James,
Unit testing would be a good lightning talk. Here are some notes
from the session where I recently trained my team on it. You may
want to update some of the links. We're still on Django 1.4.
- Online docs:
- http://bristle.com/~fred/#django
- https://docs.djangoproject.com/en/1.4/topics/testing
- https://docs.djangoproject.com/en/1.4/topics/testing/#assertions
- Other links in my "Django" row
- http://bristle.com/~fred/#python
- https://docs.python.org/2/library/unittest.html
- https://docs.python.org/2/library/unittest.html#test-cases
- Other links in my "Python" row
% python manage.py help test
- Run all test methods in all test classes of all apps
% python manage.py test -v2
% python manage.py test -v2 appname...
- Run all test methods in all test classes of specified apps
% python manage.py test -v3 appname...
- Shows ALL steps. Too much detail for typical use
% python manage.py test -v2 appname.TestClass...
- Run all test methods in specified test classes
% python manage.py test -v2 appname.TestClass.test_name...
- Run specified test methods
- Ctrl-C to exit gracefully, Ctrl-C again to abort
- Create tests.py in each app
- Inherit from django.test.TestCase
- Or django.test.SimpleTestCase if no DB access needed
- Runs all tests (inherited from TestCase) in tests.py and models.py
- If you need to prevent South from running, use
SOUTH_TESTS_MIGRATE = False
- To avoid running tests of South itself, use SKIP_SOUTH_TESTS = True
- Creates/deletes "test_" DBs. Does not touch real DBs.
- Can detect in settings.py and elsewhere whether you're running tests,
and can then flip to SQLite for speed (30 seconds instead of 75
minutes):
RUNNING_UNIT_TESTS = 'test' in sys.argv
if RUNNING_UNIT_TESTS:
DATABASES['default'] = {
'ENGINE': 'django.db.backends.sqlite3',
'NAME': os.path.join(SITE_ROOT, 'default.sqlite'),
}
- Django suppresses all outgoing email during tests, and collects it
in a dictionary, so you can assert things about it
- Python Assertions and methods:
- assertEqual(a, b)
- assertNotEqual(a, b)
- assertTrue(x)
- assertFalse(x)
- assertIs(a, b)
- assertIsNot(a, b)
- assertIsNone(x)
- assertIsNotNone(x)
- assertIn(a, b)
- assertNotIn(a, b)
- assertIsInstance(a, b)
- assertNotIsInstance(a, b)
-
- assertRaises(exc, fun, *args, **kwds)
- assertRaisesRegexp(exc, r, fun, *args, **kwds)
-
- assertAlmostEqual(a, b)
- assertNotAlmostEqual(a, b)
- assertGreater(a, b)
- assertGreaterEqual(a, b)
- assertLess(a, b)
- assertLessEqual(a, b)
- assertRegexpMatches(s, r)
- assertNotRegexpMatches(s, r)
- assertItemsEqual(a, b)
- assertDictContainsSubset(a, b)
-
- skipIf()
- skipUnless()
-
- fail(msg=None)
- failureException
- longMessage
- maxDiff
-
- countTestCases()
- defaultTestResult()
- id()
- shortDescription()
- addCleanup(function, *args, **kwargs)
- doCleanups()
- Django Assertions and methods:
- SimpleTestCase.assertRaisesMessage()
- SimpleTestCase.assertFieldOutput()
- TestCase.assertContains()
- TestCase.assertNotContains()
- TestCase.assertFormError()
- TestCase.assertTemplateUsed()
- TestCase.assertTemplateNotUsed()
- TestCase.assertRedirects()
- TestCase.assertQuerysetEqual()
- TestCase.assertNumQueries()
- SimpleTestCase.assertHTMLEqual()
- SimpleTestCase.assertHTMLNotEqual()
-
- skipIfDbFeature('supports_transactions')
- skipUnlessDbFeature('supports_transactions')
- Advanced:
- setUp()/tearDown()
- setUpClass()/tearDownClass()
- setUpModule()/tearDownModule()
- suite()
- Can order your tests manually in a suite
- Can invoke a suite from another suite
- @unittest.skipIf/skipUnless()
- Mock HTTP requests
-
http://dougalmatthews.com/2010/Jan/20/testing-your-first-django-app/
- Tells:
- How to mock an HTTP request (easy!):
from django.test import Client
from mysite.polls.models import Poll, Choice
class PollTest(TestCase):
def test_voting(self):
c = Client()
# Perform a vote on the poll by mocking a POST
request.
response = c.post('/polls/1/vote/', {'choice': '1',})
# In the vote view we redirect the user, so check the
# response status code is 302.
self.assertEqual(response.status_code, 302)
# Get the choice and check there is now one vote.
choice = Choice.objects.get(pk=1)
self.assertEqual(choice.votes, 1)
- No. Per:
- https://docs.djangoproject.com/en/1.4/topics/testing
/#default-test-client
it is even easier. Just:
response = self.client.get('/customer/details/')
- How to mock an Ajax HTTP request:
def test_ajax_vote(self):
c = Client()
# Extra parameters to make this a Ajax style request.
kwargs = {'HTTP_X_REQUESTED_WITH':'XMLHttpRequest'}
# A valid vote
response = c.post('/polls/1/vote/', {'choice': '1',},
**kwargs)
self.assertEqual(response.status_code, 200)
self.assertEqual(response.content, '1')
# A invalid vote - choice doesn't exist
response = c.post('/polls/1/vote/', {'choice': '10',},
**kwargs)
self.assertEqual(response.status_code, 200)
self.assertEqual(response.content, '0')
# An invalid vote - poll doesn't exist
response = c.post('/polls/2/vote/', {'choice': '1',},
**kwargs)
self.assertEqual(response.status_code, 404)
- Selenium test cases with "LiveServerTestCase":
https://docs.djangoproject.com/en/1.4/topics/testing/#live-test-server
- Python Nose
- Django Nose
- Coverage
Hope this helps!

I want to attend a Django BarCamp in SF next weekend and BarCamp
tradition is that everyone contribute in some way.
Of course I will help out with set up/break down if that is needed,
but I would also like to give a lightening talk. I'm fairly unfamiliar
with Django at this point and I've never spoken publicly, so I am not
sure what I would talk about.
If anyone has any ideas that would be accessible for someone who is
relatively new to Django, I would love to hear them. It doesn't have
to be something I already know as I have a week to familiarize myself,
but given the short timeline it should be something accessible.
Happy hacking!
James
