Realization of Coverage Testing for Aeroplane Central Maintenance System Based on LDRA Testbed

Based on the testing tool LDRA Testbed,this paper realizes the coverage testing work of Plane Central Maintenance System.By means of the menu source of Plane Central Maintenance System as the sample,the paper shows that the testing tool can be successfully used in Plane Central Maintenance System through the testing process,and reaches the stated testing rate of Statement Coverage Analysis and Branch Coverage Analysis.At the end of the paper,there is the testing process and result of system software.According to the testing result,to use the LDRA Testbed tool can greatly improve the software testing efficiency of Plane Central Maintenance System.At the same time,it can meet the aerial software standard-DO-178B,and gain the stated testing rate of Statement Coverage Analysis and Branch Coverage Analysis.
