软件测试的目的决定了如何去组织测试。如果测试的目的是为了尽可能多地找出错误，那么测试就应该直接针对软件比较复杂的部分或是出错比较多的位置。如果测试目的是为了给最终用户提供具有一定可信度的质量评价，那么测试就应该直接针对在实际应用中会经常用到的模块重点测试。不同的机构会有不同的测试目的；相同的机构也可能有不同测试目的，可能是测试不同区域或是对同一区域的不同层次的测试。在谈到软件测试时，许多人都引用Grenford J. Myers在《The Art of Software Testing》一书中的观点：-software testing purposes a decision on how to organize the test. If the test is designed to identify possible errors, then the test should directly address more complex software or some more wrong position. If the purpose of testing is designed to provide end-users with a certain credibility to the quality evaluation, then the test should be directed at the practical application of the frequently used key test module. Different agencies have different testing purposes; The same institution may have some different testing purposes, testing may be different regions of the same region or different levels of testing. On the software testing, many people have cited Grenford J. Myers in "The Art of Software T esting, "a book of view :
