Look, No Mocks! Functional TDD with F# - talk by Mark Seaman

I came across this cool video from Mark Seemann, one of my heros - here. I really need to get into F# if I listen to this guy...

The reason I know him is from this video on PluralSight: http://www.pluralsight.com/courses/functional-architecture-fsharp which I very much enjoyed.
