基于面向对象程序代码的类测试技术

面向对象软件的基本测试单元是类，文中提出了用一种基于代码的测试技术－数据流测试来全面地测试类。对类测试分为３级：单个成员函数的测试；公有成员函数的测试；公有成员函数接口的测试。

A Class Testing Technique Based onObject-Oriented Program Code

Class is a basic testing unit of object-oriented software. This paper presents a code-based testing technique(data flow testing) which can widely test classes. Testing class includes three levels: testing a member function; testing a public member functon; and testing an interface between public member functions. Most of exiting data flow testing may test the first two levels. Improved data flow testing can be used to test the third level.It is possible to calculate data flow information through constructing a class control flow graph. Even if there is no specification, this technique can decide the calling order of the member functions being called. We can test class in term of this order. This technique may be automated.
