Extending Behaviour-Driven Development of Avionic Systems to Flight Simulators

Abstract

The role of avionics is crucial for several aircraft functions, from communication to collision avoidance. Amongst others, modern air transportation is the result of the continuous improvement in avionics technology. One of the recent trends in avionics software engineering is streamlining the process with practices that remove the disconnects between the activities to achieve a cost-eff ective and agile engineering life cycle, allowing to cope with the volatile requirements found in emerging segments such as Advanced Air Mobility. Behaviour-Driven Development (BDD) is one of these practices; it connects requirements to (acceptance-) testing. There are already eff orts in adapting BDD for avionic systems. This paper proposes extending BDD of avionic systems to fl ight simulation. It presents an approach for using the requirement specifi cation language of BDD, Gherkin, for setting up the test scenarios and the test framework of BDD, Cucumber, as a test oracle.
