Software Testing Introduction
QA Services During Development Phase:
Test planning Test case generation Code analysis Unit testing Test driver development White box testing Defect analysis Bug fixes
development is nearing completion; minor design changes may still be made as a result of such testing. Typically done by end-users or others, not by programmers or testers.
– To find out the bugs in the docs\software.
What's the principle during testing?
– Test as early as possible – Do proper testing, avoid excessive testing and
Inadequate Testing - no one will know
whether or not the program is any good until the customer complains or systems crash.

基本现状
• 学校 – 一门课程 – 40多本教科书,很多学校都设置 • 工业界 – 一个职业
– “Microsoft in terms of this quality stuff–we have as many testers as we have developers. And testers spend all their time testing, and developers spend half their time testing. We’re more of a testing, a quality software organization than we’re software organizations”,By Bill gates, 2002

测试与软件开发各阶段的关系
• 软件开发过程是一个自顶向下逐步细化的过 程。 –系统规划阶段定义项目范围 –系统分析阶段建立数据域、功能和性能 需求、约束等 –系统设计阶段建立物理设计蓝图 –系统构造阶段把物理设计蓝图用某种程 序设计语言转换成程序代码 • 测试过程是依相反顺序安排的自底向上逐步 集成的过程。

软件测试的不修复原则
并非所有软件缺陷都能修复,其原因在于: • 没有足够的时间 • 不算真正的软件缺陷 • 修复的风险太大 • 不值得修复

Pareto原则
Pareto原则暗示 着测试发现的 错误中的80% 很可能起源于 程序模块中的 20%。

软件测试的目的(1)
• 基于不同的立场,存在着两种完全不同的测 试目的。 – 从用户角度出发,普遍希望通过软件测试 暴露软件中隐藏的错误和缺陷,以考虑是 否可接受该产品。 – 从软件开发人员角度出发,则希望测试成 为表明软件产品中不存在错误的过程,验 证该软件已正确地实现了用户的需求,确 立人们对软件质量的信心

Why Test?
If you don’t start planning for the test at the time the functional requirements are formed, you’ll never know why you’re conducting the test.
IV&V stands for “independent verification and validation”

软件测试ST和软件质量SQ的关系
刘冬梅
• 计算机产品质量检验员
(软件测试工程师)
• ST是SQ的手段之一,是高SQ的必要非充分条件。
• 软件的高质量是分析设计出来的,而不是靠测试修 补出来的。
• 软件测试是软件生存周期内的一个重要阶段,是软 件质量保证的重要步骤,是软件投入运行前,对软 件需求分析、设计规格说明和编码进行最终复审的 活动”----1997年,朱鸿,《软件质量保障与测试 》

