Since starting my work career in the telecommunications industry more than 20 years ago, I have been looking for ways to apply tool supported development techniques. At a time when the need for professional software testing was gathering recognition and testers were not participating in development teams, I was correcting software errors in database systems. This experience guided my understanding of how important systematic software development is in preventing errors. My journey has been driven by the curiosity of what improvements new software development techniques can provide to the end product quality. This work presents a novel approach to Aspect-Oriented Modelling and testing to address the needs of Model-Based Testing. The approach aims at providing assistance for incremental test model creation as well as for abstract test purpose specification by referring to attributes of aspects. This methodology results in three advantages: testability of system under test quality attributes, a simple rule for composition, and better comprehension of test models. The usability of the method is demonstrated on the Home Rehabilitation System testing case-study.
