If you have a GUI Toolkit, and if it stores objects in
memory before painting them (like most do) then those
test tools will solve a problem that you don't have.

Faucet. 

When you write a debugging trace statement, like this:

  sprintf("x is %i today\n", x);

that's like turning on a little hose; the value of X
streams out of it. Programmers turn these traces off
like this:

 //  sprintf("x is %i today\n", x);

When you use David's reveal() method, you do the same
thing with the entire window.

However, this is not strictly a testing technique;
it's a way to re-verify the tests. The more you use
reveal(), the better your tests get, and the less you
need to use it.

In general, write tests like this:

int main(int argc, char** argv)
{
      QApplication qApp(argc, argv);
      
      //create an empty dialog object
      QDialog* dialog = new QDialog();
      
  assert(dialog->getTitle() == "dammak's dialog");

      // hide the dialog
      //reveal(dialog);      
      
      int dummy; std::cin >> dummy; // pause
      
      return EXIT_SUCCESS;
}

Treat the GUI objects as just another library - not
anything special. This requires you to learn how to
write code substantially differently from the Qt
tutorial code...

But of course use a test rig like CppUnit - not main()!
