In today’s complex landscape of embedded software systems, the robust integration testing need is more critical than ever. This bachelor’s thesis project delves into the integration testing of an articulated hauler dumping system for Volvo Construction Equipment (Volvo CE). The study focuses on the architecture, functional and safety requirements and overall performance of the system. The complexity of modern construction machinery, driven by sophisticated Electronic Control Units (ECUs), demands precise coordination and flawless operation. Inaccuracies or failures in integrated ECUs can result in operational inefficiencies, safety risks, and substantial downtime costs. This paper offers valuable insights into a systematic approach designed to tackle these challenges head-on within the domain of articulated hauler dumping systems. Our exploration comprehensiveness employed diverse testing methodologies, encompassing scenario-based, boundary and stress testing, integration testing, and user interaction testing. This multifaceted approach enabled a thorough understanding of the system’s behavior, reliability, and responsiveness. The research aims to clarify the importance of comprehensive integration testing and its role in ensuring optimal performance, safety, and complex embedded systems efficiency. This study is a valuable resource for researchers, engineers, and professionals navigating the complexities of embedded systems integration, offering actionable insights and strategies for achieving robustness and reliability in intricate machinery operations.
