The navigation of a web application is the possible sequences of web pages a user can visit. In the simplest case the next page is determined by the current page and the action (e.g. link, button) selected by the user. However, many web applications now incorporate adaptive navigation, where the next page also depends on the user's mode, for example whether they are a customer or an administrator, or depends on what pages the user has visited previously.Navigation models are useful for clarifying requirements and specifying implementation behavior. When a model is formal, it can also be used to generate design or implementation artifacts, and can be verified for properties such as broken links or length of navigation path. These uses are all important for the case of simple navigation, but even more important for adaptive navigation because of the added complexity. However, none of the current formal approaches can support adaptive navigation.In this paper we present an approach that uses Statecharts to formally model adaptive navigation, and show how important properties of a navigation model are verified using existing model-checking tools. We summarize the kinds of properties that can be checked with such a model, and describe how to use the Symbolic Model Verifier (SMV) tool to perform the verification. Finally, we use the Blockbuster® web site as a case study to demonstrate how our approach can uncover navigation problems that arise when new requirements are imposed.
