— Model-driven engineering (MDE) techniques are increasingly being used to address many of the development and operational lifecycle concerns of large-scale component-based systems. One such concern that is growing in importance, but lacking significant research is the validation of quality-of-service (QoS) properties of component-based systems throughout their development lifecycle. In the current state of the art, large-scale component-based systems have to wait until system integration time to perform in-depth QoS testing, which can be too late and detrimental to project schedules and costs. This paper describes our novel MDE-based solution to address this challenge. At the core of our solution approach are (1) a set of domainspecific modeling languages that allow us to mimic component “business logic,” and (2) a generative programming framework that synthesizes configuration files for system simulation. A particular thrust of this paper is describing the syntax and semant...
