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

Question

I have my tests for a Django application in a tests directory:

my_project/apps/my_app/
├── __init__.py
├── tests
│   ├── __init__.py
│   ├── field_tests.py
│   └

If you use django-nose you can use a simple selector:

from nose.selector import Selector
from nose.plugins import Plugin
import os
import django.test

class TestDiscoverySelector(Selector):
    def wantDirectory(self, dirname):
        parts = dirname.split(os.path.sep)
        return 'my_app' in parts

    def wantClass(self, cls):
        return issubclass(cls, django.test.TestCase)

    def wantFile(self, filename):
        parts = filename.split(os.path.sep)
        return 'test' in parts and filename.endswith('.py')

    def wantModule(self, module):
        parts = module.__name__.split('.')
        return 'test' in parts

class TestDiscoveryPlugin(Plugin):
    enabled = True

    def configure(self, options, conf):
        pass

    def prepareTestLoader(self, loader):
        loader.selector = TestDiscoverySelector(loader.config)

This is just an example implementation and you can make it more configurable or adjust it to your needs. To use it in your Django project just provide the following option in settigs.py

NOSE_PLUGINS = ['lorepo.utility.noseplugins.TestDiscoveryPlugin']
