An Integrated Strategy for Testing User-Oriented Software Systems

本研究开发了一种集成策略，用于对大量用户访问的无处不在的软件系统进行有效测试，例如用于支持Internet和万维网（WWW）的软件系统，从用户的角度确保其令人满意的性能和可靠性。这一战略包括三个重要组成部分：1。开发一套高级操作概要（OPs），其中列举了软件要支持的主要功能及其目标用户的使用频率，并按相关用户功能分组组织。对于上面的每个高级功能组，构建了一个基于马尔可夫链的模型，以详尽地测试高级操作，并有选择地测试重要的低级实现，并分析测试结果以确定系统瓶颈，以提高可靠性。上述关键部件的可靠性可以使用传统的测试技术或其他质量保证技术来保证。该研究将涉及工业合作伙伴，包括IBM、北电网络和洛克希德-马丁航空公司，以进行结果验证、软件工具支持和未来部署。

This research develops an integrated strategy for the effectivetesting of ubiquitous software systems accessed by the massive userpopulation, such as those used to support the Internet and World Wide Web (WWW),to ensure their satisfactory performance and reliability from the users'perspective. This strategy includes three important components:1. Development of a set of high-level operational profiles (OPs),which enumerates major functions to be supported by a software and theirusage frequencies by target users, organized in groups of related userfunctions.2. For each high-level function group above, a Markov chain basedmodel is constructed to exhaustively test high-level operations andselectively test important low-level implementations, with the testing resultsanalyzed to identify system bottlenecks for reliability improvement.3. Reliability of the critical parts identified above can be assuredusing traditional testing techniques or other quality assurance techniques. This research will involve industrial partners, including IBM, Nortel Networks, and Lockheed-Martin Aeronautics, for result validation, software tool support, and future deployment.
