Adding tests

[chrisclark]

Here's a test that will verify that the url functions have indeed been decorated:

from django.test import TestCase
from django.conf.urls import url, include
from functools import wraps
from core.url_utils import decorated_url


def spy_decorator(func):
    @wraps(func)
    def wrap(self, *args, **kwargs):
        return func(*args, **kwargs)
    wrap.__spy__ = "spied"
    return wrap


class TestDecoratedUrl(TestCase):

    def test_urls_get_decorated(self):
        urls = [
            url(r'^$', lambda r: "Huzzah!", name='test_url_resolver'),
        ]
        res = decorated_url(r'^foo/', include(urls), wrap=[spy_decorator])
        self.assertEqual(res.resolve('foo/').func.__spy__, 'spied')
        self.assertTrue(res)
