Re: [boost] Is there interest in unit testing both passing and failing BOOST_MPL_ASSERTs?

Hi Dave,

If you're just checking MPL assertions, then presumably there's a predicate that can be evaluated without throwing. Why not just feed those predicates' results to regular runtime assertions?

In addition to feeding those predicates to runtime assertions a type pretty-printing utility can be used to provide more detail on why the predicate failed. Relying on a pretty-printer rather than the compiler error messages makes the output standard across platforms/compilers and more readable in many cases.

Okay, point taken. But that's *not* BOOST_MPL_ASSERT. IMO you need a different macro for that purpose. -- Dave Abrahams BoostPro Computing http://www.boostpro.com
