With the rapid development of information technology, the application software continues to expand the scale of software security issues more and more frequent, so how to guarantee and improve the quality of software has become a problem of concern. Research shows that the cost of correcting errors in the testing phase is 10 times more than that of the code, so the quality of the software can be greatly reduced by static analysis. Software testing based on defect pattern is a technique developed in recent years, the source code static analysis, mainly for software defect detec-tion and prevention automatically or semi automatically, this kind of defect detection tool due to the characteristics of high efficiency and simple to use, has been widely used in software testing. The so-called defect mode, is refers to the procedure often occurs the mistake or the flaw place presents the specific rule. Defect modes are often summed up by people or testers who are experienced in the field of program design. In this paper, the use of open source software as an experimental tool, the use of static analysis of the relevant theory, the definition of the software test software project to do some of the existing problems.%随着信息技术的飞速发展，应用软件的规模不断扩大，越来越多的软件安全问题频频出现，因此如何保证和提高软件质量日益成为一个备受关注的问题。研究表明，在测试阶段修正错误所付出的成本比代码编写阶段多出10倍，因此以静态分析的方式来检测软件质量能大大降低投入成本。基于缺陷模式的软件测试是近些年发展起来的一种程序源代码静态分析技术，主要用于自动或者半自动的软件缺陷检测及预防，此类缺陷检测工具由于效率高和使用简单等特点在高可信软件测试中得到了广泛应用。所谓的缺陷模式，是指程序中经常发生的错误或缺陷所呈现出的特定规律。缺陷模式通常由具有领域程序设计经验的人或者测试人员总结出来。本文通过利用开源软件为实验工具，运用静态分析的相关理论，自定义检测器对软件项目做测试得出了一些存在的问题。
