I spoke at a recent New York Python Meetup Group event hosted by Stack Overflow that focused on a library we open-sourced called dsert. At Paxos, we use it for API testing, and you might want to as well. Using dsert we can test all the fields of a python dictionary, even when we don't know all of their values. This ensures that tests are as explicit as possible. You can watch the full video below, or on our Paxos YouTube page.