软件测试 基本概念
Software Testing Techniques
几个术语(1)
• 失败(Failure) - 指不完全符合给定的需求,实际结果或行为与期望
结果或行为之间的偏差。 - 当故障执行时有时会发生失败 - 事故(Incident)是警告用户注意所出现的失败 • 故障(Fault) - 软件中的静态缺陷 (Defect) - 故障屏蔽指一个故障会被系统的某个或某些故障所
,决定此时的产品是否满足前一个阶段所确定需 求的过程。
(Are you building the product right?是否正 确地构造软件?)
软件测试方法介绍
软件测试方法介绍1测试分类编辑β测试,英文是Beta testing。
又称Beta测试,用户验收测试(UAT)。
β测试是软件的多个用户在一个或多个用户的实际使用环境下进行的测试。
开发者通常不在测试现场,Beta测试不能由程序员或测试员完成。
当开发和测试要完成所做的测试,而最终的错误和问题需要在最终发行前找到。
这种测试一般由最终用户或其他人员完成,不能由程序员或测试员完成。
α测试_Alpha测试α测试,英文是Alpha testing。
又称Alpha测试.Alpha测试是由一个用户在开发环境下进行的测试,也可以是公司内部的用户在模拟实际操作环境下进行的受控测试,Alpha测试不能由该系统的程序员或测试员完成。
在系统开发接近完成时对应用系统的测试;测试后,仍然会有少量的设计变更。
这种测试一般由最终用户或其他人员来完成,不能由程序员或测试员完成。
可移植性可移植性测试,英文是Portability testing。
又称兼容性测试。
可移植性测试是指测试软件是否可以被成功移植到指定的硬件或软件平台上。
UI测试用户界面测试,英文是User interface testing。
又称UI测试。
用户界面,英文是User interface。
是指软件中的可见外观及其底层与用户交互的部分(菜单、对话框、窗口和其它控件)。
用户界面测试是指测试用户界面的风格是否满足客户要求,文字是否正确,页面是否美观,文字,图片组合是否完美,操作是否友好等等。
UI 测试的目标是确保用户界面会通过测试对象的功能来为用户提供相应的访问或浏览功能。
确保用户界面符合公司或行业的标准。
包括用户友好性、人性化、易操作性测试。
用户界面测试用户分析软件用户界面的设计是否合乎用户期望或要求。
它常常包括菜单,对话框及对话框上所有按钮,文字,出错提示,帮助信息 (Menu 和Help content)等方面的测试。
比如,测试Microsoft Excel中插入符号功能所用的对话框的大小,所有按钮是否对齐,字符串字体大小,出错信息内容和字体大小,工具栏位置/图标等等。

在残酷的竞争中,软件的质量自然而然成为了软件开发的重要目标和竞争的首要条件。
质量差的软件产品,不仅增加了维护的费用,还可能由此导致风险,从而影响到开发商本身的利益。
所以说,质量是重中之重。
With the rapid development of information technologies, the software applications areapplied to various industries. As the competitions is becoming more and more drastic, thesoftware quality no doubt becomes the important objective of software development andthe primary condition of competitions. For a software product with poor quality, it needsmore maintenance cost, and may increase risk. This will affect the benefits of developer.Obviously, the quality becomes first.缺陷存在原因Reasons that defects exist1、交流不够、交流上有误解或者根本不进行交流Communications are insufficient, or thereare misunderstandings between the communications, or no communication exists at all.2、软件复杂性The software is too complex.3、程序设计错误Perform the wrong programming.4、需求变化The requirements varied.5、时间压力 Be under the pressure of time.6、代码文档贫乏Be short of code documents.7、软件开发工具Wrong development tools are used.软件测试定义Definition of Software Testing软件测试是为了发现错误而进行的一系列活动Software testing covers a series of activities performed in order to discover errors. 测试是为了证明程序有错,而不是证明程序无错误The purpose of testing is to testify that there exist errors in the program, not to testifythat there exists no error in the program.测试并不仅仅是为了要找出错误。

