A Method for Improving Test Coverage by Improving Test Cases

With the development of aerospace industry, the complexity of aerospace software is increasing, and the statue of software testing is becoming more and more important. The coverage test is an important method of testing the code logic defects. In order to meet the particularity of embedded aerospace software, this paper proposes a method to improve test coverage by improving test cases, which reducing the number of test cases and improving the efficiency of testing, thereby improving the effectiveness of test coverage. Based on five kinds of optimization types, the full text reduces the number of test cases and removes redundancy in order to improve the efficiency of test cases. While improving the test coverage, the method improves overall test efficiency, finally achieves the expected effect and reduces the cost of software development.
