Detailed Description

template<typename T>
struct is_testing< T, typename Void< typename T::testing >::type >

is_testing check if a struct T has testing member defined

Example

 
struct on_test
{
    typedef void testing;
};
 
struct not_on_test
{
};
 

 
    ret = is_testing<on_test>::value;
    BOOST_REQUIRE_EQUAL(ret,true);
 
    ret = is_testing<not_on_test>::value;
    BOOST_REQUIRE_EQUAL(ret,false);
 

return true if T::attributes::name[0] is a valid expression and produce a defined type
