To assure quality of software products from SPLs, products need to be tested systematically. However, testing every product variant in isolation is generally not feasible for large number of product variants. An approach to deal with this issue is to use incremental testing, where test artifacts that are developed for one product are reused for another product which can be obtained by incrementally adding features to the prior product. We propose a novel model-based test generation approach for products developed using SPL that follows incremental testing paradigm. First, we introduce Featured Event Sequence Graphs (FESGs), an extension of ESGs, that provide necessary definitions and operations to support commonalities and variabilities in SPLs with respect to test models. Then we propose a test generation technique for the product variants of an SPL, which starts from any product. The proposed technique with FESGs avoids redundant test generation for each product from SPL. We compare our technique with in-isolation testing approach by a case study.Conference Object Özellik Yönelimli Ürün Konfigürasyonlarının Olay Sıra Çizgeleri ile Doğrulanması(CEUR Workshop Proceedings, 2018) Tuğlular, Tuğkan; Belli, Fevzi; Öztürk, DilekThis study attempts to suggest an approach to systematically test potentially very large number of product variants in feature-oriented software. Feature-oriented software forms a popular concept to efficiently realize software reuse. Developing feature-oriented software is well accepted to accomplish software reuse in an efficient way. Developing product variants by exploiting software reuse requires verification of these variants by exploiting test reuse. However, the reuse of tests in the verification of variants is an underworked topic. In this study, we propose a model-based approach to top-down testing of feature-oriented software that does not have dependency or conflict between features. In the case study, event sequence graphs (ESGs) are used to model the software under consideration and then to generate test cases for positive and negative testing. The generated tests are executed via SahiPro web test automation tool, of which scripts are also automatically generated from ESGs.
