Abstract

The success of Web applications is constrained by two key features: fast evolution and usability. Current Web engineering approaches follow a "unified" development style which tends to be unsuitable for applications that need to evolve fast. Moreover, according to the quality standard ISO 9126-1, usability is a key factor to obtain quality systems. In this paper, we show how to address usability requirements in a test-driven and model-based Web engineering approach. More specifically, we focus on usability requirements with functional implications, which do not only concern the visual appearance, but also the architecture design. Usability requirements are contemplated from the very beginning of each cycle, by creating a set of meaningful tests that drive the development of the application and ensure that no functionality related to usability is altered unintentionally through development cycles. Dealing with those usability requirements in the very early steps of the software development process avoids future hard changes in the system architecture to support them. The approach is illustrated with an example in the context of the OOWS suite.
