Abstract

The invention provides a software reliability measurement method based on software network structure characteristics, and belongs to the technical field of software complex networks. The method comprises the steps that firstly, a complete software source code of target software is acquired, a software network is constructed, importance calculation is conducted on modules in the software network, and important modules are recognized; Secondly, calculating the structure complexity, the code complexity, the interface complexity and the change frequency of each important module, and further calculating the structure reliability risk, the code reliability risk, the interface reliability risk and the change reliability risk of the software; And finally, the software reliability is measured by integrating the risks in four aspects, and the higher the calculated software reliability value is, the higher the software reliability risk is. According to the method, time-consuming and labor-consuming reliability testing is not needed, software reliability testing is not needed, time and manpower resources are saved, the problem that reliability of an existing software module is difficult to evaluate is solved, and the specific position of a high-risk module can be positioned.

Description

technical field [0001] The invention belongs to the field of complex software networks, and relates to a method for measuring software reliability based on the structural characteristics of software networks. Background technique [0002] With the rapid development of network and information technology in recent decades, software, as a carrier for computers to realize various functions and assist people in various activities, plays an important role in all walks of life in the world today. An efficient and safe software system is highly dependent on software quality. Therefore, it is particularly important to have a clear understanding of software quality and reliability before the software is put into use. [0003] The traditional software reliability evaluation method is similar to hardware reliability evaluation: 1) According to the actual usage of the user, construct the operation profile to generate test cases; 2) Use the generated test cases to perform software testing...
