I spoke in Mumbai recently about an open-source framework created to assist in End-2-End automated Integration Testing using TaaS - Test as a Service. The slides for the talk are available here and audio here.
The session was planned for 1 hour. I managed to finish the talk in 50ish minutes, then then the Q&A went on for another 30ish minutes.
Plan is to create and publish TaaS as a gem on rubygems.org.
Looking forward to your comments / feedback for the same!!
