Objects vs. Images: Choosing the Right GUI Test Tool Architecture

Chip Groder

Most popular GUI test tools are based on an object recognition architecture. They recognize and manipulate screen objects by communicating with the underlying GUI subsystem. A new breed of tools has been introduced in the past few years that implements an image recognition architecture. These tools use sophisticated image processing and OCR technology to recognize objects by their appearance on the display. Image recognition-based tools have distinct advantages in some environments, but object-based tools are a better choice in other situations. Join Chip Groder as he compares and contrasts the strengths and risks with each architecture and provides guidance to help you decide whether an object-based GUI tool or an image-based GUI tool—or perhaps both—will perform best and meet your test automation requirements.
