Created April 12, 2013 09:54

Django test suite discovery that works with `python manage.py test` and `django-jenkins`. If you want to put your tests in a folder instead of `tests.py`, you need to define a `suite` in your `models.py` as below.

	# put this in your_app/models.py
	def suite():
	"""Django test discovery."""
	import nose
	import unittest
	path = os.path.join(os.path.dirname(__file__), 'tests')
	suite = unittest.TestSuite()
	suite.addTests(nose.loader.TestLoader().loadTestsFromDir(path))
	return suite
