Re: Testability and normative requirements

This goes back to the argument about whether all requirements should be testable.  I believe that If you can't figure out a way to test a requirement, it should not be included in the specification. Others disagree. 

If  you buy into my argument, there is a contradiction. Otherwise there is not. In any case, a cost analysis of non testable requirements would be very difficult, if not impossible.

Subject: Testability and normative requirements


Hello QA IG,

Is there a logical contradiction behind the idea of a normative
requirement that would not be testable? I don't think there is, but
would be interested to hear what others think about it.

More generally, if the IG could produce some kind of finding on the
relationships between testability and "normativity" (e.g. with the costs
of having non-testable normative requirements), I would find it very
useful. The Wiki could probably host it...

Thanks,

Dom
