Iterative Refinement of Reverse-Engineered Models by Model-Based Testing

This paper presents an iterative technique to accurately reverse engineer models of the behaviour of software systems. A he novelty of the approach is the fact that it uses model-based testing to refine the hypothesised model. The process call in principle be entirely automated, and only requires a very small amount of manually generated information to begin with. We have implemented the technique for use in the development of Erlang systems and describe both the methodology as well as our implementation.
