This paper presents a methodology for generating a web service "stub" that simulates the behaviour of a real-world SOAP web service. The simulation is driven by a formal description of the original service's input and output parameters, messages, and ordering constraints between messages, using an extension of Linear Temporal Logic called LTL-FO+. This logic is rich enough to express complex...
This paper presents a formal framework to perform passive testing of service-oriented systems. Our approach uses the historical interaction files between web services to check the absence of faults. It uses a set of properties, that we call invariants, to represent the most relevant expected behaviour of the web services under test. Intuitively, an invariant expresses the fact that each time the system...
