project
-----------------------------------+----------------------
Reporter: prinsherbert | Owner: nobody
Type: Bug | Status: new
Component: Testing framework | Version: 1.9
Severity: Normal | Keywords: database
Triage Stage: Unreviewed | Has patch: 0

-----------------------------------+----------------------
Create django project and application and remove some superfluous files:
{{{
django-admin startproject foo
cd foo/
django-admin startapp bar
rm -rf bar/migrations/ bar/models.py bar/apps.py bar/admin.py foo/wsgi.py
}}}
Changed the files to look like this:
{{{
# foo/settings.py
import os
BASE_DIR = os.path.dirname(os.path.dirname(os.path.abspath(__file__)))
SECRET_KEY = '1234'
DEBUG = True
ALLOWED_HOSTS = []
INSTALLED_APPS = [ 'bar' ]
MIDDLEWARE_CLASSES = []
ROOT_URLCONF = 'foo.urls'
DATABASES = {}
}}}
{{{
# foo/urls.py
from django.conf.urls import url
from bar.views import my_oh_my
urlpatterns = [
url(r'^$', my_oh_my),
]
}}}
{{{
# bar/tests.py
from django.test import TestCase
class TestFoo(TestCase):
def test_foo(self):
assert True
print('tested!')
}}}
{{{
# bar/views.py
from django.shortcuts import render
from django.http.response import HttpResponse
def my_oh_my(request):
return HttpResponse('my, oh, my!')
}}}
Both foo and bar have an empty {{{__init__.py}}}. Running this project as
a server is fine, however testing it results in this error:
{{{
# python3 manage.py test
tested!
.E

ERROR: test_foo (bar.tests.TestFoo)

It states that I need to better configure the DATABASES variable, which I
think is not adequate.
