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

Abstract

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.

Description

technical field [0001] The present invention relates to a test coverage quantitative analysis method integrating system structure, function and performance, which belongs to the technical field of testing. Background technique [0002] Testability is an important design characteristic of systems and devices that facilitates testing and diagnosis. Systems and equipment with good testability can detect and isolate faults in a timely and rapid manner, improve the reliability and safety of task execution, shorten the time for fault detection and isolation, thereby reducing maintenance time, improving system availability, and reducing system usage guarantee costs . [0003] In the traditional testability, the fault of the system is used as the object of testing, and the fault detection rate and fault isolation rate are used to measure and evaluate the test coverage ability of various types of tests for system faults. In engineering practice, the analysis and improvement of faul...

Problems solved by technology

In engineering practice, the analysis and improvement of fault test coverage is very inconvenient, which is mainly reflected in two aspects. The first is that the analysis and processing of faults requires complex reliability expertise and work to support; the second It is the engineering designers who directly face the performance parameters, functions, and structures of the system, rather than the faults, when designing the system. Since there is no direct correlation between the two, the engineering designers cannot intuitively check the coverage of the fault test. Knowing the design flaws of the test in terms of system performance parameters, functions or structural coverage, it is not easy to carry out corresponding improvement work

[0004] According to the test configuration of the system, directly analyze the coverage degree of the system structure, function and performance parameters, which plays an important role in quantitatively evaluating the test coverage ability and discovering test design defects, but there is no corresponding quantitative analysis method and tool support.
