Web APIs provide a systematic and extensible approach for application-toapplication interaction. Developers using web APIs are forced to accompany the API providers in their software evolution tasks. In order to understand the distress caused by this imposition on web API client developers we perform a semi-structured interview with six such...

The use of dynamic information to aid in software understanding is a common practice nowadays. One of the many approaches concerns the comprehension of execution traces. A major issue in this context is scalability: due to the vast amounts of information, it is a very difficult task to successfully find your way through such traces without...

In the pull-based development model, the integrator has the crucial role of managing and integrating contributions. This work focuses on the role of the integrator and investigates working habits and challenges alike. We set up an exploratory qualitative study involving a large-scale survey involving 749 integrators, to which we add quantitative...

When trying to understand a system that is based on the principles of Service-Oriented Architecture (SOA), it is typically not enough to understand the individual services in the architecture, but also the interactions between the services. In this paper, we present a technique based on dynamic analysis that can be used to obtain insight into...

Agile software development methods such as eXtreme Programming have brought renewed attention to testing during the software development process, both as a quality assurance method and as a form of live documentation. It is for this reason that a software system’s testsuite is an ideal starting point for gaining knowledge about its inner...

Engineering software systems is a multidisciplinary activity, whereby a number of artifacts must be created — and maintained — synchronously. In this paper we investigate whether production code and the accompanying tests co-evolve by exploring a project’s versioning system, code coverage reports and size-metrics. Three open source case studies...

Ajax-enabled web applications are a new breed of highly interactive, highly dynamic web applications. Although Ajax allows developers to create rich web applications, Ajax applications can be difficult to comprehend and thus to maintain. FireDetective aims to facilitate the understanding of Ajax applications. It uses dynamic analysis at both the...

One of the key factors in customer satisfaction is application performance. To be able to guarantee good performance, it is necessary to take appropriate measures before a server overload occurs. While in small systems it is usually possible to predict server overload using a subjective human expert, an automated overload prediction mechanism is...
