In the same way that natural languages influence and shape the way we think, program- ming languages have a profound impact on the way a programmer analyzes a problem and formu- lates its solution in the form of a program. To the extent that a first programming course is likely to determine the student’s approach to program design, program analysis, and programming meth- odology, the choice of the programming language used in the first programming course is likely to be very important. In this paper, we report on a recent survey we conducted on programming language use in US academic institutions, and discuss the significance of our data by comparison with programming language use in industry. Keywords: programming language use, academic institution, academic trends, programming lan- guage evolution, programming language adoption. 1. Introduction: Programming Language Adoption The process by which organizations and individuals adopt technology trends is complex, as it involves many diverse factors; it is also paradoxical and counter-intuitive, hence difficult to model (Clements, 2006; Warren, 2006; John C, 2006; Leo and Rabkin, 2013; Geoffrey, 2002; Geoffrey, 2002a; Yi, Li and Mili, 2007; Stephen, 2006). This general observation applies to programming languages in particular, where many carefully de- signed languages that have superior technical attributes fail to be widely adopted, while languages that start with modest ambitions and limited scope go on to be widely used in industry and in academia.

  • Model-Based Testing in Practice: an Experience Report from the Web Applications Domain
    Model-based testing in practice: An experience report from the web applications domain Vahid Garousi Alper Buğra Keleş, Yunus Balaman, Andrea Arcuri Queen’s University Belfast, UK Zeynep Özdemir Güler Kristiania University College, Norway Bahar Software Engineering Consulting Testinium A.Ş., Istanbul, Turkey Oslo Metropolitan University, Norway Corporation, UK {alper.keles, yunus.balaman, [email protected] [email protected] zeynep.ozdemir}@ testinium.com Abstract: In the context of a software testing company, we have deployed the model-based testing (MBT) approach to take the company’s test automation practices to higher levels of maturity and capability. We have chosen, from a set of open-source/commercial MBT tools, an open-source tool named GraphWalker, and have pragmatically used MBT for end-to-end test automation of several large web and mobile applications under test. The MBT approach has provided, so far in our project, various tangible and intangible benefits in terms of improved test coverage (number of paths tested), improved test-design practices, and also improved real-fault detection effectiveness. The goal of this experience report (applied research report), done based on “action research”, is to share our experience of applying and evaluating MBT as a software technology (technique and tool) in a real industrial setting. We aim at contributing to the body of empirical evidence in industrial application of MBT by sharing our industry-academia project on applying MBT in practice, the insights that we have gained, and the challenges and questions that we have faced and tackled so far. We discuss an overview of the industrial setting, provide motivation, explain the events leading to the outcomes, discuss the challenges faced, summarize the outcomes, and conclude with lessons learned, take-away messages, and practical advices based on the described experience.

  • Dispelling Inertia Towards Behavior-Driven Development an Assessment Tool for Development Practice Readiness
    DEGREE PROJECT IN TECHNOLOGY, FIRST CYCLE, 15 CREDITS STOCKHOLM, SWEDEN 2019 Dispelling inertia towards behavior-driven development An assessment tool for development practice readiness AGNES PETÄJÄVAARA KTH ROYAL INSTITUTE OF TECHNOLOGY SCHOOL OF ELECTRICAL ENGINEERING AND COMPUTER SCIENCE Abstract Behavior-driven development (BDD) is a development practice focusing on behaviors and requirements from users and stakeholders. It is designed to develop behaviors which contribute directly to system outcomes. BDD encourages multiple stakeholders to collaborate by minimizing communication gaps and create a shared understanding of the project between technical and non-technical speakers. As a result, the development process becomes faster and the cost lower. Although BDD has many benefits, there are teams who feel inertia towards using it as their main development practice. This thesis work took place at a company with a strong agile foundation. It had the goal to investigate reasons why teams feel inertia against BDD, and thus contribute to BDD research and assist the company. The assumption that positive motivation would help in dispelling inertia was the idea behind this thesis work, and that a stronger motivation for a practice can be achieved by assessing a team’s suitability for it. To reach the goal of the thesis a qualitative research methodology was used, with a focus on obtaining a better understanding of opinions and behaviors that exist, with rounds of interviews and forms as the main method of data collection. Interviews were also consistently used throughout the thesis work to validate that it followed the right track. The inertia which teams at the company have experienced was clustered into different dimensions.

