Journal Article Presented at International Conference on Software Engineering

Researchers from Zurich University of Applied Sciences and Delft Technology University collaborated on the development of a journal article that was presented as part of the Journal-first track at the 45th International Conference on Software Engineering (ICSE 2023) held on 14-20 May 2023 in Melbourne, Australia.

The paper titled "Single and Multi-objective Test Cases Prioritization for Self-driving Cars in Virtual Environments" investigates test case prioritization techniques to increase the ability to earlier detect SDC regression faults with virtual tests. The approach, called SDC-Prioritizer, prioritizes virtual tests for SDCs according to static features of the roads and is designed to be used within driving scenarios. These features can be collected without running the tests, which means that they do not require past execution results. Two evolutionary approaches are introduced to prioritize the test cases using diversity metrics (black-box heuristics) computed on static features to find trade-offs between executing the less expensive tests and the most diverse test cases earlier. The paper includes an empirical study that that indicates multi-objective meta-heuristics outperform single-objective approaches when prioritizing simulation-based tests for SDCs.
