摘要软件测试是保证软件质量和可靠性重要手段，在这方面发挥着其它方法不可替代的作用。然而，软件测试是一个复杂的过程，需要耗费巨大的人力、物力和时间，约占整个软件开发成本的40%～50%。因此，提高软件测试工具的自动化程度对于确保软件开发质量、降低软件开发成本非常重要。而提高测试用例生成的自动化程度又是提高测试工具乃至整个测试过程自动化程度的关键所在，本文主要针对这一问题进行了研究和设计。本文在分析软件测试和算法基本概念的基础上，提出软件测试用例的设计是软件测试的难点之一。论文提出了基于算法的测试用例生成的内含是应用算法来求解一组优化的测试用例，其框架包括了测试环境构造、算法及测试运行环境三部分，论文给出了基于算法的测试用例生成的模型。最后以三角形分类程序为例应用算法进行测试用例生成的模拟，结果显示，应用算法进行测试用例生成可行。关键词：软件测试测试用例算法ABSTRACTSoftwaretestistheimportantmeansthatguaranteesoftwarequalityandreliability，andinthisrespect，itplaystherolethatothermethodcannotreplace.Howeversoftwaretestisacomplexprocess,itneedstoconsumehugemanpower，materialresourcesandtime，whichtakesthe40%~50%ofentiresoftwaredevelopmentcostapproximately.Therefore，raisingtheautomationlevelofsoftwaretesttoolisveryimportantforensuresoftwaredevelopmentqualityandreductionsoftwaredevelopmentcost.Andthen，themostimportantisraisingtheautomationlevelofthetestcasegenerationforraisingtheautomationleveloftesttoolandevenentiretestprocess，sothispaperstudyanddesignmainlyaccordingtothisproblem.Basedontheanalysisofbasicconceptsofsoftwaretestingandgeneticalgorithm,thisarticleproposesthatsoftwaretestcasedesignisoneofthedifficultiesofsoftwaretesting.Paperpresentstheinherentinsoftwaretestcasedesigningbasedongeneticalgorithmisusinggeneticalgorithmtosolveasetofoptimizationtestcases,andtheframeworkincludesthreepartswhicharetestenvironmentconstruction,geneticalgorithmandtheenvironmentfortest.Paperpresentsthemodelofsoftwaretestcasegenerationbasedongeneticalgorithm.Finally,wetakethetrianglecategorizerasanexample,simulatesoftwaretestcasegenerationbasedongeneticalgorithm.Theresultsdisplaythatsoftwaretestcasegenerationbasingongeneticalgorithmispossible.KEYWORDS:softwaretest,testcase,geneticalgorithm目录摘要............................................................2ABSTRACT........................................................3目录............................................................4第一章绪论.....................................................61.1问题的提出..............................................61.2国内外研究现状..........................................71.3论文研究内容............................................9第二章软件测试及算法基本概念.................................102.1软件测试基本概念.......................................102.1.1软件测试的目的...................................102.1.2软件测试的原则...................................102.2软件测试的难点.........................................112.3算法...................................................122.3.1算法的思想及流程.................................122.3.2算法的特点.......................................142.4本章小结...............................................15第三章基于算法的测试用例生成..................................163.1基于算法的测试用例生成基本内涵.........................163.1.1软件测试用例的基本内涵...........................163.1.2基于算法的测试用例生成的基本内涵.................173.2基于算法的测试用例生成...
