：为了保证所提交的软件产品能够满足客户的需求，以及在使用中的可靠性，必须对所开发的软件产品进行系统而全面的测试。从保证软件质量的角度来说，软件测试是软件质量保证工程的一个重要组成部分，也是最重要的质量保证手段。无论是面向对象软件开发还是传统的面向过程软件开发，软件测试归根结底要通过一套比较成熟的测试技术和方法来实现。文中从错误避免、检错和容错三个方面阐述了软件测试技术，并介绍了通过测试和失败测试两种软件测试方法。-: In order to ensure that the delivered software products to meet customer needs, as well as the reliability in use, must be developed in a systematic and comprehensive software product testing. From the perspective of software quality assurance, software quality assurance software testing is an important part of the project is the most important means of quality assurance. Whether or traditional object-oriented software development process-oriented software development, software testing in the final analysis to be tested through a set of relatively mature technologies and methods to achieve. Avoid the text from the error, error detection and fault-tolerant three aspects of software testing technology, and through the introduction of two software testing and test methods fail test.
