Model based testing of the Bilihome medical device, an experience report
This paper is about how the Bilihome medical device has been developed, in particular about the modeling and model-based-testing of it. Bilihome makes a wearable Light Therapy device, designed to help newborn babies recover from jaundice. The device consists of several technical components such as the GUI, pads, battery, LEDs, control software etc. Together they enable medical treatments. We show • How to model the components in such a device • How model-based testing gives more coverage than alternative test automation techniques. • How model-based testing works in the regulated medical market. • An experience report of how we applied model-based testing and the issues that we found and solved. We think this paper is also interesting for people outside of the medical market because many of the techniques and lessons learned translate to other embedded/cyber physical devices.
