Hi All

This is sort of off-topic but I figured if anybody has ever tried this 
they must be on the MbUnit group :-) In short my problem is that I need 
a verification and validation tool (if those terms mean anything). In 
essence I need a way to track the accuracy of class implementations. I'm 
mainly interested in numerical stuff so the answer can be slightly 
different each time, making normal unit tests complicated. Giving a wide 
difference margin is not really acceptable, and in some cases it's not 
really possible, for instance there are cases where you want a number to 
be as close to zero as possible, but you don't really know how close it 
will be. I'd also like to compare the results of the calculations with 
existing results and be able to store the new results / differences. 
That way you could track accuracy over time.

I'd also like to track the performance of the different implementations 
so that a developer can see if their changes help performance or not. 
Again it would be helpful to be able to store the timing results per 
test per run.

Now I know I could code this all up inside an MbUnit test but there's a 
lot of repetitive code necessary for these tests (file / database 
reading/writing, comparisons, timers etc.). Also I'm not sure how to get 
all the statistics of a unit test from inside the unit test (timing, the 
name of the test, when it's run etc.)

I have thought about writing my own verification framework but before I 
give into the Not-Invented-Here syndrome I'd figure I do some searching 
to see if anybody else has ever done something like this.

So my question to you, has anybody ever seen something like this? Or 
done something like this? Any hints and tips?

Thanks heaps

Patrick
