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.

Web services composition is a new software development paradigm, and it is a key point to achieve service-oriented computing currently. For meeting the QoS requirements of consumers, this paper presents the QoS calculation rules and formalizes the services composition as the combinatorial optimization problem. In order to solve services composition, a new algorithm based on QPSO algorithm is proposed, which is called Hybrid QPSO algorithm and the correctness, feasibility, and effectiveness of the algorithm are demonstrated using the experiments. © 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.

Nowadays, with the prevalence of Web applications, more and more services and information are available over the Internet while their correctness, security and reliability are often crucial to the success of business and organizations. Web testing is one of the methods to ensure the Web security. However, due to the special characters of Web applications, traditional testing methods are not suitable for Web testing in many aspects. A typical Web application consists of two tiers: the client, the server. Most existing works consider Web applications testing from an external or a user's view, not taken the interactions and the behaviors of the server side into account. In this paper, special care on the interactions and the behaviors of server side is paid, and an approach to model composition and testing Web applications is proposed. FSMs are used to model Web applications from the user's side, and the server's side, respectively. Then, synchronous product was employed as a tool to construct a composition of FSMs. Finally, based on the composition of FSM, test generation is given out which satisfies the corresponding coverage criteria. © 2011 IEEE.

Service composition is an important means for integrating the individual Web services to create new value added systems that can satisfy complex requirements. However, it is a challenge to analyze security requirements for those applications due to the uncertainty factors in distributive environment. This paper proposes an approach to modeling and analyzing security requirements of service composition. Petri nets are used to model the different components of service composition, the dynamic matching strategy of service composition is proposed. Aspect-orientation is used to weave the security requirements into service composition, which includes evaluation concern, authorization, security level outputting and access outputting. The operation semantics and related theories of Petri nets help prove its effectiveness and correctness. An example explains the modeling and analyzing process of service composition, and a series of experiments are done to explain that the use of aspects for analyzing security requirements of service composition is more efficient than conventional techniques. © 2011 IEEE.

Regression testing is a hot research area for Web service composition, which has direct impact on QoS of applications. This paper proposes an aspect-oriented regression test technique for analyzing functionalities of service composition. An extended version of Petri net is proposed as the underlying formalism. Services and components are modeled by Petri nets, service evolution is specified as crosscutting concerns, and in turn woven into the testing model of service composition by following weaving rules. A regression testing algorithm of service composition is designed. Theories of Petri nets help prove the effectiveness of the testing method. A case study shows that the approach simplifies the process of testing, and improves its efficiency as well.

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.

A CPN-based software testing approach

As a graphical and mathematical modeling tool, CPN (Colored Petri Net) is often used to describe the transition of states for an information system. The advantage of CPN model is that the model can be simulated dynamically. This paper presents an approach to generating test cases based on a transition graph of CPN model. The transition graph provides a solid basis for test cases generation in a form that can be easily manipulated. The case for vending machine illustrates the effectiveness of this method. © 2011 ACADEMY PUBLISHER.

TCPNIA (Timed Colored Petri Nets with Inhibitor Arcs, TCPNIA) is a model for specifying real-time embedded systems. It integrates features of colored Petri nets, timed Petri nets and inhibitor arcs. The methods for modeling modules of systems using TCPNIA are proposed. A depth-first scheduling algorithm for TCPNIA is proposed. The system level resource's influence to schedulable path is considered. Different data in tokens will change an execution path and call different data operational functions. The influence from data operational functions is considered in the scheduling algorithm. The time requirement upper bound of a schedulable path can be calculated in the algorithm. Tasks' parallel executions have been considered when the time upper bound of the path is calculated. The soundness of the algorithm is proved. The time and space complexities of the algorithm are also analyzed. The compositional conditions and method for composing schedulable path are given. A case study shows the applicability and feasibility of the method. © 2011 ACADEMY PUBLISHER.

An application of ontology to test case reuse

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 Protege Ontology Editor and described by OWL (Web Ontology Language). At last, an example to illustrate the application of this method is to be discussed.
