Search-Based Selection and Prioritization of Test Scenarios for Autonomous Driving Systems
2021
Violating the safety of autonomous driving systems (ADSs) could lead to fatal accidents. ADSs are complex, constantly-evolving and software-intensive systems. Testing an individual ADS is challenging and expensive on its own, and consequently testing its multiple versions (due to evolution) becomes much more costly. Thus, it is needed to develop approaches for selecting and prioritizing tests for newer versions of ADSs based on historical test execution data of their previous versions. To this end, we propose a multi-objective search-based approach for Selection and Prioritization of tEst sCenarios for auTonomous dRiving systEms (SPECTRE) to test newer versions of an ADS based on four optimization objectives, e.g., demand of a test scenario put on an ADS. We experimented with five commonly used multi-objective evolutionary algorithms and used a repository of 60,000 test scenarios. Among all the algorithms, IBEA achieved the best performance for solving all the optimization problems of varying complexity.
