    Model-Based Contract Testing of Graphical User Interfaces
    (Institute of Electronics, Information and Communication Engineers, 2015) Tuğlular, Tuğkan; Linschulte, Michael; Belli, Fevzi; Müftüoğlu, Arda
    Graphical User Interfaces (GUIs) are critical for the security, safety and reliability of software systems. Injection attacks, for instance via SQL, succeed due to insufficient input validation and can be avoided if contract-based approaches, such as Design by Contract, are followed in the software development lifecycle of GUIs. This paper proposes a model-based testing approach for detecting GUI data contract violations, which may result in serious failures such as system crash. A contract-based model of GUI data specifications is used to develop test scenarios and to serve as test oracle. The technique introduced uses multi terminal binary decision diagrams, which are designed as an integral part of decision tableaugmented event sequence graphs, to implement a GUI testing process. A case study, which validates the presented approach on a port scanner written in Java programming language, is presented.

    Gui-Based Testing of Boundary Overflow Vulnerability
    (Institute of Electrical and Electronics Engineers Inc., 2009) Tuğlular, Tuğkan; Müftüoğlu, Can Arda; Kaya, Özgür; Belli, Fevzi; Linschulte, M.
    Boundary overflows are caused by violation of constraints, mostly limiting the range of internal values of a program, and can be provoked by an intruder to gain control of or access to stored data. In order to countermeasure this well-known vulnerability issue, this paper focuses on input validation of graphical user interfaces (GUI). The approach proposed generates test cases for numerical inputs based on GUI specification through decision tables. If boundary overflow error(s) are detected, the source code will be analyzed to localize and correct the encountered error(s) automatically.
