The Web service composition (WSC) has been widely used in Service-Oriented Architecture (SOA), which is an effective integration of the distributed and heterogeneous business applications. In contrast to the component-based software, dynamic reconfiguration occurs more frequently in Web services-based software for self-adapting and self-managing their computing capabilities due to the uncertainty of dynamic Internet environment. Verifying these stochastic and nondeterministic behaviors is becoming a hot topic in model checking of Web services (WSs) application engineering. Abstraction refinement technique as an effective approach to alleviating the state explosion problem is particularly suitable for verifying the complex WSC. In this paper, we extend the classical abstraction refinement technique CEGAR (Counterexample-guided abstraction refinement) to make quantitative verification of WSC applicable and efficient. To model WSC, a probabilistic service behavior model (p-SBM) is proposed in form of Markov Decision Process (MDP). To verify WSC, the abstraction is defined by means of a quotient on states with respect to some probabilistic equivalence relation. Once counterexample is produced in the abstract model, verifying whether the counterexample is real or spurious is carried out. Based on the counterexample-guided technique, an iterative abstraction refinement process is performed to progressively refine the abstract model until either there is no abstract counterexample or a valid counterexample is verified. The case studies which are discussed throughout the paper demonstrate that our approach takes advantages than the traditional approaches. © 2011 IEEE.

Test case is one of the most important part of software testing. Reusing available test cases is an effective means to reduce the cost and improve the efficiency of software testing. In order to efficiently reuse test cases, a unified and standard format to describe test cases is needed. Therefore, this paper presents a reusing method based on ontology. The test case ontology is created by Prot00E9;Ontology Editor and described by OWL (Web Ontology Language). At last, an example to illustrate the application of this method is to be discussed. © 2011 IEEE.

In this paper, we propose a test generation method that combines compositional reasoning theory and counterexample guided abstraction refinement framework. Firstly, the abstract model of system is produced by composing abstract components, then the abstract test cases can be generated by model checking based on abstract model, finally, the concrete test case of the complete original system is generated by refining the abstract model. The abstraction refinement keeps the state space small enough to alleviate the state space explosion problem. © 2011 IEEE.

As Web services are becoming more and more complex, there is an increasing concern about how to guarantee the correctness and safety of Web services composition. This has driven many researchers to study the performance analysis of dynamic atomic service selection, as well as functional verifications. In this paper, we focus on not only modeling the behaviors of atomic service, but also verifying the properties in a quantitative way. First, we apply probabilistic timed model checking to model and verify the behaviors of atomic service by extending interface automata, and propose a technique to formally estimate software performance which exhibits stochastic behaviors with time constrains. Second, the probabilistic timed computation tree logic (PTCTL) formulae are used to express the reliability properties. Third, a failure may occur stochastically when an invocation is triggered through interface operation. We present an internal interaction model, based on which we can dynamically pick out a highest reliable execution sequence for Web services composition. Finally, a case study is demonstrated and experimental results are discussed. In conclusion, our approach provides with an underlying guideline for Web services composition. © 2011 IEEE.

As Web applications evolve, their structure may be-come more and more complex. Web frameset is used to organize multiple frames and nested framesets to make the layout of some Web pages more identical and bring the development of Web applications easier, which was wildly used in today's Web applications. How to model and verify the frameset-based Web applications is a challenge. In this paper, special care on Web frameset is paid and an approach to modeling and verifying Web application's navigation with Web frameset is proposed. The Composition semantics of Web Frame-set was give out which can be used to construct complex Web Frameset. Additionally, FSM was employed to describe our models with Web Frameset. Then, we transform FSM model into Kripke structure. Finally, taking advantage of the properties which were generated, we verified our model with Web Framesets. And according to results of verification, we improve our models. © 2011 IEEE.

UPnP is a universal plug and play technology which is widely used in the digital family network. The UPnP security ceremonies expend the UPnP technology to meet the important security requirement. This paper introduces a formal method named the Petri Net, using its advantage such as intuitive graphical representation and rigorous mathematical theory to model the security control of the UPnP security ceremonies. This paper simulates the security control in actual security system, using occurrence step and transition sequence of Petri Net model to analyze the accessibility of model and verify the non-repudiation and security of system. © 2011 IEEE.

There are many variants of Petri net at present, and some of them can model system with both function and performance specification, such as stochastic Petri net, and generalized stochastic Petri net. In order to address the issue of modeling system with probabilistic behaviors, a kind of Petri net with probability (probabilistic Petri net, PPN) is proposed in this paper. Then an action-based PCTL is developed to interpret logical semantics for PPN system. The usefulness of PPN system is illustrated by modeling and specifying an elaborate model of travel arrangements workflow. © 2011 IEEE.

This paper proposes a business process testing scenario generation based on test cases composition. Just like path oriented testing technique in structure testing area, this testing method focuses on finding the logical error in the process implementation according to the formal business process presentation. The test cases against a node of process designed by the techniques such as boundary value analysis, equivalence partitioning and so on, may not easily find the errors in the special business process tends. These test cases are modeled as TCN (Test Cases Nets) with a CPN (Colored Petri Nets) in this paper. The BPSN (Business Process Scenario Net) is built by composing the existing TCN. The generation technique of the test scenario for basis path testing for a business process according to the BPSN is discussed. We exemplify our approach in an ATM system that has a rich set of interactions with its users.
