One of the challenging problems in software development is the assuring of the correctness of the created software. During our previous research, we developed a framework for the simulation-based testing of software components SimCo that allows us to perform testing of component-based applications or its fragments. The SimCo was originally designed to perform the tests according to a given scenario in order to determine extra-functional properties of the components. However, it can be also used to test the correctness of the component behaviour. For this purpose, there are also other ways - the model checking tools, such as java pathfinder. We want to compare the strengths and weaknesses of the two approaches as represented by the SimCo and the java pathfinder. In this paper, the results of the comparison of these two testing methods on a case study using the implementation of the FTP protocol are discussed.

The work presented in this paper describes an approach used to develop SysML modeling patterns to express the logical behavior of fault protection (FP), test the model's logic via fault injection simulations, and verify the system's logical design via model checking. A FP model was architected with collaborating Statecharts that captures interactions between relevant system components (error monitors, FP engine, devices) and system behavior abstractions. Development of a method to implement verifiable and lightweight executable FP models enables future missions to have access to larger fault test domains and verifiable design patterns.

Autonomic computing has been recognized as a valid approach to the development of large-scale self-managing complex systems. The Autonomic System Specification Language (ASSL) is an initiative for the development of autonomic systems where we approach the problem of formal specification, validation, and code generation of such systems within a framework. As part of our research on ASSL, we have developed and investigated different approaches to software verification. Currently, the latter is possible via built-in consistency checking and functional testing where handling logical errors is a daunting task. In this paper, we discuss our work on model checking with NASA's java pathfinder tool, which is an explicit-state model checker that works directly on the generated java code. We propose optional automatic generation of test drivers in the form of pathfinder API calls seeded in the ASSL-generated code.

随着人们对软件可靠性、安全性的要求越来越高，软件测试技术的发展也受到了越来越多的重视，模型检测技术是一种形式化自动验证技术，目的是确保系统设计规范正确性的。 JPF（java pathfinder）是显式的java字节码模型检测工具，它是一个特殊的java虚拟机，理论上，它能够执行程序中所有可能存在的路径，主要适用于难以检测的多线程程序中的并行错误，如死锁和未处理的异常。JPF提供了选择生成器、指令工厂、属性系统、MJI、Listeners以及报告系统等多种扩展方式。 SPF是JPF的一个扩展项目，在SPF中，程序执行时用符号输入来代替多个具体的输入值，程序中变量的值由符号表达式表示，通过分析不同表达式的执行路径来生成各个分支的约束条件，这些约束条件由off-the-shell求解器来确定，并且进行路径可行性分析和生成测试输入。SPF与JPF模型检测器紧密集成，JPF框架为SPF提供了系统级的探索符号程序路径，不同的线程交错及出现在代码中的其它形式的不确定性。本文是基于SPF的软件模型检测工具的分析，深入分析了java字节码的运行实现机制，加强SPF的系统状态分析功能，以便发现系统中存在的新的漏洞。另外分析并研究了SPF处理复杂的数学约束、外部库的调用以及符号字符串的分析功能，通过设计的实例验证了SPF能够有效的解决循环和递归程序中的路径覆盖问题，以及SPF符号执行比具体执行具有较高的代码覆盖率。

Currently, a single Unmanned Aerial System (UAS) requires several humans managing different aspects of the problem. Human roles often include vehicle operators, payload experts, and mission managers [1-3]. As a step toward reducing the number of humans required, it is desirable to reduce operator workload through effective distributed control, augmented autonomy, and intelligent user interfaces. Reliably doing this requires various roles in the system to be modeled. These roles naturally include the roles of the humans, but they also include roles delegated to autonomy and software decision-making algorithms, meaning the GUI and the unmanned aerial vehicle. This paper presents a conceptual model which models the roles of complex systems as a collection of actors, running in parallel. Results from applying this model to the UAS-enabled Wilderness Search and Rescue (WiSAR) domain indicate (a) it is possible to model the entire WiSAR system at varying degrees of abstraction (b) that building and evaluating the model provides insight into the best practices of WiSAR teams and (c) a way to model human machine interactions that works directly with the java pathfinder model checker to detect errors.

Model checking agent programming languages

In this paper we describe a verification system for multi-agent programs. This is the first comprehensive approach to the verification of programs developed using programming languages based on the BDI (belief-desire-intention) model of agency. In particular, we have developed a specific layer of abstraction, sitting between the underlying verification system and the agent programming language, that maps the semantics of agent programs into the relevant model-checking framework. Crucially, this abstraction layer is both flexible and extensible;not only can a variety of different agent programming languages be implemented and verified, but even heterogeneous multi-agent programs can be captured semantically. In addition to describing this layer, and the semantic mapping inherent within it, we describe how the underlying model-checker is driven and how agent properties are checked. We also present several examples showing how the system can be used. As this is the first system of its kind, it is relatively slow, so we also indicate further work that needs to be tackled to improve performance.

java pathfinder (JPF) is an explicit-state model checker for java programs. JPF implements a backtrackable java Virtual Machine (JVM) that provides non-deterministic choices and control over thread scheduling. JPF is itself implemented in java and runs on top of a host JVM. JPF represents the JVM state of the program being checked and performs three main operations on this state representation: bytecode execution, state backtracking, and state comparison. This paper summarizes four extensions that we have developed to the JPF state representation and operations. One extension provides a new functionality to JPF, and three extensions improve performance of JPF in various scenarios. Some of our code has already been included in publicly available JPF.

Recently there has been a proliferation of tools and languages for modeling multi-agent systems (MAS). Verification tools, correspondingly, have been developed to check properties of these systems. Most MAS verification tools, however, have their own input language and often specialize in one verification technology, or only support checking a specific type of property. In this work we present an extensible framework that leverages mainstream verification tools to successfully reason about various types of properties. We describe the verification of models specified in the Brahms agent modeling language to demonstrate the feasibility of our approach. We chose Brahms because it is used to model real instances of interactions between pilots, air-traffic controllers, and automated systems at NASA. Our framework takes as input a Brahms model along with a java implementation of its semantics. We then use java pathfinder to explore all possible behaviors of the model and, also, produce a generalized intermediate representation that encodes these behaviors. The intermediate representation is automatically transformed to the input language of mainstream model checkers, including PRISM, SPIN, and NuSMV allowing us to check different types of properties. We validate our approach on a model that contains key elements from the Air France Flight 447 accident.

Comparing Metaheuristic Algorithms for Error Detection in java Programs

Model checking is a fully automatic technique for checking concurrent software properties in which the states of a concurrent system are explored in an explicit or implicit way. The main drawback of this technique is the high memory consumption, which limits the size of the programs that can be checked. In the last years, some researchers have focused on the application of guided non-complete stochastic techniques to the search of the state space of such concurrent programs. In this paper, we compare five metaheuristic algorithms for this problem. The algorithms are Simulated Annealing, Ant Colony Optimization, Particle Swarm Optimization and two variants of Genetic Algorithm. To the best of our knowledge, it is the first time that Simulated Annealing has been applied to the problem. We use in the comparison a benchmark composed of 17 java concurrent programs. We also compare the results of these algorithms with the ones of deterministic algorithms.
