Research On Technology Of Avionics Software Test Planning

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.
