Data flow testing (DFT) focuses on the flow of data through a program. Despite its higher fault-detection ability over other structural testing techniques, practical DFT remains a significant challenge. This paper tackles this challenge by introducing a hybrid DFT framework: (1) The core of our framework is based on dynamic symbolic execution (DSE), enhanced with a novel guided path search to improve...
Recently code transformations or tailored fitness functions are adopted to achieve coverage (structural or logical criterion) driven testing to ensure software reliability. However, some internal threats like negative impacts on underlying search strategies or local maximum exist. So we propose a dynamic symbolic execution (DSE) based framework combined with a path filtering algorithm and a new heuristic...
AUTOSAR, derived from OSEK/VDX, is the most popular industrial standard in the automotive electric development. It is challenging to manually verify or validate the correctness and safety of AUTOSAR Operating System (OS) as well as mission-critical or real-time applications built on it. In this paper, we adopt timed CSP to describe and reason about the Schedule Table, a new task scheduling mechanism...
