Weighting Influence of User Behavior in Software Validation

Validation is an essential part of software development, and testing is a practical and widely used approach. The emerging methodology is model-based testing, in which test cases are derived from a model of software behaviour. In this paper we claim that also user behaviour should be taken into account for test planning purposes. We introduce a pragmatic approach called WSA, which derives the test cases from a state-based model, while also accounting for weights that consider relevance wrt user behaviour.
