Software complex network-based four-dimensional software evolution measurement analysis method

Abstract

The invention discloses a software complex network-based four-dimensional software evolution measurement analysis method, and belongs to the field of software engineering. The method comprises the steps of performing function call network extraction on a code of each version of target software; performing measurement monitoring on four dimensions of modularity, structure hierarchy, complexity and fault propagation of software in a version evolution process, wherein three basic measurement indexes are set for each dimension; performing statistics on dimension measurement results, and drawing fluctuation trend graphs of version evolution; evaluating the version of the target software in combination with a four-dimensional measurement reference threshold of a target software type; and putting the software with relatively good evaluation results into a software reference library, and performing reference threshold optimization. According to the method, comprehensive monitoring of overall structure quality level of a software product is realized; problems existent in software development can be corrected in time; and the target software of the same type is analyzed and evaluated under unified reference threshold standards, so that the objectivity and validity of the results are ensured.

Description

technical field [0001] The invention is applied in the field of software engineering, and is an analysis method based on software complex network measurement for evaluating the software quality level in the process of software development and maintenance. Background technique [0002] With the increasing popularity and in-depth application of software in people's lives, people's requirements for software functions are becoming more and more abundant, and their requirements for software quality are getting higher and higher. The expansion of software scale and the increasingly complex software application environment make the scale and complexity of software systems continue to grow. This not only brings more software problems but also makes the software system more difficult to control. In order to better solve software problems, develop and maintain software, it is necessary to have a more comprehensive and in-depth understanding of software characteristics. Therefore, fr...

Problems solved by technology

[0005] The present invention aims at the problem that the current software measurement and analysis method is limited to a single or limited aspect of software structure characteristics, which leads to incomplete analysis of software products, and proposes a four-dimensional software evolution analysis method based on software complex network measurement method. Four structural characteristics (MHCP for short) of the software in the process are measured and monitored: Modularity, Hierarchy, Complexity and Propagation
