摘要：随着信息技术的不断发展，软件产品开始应用到各个领域，软件产品的质量自然成为人们关注的焦点。软件测试是软件开发过程中的一个重要阶段，是保证软件质量最重要的手段，因此越来越受到软件企业和用户的重视。
本文在参阅大量有关软件测试的资料文献的基础上，结合GDES系统的测试，对软件测试从理论到实践进行了研究和探索。针对于GDES系统的庞大性和复杂性，运用一定的测试手段，对GDES系统进行了全面系统的测试。
本文首先介绍了软件测试的一些基本概念和发展现状，包括软件测试的概念、测试的重要性以及目前软件测试行业发展现状。其次，系统阐述了软件测试技术的相关理论和方法，包括软件测试的原则和目标，系统测试的主要内容，以及软件测试的主要方法如静态测试，动态测试，黑盒测试，白盒测试等。重点阐述了软件测试的理论和方法在GDES系统测试实践中的应用，详细介绍了测试GDES系统的整个过程。针对GDES系统的测试过程，提出了一套切实可行的测试方案，其中包括需求与设计分析，创建测试计划，设计测试用例，测试的具体实施，测试结果分析及总结。
本文从理论和实践相结合的角度，给出了适合于GDES系统的软件测试的方法、测试的标准和规范、测试的管理、测试的工具、测试的技术和手段等问题。在实际工作中得到了较好的应用。

Abstract：With the development of information technology, software products are applied to various fields．Naturally, the quality of products are focused by people．Software testing is involved all important stage in the process of software development．And it is also an important means of quality assurance．So software enterprises pay more and more attention to software testing．
On the basis of a large number of literature and materials about software testing, this paper explores the theory and practice of software testing all-sided combining with the software testing practice in the GDES system．And useing certain test means, certain on overall and systematic test to GDES system direct against the hugeness and complexity of the system．
At first, this paper introduces the concept and developing status of software testing, including the concept of software testing, the importance of test, and developing status of testing industry．And then, describes related theories and methods, including the principle and objective of software testing, the content of system testing, It also introduce the software testing methods, such as static testing, dynamic testing, black-box testing, white-box testing and so on. It describes the process of testing the GDES system in detail．Expounds the application of testing theories in the GDES system testing practice．For the testing process of GDES system, a set of feasible test strategies and schemes are proposed, including requirements and design analysis, the creation of test plans, the design of test cases, the specific implementation of testing, analysis of test results and it’s summarize．
In this paper, testing methods，standards and norms，test management, test tools, technologies and means suitable for GDES system are mentioned from the perspective of combining the theory and practice，and they have got good application in practical work．
