Override settings.py for testing
I suppose the easiest way would be to move your settings.py to another folder for safekeeping and then make a new one, and edit that for debugging.
I have my project settings in settings.py file. There are database names, user names, host names etc. defined there. In project files I do import settings and then use the constants where needed like settings.HOST. For unit testing I would like to use different settings. How should I override the settings? I am not using django.
