For the problems of airborne flight control management software test such as depending on hardware system,long test cycle,low efficiency of manual test,poor reuse,error-prone and high maintenance cost,the key technologies of full digital simulation environment is researched,an automatic test method for airbone flight control management software is presented. This test method based on the full digital simulation environment,improved traditional test data generation algorithm,uses the AETG-SA algorithm to generate test data,introduced feedback from test results into the algorithm and dynamically adjust algorithm parameters,obtain the optimal test set,and improves test coverage. Executing test cases in full digital simulation environment reduces the hardware dependency of embedded software testing process,and higher coverage of system function test and fault simulation test,and improves the effiiciency of test cases greatly. Compared with the traditional full-physical and semi-physical test methods,the engineering practice shows that the automated test method based on the full digital simulation environment improves 4% in sufficiency and 44% reduction in testing time.
