MFC has major architectural flaws that resist clean testing. One good policy
is to use "in vivo" testing, per the book /Working Effictively with Legacy
Code/ by Mike Feathers. That means you start the application's main work
loop, and after the main window has painted you encounter a line of code
like this:

#ifdef DEBUG
runTests(mainHwnd);
#end

That means when you run your program from VC++, in Debug mode it will invoke
a test rig, and pass in a handle to the main window. The tests now operate
on the window, treating all its subwindows and controls as objects.

I would use UnitTest++ for the test rig. It's designed to be lean and
non-invasive (unlike MFC), so you'll easily squeeze it into the runTests()
function.

Ask about any more questions!
