Presentation given at Atlanta ALT.NET Meetup about Apress book Pro Agile .NET Development with Scrum. The book leads the reader through a hands-on project that features BDD with SpecFlow, TDD with mSpec, ASP.NET MVC for the web layer, a simple NHibernate based query service for reads, and a CQRS command bus for writes to the system DB. If you're in Atlanta, check out http://www.meetup.com/ATLAltDotNet. We will be continuing to work through the materials as a group over the last couple of months of 2011. Many thanks to Apress and the book's authors for letting our group use it and providing a half-off discount code for our group's members.

12. BDD Acceptance Tests: Outside-In
Behaviour-driven development is an “outside-
in” methodology. It starts at the outside by
identifying business outcomes, and then drills
down into the feature set that will achieve
those outcomes. Each feature is captured as
a “story”, which defines the scope of the
feature along with its acceptance criteria.
– Dan North, originator of term “BDD”
