Test-Driven Web Application Development: Increasing the Quality of Web Development By Providing Framework with an Emphasis On Test-Driven Design and Development Methodologies

Web applications , especially those based on interpreted programming languages , are quickly becoming more utilized and more commonplace than traditional client applications. Despite this growth, no open solution has yet fulfilled the need of a risk-reducing development framework that supports test-driven methodologies and tools designed to coordinate the resources responsible for the most effective development of web applications based on interpreted programming languages. This research paper presents a test-driven development framework consisting of openly available components that can be used by development teams writing web applications based on interpreted programming languages based on the methodologies and tools used by traditional software development teams using compiled programming languages

An investigation on test driven discrete event simulation

This paper deals with the application of modern software development tools on simulation development. Recently, Agile Software Development (ASD) methods enjoy an increasing popularity. eXtreme Programming (XP) techniques, one of the techniques which belong to the ASD group of methods is a software development method which improves software quality and responsiveness of software projects through introducing short development cycles and a Test Driven Development (TDD) philosophy throughout the development. In this paper, we particularly pay attention to the application of the TDD by approaching simulation development from a test-first perspective. This study consists of a feasibility study of applying the TDD technique in simulation development in its various levels, say, acceptance and unit testing. Moreover, a simulation case study of a surgical ward has been considered, designed and implemented using the AnyLogic simulation toolkit. Our study differs from the mainstream in many ways. It addresses the feasibility of Test-Driven Simulation Development in Visual Interactive Modelling and Simulation (VIMS) environments as well as providing an insight into how the test-first concept can further help with the choice of components and acceptance testing

Taming the interoperability challenges of complex IoT systems

of communication protocols and data formats; hence ensuring diverse devices can interoperate with one another remains a significant challenge. Model-driven development and testing solutions have been proposed as methods to aid software developers achieve interoperability compliance in the face of this increasing complexity. However, current approaches often involve complicated and domain specific models (e.g. web services described by WSDL). In this paper, we explore a lightweight, middleware independent, model-driven development framework to help developers tame the challenges of composing IoT services that interoperate with one another. The framework is based upon two key contributions: i) patterns of interoperability behaviour, and ii) a software framework to monitor and reason about interoperability success or failure. We show using a case-study from the FI-WARE Future Internet Service domain that this interoperability framework can support non-expert developers address interoperability challenges. We also deployed tools built atop the framework and made them available in the XIFI large-scale FI-PPP test environment

Test driven development with Symfony2

With the advance of technologies used in the software development process, the applications become more complex. Classic methodologies of software development are becoming a big hurdle because of their rigidity. As a consequence, agile software development methodologies are becoming more popular. They demand more communication between the customer and the development team. As a result, both parties better understand the application which leads to better customer satisfaction. With short development cycles, agile methodologies require fast production of code. With test driven development, we can assure better quality of code. This thesis focuses on agile methodology Scrum and the use of test driven development principles in Symfony2 framework for the development language PHP. With real life examples we will demonstrate how to use tools for software testing in Syfmony2 framework and advantages we gained using test driven development on our project

Embedded Software V&V using Virtual Platforms for Powertrain applications

International audienceCurrent development trends for automotive products are driven by time to market reduction, cost optimization, and quality improvement. Dual to these business constraints are demands for innovation and safety conformance which impose increasing complexity on embedded systems. To address these challenges impacting software and hardware to improve system dependability, new methodology and tools need to be set-up. The use of representative virtual platforms combining speed and accuracy allows earlier software development, improved system testing, and fault injection analysis, with a high potential for reuse of system IPs (including both hardware and software). In this paper, we will present investigation on new methods and associated results using a simplified virtual platform to test a powertrain application

Kirjallisuuskatsaus testiautomaatiomalleista ketterässä ohjelmistotestauksessa

Test automation is considered to be a crucial part of a modern Agile development team. Agile software testing methods and development practices, such as Test Driven Development (TDD) or Behavior Driven Development (BDD), continuously assure software quality during development time, from project start to finish. Agile software development methods require Agile testing practices for its implementation. Software quality is built-in and delivering functional and stable software continuously is a key business capability. Automated system and acceptance tests are considered as a routine part of the Continuous Integration (CI) and Continuous Delivery (CD) pipeline. The objective of the research was to study, what test automation models, Agile practices and tools are found in Agile test automation literature and what kind of generic Agile test automation model can be synthesized from this literature. The objective was completed by conducting a systematic literature review of test automation models. The initial search included fifty scientific articles, from which ten models were selected for further analysis. The selected articles and their models were modelled using prescriptive modelling. The tools and Agile practices mentioned in the articles were recorded and categorized. Each model was also categorized according to its domain of application. Using the collected data, a synthesized generic model for Agile test automation model was created. Test automation models proved difficult to evaluate as the models were vastly different from each other in their description, depth of detail, utility, environment, scope and domain of application. A generic Agile test automation model would be characterized with agent, activity, artefact and event elements. It would have a functional information perspective and would be formally presented in text and graphic form. Continuous Integration was identified as the most popular Agile development method and Scrum as the most popular Agile management practice. Continuous Integration was also identified as the most popular tool category
