Hi, Is there a way to get the funcationality of BOOST_CHECK_EQUAL when I want to test that two parameters are not equal to each other? I like the way BOOST_CHECK_EQUAL allow me to see the mismatched runtime values. I have been creating a custom message for BOOST_CHECK_MESSAGE to achieve this functionality, but it would be nicer if there was an automated way to do it. Thanks, Ed Johnson

great, Thank you! and for completeness, there needs to be an additional () in order to compile: BOOST_CHECK_PREDICATE( std::not_equal_to<T>(), (a)(b) ); BOOST_CHECK_PREDICATE( std::not_equal_to<int>(), (3)(3) );
What would you propose for floating-point comparisons? On 6/2/06, Gennadiy Rozental <gennadiy.rozental@thomson.com> wrote:

What would you propose for floating-point comparisons?
BOOST_CHECK_CLOSE - checks that two FP values relative difference doesn't exceed specified percent. BOOST_CHECK_CLOSE_FRACTION - checks that two FP values relative difference doesn't exceed specified value BOOST_CHECK_SMALL - checks that module of particular value doesn't exceed tolerance value Gennadiy
Right. I meant what would you propose for checking inequality for floating-point types? Similar to the original poster asking for BOOST_CHECK_NOT_EQUAL(), what I'm asking about is a BOOST_CHECK_NOT_CLOSE() or BOOST_CHECK_NOT_SMALL() which would use the appropriate tolerance algorithm. Is there a way of getting this kind of result with the current tools? On 6/8/06, Gennadiy Rozental <gennadiy.rozental@thomson.com> wrote:

using namespace std; using namespace boost::test_tools; BOOST_CHECK_PREDICATE( not( check_is_close ), (a)(b)(percent_tolerance(t)) ); BOOST_CHECK_PREDICATE( not( check_is_close ), (a)(b)(fraction_tolerance(t)) ); BOOST_CHECK_PREDICATE( not( check_is_small ), (a)(t) ); Gennadiy

I thought we agreed that you would make all these available as easy-to use macros? Also for version taking a Range. -Thorsten

I didn't have record of this, but I am ready to reconsider this after release. My personal opinion is that above is not that wordy to warant huge number of extra tools for all possible simple predicates. On the other hand <functional> have predicate for each one. I would like to hear users input on this one.

The same here. Gennadiy

Could you please bring this issue up again on main list once 1.34 is shipped or you prefer me to do this? Gennadiy
