Article Citation - WoS: 7Citation - Scopus: 9Input Contract Testing of Graphical User Interfaces(World Scientific Publishing Co. Pte Ltd, 2016) Tuğlular, Tuğkan; Belli, Fevzi; Linschulte, MichaelUser inputs are critical for the security, safety, and reliability of software systems. This paper proposes a new concept called user input contracts, which is an integral part of a design-by-contract supplemented development process, and a model-based testing approach to detect violations of user input contracts. The approach generates test cases from an input contract integrated with graph-based model of user interface specification and applies them to the system under consideration. The paper presents a proof-of-concept tool that has been developed and used to validate the approach by experiments. The experiments are conducted on a web-based system for marketing tourist services to analyze input robustness of system under consideration with respect to user input contracts.Article Citation - WoS: 1Citation - Scopus: 1Accounting for Product Similarity in Software Project Duration Estimation(World Scientific Publishing Co. Pte Ltd, 2016) Taştekin, Semra Yılmaz; Erten, Yusuf Murat; Bilgen, SemihWe extend an existing model proposed for estimating project duration for industrial projects in general, to software intensive systems projects. We show, through nine different cases studies from different sectors, that product similarity, measured in terms of requirements reuse, can be incorporated into that model to improve its applicability in software intensive systems projects.
