Abstract: A hardware and/or software facility for automated application compatibility testing. The facility automatically detects visual discrepancies between rendered versions of a web page produced by different browsers. The facility may identify differences in a web page rendered by two or more browsers by progressively comparing, for each browser, the corresponding visual elements of the web page without comparing the elements to any predetermined expected results. The facility may identify functional differences in the web page across the tested browsers. The facility generates a human-readable report of the visual and/or functional differences between the tested browsers.
