Effective automated testing: a solution of graphical object verification

摘要

Recently, software testers have relied more on automated testing to test software. Automated testing method consists of three modules: test case design, execution, and verification. Yet, to accomplish these three phases, we are always in a dilemma due to a lack of a verification function. Nearly all the commercial automated testing tools cannot efficiently compare graphic objects though GUI (Graphic User Interface) software is now more crucial than text based user interface. This research develops a technique that aids automatic behavior verification for a particularly difficult problem: determining the correction of screen and paper output. Methodology to capture and compare the output is presented and a case study using Microsoft PowerPoint is described.
