recent call last):

    for conn in connections.all())

    self._databases = settings.DATABASES
  File "C:\Python27\lib\site-packages\django\conf\__init__.py", line 55, in __getattr__
    self._setup(name)
  File "C:\Python27\lib\site-packages\django\conf\__init__.py", line 41, in _setup
    % (desc, ENVIRONMENT_VARIABLE))
ImproperlyConfigured: Requested setting DATABASES, but settings are not configured. You must either define the environment variable DJANGO_SETTINGS_MODULE or call settings.configure() before accessing settings.

I am using Windows command line.

I tried running 

from django.conf import settings

settings.configure()

as explained here, but this didn't help.

Does anyone know how to get this to work?

"@brunodesthuilliers in the command line I am in my app directory, I run python tests.py "

Well that's not going to work (at least not that easily). Why don't you just use the builtin management "test" command ?

 #> cd your/project/root 
 #> python manage.py test

Are you sure in your manage.py have something like this

os.environ.setdefault("DJANGO_SETTINGS_MODULE", "projectname.settings")
