Using the Model Checker Spin for Web Application Design

The number of Web applications handling online transaction is increasing, but verification of the correctness of the Web application design has been done manually. This paper proposes a method for modeling Web applications using two finite-state automata, i.e., a page automaton which specifies Web page transitions, and an internal state automaton which specifies internal state transitions of the Web application. An example Web application is modeled by the proposed method and checked using the model checker Spin.
