You deserve the World's Best Intro to Test-Driven Development, and here it is.
This demonstration video chronicles delivering the first feature of a point of sale terminal using real-life technologies include Heroku and a UPC (price code) barcode reader. Unfortunately, I couldn't figure out how to connect the application to a portable LCD, so I had to settle on the browser as my display.
In this one-hour-long video I deliver a single feature from end to end using Presenter-First Design with Mock Objects in Java. (No integrated tests here!) If you'd like to download this video, you can do so directly from Vimeo.
