ICST Tool Competition 2026 - SDC Testing Track

Abstract

This paper reports on the ICST 2026 edition of the tool competition on regression testing of self-driving cars (SDCs). The competition aims to foster research on test prioritization for simulation-based SDC testing, a rapidly growing and practically relevant domain, by providing a common platform for the submission and evaluation of testing tools.

To facilitate participation, the competition supplies an advanced infrastructure together with representative case studies, enabling participants to develop and assess test generation, selection, and prioritization approaches for SDCs. In its second edition, the competition features four submitted tools, evaluated using regression metrics for test prioritization and compared with baseline approaches, namely a random strategy, and the tools included in the SBFT edition of the same challenge. The paper presents an overview of the competition, including its motivation, framework, evaluation process, participating tools, and key findings.
