An approach for optimizing of the aerospace software regression test cases

Owing to complex development phases and frequent requirement changes of the aerospace software, the workload of the regression test is more than half of the total amount of software test. And aerospace software requires high reliability, so each revision of the test requirements must be covered in the process of the regression testing. Therefore in the process of the aerospace software regression test it is an urgent problem be solved that how to complete the full coverage of the changes under the less manpower cost. In this paper, an approach for optimizing of the aerospace software regression test cases is proposed, which can save more test resources and ensure the coverage of the changed contents.
