Unit Testing – the Hard Parts @ NYC Code Camp

Thanks to everyone who came to my “Unit Testing – the Hard Parts” presentation @ New York Code Camp. I really enjoyed it! Great crowd, lots of follow up questions. And cool Microsoft office space in Times Square. Thank you to all who attended. My slides are here: http://www.slideshare.net/shaunabram/unit-testing-the-hard-parts
