compiling a different exe for testing that behaves differently sounds bad to me.
What we do often is write code like;

#ifndef NDEBUG
    do some extra stuff here to test everything is going Ok.
#endif

This code should not change the behavior of the app, other than maybe 
asserting.   The reason for that is that its really hard to maintain an 
application that behaves differently in different compilation modes.
This is why we use QTextLib based unit tests; kevin pointed out great links to 
those already.
