VISUAL CROSS-BROWSER LAYOUT TESTING METHOD AND SYSTEM THEREFOR

摘要

According to the invented method, web pages are rendered on virtual PC's using different combinations of operating systems and browsers. Rendered web pages are stored as digital color images. For each picture a specific set of features are calculated and compared against the feature of a baseline image. Regions containing differences are marked and stored. Detected differences are displayed as transparent windows on top of browser under test. Transparent windows are sections of baseline browser images. These sections comprise regions where feature error threshold has been exceeded.

1. A visual cross-browser testing method for testing web pages and web applications in a computer system, the method comprises the steps of:
providing a baseline image of a web page rendered by a baseline browser; extracting baseline image features from said baseline image; providing a test image of the web page rendered by browser under test; extracting the test image features from said test image; comparing the baseline image features and the test image features; marking up the regions with differences of the test image; and visualizing the regions with differences on said test image.
