本文分析可视化自动测试系统中测试信息描述的方法，简单介绍基于图元的可视化测试平台的组成结构。然后，针对测试设计过程中硬件测试环境设计、测试软件的流程设计、输入输出数据设计这三个步骤，使用XML模式分别定义了相应的描述语言。为可视化界面信息的描述设计了图描述语言，为测试信息的描述设计了测试描述语言。测试设计与生成的测试程序之间通过XML脚本文件松耦合，不仅便于与其它系统交换数据，而且便于系统本身扩展和更新。

This paper analyzes the methods commonly used to describe the  testing information in graphical automatic test systems,introduces briefly the architecture of the graphlabel based automatic test platform. Then,it defines several languages by the XML schema to describe the testing design,including hardware environment design,flowchart of the testing program,as well as the input/output data of a test. It defines a graph marked language for describing the  interface information of the test,and testing the marked language for describing parameters,programs and  data. In this way the design of a  test and the testing program are loosely related. It can exchange data with other systems and can be generalized and updated easily.
