Sammanfattning
Mechanical products are increasingly evolving into software-driven systems with expanded responsibilities, as exemplified by the rapid advancements in the vehicle
industry and the rise of autonomous driving technologies. Cyber-physical systems
(CPSs), such as vehicles that rely on both hardware and software, present significant
testing challenges due to their distributed nature and the necessity for real sensor
input data. Traditional testing methodologies are suboptimal for CPS, as they typically do not accommodate the integration of both simulation and hardware testing
in a distributed environment. This thesis aims to evaluate the feasibility and effectiveness of a containerized, microservice-based testing framework. The framework is
designed to support simulation, data replay and hardware test levels and to be integrated into a continuous integration and continuous deployment (CI/CD) pipeline.
The proposed framework was implemented and tested within the context of the
TME290 Autonomous robots course at Chalmers University of Technology. This
involved the development of hardware-in-the-loop (HIL) rigs, as well as the creation
of test execution and interpretation software. The framework’s capabilities were assessed through the execution of various test scenarios. The integration of the testing
framework into the course demonstrated its suitability for simulation, data replay,
and hardware test levels on a distributed system. Furthermore, it was successfully
integrated into a CI/CD pipeline. The findings suggest that a microservice-based
architecture can effectively be used for the integration testing of CPS within a continuous integration environment. This approach enhances the reliability and efficiency
of testing processes for autonomous systems, offering a promising solution to the
challenges associated with traditional CPS testing methods.
