La compartimentalización en asignaturas hace que en las mismas se trabaje normalmente en uno o dos niveles de abstracción, por lo que la visión global y transversal entre niveles a veces se pierde. La abstracción es un mecanismo mediante el cual la complejidad de un sistema informático es estratificada en niveles. Cada nivel define un interfaz de interacción con sus niveles vecinos ocultando al resto su implementación. Las asignaturas enseñan muy bien los interfaces y su implementación subyacente pero no las interacciones con el resto de los niveles. Este proyecto pretende romper esta tendencia. Para ello, se estudiará el modo de establecer una plataforma común de trabajo, y su respectivo material, con el objetivo de utilizarlo en múltiples asignaturas y dotar al alumnado de la visión global y transversal de los sistemas informáticos. 4 - Participantes en el proyecto Nombre y apellidos Correo Electrónico Departamento Centro/Institución Don José Luis Briz Velasco [email protected] Informática e Ingeniería de Escuela de Ingeniería y Sistemas Arquitectura Don Víctor Viñals Yúfera [email protected] Informática e Ingeniería de Escuela de Ingeniería y Sistemas Arquitectura Don Rubén Gran Tejero [email protected] Informática e Ingeniería de Escuela de Ingeniería y Sistemas Arquitectura Don Jesus Javier Resano Ezcaray [email protected] Informática e Ingeniería de Escuela de Ingeniería y Sistemas Arquitectura Doña María Villaroya Gaudó Maria.Villarroya@unizar.

  • A Framework for Evaluating Performance of Software Testing Tools
    INTERNATIONAL JOURNAL OF SCIENTIFIC & TECHNOLOGY RESEARCH VOLUME 9, ISSUE 02, FEBRUARY 2020 ISSN 2277-8616 A Framework For Evaluating Performance Of Software Testing Tools Pramod Mathew Jacob, Prasanna Mani Abstract: Software plays a pivotal role in this technology era. Due to its increased applicable domains, quality of the software being developed is to be monitored and controlled. Software organization follows many testing methodologies to perform quality management. Testing methodologies can be either manual or automated. Automated testing tools got massive acceptability among software professionals due to its enhanced features and functionalities than that of manual testing. There are hundreds of test automation tools available, among which some perform exceptionally well. Due to the availability of large set of tools, it is a herculean task for the project manager to choose the appropriate automation tool, which is suitable for their project domain. In this paper, we derive a software testing tool selection model which evaluates the performance aspects of a script-based testing tool. Experimental evaluation proves that, it can be used to compare and evaluate various performance characteristics of commercially accepted test automation tools based on user experience as well as system performance. Index Terms: Automated testing, Software testing, Test script, Testing Tool, Test bed, Verification and Validation. —————————— ◆ —————————— 1 INTRODUCTION S OFTWARE is advanced in recent days by enhancing its applicable domains. Software is embedded in almost all electronic gadgets and systems. In this scenario the quality of the software plays a significant role. The customer or end – user should be satisfied which is primarily depended on quality and capability of the software being developed.

    Alleviating Merge Conflicts with Fine-grained Visual Awareness Stanislav Levin Amiram Yehudai The Blavatnik School of Computer Science The Blavatnik School of Computer Science Tel Aviv University Tel Aviv University Tel-Aviv, Israel Tel-Aviv, Israel [email protected] [email protected] Abstract—Merge conflicts created by software team members dealing with conflicts, such as the multi-versioning technique working on the same code can be costly to resolve, and adversely described in [9]. Regardless of the method chosen, one thing affect productivity. In this work, we suggest the approach of remains painfully certain - a mishandled merge can lead to a fine-grained merge conflict awareness, where software team members are notified of potential merge conflicts via graphical variety of negative results, ranging from ending up with code decoration of the relevant semantic elements, in near real-time. that generates compilation errors in the shared repository, to an The novelty of this approach is that it allows software developers evident faulty program behavior, or even worse, an inevident to pinpoint the element in conflict, such as a method’s body, faulty program behavior, that will only be discovered later parameter, return value, and so on, promoting communication on, well after the merge activity and its delicate context are a about conflicting changes soon after they take place and on a semantic level. We have also conducted a preliminary qualitative thing of the past.

