Then the question arizes How did you test that your implementation is correct or at least does work at all?
I and my clients uses it realization in 1C Accounting application for years. I do not see better test now. In other words, It works for me.
The question is how have you developed an implementation in the first place? How do you know what should it do internally and which corner/error cases should you handle and how? The only answer to that questions could be done by test cases written specifically for cases you want to test, or not clear from MSDN, or to prove that your implementation is correct at all.
