Running django tutorial tests fail – No module named polls.tests
Question:
I’m playing with django 1.6 tutorial but i can’t run tests.
My project (name mydjango) and app structure (name is polls) are as shown below in a virtualenv. (.nja files are just created by ninja-ide the ide I’m using)

I followed the tutorial to understand how django works but I’m stuck in the test part.
As tutorial suggest I created a file named tests.py into the app folder, the pretty straightforward file is:
# -*- coding: utf-8 -*-
from django.test import TestCase
import datetime
from django.utils import timezone
from polls.models import Question
# Create your tests here.l
class QuestionMethodTests(TestCase):
def test_was_published_recently_with_future_poll(self):
"""
was_published_recently dovrebbe ritornare falso se si mette una data nel futuro
"""
future_question = Question(pub_date=timezone.now() + datetime.timedelta(hours=50))
self.assertEqual(future_question.was_published_recently(), False)
then i installed unittest2 into the virtualenv with
$pip install unittest2
and run
$python manage.py test polls
Creating test database for alias 'default'...
E

No way to have the test working, also if don’t pass the app name it returns the same error:
$ python manage.py test
Creating test database for alias 'default'...
E

My INSTALLED_APPS are:

'django.contrib.messages',
'django.contrib.staticfiles',
'polls',
)
What am I doing wrong?
Answers:
Anyhow running
$ python manage.py test polls.tests
It works, it’s enough for me right now:

first answer didn’t work for me. im using win8, may be this is a reason.
in terminal try to change dir to ./polls and the run
python ../manage.py test polls
I had exactly the same issue with my Django project:
$ python manage test polls.tests
worked fine whereas the following failed with an import error:
$ python manage test polls
$ python manage test
(...)
ImportError: Failed to import test module: mydjango.polls.tests
Traceback (most recent call last):
(...)
ImportError: No module named polls.tests
Check carefully the error message: Django’s test runner tries to import the tests from mydjango.polls.tests where mydjango is the name of the root directory (the container for your project).
I fixed this issue by deleting the __init__.py file in mydjango directory (at the same level than manage.py file). This directory is not supposed to be a python module and it seems to mess up with Django’s test runner if it is the case.
So just deleting the _init_.py file should fix our problem:
$ rm mydjango/__init__.py
For anyone else having the same problem, another reason for this to happen is if you have the same name for the root folder and the project folder.
For example:
mydjango
├── __init__.py
├── manage.py
├── mydjango
│ ├── __init__.py
│ ├── settings.py
│ ├── urls.py
│ ├── wsgi.py
├── polls
│ ├── admin.py
│ ├── __init__.py
│ ├── models.py
| ├── tests.py
│ ├── templates
running
./manage.py test
throws errors No module named polls.tests
to fix it simply rename the root folder to something else like :
mydjango_project
├── __init__.py
├── manage.py
├── mydjango
│ ├── __init__.py
│ ├── settings.py
│ ├── urls.py
│ ├── wsgi.py
├── polls
│ ├── admin.py
│ ├── __init__.py
│ ├── models.py
| ├── tests.py
