Modeling web application for cross-browser compatibility testing

Due to the increasing popularity of web applications and modern browsers, the cross-browser compatibility issues are becoming a prevalent problem. Cross-browser incompatibilities range from minor differences in appearance to critical functional failures. Existing tools and techniques hardly help developer to detect such issues exactly. This paper presents a model of interaction transition (ITM) to characterize the behavior of web pages containing interactions, and gives the relevant definitions and constraints. Finally, we illustrate its effectiveness in detecting CBC interaction problems by analyzing a case.
