Model Checking User Interfaces

User interfaces are crucial for the success of most software projects. As software grows in complexity there is a similar growth in the user interface com-plexity which leads to bugs which may be difficult to find by means of testing. In this paper we use the method of automated model checking to verify user interfaces with respect to a formal specification. We present an algorithm for the automated abstraction of the user interface model of a given system, which uses asynchronous and interleaving composition of a number of programs. This technique was successful at verifying the user interface of case study and brings us one step forward towards push button verification
