Django can't find settings file when running unit tests
django, django-testing, pycharm
Solution
Are you using Djangos unit test library, or are you using pythons? Django needs some things to be setup in order to be able to load e.g. models, i.e. it needs settings as your stack trace suggests.
If you follow the documentation https://docs.djangoproject.com/en/1.5/topics/testing/overview/ you can see that Django has done some addons to the normal unit test functionality. Using that and invoking the tests as Django unit tests will run it for you. Running it as Django unit tests means running them with
`$ ./manage.py test`
or since your using pycharm, you can select to run the unit test as a Django unit test, PyCharm should ask you when you invoke the test.
Problem
I'm trying to run unit tests on my django application but I'm getting following error. Running application is fine though. I'm using pycharm 3.0. ``` C:\Users\user\my-project-env\Scripts\python.exe "K:\Program Files (x86)\JetBrains\PyCharm 3.0\helpers\pycharm\utrunner.py" C:/Users/user/PycharmProjects/my-project/my_app/ true Testing started at 20:16 ...
