Context: Simulation-based testing is essential when developing Advanced Driver-Assistance Systems (ADASs) and autonomous driving (AD) systems, producing fast, high-quality test results, at relatively low cost. Simulation testing relies on the quality of the ADAS simulation platform: If the simulation platform is faulty, then the simulation results may be incorrect, and hence useless. However, because of the lack of suitable test oracles — mechanisms to determine the correctness of the software output or behavior — it can be too difficult (or expensive) to verify or validate ADAS/AD simulat...

In this paper, we consider the testing of software whose input involves a data stream, such as in video analysis applications. To address the oracle problem in testing this kind of software, existing metamorphic testing (MT) and metamorphic exploration (ME) techniques typically generate both source and follow-up input streams. In contrast, we propose a different strategy: an inplace method. Instead of examining relations among multiple input streams, our method works on a finer granularity by investigating relations among the data frames within a single input stream - such as the relations amo...

Computing systems are becoming increasingly complex and sophisticated. Technologies such as artificial intelligence, big data, and autonomous vehicles are pushing the boundaries of system size, complexity, and comprehensibility beyond anything seen before. These advances, however, have left the associated software quality assurance (SQA) tools and processes behind. This is compounded by many training and education programs also not attempting to address this inadequacy in the preparation of future software engineering professionals. We face a situation of extensively-deployed advanced computin...