  • Assessment of Programming Language Reliability Utilizing Soft-Computing
    International Journal on Computational Sciences & Applications (IJCSA) Vol.3, No.3, June 2013 Assessment of Programming Language Reliability Utilizing Soft-Computing 1Obi J.C. and 2Akwukuma V.V.N. 1,2Department of Computer Science. University of Benin, P.M.B. 1154. Benin City. Nigeria. 2e-mail: [email protected]; +234(0)8033440003; Corresponding author: 1e-mail: [email protected]; +234(0)8093088218 Abstract Reliability is a critical program evaluation criterion so much so that program writing (expressing one’s computational ideas) will be of no use if the end result is not consistent. Programmers cognizant pertaining to a particular programming language selected for solving a particular computational problem will yield the desired result. This can only be achieved if the program written in a particular programming language either structured (C, C++) or Objected-Oriented (Java, C#, Ruby) is gauge with the criteria’s for evaluating program reliability. Adopting a soft-computing based approach will help model solutions to program reliability utilizing linguistic variables. Simulating a soft-computing system comprising of genetic algorithm and fuzzy logic for determining program language reliability was the rationale behind this research paper. The reliability of programming language could be determined in terms of “Reliable”, “Moderate Reliable” and “Not Reliable” based on the possessed reliability criteria of the examined programming language. Keywords Fuzzy logic, Fuzzy set, Reliability, Soft-computing. 1.0 Introduction Reliability is an essential program attribute. Reliability is closely linked with the quality of measurement which is determined by the "consistency" or "repeatability" of program measure (Jiantao, 1999). Program reliability is the probability of failure-free program operation for a specified period of time under a specified set of conditions or defined as producing expected results for all correct input or the ability of a program to perform to specification under all conditions (Robert, 2006).

  • Model-Based Testing: from Requirements to Tests
    FACULDADE DE ENGENHARIA DA UNIVERSIDADE DO PORTO Model-based testing: From requirements to tests Daniel Ademar Magalhães Maciel Mestrado Integrado em Engenharia Informática e Computação Supervisor: Professor Ana Cristina Ramada Paiva Second Supervisor: Professor Alberto Manuel Rodrigues da Silva February 21, 2019 Model-based testing: From requirements to tests Daniel Ademar Magalhães Maciel Mestrado Integrado em Engenharia Informática e Computação February 21, 2019 Abstract Software testing is increasingly valued as it promotes the quality of the software by checking that it meets the expected requirements. Frequently, software testing tends to be neglected at the beginning of the projects, only performed on the late stage. However, it is possible to benefit from combining testing with requirement specification activities. On one hand, acceptance tests specification will require less manual effort since they are de- fined or generated automatically from the requirements specification. On the other hand, the re- quirements specification itself will end up having higher quality due to the use of a more struc- tured language, reducing typical problems such as ambiguity, inconsistency and incorrectness of requirements. In this research we propose an approach that promotes the practice of tests specification since the very beginning of projects, and its integration with the requirements specification itself. This approach is conducted by model-driven techniques that contribute to maintain the requirements and tests alignment, namely alignment between requirements (defined as use cases), test cases, and low-level automated test scripts. To show the applicability of this approach we integrate two complementary languages: (i) the RSL (Requirements Specification Language) that is particularly designed to support both require- ments and tests specification in a rigorous and consistent way; and (ii) the Robot language, which is a low-level keyword-based language for the specification of test scripts.
