Bridging test and model-driven approaches in web engineering

In the last years there has been a growing interest in agile methods and their integration into the so called "unified" approaches. In the field of Web Engineering, agile approaches such as test-driven development are appealing because of the very nature of Web applications, while model-driven approaches provide a less error-prone code derivation; however the integration of both approaches is not easy. In this paper, we present a method-independent approach to combine the agile, iterative and incremental style of test-driven development with the more formal, transformation-based model-driven Web engineering approaches. We focus not only in the development process but also in the evolution of the application, and show how tests can be transformed together with model refactoring. As a proof of concept we show an illustrative example using WebRatio, the WebML design tool.Publicado en Lecture Notes in Computer Science book series (LNCS, vol. 5648).Laboratorio de Investigación y Formación en Informática Avanzad

Agile managing of web requirements with WebSpec

Web application development is a complex and time consuming process that involves di erent stakeholders (ranging from customers to developers); these applications have some unique characteristics like navigational access to information, sophisticated interaction features, etc. However, there have been few proposals to represent those requirements that are speci c to Web applications. Consequently, validation of requirements (e.g. in acceptance tests) is usually informal, and as a result troublesome. To overcome these problems, this PhD Thesis proposes WebSpec, a domain speci c language for specifying the most relevant and characteristic requirements of Web applications: those involving interaction and navigation. We describe WebSpec diagrams, discussing their abstraction and expressive power. As part of this work, we have created a test driven model based approach called WebTDD that gives a good framework for the language. Using the language with this approach we have test several of its features such as automatic test generation, management of changes in requirements, and improving the understanding of the diagrams through application simulation. This PhD Thesis is composed of a set of published and submitted papers. In order to write this PhD Thesis as a collection of papers, several requirements must be taken into account as stated by the University of Alicante. With regard to the content of the PhD Thesis, it must speci cally include a summary which is devoted to the description of initial hypotheses, research objectives, and the collection of publications itself, thus justifying its coherence. It should be underlined that this summary of the PhD Thesis must also include research results and nal conclusions. This summary corresponds to part I of this PhD Thesis (chapter 1 has been written in Spanish while chapter 2 is in English).

Test-Driven Web Application Development in Java

Today, software availability as well as adaptability has a strong impact on application development. Together with the success of the Internet technology, it is often necessary to offer a web-based software solution. For Java development, J2EE builds a bridge from traditional towards web application development. Java Server Pages and Servlets allow the implementation of web sites with dynamic content. Anyway, it is still possible to apply well-tried programming paradigms, e.g. the Model-View-Controller (MVC) paradigm
