I am trying to run a simple Django test in PyCharm, but its failing with the following stack trace-

```
/home/ramashishb/local/pyenv/testenv/bin/python /opt/pycharm-3.0.2/helpers/pycharm/django_test_manage.py test snippets.SimpleTest.test_simple /home/ramashishb/mine/learn/django-rest/django-rest-tutorial
Testing started at 4:37 PM ...
Traceback (most recent call last):

django.core.exceptions.ImproperlyConfigured: Requested setting CACHES, but settings are not configured. You must either define the environment variable DJANGO_SETTINGS_MODULE or call settings.configure() before accessing settings.

Process finished with exit code 1

```

The test runs fine on console using- `./manage.py run test`
It looks like things are not setup before executing the tests?

Any idea?

Thanks,
Ram
