Conference Object Citation - WoS: 3Citation - Scopus: 2Heterogeneous Modeling and Testing of Software Product Lines(IEEE, 2021) Belli, Fevzi; Tuğlular, Tuğkan; Ufuktepe, EkincanSoftware product line (SPL) engineering is a widely accepted approach to systematically realizing software reuse in an industrial environment. Feature models, a centerpiece of most SPL engineering techniques, are appropriate to model the variability and the structure of SPLs, but not their behavior. This paper uses the idea to link feature modeling to model-based behavior modeling and to determine the test direction (top-down or bottom-up) based on the variability binding. This heterogeneous modeling enables a holistic system testing for validating both desirable (positive) and undesirable (negative) properties of the SPL and variants. The proposed approach is validated by a non-trivial example and evaluated by comparison.Conference Object Citation - WoS: 7Citation - Scopus: 8Models in Graphical User Interface Testing: Study Design(Institute of Electrical and Electronics Engineers, 2020) Silistre, Alper; Kılınççeker, Onur; Belli, Fevzi; Challenger, Moharram; Kardaş, GeylaniModel-based GUI testing is an important concept in Software GUI testing. Manual testing is a time-consuming labor and heavily error-prone. It has several well-accepted models that Software Testing community has been working and contributing to them for many years. This paper reviews different models used in model-based GUI testing and presents a case study with a proposed approach for how to convert several well-accepted models to ESG (Event Sequence Graphs) to generate test cases and execute them with an aim to consolidate past and future works in a single model. © 2020 IEEE.Conference Object Utilizing Modeling Approach Patterns in the Embedded Software Industry(Institute of Electrical and Electronics Engineers Inc., 2019) Akdur, Deniz; Demirörs, OnurTo cope with the growing complexity of software-intensive embedded system development, modeling is a widely used approach. The modeling approaches in the embedded software industry vary depending on many modeling characteristics (e.g., purpose, modeling rigor, medium type used, modeling stakeholder profile, etc.). In the light of our previous studies, we have identified modeling approach patterns of embedded software development projects and constructed a characterization model. This model not only identifies and defines modeling approach patterns of the stakeholder in embedded software development projects, but also gives recommendations for commonsense modeling practices. In this article, one of the application results of this characterization model, which was performed in Defense & Aerospace sector is presented. The model was successfully applied to the case, in which a series of both structured and semi-structured interviews with 17 embedded software professionals were conducted. The results show that identification of individual patterns provide insight for improvement both for individuals as well as larger units of operations such as projects and organizations.Conference Object Event Sequence Graph-Based Feature-Oriented Testing: a Preliminary Study(Institute of Electrical and Electronics Engineers Inc., 2018) Tuğlular, TuğkanThis paper proposes a model-based approach for feature-oriented testing using event sequence graphs (ESGs). ESGs are used to generate test cases automatically for positive and negative testing. To fit ESG models to feature-oriented testing, two new improvements on ESGs are proposed. The first improvement is on repetitive use of refinement ESG and the second improvement is saving state in an ESG and passing it to the following ESG. This is a work towards communicating hierarchical ESGs. The preliminary results demonstrate the feasibility of the proposed approach. The proposed approach improves testability of features.
