Abstract

The invention provides a program change influence analysis method based on a code text and a calling relationship, which belongs to the field of software engineering and comprises the following steps:1, acquiring a method calling relationship of each method through third-party software; step 2, analyzing method text similarity of the initial change set and other method sets from the perspective of the code text; 3, analyzing the method call correlation of the initial change set and other method sets from the perspective of the method call relationship; and 4, calculating a comprehensive method dependence degree according to the method text similarity and the method calling correlation between the initial change set obtained in the step 2 and the method text similarity and the method calling correlation between the initial change set obtained in the step 3 and each method set, thereby obtaining a predicted affected method set. Compared with an existing word differentiation technology for experiment, the method provided by the invention has certain advantages in accuracy.

Description

technical field [0001] The invention belongs to the field of program change impact analysis and relates to a program change impact analysis method based on code text and calling relationship. Background technique [0002] In today's society, computer technology is developing rapidly, covering all fields of society, and has had a profound impact on people's lives. Also getting higher and higher. However, although other innovations such as software technology and development model have a certain effect on improving the efficiency and performance of software development and maintenance, as the scale of software continues to increase and business requirements become more complex, software maintainability decreases and maintenance costs gradually increase. High, causing a great burden to software developers and software users. [0003] Software change impact analysis (Change Impact Analysis, CIA) is a technology often used in software development and maintenance phases. In a h...
