Method for quantitative analysis of comprehensive testing coverage of system structure, functions and performance

The invention discloses a method for quantitative analysis of comprehensive testing coverage of system structures, functions and performance, comprising the following steps: 1, establishing parameters of the structure, functions, performance of the system and testing basic information; 2, establishing direct incidence relation;3, quantitatively calculating testing coverage; and 4, analyzing defects of testing design. The invention realizes quantitative analysis of testing coverage and obtains the tested coverage rate of the performance parameter, functional coverage rate and structural coverage rate by establishing the system structure, functions, performance parameters, testing integration and each direct incidence relation integration among the structure, the functions and the performance parameters and the test.
