Elementary research on software functional testing size estimation for space astronomical optical payload data processing system

摘要

The Science Center of the international corporation misson SVOM adopts an iterative development approach. The development process is divided into developing three systems: the basic system, the core system and the complete system. Current stage is the basic system, where the development of an optical payload data processing system focuses on correctness of basic data path. Therefore, the strategy of the User Acceptant Test is to cover certain critical and typical business scenarios. In order to reasonably estimate software functional testing cost before test implementation and fully use the resource efficiently during testing process, this paper studies the methods of software functional testing size of this system for the User Acceptant Test This paper summarizes existing scale estimation methods in software engineering field, gives a proper understanding to the research goals and the basic requirements, and proposes a new business process testing size estimation method. The method has been verified simply, and needs to be validated concretely in future development process of SVOM Science Center.
