Learn and Test for Event-B - a Rodin Plugin

Abstract

The Event-B method is a formal approach for reliable systems specification and verification, being supported by the Rodin platform, which includes mature plugins for theorem-proving, model-checking, or model (de)composition features. In order to complement these techniques with test generation and state model inference from Event-B models, we developed a new feature as a Rodin plugin. Our plugin implements a model-learning approach to iteratively construct an approximate automaton model together with an associated test suite. Test suite optimization is further applied according to different optimization criteria.
