COM在测试软件设计中的应用

Application of COM Technology in Course of Designing Test Software

COM规范包括COM对象、COM接口和IUnknown接口。COM库是COM的实现部分,并连接组件程序和客户程序。COM库通过系统注册表提供的信息创建对象。利用COM组件技术进行测试系统软件开发,实现了系统的模块化、标准化和重用性。可以缩短开发周期,提高开发效率,降低软件的维护费用。

COM standard includes COM object, COM interface and IUnknown interface. COM base is one of the realization parts of COM; it was also used to connect component program and user program. By using the information provided by system register list, COM base established objects. The COM component technology was adopted to carry out the software development of test system, and realize the modularization design, standardization design and reuse design of system. It was also used to short the development cycle, improve development efficiency and decrease the maintenance cost of software.
