Automated test data generation is an important method for the verification and validation of UML/OCL specifications. In this paper, we present an extension of DNF-based test case generation methods to class models and recursive query operations on them. A key feature of our approach is an implicit representation of object graphs avoiding a representation… (More)

! Abstract—We apply automata theory to specifying behavioral interfaces of objects and show how to check schedulability and compatibility of real time asynchronous objects. The behavioral interfaces of real time objects specify (the order and timings of) the messages an object may send and receive. Each object is checked against its behavioral interface;… (More)

This paper deals with test case selection from axiomatic specifications whose axioms are quantifier-free first-order formulae. Test cases are modeled as ground formulae and any specification has an exhaustive test data set whose successful submission means correctness, provided that the software under verification can be modeled as a first-order structure… (More)

We propose a theoretical framework for testing concurrent systems from true concurrency models like Petri nets or networks of au-tomata. The underlying model of computation of such formalisms are labeled event structures, which allow to represent concurrency explicitly. The activity of testing relies on the definition of a conformance relation that depends… (More)

Model-based testing has mainly focused on models where currency is interpreted as interleaving (like the ioco theory for labeled transition systems), which may be too coarse when one wants concurrency to be preserved in the implementation. In order to test such concurrent systems, we choose to use Petri nets as specifications and define a concurrent… (More)

— In this paper, we present a temporal logic called F whose interpretation is over Input Output Symbolic Transition Systems (IOSTS). IOSTS extend transition systems to communications and data in order to tackle communications with system environment. F is then defined as an extension of temporal logic CT L * (a temporal logic which mixes together the… (More)

Message Sequence Charts are a widely used formalism for describing scenarios a communicating system must be able to perform. We study in this paper different formal frameworks for testing from MSCs. We first consider a setting where all the processes of the system can be controlled and observed globally. Then we study a setting where the system is tested… (More)

This paper deals with test case selection from axiomatic specifications whose axioms are quantifier-free first-order formulas with equality. We first prove the existence of an ideal exhaustive test set to start the selection from. We then propose an extension of the test selection method called axiom unfolding, originally defined for algebraic… (More)

SUMMARY We propose a theoretical testing framework and a test generation algorithm for concurrent systems specified with true concurrency models, such as Petri nets or networks of automata. The semantic model of computation of such formalisms are labeled event structures, which allow to represent concurrency explicitly. We introduce the notions of strong… (More)

In this paper, we provide a general setting under which results of normal-ization of proof trees such as, for instance, the logicality result in equational reasoning and the cut-elimination property in sequent or natural deduction calculi, can be unified and generalized. This is achieved by giving simple conditions which are sufficient to ensure that such… (More)
