Following their previous work on extracting state-machines from AJAX applications, the authors proposed a Spin-based tool to verify invariants in AJAX state machines. The paper is very interesting and its treatment thorough. The paper starts by saying that AJAX is “credited with the 500% increase in Web users compared to a decade ago.”, the main factor being the improved user experience with rich Web application, i.e., their usability. However, “unpredictable contexts while running application might conceal faults that will break the design patterns” used by developers to ensure usability.
