Comment (by Architekt):
Yesterday I tried `DATABASES = {}` as author of this ticket did. This
configuration is not loading dummy backend and everything raises
ImproperlyConfigured. Even `manage.py shell` is not working. I checked
comment in dummy backend base.py which says "Right now the dummy backend
is there for raising ImproperlyConfigured if database configuration is
missing." so I thinked that all those raises are correct and Django can't
run without database settings.
But with setting database engine as `django.db.backends.dummy` or removing
whole databases configuration from settings is a different story. Shell
works fine. Tests fail on creating database:
{{{
$ ./manage.py test myapp -v 2
Creating test database for alias 'default' ('test_')...
ImproperlyConfigured: settings.DATABASES is improperly configured. Please
supply the ENGINE value. Check settings documentation for more details.
}}}
I see here two problems:
1. In docs is default DATABASES setting empty dict. But when you set
`DATABASES = {}` in project settings (which doesn't use dummy backend) it
doesn't work like real default without any DATABASES in project settings
(which uses dummy backend).
2. Test runner does not know how to handle dummy database.
