RE: [boost] Boost Test tools to test manipulators likehex,setw(15)...

Thanks but because what I want to pass is effectively a PROGRAM string

"<< hex << showpoint << showbase << MySpecialManips  ..."

AND I need a special ostream initialiser "setDefaults(oss)"

#define CHECK(manips, result)\
{\
        ostringstream oss;\
        setDefaults(oss);\
        oss << manips;\
        BOOST_CHECK_EQUAL(oss.str(), result);\
}

conlcude I must use a macro  :-(  Nasty but effective.

But your to_string looks most useful generally.  Perhaps if I convert the
setDefaults to a manipulator and write

 oss << setdefaults << manips

Does this look feasible with your to_string?

to write

BOOST_CHECK_EQUAL(setDefaults << hex << showpoint << showbase <<
MySpecialManips, "expected string");

Thanks.

| I might have understood this all wrong, but maybe this will help you:

| You can write what you wish, and as many manipulators as you wish.
| And at the end, it's automatically converted to string.
