[Django]-Running django tutorial tests fail – No module named polls.tests

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
│   ├── templates

Anyhow running 

$ python manage.py test polls.tests

It works, it’s enough for me right now:

Creating test database for alias 'default'...
