About Reactis

The Reactis tool suite enables users to deploy model-based software testing to dramatically reduce the costs of testing embedded control software. Reactis Tester generates thorough yet compact test suites from models of software given in The MathWorks, Inc.'s market-leading Simulink® / Stateflow® notations. The test suites exercise large portions of the software under test while avoiding redundancy, thereby maximizing the probability of finding defects within the time available for testing. The generated tests store model-generated outputs as well as inputs so that Tester-generated test harnesses can automatically check the correctness of source code implementations of models. Reactis Simulator enables users to visualize the results of executing tests produced by Reactis Tester. The tool also enables users to fine-tune Tester-generated test suites. Reactis runs on the Microsoft Windows and Linux platforms. Reactis is priced at US $5000 per year per concurrent license. Free 30-day evaluation licenses are available.
