Scripted GUI Testing with Ruby
If you need to automatically test a user interface, this book is for you. Whether it's Windows, a Java platform (including Mac, Linux, and others) or a web app, you'll see how to test it reliably and repeatably.

Many automated test frameworks promise the world and deliver nothing but headaches. Fortunately, you've got a secret weapon: Ruby. Ruby lets you build up a solution to fit your problem, rather than forcing your problem to fit into someone else's idea of testing.

This book is for people who want to get their hands dirty on examples from the real world and who know that testing can be a joy when the tools don't get in the way. It starts with the mechanics of simulating button pushes and keystrokes, and builds up to writing clear code, organizing tests, and beyond. more »
