    Mutation Operators for Decision Table-Based Contracts Used in Software Testing
    (Institute of Electrical and Electronics Engineers, 2020) Khalilov, Abbas; Tuğlular, Tuğkan; Belli, Fevzi
    The Design by Contract technique allows developers to improve source code with contracts, and testing using contracts helps to identify faults. However, the source code of the program under test is not always available. With black-box testing, it is possible to generate contracts from specifications of the software. In this paper, we apply mutation analysis on a model of a given specifications, where mutants are initially gained by applying proposed in this paper certain mutation operators on corresponding model, and then mutated specifications are examined. © 2020 IEEE.

    Towards Uniform Modeling and Holistic Testing of Hardware and Software
    (Institute of Electrical and Electronics Engineers Inc., 2019) Kılınççeker, Onur; Belli, Fevzi
    This paper introduces an approach to uniform modeling and testing of hardware and software systems and their faults. As an example, for hardware under consideration, designs at a behavioral level will be used, implemented in Hardware Description Language (HDL). For software, an example will be borrowed from a graphical user interface design. Both examples will be modeled by finite state machines. The mutation of these models leads to lucid hardware and software fault models, respectively. Original models and their mutants will then be used to generate test cases for positive testing and negative testing, respectively, forming a holistic test strategy. A positive test is supposed to validate the system under legal (expected, regular) circumstances, whereas a negative test checks the behavior of the system under illegal (unexpected, irregular) situations. Non-trivial examples are used to validate and analyze the approach with respect to uniform modeling and testing capability. © 2019 IEEE.

    Protocol-Based Testing of Firewalls
    (Institute of Electrical and Electronics Engineers Inc., 2009) Tuğlular, Tuğkan; Belli, Fevzi
    A firewall is the most important tool of network security defense. Its proper functioning is critical to the network it protects. Therefore a firewall should be tested rigorously with respect to its implemented network protocols and security policy specification. We propose a combined approach for test case generation to uncover errors both in firewall software and in its configuration. In the proposed approach, abstract test cases are generated by mutating event sequence graph model of chosen network protocol and filled with values from policy specification by using equivalence partitioning and boundary value analysis. A case study is presented to validate the presented approach.
