Nikolai Tillmann answered the same question on the Pex forums: http://social.msdn.microsoft.com/Forums/en-US/pex/thread/71c90936-b3af-4d90-af87-f6ecba797cb7

There are quite a few Channel 9 videos that explain how Pex works but I'd take a look at this one first. A lot of the episodes of The Verification Corner also go over the concepts even if they don't say so explicitly.
