in reply to Application for 'Quality Assurance'

I played recently with Win32::GuiTest. A neat module by Ernesto Guisado, already mentioned by monks. Great for sending random keystrokes and mouse clicks to your application. It does not offer, however, any help with learning the mouse moves or clicks (neither do I :-).

The script below is a demo monkey test, that beats on the Windows Calculator app.

When you start this kind of script on your machine, you may have a problem: it takes over your mouse cursor when sending the mouse clicks. If you programmed it for an hour's worth of clicks, started it, and then you changed your mind, how would you stop it?

I kludged a solution based on the Term::ReadKey module, which I wrapped in my ReadKeypress module, below. The script frequently checks whether you pressed the Esc key, and to do that, it activates the comand window from which you launched the script, and calls the nonblocking ReadKeypress::escape().

If anyone knows of a more elegant solution for this problem, please let me know.


Anyway, here goes the demo
