Slides from presentations Graham Taylor and I gave on Drupal, BDD and Behat at Drupalcamp London, March 2013 and Front End United, April 2013.
A couple of people wrote some very kind words about it. You can download the code from Graham's github repo which uses the Drupal 7 Commerce Kickstart profile (http://drupal.org/project/commerce_kickstart), with Behat/Mink testing using Travis CI (https://travis-ci.org) and Saucelabs (https://saucelabs.com)
