MsTest - Not Executed – Time to go to normal xUnit

For last couple of days I was trying to figure out why I’m getting “Not Executed” result for all my tests in a project.
The solution (Is it that Peter Morris who posted it?) is to Unblock an assembly (in my case it was Microsoft.Web.Mvc.dll).
This issue, probably,  is a typical example when exceptions are handled and eaten.
I’m not sure i want something similar to occur again and will probably move to more common unit testing framework like nUnit, MbUnit or xUnit later.