  • Automated Testing of Firmware Installation and Update Scenarios for Peripheral Devices
    DEGREE PROJECT IN COMPUTER SCIENCE AND ENGINEERING, SECOND CYCLE, 30 CREDITS STOCKHOLM, SWEDEN 2019 Automated testing of firmware installation and update scenarios for peripheral devices DAG REUTERSKIÖLD KTH ROYAL INSTITUTE OF TECHNOLOGY SCHOOL OF ELECTRICAL ENGINEERING AND COMPUTER SCIENCE Automated testing of firmware installation and update scenarios for peripheral devices DAG REUTERSKIÖLD Master in Computer Science Date: August 12, 2019 Supervisor: Hamid Faragardi Examiner: Elena Troubitsyna School of Electrical Engineering and Computer Science Host company: Tobii AB Swedish title: Automatisering av enhetsinstallation, uppdatering och testning med hjälp av virtuella maskiner iii Abstract This research presents an approach to transition from manual to automated testing of hardware specific firmware. The manual approach for firmware test- ing can be repetitive and time consuming. A significant proportion of the time is spent on cleaning and re-installing operating systems so that old firmware does not interfere with the newer firmware that is being tested. The approach in this research utilizes virtual machines and presents an automation framework. One component of the automation framework is an application to imitate con- nected peripheral devices to bypass hardware dependencies of firmware in- stallers. The framework also consists of automation and pipeline scripts with the objective to execute firmware installers and detect errors and abnormalities in the installation and updating processes. The framework can run on locally hosted virtual machines, but is most applicable using cloud hosted virtual ma- chines, where it is part of a continuous integration that builds, downloads, installs, updates and tests new firmware versions, in a completely automated manner. The framework is evaluated by measuring and comparing execution times with manually conducted installation and updating tests, and the result shows that the framework complete tests much faster than the manual approach.

  • GUI-Guided Test Script Repair for Mobile Apps
    This is the author's version of an article that has been published in this journal. Changes were made to this version by the publisher prior to publication. The final version of record is available at http://dx.doi.org/10.1109/TSE.2020.3007664 1 GUI-Guided Test Script Repair for Mobile Apps Minxue Pan, Tongtong Xu, Yu Pei, Zhong Li, Tian Zhang, Xuandong Li Abstract—Graphical User Interface (GUI) testing is widely used to test mobile apps. As mobile apps are frequently updated and need repeated testing, to reduce the test cost, their test cases are often coded as scripts to enable automated execution using test harnesses/tools. When those mobile apps evolve, many of the test scripts, however, may become broken due to changes made to the app GUIs. While it is desirable that the broken scripts get repaired, doing it manually can be preventively expensive if the number of tests need repairing is large. We propose in this paper a novel approach named METER to repairing broken GUI test scripts automatically when mobile apps evolve. METER leverages computer vision techniques to infer GUI changes between two versions of a mobile app and uses the inferred changes to guide the repair of GUI test scripts. Since METER only relies on screenshots to repair GUI tests, it is applicable to apps targeting open or closed source mobile platforms. In experiments conducted on 22 Android apps and 6 iOS apps, repairs produced by METER helped preserve 63.7% and 38.8% of all the test actions broken by the GUI changes, respectively.

Over the intervening six years, accelerated by the cloud and a growing comfort with outsourcing human activates to machines, software has become ubiquitous. With examples like Amazon displacing traditional retailers or a proprietary “Today's large John Deere tractors have application for player evaluation named “Carmine” helping to lead the Boston Red Sox more lines of code than early space to three titles since 2004, the power of software cannot be understated. shuttles.” Samuel Allen (CEO, Deere & Company) ◼ Software is not only disrupting business models in place for centuries (or 86 years of baseball futility), but it also is enabling incumbent vendors across disparate industries to improve product offerings, drive deeper engagement with customers and optimize selling and marketing efforts.

As Andreessen wrote, “the days when a car aficionado could repair his or her own car are long past, due primarily to the high software “Software is like entropy.
