Abstract

The invention relates to a test coverage analysis method, which comprises the following steps of: S1, obtaining each design key point in a spacecraft according to a design plan of the spacecraft; S2,generating a corresponding verification test item according to each design key point; S3, performing correlation analysis on the design plan, the design key points and the verification test project ofthe spacecraft through a software analysis tool, and obtaining a relational expression; S4, generating an analysis table for test coverage based on the relational expression; and S5, outputting the test plan of the spacecraft according to the analysis table. By means of the test coverage analysis method, comprehensiveness, effectiveness and correctness of test coverage analysis are ensured. The invention provides a general method for analyzing the test coverage of the space station by combining the development characteristics of the space station, and the method can be suitable for carrying out the test coverage analysis work on various large spacecrafts.

Description

technical field [0001] The invention relates to an analysis method, in particular to a test coverage analysis method. Background technique [0002] The space station project is the third phase of the manned spaceflight project. With the substantial increase in the scale of the project and the difficulty of development, the functional requirements and index requirements of the overall project (user) for the space station system are also more complex and diverse. In order to ensure the accurate realization of the functional requirements of the overall project (user), it is necessary to carry out a coverage analysis from technical requirements-design-test, that is, the design of the space station system must be verified by a combination of ground physical tests or digital simulations . The traditional test coverage analysis method usually refers to the test plan of the existing model, on this basis, combined with the design characteristics of the new model, adding new test ite...
