Research-Based Innovation (RBI) aims at bringing research-driven innovative solutions to the industrial problems identified from the industry in close collaboration with researchers. This paper focuses on presenting one such instance of RBI between Cisco Systems, Norway and the Software Engineering department of Simula Research Laboratory, Norway over the period of last nine years. The main topic of the collaboration was related to improving the current testing practice at Cisco with the use of models. We present a brief overview of various model-driven testing projects, and lessons learned from such RBI collaboration.
