Formal Specs Verifier ATG: a Tool for Model-based Generation of High Coverage Test Suites
Résumé
In this paper we describe Formal Specs Verifier Automatic Test Generation, a tool generating high coverage test suites for embedded systems. Our tool implements a test case synthesis algorithm using a combination of model checking and optimization techniques starting from a Simulink/Stateflow model of the System Under Test. The main contributions of this paper are the following: we (1) give an extended description of our test generation algorithm, (2) describe the algorithm implementation as part of the Formal Specs Verifier framework, (3) present a concrete application of the tool to a cruise control case study and discuss experimental results comparing our algorithm with a state-of-the art COTS tool.
