This is doable. The message would sould like this:
difference between var1 {<value>} and var2 {<value>} is x% and exceeds e%
Good. This one is quite pressing for me, as there are some failing tests I can't diagnose otherwise :-/
I am working on Boost.Test update these days. I hope it to be soon.
Has to be a new tool, too much would break otherwise, I like the name BOOST_CHECK_CLOSE_EPSILON suggested elsewhere.
Ok. So be it. Actually An ideal solution would be somethind like: BOOST_CHECK_CLOSE( a, b , 0.5% ) - test in percents BOOST_CHECK_CLOSE( a, b , 0.05) - test in epsilon But I couldn't figure out how implement it
This one already exists: BOOST_CHECK_SMALL( v, epsilon )
Sorry that's not what I meant, I meant when BOOST_CHECK_CLOSE or BOOST_CHECK_CLOSE_EPSILON fail then they should print out:
The two input values. The max relative error permitted. The actual relative error found. The actual absolute error found.
More information is a good thing in this case :-)
Absolute difference would clutter output. Especially since it could be completely unrelated. I am not sure we want this always. Gennadiy
