Parallel Specification-Based Testing for Concurrent Programs

The paper proposes a new testing technique for concurrent programs. The technique is a specification-based testing. For a formal specification S and a concurrent program P , state sequences are generated from P and checked to be accepted by S. We suppose that S is specified in Maude and P is implemented in Java. Java Pathfinder (JPF) and Maude are then used to generate state sequences from P and to check if such state sequences are accepted by S, respectively. Even without checking any property violations with JPF, JPF often encounters the notorious state space explosion while only generating state sequences. Thus, we propose a technique to generate state sequences from P and check if such state sequences are accepted by S in a stratified way. A tool is developed to support the proposed technique that can be processed naturally in parallel. Some experiments demonstrate that the proposed technique mitigates the state space explosion, which cannot be achieved with the straightforward use of JPF.

“…Verification with a highly abstracted scheduling policy has been a main stream in research and practice of modelchecking multitasking programs [20], [27], [32], [38], [44], [47]. Works in this category assume arbitrary interleavings among tasks, but reduce verification complexity by either using partial-order reduction, limiting the number of context switches among tasks, or applying CEGAR [10], [47]. These approaches suffer from a high false-alarm rate and/or additional cost for refinements caused by allowing arbitrary sequences of task executions.…”

“…Nevertheless, formal verification approaches for multitasking embedded software have mostly focused on the control logic separately from the OS [1], [13], [30], [35], [38]- [40], [45], [47], which often produces a large number of false alarms due to the over-approximation of the environment, including the operating system. For example, the application program shown in Figure 1 has a unique execution trace due to the scheduling decision from its underlying operating system.…”

OS-Aware Interaction Model for the Verification of Multitasking Embedded Software

As the behavior of multitasking embedded software is dependent on the underlying operating system(s), rigorous and efficient verification in this domain requires models of operating systems (OS) that enable OS-aware verification of application programs at reduced cost. However, the heterogeneity of the languages used for OS models and of the program source code makes it difficult to compose these seemingly independent components and thus requires translation of one language into another, causing various issues in verification. To alleviate this problem, we propose a hybrid approach that composes formal OS models with application programs in an interaction model. Based on typical OS-application interaction behavior, our interaction model is a composition framework that connects an OS model to application programs as long as they share the same Application Program Interface (API). It provides seamless composition of two heterogeneous software artifacts by formulating source code annotations based on control-flow analysis and by synchronizing state transitions over API function calls to regulate the context switching of multitasking programs. A prototype implementation of the interaction model was applied to eight benchmark programs of the Erika OS and a control program with real-scale complexity from the automotive domain. It was shown that the framework supports systematic and effective verification of multitasking embedded software, which has not been possible using code-level model checking.

“…The above traditional measurement methods describe the complexity of software from different aspects. All focus on analyzing the local structure and characteristics of functional individuals in the software system like classes, methods, etc., and lack a global measurement of software structure [6][7][8][9][10].…”

“…The emergence of complex systems and complex networks [10][11][12][13], which emphasize a holistic approach to the system rather than focusing on local aspects, has provided a valuable perspective and a unique research dimension for understanding a software system. Unlike the traditional "reduction method" used in software development, the complex system theory emphasizes the global features of a system.…”

Package Network Model: A Way to Capture Holistic Structural Features of Open-Source Operating Systems

et al. 2019

Open-source software has become a powerful engine for the development of the software industry. Its production mode, which is based on large-scale group collaboration, allows for the rapid and continuous evolution of open-source software on demand. As an important branch of open-source software, open-source operating systems are commonly used in modern service industries such as finance, logistics, education, medical care, e-commerce and tourism, etc. The reliability of these systems is increasingly valued. However, a self-organizing and loosely coupled development approach complicates the structural analysis of open-source operating system software. Traditional methods focus on analysis at the local level. There is a lack of research on the relationship between internal attributes and external overall characteristics. Consequently, conventional methods are difficult to adapt to complex software systems, especially the structural analysis of open-source operating system software. It is therefore of great significance to capture the holistic structure and behavior of the software system. Complex network theory, which is adequate for this task, can make up for the deficiency of traditional software structure evaluation methods that focus only on local structure. In this paper, we propose a package network model, which is a directed graph structure, to describe the dependency of open-source operating system software packages. Based on the Ubuntu Kylin Linux Operating system, we construct a software package dependency network of each distributed version and analyze the structural evolution through the dimensions of scale, density, connectivity, cohesion, and heterogeneity of each network.
