Continuous Integration Testing of Embedded Software with Digital Twin Prototypes

Abstract

Digital Twins may be employed for developing embedded software and can be classified in three subcategories by their level of integration with the corresponding physical objects/twins. We introduce and report on experience with a new category: the Digital Twin Prototype. Digital Twin Prototypes support engineers to test embedded software systems, without the need of a connection to a physical object. In CI/CD pipelines they can be used for integration testing and thus, allow for an agile verification and validation process. We developed and evaluated this approach to create an underwater network of ocean observation systems. The feasibility was shown in a demonstration mission in the Baltic Sea in October 2020.

Continuous Integration Testing of Embedded Software with Digital Twin Prototypes

“…A proof of concept for the formal specifications was demonstrated in a demonstration mission showcasing the viability of digital twins in ocean observation systems [43]. Moreover, we offered insight into how this approach could be employed in the SilageControl smart farming project, which aims to enhance the silagemaking process through the development of a sensing platform [46].…”

“…Thereby, data gathered by the digital twin improves the digital twin/digital twin prototype and vice versa. A case study with more details about this project was published by Barbie, Hasselbring, and Hansen [46].…”
