Boost :: test exception message

Question

Using a structure boost::test, is there a way to determine if an exception (of some type) was excluded from a function?

Answer 1

Do you want to check if the function is selected correctly in some circumstances? If so

BOOST_CHECK_THROW( function(), exception_type );

will do it. you can use

BOOST_CHECK_EXCEPTION( function(), exception_type, predicate )

to call an arbitrary predicate to exclude when it is caught, and

BOOST_CHECK_NO_THROW( function() )

so that the function does not throw.
