US Patent 8151276 Test script transformation analyzer with change guide engine

A script analyzer with change guide generates accurate test scripts for evolving applications. Applications often have complex graphical user interfaces for which the permutations and combinations of GUI elements give rise to an enormous field of potential commands and command sequences to be tested. Furthermore, these applications change over time, rendering prior test scripts unworkable. The script analyzer automatically generates new test scripts to reliably test subsequent application versions, while greatly reducing the time, cost, and resource expenditures needed to arrive at subsequent application versions.
