Here is the Boost Test assertion:

BOOST_CHECK_EXCEPTION(dummyOpr->setOperand(emptyValue), DiGSE::fail, 
fail_msg);

Here is the test execution log message:

info: check 'incorrect exception DiGSE::fail is caught' has passed

I have only one exception: *DiGSE::fail* (derived from 
*std::exception*). It is the /only /exception that appears in the 
*BOOST_CHECK_EXCEPTION()* assertions.  So, what does "incorrect 
exception *DiGSE::fail*" mean?  If *DiGSE::fail* was caught, then that 
part is correct.  If the message means that some /other/ exception was 
caught, then this is a Really Poor way of phrasing that information.

Or, did the predicate return *false* (which, in my case, means the 
exception message is wrong)?

But if the wrong exception was caught /or/ the predicate returned 
*false*, then why was the assertion declared "has passed"?
