Abstract

The invention discloses a test case generation method based on a VRM model, comprising: preprocessing the VRM model, further dividing according to content types, and extracting corresponding test information from the divided content; for each content type , extract the constraint path and the corresponding calculation assignment statement from the extracted test information; analyze the error type according to the constraint path; extract the corresponding test cases according to the two error types of path error and calculation error respectively. The invention can generate test cases starting from the demand model, and effectively makes up for the defect that the software test in the avionics field cannot meet the demand.

Description

technical field [0001] The invention relates to the technical field of model-based software testing, in particular to a method for generating test cases based on a VRM model. Background technique [0002] Avionics systems are typical safety-critical systems with software as the core. According to statistics, more than 80% of the avionics system functions of modern civil aircraft and military aircraft are usually realized through various avionics software, and the coding scale and software complexity are increasing rapidly. Therefore, the development of modern avionics software is a time-consuming process that requires a lot of human and material resources. In the research and development of such software projects, software verification and software testing (V&V) work accounts for about 50%-70% of software development resources. Commonly used software verification techniques include various software analysis, review and testing techniques. Relatively speaking, software tes...
