As I modify the starter site with new App_Code classes it would be very valuable to extend the Unit Tests to cover the new classes. In trying to do this I immediately ran into problems concerning the HttpContext and SiteContext and setting properties in these objects to the the state I needed for my tests. What recommendations do people have for writing unit tests which reference these context objects. I see that the Starter Site Unit Tests don't reference them and don't include tests for classes or methods which rely on these context objects.
