“…Finally, we are also evaluating support for conditional scenarios in the VTS language [8]. Essentially, conditional scenarios state that, whenever a matching for a sub-scenario (the antecedent) is encountered in a given trace, the same matching must be extensible to cover one in a set of consequent scenarios.…”

Modern software systems are increasingly complex and are controlling critical activities in many different domains. The traditional assumption that these systems will work in a controlled context is slightly vanishing. Therefore, it emerges the need of methodologies able to determine under what conditions desired goals will be achieved and behavioural strategies will be preserved despite (often unavoidable) adaptations.In this paper we use the cognitive psychology concept of schema to identify the set of properties that an adaptable system has to maintain when adapting to changed context. The methodology we propose, called AC-contract (Adaptable Code-contract), starts from high-level requirements and identifies properties that should hold locally on single parts of the system. Local properties are represented as contracts directly on the programming language. Specifically, AC-contract is able to embed logical propositions in the source code as annotations; moreover, it enables verification of adaptable code by exploiting a preprocessor that executes the annotations. The methodology is applied to a mobile application supporting travellers during their journey.

“…Visual Timed event Scenarios (VTS) (Braberman et al 2005;Alfonso et al 2004) is a visual language for expressing event-based requirements. In this language system events are considered any observable and interesting changes (from the point of view of the verification) during the system execution.…”

“…While one proposal is to construct a library of predefined LTL formulae from which a user can choose (Dwyer et al 1999), other works propose the specification of temporal properties through graphical formalisms (Smith et al 2001;Dillon et al 1994;Zanolin et al 2003;Alfonso et al 2004;Braberman et al 2005;Kugler et al 2005). Any of these solutions have advantages and disadvantages.…”

Graphical scenarios for specifying temporal properties: an automated approach

Temporal logics are commonly used for reasoning about concurrent systems. Model checkers and other finite-state verification techniques allow for automated checking of system model compliance to given temporal properties. These properties are typically specified as linear-time formulae in temporal logics. Unfortunately, the level of inherent sophistication required by these formalisms too often represents an impediment to move these techniques from "research theory" to "industry practice". The objective of this work is to facilitate the nontrivial and error prone task of specifying, correctly and without expertise in temporal logic, temporal properties.In order to understand the basis of a simple but expressive formalism for specifying temporal properties we critically analyze commonly used in practice visual notations. Then we present a scenario-based visual language called Property Sequence Chart (PSC) that, in our opinion, fixes the highlighted lacks of these notations by extending a subset of UML 2.0 Interaction Sequence Diagrams. We also provide PSC with both denotational and operational semantics. The operational semantics is obtained via translation into Büchi automata and the translation algorithm is implemented as a plugin of our CHARMY tool. Expressiveness of PSC has been validated with respect to well known property specification patterns.Keywords Scenario based notation · System requirements specification · Temporal properties specification Preliminary results appeared in (Autili et al. 2006a).M.
