Dear monks,

One of the big problems of GUI programming is testing. It's simple to develope extensive test-suites for data munging applications, but once it comes to a GUI, we're stuck.

I have a complex GUI application for data display - it reads data from files and displays it on the screen. I want the feeling of confidence a test-suite provides for this program as well, but I just can't think of a good way to write unit tests for it. Sure, I have test suites for the non-GUI components, but sometimes, as it is in my case, the GUI itself is the bulk of the functionality.

The less frigthening way I've heard of is creating special "dump" functions for testing purposes only which dump what's on the screen to files, allowing to diff/test.

Some possibilities (like print-screening and comparing images) sound just outright scary.
