Conference Object Sonlu Durum Makinelerinin Fourier Analizi Tabanlı Sınanması(CEUR Workshop Proceedings, 2018) Takan, Savaş; Ayav, TolgaSonlu durum makinesi (FSM), devre ve yazılım testlerinde yaygın kullanıma sahip bir modelleme tekniğidir. FSM'lerin testi için literatürde çeşitli yöntemler bulunmakla birlikte, modellerin büyümesi sonucu test kümesinin büyüklüğü, hata yakalama oranı ve test üretim süresi gibi konularda yüksek başarıma sahip alternatif test yöntemlerine ihtiyaç bulunmaktadır. Bu çalışma ikili fonksiyonların Fourier analizine dayanan yeni bir test oluşturma yöntemi önermektedir. İlk sonuçlar, fonksiyonun frekans bileşenlerinden yararlanarak oluşturulan test takımının daha yüksek bir performansa sahip olduğunu göstermektedir. Önerilen yöntem, karakteristiği, maliyeti ve hata yakalama oranı üzerinden literatürden seçilen iki yöntemle karşılaştırılmıştır.Conference Object Citation - Scopus: 1Mutation-Based Evaluation of Weighted Test Case Selection for Firewall Testing(Institute of Electrical and Electronics Engineers Inc., 2011) Tuğlular, Tuğkan; Gerçek, GürcanAs part of network security testing an administrator needs to know whether the firewall enforces the security policy as expected or not. In this setting black-box testing and evaluation methodologies can be helpful. In this paper we employ a simple mutation operation namely flipping a bit to generate mutant firewall policies and use them to evaluate our previously proposed weighted test case selection method for firewall testing. In the previously proposed firewall testing approach abstract test cases that are automatically generated from firewall decision diagrams are instantiated by selecting test input values from different test data pools for each field of firewall policy. Furthermore a case study is presented to validate the proposed approach. © 2011 IEEEConference Object Citation - WoS: 3Citation - Scopus: 9Boolean Differentiation for Formalizing Myers' Cause-Effect Graph Testing Technique(Institute of Electrical and Electronics Engineers Inc., 2015) Ayav, Tolga; Belli, FevziCause-Effect Graph Testing is a popular technique used for almost four decades. Based on Boolean algebra, this technique assists deriving test cases from a given specification informally written in a natural language. The present paper suggests Boolean differentiation for formalizing this technique. The new approach is applied to an example, borrowed from G. Myers, for demonstrating and analyzing its features. Evaluations show that the new approach outperforms Myers' approach in terms of the detected faults per test cases.
