虚拟测试技术概念辨析

Various Meanings of Virtual Testing

随着“虚拟”一词的广泛使用 ,在计算机辅助测试领域也出现了“虚拟测试”这一概念 ,但不同的作者在使用这一概念时所指的内容其实是大相径庭的。本文对这一新概念进行了整理和归纳 ,将其按性质分为三类 :基于虚拟仪器的虚拟测试技术、基于虚拟现实的虚拟测试技术、基于软件仿真的虚拟测试技术 ,并对每一类技术就其概念、组成、国内外研究现状和发展前景进行了介绍 ,以期对该概念的使用形成比较一致的认识 ,从而对以后相关方面的研究工作有所帮助。

With the wide use of the word 'Virtual', 'Virtual Test' or 'Virtual Testing' also appears in the field of Computer-Aided-Testing(CAT), but the concept bears different meanings for different users. In this paper attempts are made to clarify the different uses by grouping them into three categories: Virtual Testing based on Virtual Instrument, Virtual Testing based on Virtual Reality, and Virtual Testing based on software simulation. The concept, architecture, state-of-the-art and development trend of each category are introduced, aiming to form a relatively common understanding of the concepts, thus facilitating relevant researches.
