RTest, a random testing framework

[BCS]

Reply to Fawzi,

I'm not quite following that, it seems to randomly select test values to 
supply to a function.
While I like that Idea, the implementation doesn't appeal to me (I have never 
liked string mixins if anything else is usable). I had an idea a while ago 
to might make for a better interface and might even allow better application 
of constraints:

double x,y;
Assert(1/x=pow(x,-1)).
    Where(x).NotZero.
    TestRandom();

Assert(x<y).
    Where(x).LessThan(y).
    Where(x).InRange(-10,10).
    TestEdges(1000); //< 1000 test points

Assert's arg would be lazy bool and the delegate would be storeed, the Where 
would use ref so it can pick up a pointer to x. Some sort of internal magic 
would keep track of what constraints apply to what and let the Test* functions 
inelegantly search the envelope.
