A TraceListener For Tests
In my code, I make extensive use of debug assertions (see System.Diagnostics.Debug.Assert). These assertions are very helpful while debugging because you don’t need to step into every line of code to see if all pre-conditions are met. As soon as a pre-condition fails, an assertion failed window will pop up and will allow us to either abort, ignore or go to the assertion instruction (retry).
