This work proposes an approach to randomly generate test sequences that might he used for comparison with existing GUI testing techniques to evaluate their efficiency. The proposed approach first models CUI under test by a finite state machine (FSM) and then converts it to a regular expression (RE). A tool based on a special technique we developed analyzes the RE to fulfill missing context information such as the position of a symbol in the RE. The result is a context table representing the RE. The proposed approach traverses the context table to generate the test sequences. To do this, the approach repeatedly selects a symbol in the table, starting from the initial symbol, in a random manner until reaching a special, finalizing symbol for constructing a test sequence. Thus, the approach uses a symbol coverage criterion to assess the adequacy of the test generation. To evaluate the approach, mutation testing is used. The proposed technique is to a great extent implemented and is available as a tool called PQ-Ran Test (PQ-analysis based Random Test Generation). A case study demonstrates the proposed approach and analyzes its effectiveness by mutation testing.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 Citation - WoS: 10Citation - Scopus: 13Regular Expression Based Test Sequence Generation for Hdl Program Validation(Institute of Electrical and Electronics Engineers Inc., 2018) Kılınççeker, Onur; Türk, Ercüment; Challenger, Moharram; Belli, FevziThis paper proposes a test sequence generation approach for behavioral model validation of sequential circuits implemented in Hardware Description Language (HDL). In the procedure of test sequence generation proposed in this study, Regular Expressions (REs) are utilized to model the behavior of the System Under Test (SUT). First, the HDL program is converted to a Finite State Machine (FSM). Then, the obtained FSM is transformed to RE which is represented by a Syntax Tree (ST). In this way, the test sequence generation problem is simplified to the tree traversal algorithm in which symbol and operator coverage criteria are satisfied. The required tools for test sequence generation are provided to automatize the whole procedure of the proposed approach. Also, a running example, based on a real-life-like Traffic Light Controller (TLC), validates the proposed approach and analyzes its characteristic features.
