A Software System Test Method Based on Data Source Identification and Analyzing

Aerospace TT C (Tracking, Telemetry and Command) software system has high security key level, and its quality directly determines the success or failure of the space mission. But due to the large architecture, many software configuration items, the complex internal and external interface, the long data transmission path, the processing of real-time and other factors, its software system testing requirements are high and difficult. However, there are practical problems in system testing that the system testing requirements are not clear and The tests are not highly targeted. Aerospace TT C Center software system is a typical data-driven software system, according to the characteristics of the TT C Center software system, this paper designs a software system test method based on data source Identification and analysis, some key technologies include data source recognition, data flow path analysis, data state analysis and acquisition, system-level data sequential mapping are studied, and the general workflow is introduced. The Method proposed in this paper has been applied in the software system tests of several aerospace TT C centers, and the practices show that the Validity and efficiency of test design can be significantly improved.
