django.core.exceptions.ImproperlyConfigured when trying to run tests with nose (not in django project)

Question

I've created a project to find out what project structure is right for my other python project.

What I really want to do is to run some tests.

example.py looks like this

import unittest
from A.A import A

__author__ = 'michael'


class ExampleTest(unittest.TestCase):
    def setUp(self):
        self.a = A()
        pass

    def test_stub(self):
        self.assertEquals(self.a.foo(), 'foo')

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

When I'm runnining

/Temp $ nosetests

I'm getting django exception.

Traceback (most recent call last):

    load_entry_point('nose==1.3.0', 'console_scripts', 'nosetests')()

    % (desc, ENVIRONMENT_VARIABLE))
django.core.exceptions.ImproperlyConfigured: Requested setting DATABASES, but settings are not configured. You must either define the environment variable DJANGO_SETTINGS_MODULE or call settings.configure() before accessing settings.

I don't get it at all. What have django has to do with it?

EDIT1:

Can't show you code, because I've already learned how to run tests with unittest and deleted this project.

But I assure you that the code for was A just about using B. Something like

class A(): def __init(self): self.b = B()

def foo(self): b.foo()

And B was just a class with a foo method that printed string 'foo'.

It's not a django project. What does this have to do with that? — user1685095, Jan 16 '14 at 07:56
Your code works perfectly fine, unless ``A()`` is using some Django component. Show us the code for ``A()``. — xbello, Jan 16 '14 at 09:43

From the line

File "/usr/local/lib/python2.7/dist-packages/queries/nose_plugin.py", line 22, in configure
    connection.use_debug_cursor = True

It seems that you have installed django-dynamic-fixture. This package installs a nose_plugin that uses django ORM.

Disable django-dynamic-fixture (I don't know how to do it) OR
Uninstall django-dynamic-fixture OR
Work in isolated virtualenvs.
