Nose doesn't find Django tests

Question

I am trying to use Django-nose in my current project, but I can't figure out how to get nose to run my tests. So I started a simple Django 1.4.1 project to get to know nose. But not even on this simple test project I could get it running.

Before I go on: I know there are a ton of similar questions on Stackoverflow, like for instance this one:

How do I tell Django-nose where my tests are?

But after Googling around, reading blog posts and StackOverflow answers I still couldn't get it running.

How I set up my test project

1. Create virtual environment.
2. pip install django django-nose nose.
3. Create project with django-admin.py startproject djangonosetest.
4. Create an app manage.py startapp testapp

5. Edit settings.py:

   • Set ENGINE to django.db.backends.sqlite3
   • Added django_nose, testapp to INSTALLED_APPS
   • Added TEST_RUNNER = 'django_nose.NoseTestSuiteRunner'.

6. Run manage.py test

But all I got was this output:

nosetests --verbosity 1
Creating test database for alias 'default'...

----------------------------------------------------------------------
Ran 0 tests in 0.000s

OK
Destroying test database for alias 'default'...

But at least the default test case should have been run.

When I run python manage.py test djangonosetest.testapp.tests:SimpleTest it'll run the test. But that seems a bit overkill if I had to do it for every test file I have. But it proves that the tests can be run.

When I ran manage.py test -v 3 (high verbosity level) this showed up:

nose.selector: INFO: /Users/Jens/Projects/Django/djangonosetest/djangonosetest/settings.py is executable; skipped
nose.selector: INFO: /Users/Jens/Projects/Django/djangonosetest/djangonosetest/settings.pyc is executable; skipped

nose.selector: INFO: /Users/Jens/Projects/Django/djangonosetest/manage.py is executable; skipped

The nose does definitely find my tests.py but is skipping it for some reason.

The test code

The test code is the default TestCase Django creates.

"""
This file demonstrates writing tests using the unit test module. These will pass
when you run "manage.py test".

Replace this with more appropriate tests for your application.
"""

from Django.test import TestCase


class SimpleTest(TestCase):
    def test_basic_addition(self):
        """
        Tests that 1 + 1 always equals 2.
        """
        self.assertEqual(1 + 1, 2)

So how do I tell Django-nose/nose where my tests are?

UPDATE

If found an interesting Google Groups post and Stackoverflow answer on the subject:

• Google Groups Post
• Stackoverflow answer

Both boil down to the fact that nose will skip executable files. That's why I get tests.py is executable; skipped. Problem is that the file is not executable:

----------+ 1 Jens  staff  383 13 Okt 00:01 tests.py

I also tried it with u-x, g-x and o-x but nose skipped anyway. I get the feeling that this is a bug. The file is found in the nose, is not executable but still skipped.

A workaround is to use the --exe switch. Running manage.py test --exe runs the test. While it's better than the other workarounds I am not completely happy with that solution.

your setup looks fine... just to check stupid little mistakes that we all make... did you spell testapp right in settings? Or something else like that? – Coact

Is this a myapp/tests.py vs. myapp/tests/__init__.py issue? I don't know much about Nose, or what it changes about the way Django runs tests, but Django finds tests inside files called tests.py, not inside modules called tests. – Ophidian

@Coact I checked the spelling. It's alright. – Holmgren

@Ophidian nose.readthedocs.org/en/latest/finding_tests.html Nose looks for pretty much anything matching *test* it sounds like... Jens's setup seems easily findable by Nose. – Coact

@Ophidian I followed the django-nose documentation github.com/jbalogh/django-nose and it says nothing about changing any tests. So I assume you just can run manage.py test and everything works. – Holmgren

@Coact right you are, I've just installed nose and successfully run my test. Jens, could you post your test code? – Ophidian

Answer 1

I had the same issue today and I fixed it.

Try:

chmod a-x djangonosetest/djangonosetest/testapp/*.py

Somebody answered here too: #6333995 – Denysedenzil

You saved my day. Nose is crappy. – Blocker

Answer 2

I think it might be that in Django 1.4 you need to specify the project in installed apps if you don't specify a project root. Instead of just 'testapp', try 'djangonosetest.testapp'

https://docs.djangoproject.com/en/dev/ref/settings/#std:setting-INSTALLED_APPS see their example.

Coact

I already thought of that as a potential error source. So I moved testapp from the root directory (where manage.py is) to the project folder (djangonosetest) and updated INSTALLED_APPS. Did not help. – Holmgren

maybe post your current directory structure and your settings file? – Coact
