面向对象软件的修改影响分析研究

Research of Analysis Impact Change to Object-oriented Software

在软件维护阶段,修改后的程序应该被重新测试,保证修改能满足用户需求,并且软件能正常运行。但面向对象程序中一个小的修改能产生很大影响,这为测试增加了困难。为了节省测试成本,应只测试修改及修改所影响的部分。提出了一种鉴别修改所影响的部件的方法。

During software maintenance, in order to ensure that the modified software still satisfies user's requirement, and executes correctly, modified programs are required to be retested. But small changes can have major effects in object-oriented programs, this make it difficult to test the modified programs. To save efforts,retesting should be done on only the parts that might be affected by changes. a kind of method which identifies that affected parts by changes is proposed.
