Coverage analysis of airborne software testing based on DO-178B standard

Software testing is one of the most important ways to protect and enhance civil aviation safety and reliability of software on airborne equipment. Among software testing, test coverage analysis is absolutely necessary. Therefore, based on DO-178B standard, this paper studies the method of software texting coverage analysis. With the example of TCAS software texting established in the test environment of hardware and the testing tools of software, we complete the software test coverage analysis
