Installed app in Django not found when running tests

I have a pretty simple Django app, that I am trying to run unit tests on. In my tests.py file I am trying to import the parent apps views file. I tried 'from . import views' but got an error:

SystemError: Parent module '' not loaded, cannot perform relative import


I read that when a relative path does not work, you can try using an absolute path so I tried 'from menu import views' but than got another error:

ImportError: No module named 'menu'


When I run a local server for the application it works just fine. Its only when I run 'coverage run 'coverage run menu/tests.py'. Since it is running fine, and the module is in my setting's installed apps, Im not entirely sure why this is happening.

menu/tests.py

import unittest

from menu import views

class ModelTestCase(unittest.TestCase):
def setUp(self):
pass

def test_menu(self):
pass

if __name__ == '__main__':
unittest.main()


settings.py

INSTALLED_APPS = (
'django.contrib.admin',
'django.contrib.auth',
'django.contrib.contenttypes',
'django.contrib.sessions',
'django.contrib.messages',
'django.contrib.staticfiles',
'menu',
'django_nose'
)


Traceback

timothybaney$ coverage run menu/tests.py
Traceback (most recent call last):

Answer

It's not much information you gave us.. but when I take a look at the Traceback it says File 'menu/tests.py'. So if the views.py is also inside the menu Folder you just can write:

import views

If the views.py is in the main folder you could write:

from ..main import views   #replace 'main' with your folder name
