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

But I need a way to write a run-time unit test which will demonstrate that this code will fail to compile, when instantiated by the user of the library.

Then your run-time unit test needs to invoke the compiler, right?

When instantiated by the unit-test framework, the code instead throws an exception.

How does "the code" throw an exception if it doesn't even compile? At best you're showing that some other, similar-looking, code will throw an exception. What does that really mean though? Especially for the types of things MPL is used for. - Marsh
