【摘要】 对于航天型号软件测试来说,量化测试过程、改进测试管理水平、提高测试自动化程度是保证测试质量进而保证产品质量和可靠性的重要途径。测试计划是测试过程的指导方针,测试计划水平对测试过程质量起着决定性的作用。本文从航天型号软件的特点入手,重点研究航天型号软件测试计划技术;在参考现有成熟度量技术的基础上,提出了适合我国航天型号软件的单元测试度量模型、集成测试度量模型以及系统测试度量模型;并且在这些模型的基础上,提出了测试工作量估计模型TEEM(Test Effort Estimation Model),并利用最小二乘原理进行参数估计。另外,我们还开发了单元测试度量原型工具、集成测试度量原型工具和测试计划编制原型工具。本课题的研究成果主要体现在创造性的提出了用于航天型号软件测试的软件度量理论以及软件工作量估计模型。本文通过对已有的软件度量和工作量估计模型进行选取和改进扩展,从而提出专门针对测试(特别是航天型号软件测试)的度量和工作量估计模型,并为后续研究提供了研究思路和参考依据。本课题研究成果可供我国航天型号软件研制和测试组织用来进行测试计划安排以及测试过程控制。

【Abstract】 In order to improve the quality and maturity of avionics software test ,we must measure software test processes, increase software test management and introduce more available software test automation tools .In this paper ,we study the technology and methodology of avionics software test planning, which is indispensable to improving the quality of avionics software test and thus to improving the quality of avionics software itself.The key problem is : How to make a software test plan? Or ,What should be taken as the real foundation to make a software test plan? This paper solves this problem by developing a software Test Effort Estimation Model(TEEM) which is based on three software test metric models - unit test metric model ,integration test metric model and system test metric model. These metric models are more accurate and more particular than other existing metric models using KLOC or FPs. The parameters of TEEM have been estimated by the method of least squares .In addition ,we develop a productivity factor model which reflects the productivity of a software test organization and can be used to adjust test efforts calculated by TEEM.In order to apply and validate those models given by this paper, We developed unit test metric tool, integration test metric tool and software test plan making tool, whose introduction and implementation are shown in the last of this paper.
