Abstract: In the large-scale project of software white-box testing，it increases lots of additional difficulties for testing work in that source codes variety frequently，it is an important work for white-box testing process management to control and manage source codes effectively.It researches actuality of version control and management based on existing software testing process model and presents a new method of version contrast，it applies an abstract method，a simplified directory tree，to contrast software modules.It decomposes granularity to method for file contrast，and it researches the contrast algorithm within a method.At last it designs and implements a subsystem of version management for source codes in actual project.

Key words: white-box testing, testing process management, source code analysis, source code variation, version control

摘要： 在大型软件白盒测试项目中，源代码的频繁变化给测试工作增加了很大难度，对源代码进行管理和控制是对白盒测试过程管理的一个重要补充。在已有的软件测试过程管理模型基础上，认真分析研究版本控制和管理的相关技术现状，提出了变更管理的改进方法，对于软件模块的比较采用了抽象的方法简化为目录树，而在文件比较中基于源代码静态分析工具，把文件比较的粒度分解到方法一级，进行了方法内部比较算法的研究，设计实现了源代码版本管理子系统。
