TDD, Architecture and Testing Code in Isolation :: Part 2

In the next part of this series I undertook are some of my various clean ups. Create respective test classes for each of the pieces of the database that will have respective entities, methods, or objects to test. But before really getting on a roll with the tests I have to detour through creating a fake for the DataContext Object for my LINQ to SQL Data Access Layer. So check it out, and send some feedback.
