Abstract

The application provides a use scenario and knowledge base driven fault mode identification and analysis method, which can effectively identify complex fault modes and robust test case design without omission. The robust test design based on the use scenario needs to research the technical methods such as use scenario construction, use scenario based basic software FMEA analysis criterion, use scenario and knowledge base driven software FMEA analysis process, realizes the description of abnormal test scenarios such as error data processing, abnormal situation processing and illegal operation processing, simultaneously describes the combination test scenario based on the software use profile, simultaneously performs the robust test case design covering the fault modes based on the FMEA analysis result, and supports the software development and test personnel to carry out the software FMEA analysis, robust requirement acquisition and other work in the development process.
