I had the great privilege to present this weekend at PyCon Australia 2013. My talk was originally titled "Why I Use py.test and Maybe You Should Too" but as I wrote the paper and accompanying slides I realised that it should really have been called "How to Start Unit Testing" as that was really the key message from my talk.
I've uploaded the slides and the paper I wrote to accompany them to the presentations section of this site. Feedback and corrections are alway welcome. Thanks to the PyCon Australia committee, volunteers and delegates for another great conference.
