Construction method of software defect evaluation model on the basis of complex network

Abstract

The invention provides a construction method of a software defect evaluation model on the basis of a complex network, and can predict potential defects in a software system. The construction method comprises the following steps: 1) taking classes in software as nodes and a relationship between the nodes as edges to construct the directed network model of the software; 2) according to the directed network model obtained in 1), carrying out the characteristic measurement calculation of the complex network; 3) scanning a software source code to carry out structured program measurement, and obtaining the measurement values of cyclomatic complexity and function depth; 4) scanning the software source code to carry out object-oriented software measurement; 5) utilizing a FindBugs static analysis tool and a software defect report on an open-source tool official website to search and analyze software defect information; and 6) constructing a defect evaluation formula: using the calculation data of a corresponding effective measurement index for different classes of software, establishing a corresponding multiple linear regression model, and obtaining the software defect evaluation model.

Description

technical field [0001] The invention belongs to the technical field of software network, and relates to a method for constructing a software defect evaluation model based on a complex network. Background technique [0002] Software Defect: A problem, bug, or hidden functional defect in computer software or a program that impairs its ability to function properly. The existence of defects will cause the software product to be unable to meet the needs of users to some extent. IEEE729-1983 has a standard definition of defects: From the internal point of view of the product, a defect is a variety of problems such as errors and defects in the process of software product development or maintenance; from the external point of view of the product, a defect is a certain function that the system needs to achieve failure or violation. [0003] Complex networks: networks with some or all of the properties of self-organization, self-similarity, attractors, small-world, and scale-free. ...

The object-oriented measurement method only focuses on statistics related to the quantity (scale) of object classes. Although it pays attention to the coupling between object classes, it is also a kind of quantitative statistics and cannot reflect the interaction between classes.

These measurement methods focus too much on fine-grained statistics, but do not pay attention to the measurement of coarse-grained module components, etc., and lack global and overall complexity measurement
