Testcomplete基础培训

TestComplete基础培训,陈能技,TestComplete简介,TestComplete是这几年测试工具领域异军突起的一款自动化测试工具，由AutomatedQA出品，这几年迅速发展，并且屡获大奖，例如最近就获得Jolt的08年度测试工具Productivity奖。TestComplete的最大特点是支持VBScript、DelphiScript、JScript、C#Script、C+Script多种脚本语言，可以让测试人员选择自己熟悉的脚本语言进行自动化脚本的编写。另外，TC支持.NET、Delphi、Java等流行语言和平台下的软件的自动化功能测试，支持WEB功能和性能测试，支持分布式测试、单元测试等多种测试方式。与QTP、Robot等主流大牌厂商的自动化测试工具相比，TC的优势除了上面所说的，还有价格也是其主要竞争优势之一。,安装,可到www.AutomatedQA.com下载TestComplete的最新版本。,TC安装的要求-最小系统需求,IntelPentiumII400MHzorhigher(PentiumIII800MHzrecommended).MicrosoftWindows98,WindowsME,Windows2000,WindowsXP(both32-bitand64-biteditions),WindowsVista(both32-bitand64-biteditions),WindowsServer2003(both32-bitand64-biteditions)orWindowsNT4.0withServicePack6orlater.MicrosoftInternetExplorer5.0orlater.Memory:128MBofRAM(256MBormorerecommended).250MBharddiskspace.VGAorhigherresolutionmonitor.Mouseorotherpointingdevice.,TC安装的要求-额外需求,TotestJavaOpenApplications,youmusthaveoneofthefollowingJavavirtualmachinesinstalledonyourcomputer:MSVM,build3309orlater.SunJDK(orJRE)v.1.1.8orlater.BEAJRockit5.0.Totest.NETOpenApplications,theMicrosoft.NETFrameworkv.1.0.3705orlaterisrequired.ToexecuteTestCompletetestsfromtestprojectscreatedinMicrosoftVisualStudio2005,MicrosoftVisualStudio2005TeamSuitever.8.0.50727.42orlaterorMicrosoftVisualStudio2005TeamEditionforSoftwareTestersver.8.0.50727.42orlaterarerequired.ToinstallTestCompletesMicrosoftVisualStudio2005TeamFoundationIntegrationpackage,MicrosoftVisualStudio2005TeamFoundationServerReleaseisrequired.Toperformloadtestingofwebservers,MicrosoftWindows2000,WindowXP,WindowsVista,WindowsServer2003orWindowsNTwithServicePack6.0orlaterisrequired.Also,itisrecommendedthatyourcomputermeetsthefollowingrequirements:MinimalConfigurationIntelPentiumIII800MHz256ofRAM(for300virtualusers)RecommendedConfigurationIntelPentium43GHzwithHyperThreading1GbofRAM,TestComplete支持的测试类型,ManualTesting（手工测试）FunctionalTesting（功能测试）UnitTesting（单元测试）RegressionTesting（回归测试）DistributedTesting（分布式测试）HTTPPerformanceTesting（HTTP性能测试）,白盒应用程序,TestCompletewillbeabletoautomaticallyseedeeplyinside.NETandJavaapplicationwithoutanychangestotheapplicationjustbecauseofthenatureofmetadatagenerationof.NETandJavaapplicationwhichareeasytoreflect.Reflectionistheabilitytoretrieveinternalobjects,properties,methodsandevents.SothesearealwayscalledWhiteBoxApplications.NET和Java程序是基于中间代码构建的，所以TC可以直接通过反射读取其中的内部对象、属性、方法和事件。SomeApplicationsarewritteninC,C+orDelphi,theseapplicationsaremainlyBlackBoxapplicationsbutcouldbecompiledinsuchawaytoenablethemtobecomeWhiteBoxApplications.ThatwouldrequirecompilingwithDebuginformationenabledandtheinclusionofsomeTestCompletefilesintotheprojecttoenablereflectionofallprogrammetadata.C、C+、Delphi这类程序如果在编译时做相应的设置，则也可以变成WhiteBoxApplications.,关于测试工具的各种原理，请参考第2章自动化测试工具,创建Project,可通过ProjectWizard创建测试项目，其中ProjectItem包括：Events、HTTPLoadTesting、Low-LevelProcedureCollection、ManualTest、Script、Stores、UnitTesting、Win32TestedApplication等。其中Win32TestedApplication中可设置被测试应用程序的RunMode，包括4种运行模式：Simple、RunAs、Debug、Profile。一般都选择Simple，如果希望在AQTime下运行程序以便获得测试覆盖率、代码执行效率等信息的话则可选用Profile。,ObjectBrowser,ProcessFilterHightlightOnScreenFinderToolChangeProperty,TestLog,TC的Log可以写6种类型的信息：MessageWarningErrorEventsImageFile,Debug,断点步入、步进调试查看变量值,CheckPoint,RegionFileObject,数据驱动,TC用DDT来支持数据驱动测试，DDT包括3种类型：(1)CVSDriverisusedtoreadtextfilesuchascommadelimited(default)ortabdelimited(usingaschema.inifile).Bydefaultthefirstrowistheheaderinformation(orcolumnnames)forthedriver.(2)ExcelDriverisusedtoreadanExcelspreadsheet.Thefirstrowofthesheetistheheaderinformationforthedriver.(3)ADODriverisagenericdrivertoreadinADOcompatibledatasource.,更多关于测试框架的内容，请参考第6章自动化测试框架的搭建,EventHandling,TC中可处理的一般事件包括：OnLogCloseNodeOccurswhenalogfolderispopoffthelog.OnLogCreateNodeOccurswhenanewlogfolderisappendedonthelog.OnLogErrorOccurswhenanerrormessageispostedtothelog.OnLogEventOccurswhenaneventmessageispostedtothelog.OnLogFileOccurswhenafileispostedtothelog.OnLogLinkOccurswhenafilereference(link)ispostedtothelog.OnLogMessageOccurswhenainformationmessageispostedtothelog.OnLogPictureOccurswhenapicture(image)ispostedtothelog.OnLogWarningOccurswhenawarningmessageispostedtothelog.OnOverlappingWindowOccurswhenaoverlappingwindowappears.OnTimeoutOccurswhenatimeoutexpiresinaprojectorprojectsuite.OnUnexpectedWindowOccurswhenanunexpectedwindowappears.OnValidateOccurswhentheobjectsValidatemethodiscalled.下面的脚本用于处理OnLogError事件，当Log一个错误时，把当前的桌面截屏并写入日志：SubGeneralEvents_OnLogError(Sender,LogParams)CallLog.Picture(Sys.Desktop,LogParams.Str)EndSub,关于非预期窗口的处理，请参考第12章非预期窗口的处理,冒烟测试,冒烟测试是自动化测试中最重要，也最应该实现的测试。冒烟测试能为开发和QA节省大量的时间，一个好的冒烟测试应该：（1）能快速地运行asmoketestshouldnotlastforhoursbutminutesandtestthemostcrucialfunctionality（2）快速发现错误并报告错误assoonasafailureisdetectedinthesmoketestshouldendandtriggerafailurenotification（3）覆盖大范围的功能Coverabroadrangeoffunctionality,focusingonbreadthnotdepth（4）需要的