In simple words, testing is executing a system in order to identify any gaps, errors, or missing requirements in contrary to the actual requirements. According to ANSI/IEEE 1059 standard, Testing can be defined as - A process of analyzing a software item to detect the differences between existing and required conditions (that is defects/errors/bugs) and to evaluate the features of the software item .Who does T esting?It depends on the process and the associated stakeholders of the project(s). In the IT industry, large companies have a team with responsibilities to evaluate the developed software in context of the given requirements. Moreover, developers also conduct testing which is called Unit Testing . In most cases, the following professionals are involved in testing a system within their respective capacities: ∙ Software Tester∙ Software Developer∙ Project Lead/Manager∙ End UserDifferent companies have different designations for people who test the software on the basis of their experience and knowledge such as Software Tester, Software Quality Assurance Engineer, QA Analyst, etc.It is not possible to test the software at any time during its cycle. The next two sections state when testing should be started and when to end it during the SDLC.When to Start T esting?An early start to testing reduces the cost and time to rework and produce error-free software that is delivered to the client. However in Software Development Life Cycle (SDLC), testing can be started from the Requirements Gathering phase and continued till the deployment of the software. It also depends on the development model that is being used. For example, in the Waterfall model, formal testing is conducted in the testing phase; but in the incremental model, testing is performed at the end of every increment/iteration and the whole application is tested at the end. Testing is done in different forms at every phase of SDLC:1. Software Testing – OverviewSoftware Testing 2∙ During the requirement gathering phase, the analysis and verification of requirements arealso considered as testing.∙ Reviewing the design in the design phase with the intent to improve the design is alsoconsidered as testing.∙ Testing performed by a developer on completion of the code is also categorized as testing. When to Stop T esting?It is difficult to determine when to stop testing, as testing is a never-ending process and no one can claim that a software is 100% tested. The following aspects are to be considered for stopping the testing process:∙ Testing Deadlines∙ Completion of test case execution∙ Completion of functional and code coverage to a certain point∙ Bug rate falls below a certain level and no high-priority bugs are identified∙ Management decisionV erification & V alidationThese two terms are very confusing for most people, who use them interchangeably. The following table highlights the differences between verification and validation.S.N.Verification Validation 1 Verification addresses the concern: "Areyou building it right?"Validation addresses the concern: "Are you building the right thing?" 2 Ensures that the software system meetsall the functionality.Ensures that the functionalities meet the intended behavior. 3 Verification takes place first and includesthe checking for documentation, code,etc.Validation occurs after verification and mainly involves the checking of the overall product. 4Done by developers. Done by testers.Software Testing 35 It has static activities, as it includescollecting reviews, walkthroughs, andinspections to verify a software.It has dynamic activities, as it includes executing the software against the requirements. 6 It is an objective process and nosubjective decision should be needed toverify a software.It is a subjective process and involves subjective decisions on how well a software works.Software Testing 4Given below are some of the most common myths about software testing. Myth 1: Testing is Too ExpensiveReality : There is a saying, pay less for testing during software development or pay more for maintenance or correction later. Early testing saves both time and cost in many aspects, however reducing the cost without testing may result in improper design of a software application rendering the product useless.Myth 2: Testing is Time-ConsumingReality : During the SDLC phases, testing is never a time-consuming process. However diagnosing and fixing the errors identified during proper testing is a time-consuming but productive activity. Myth 3: Only Fully Developed Products are TestedReality : No doubt, testing depends on the source code but reviewing requirements and developing test cases is independent from the developed code. However iterative or incremental approach as a development life cycle model may reduce the dependency of testing on the fully developed software.Myth 4: Complete Testing is PossibleReality : It becomes an issue when a client or tester thinks that complete testing is possible. It is possible that all paths have been tested by the team but occurrence of complete testing is never possible. There might be some scenarios that are never executed by the test team or the client during the software development life cycle and may be executed once the project has been deployed.Myth 5: A Tested Software is Bug-FreeReality : This is a very common myth that the clients, project managers, and the management team believes in. No one can claim with absolute certainty that a software application is 100% bug-free even if a tester with superb testing skills has tested the application.Myth 6: Missed Defects are due to TestersReality : It is not a correct approach to blame testers for bugs that remain in the application even after testing has been performed. This myth relates to Time, Cost, and Requirements changing Constraints. However the test strategy may also result in bugs being missed by the testing team.2. Software Testing – MythsSoftware TestingMyth 7: Testers are Responsible for Quality of ProductReality: It is a very common misinterpretation that only testers or the testing team should be responsible for product quality. Tester s’ responsibilities include the identification of bugs to the stakeholders and then it is their decision whether they will fix the bug or release the software. Releasing the software at the time puts more pressure on the testers, as they will be blamed for any error.Myth 8: Test Automation should be used Wherever Possible to Reduce Time Reality: Yes, it is true that Test Automation reduces the testing time, but it is not possible to start test automation at any time during software development. Test automaton should be started when the software has been manually tested and is stable to some extent. Moreover, test automation can never be used if requirements keep changing.Myth 9: Anyone can Test a Software ApplicationReality: People outside the IT industry think and even believe that anyone can test a software and testing is not a creative job. However testers know very well that this is a myth. Thinking alternative scenarios, try to crash a software with the intent to explore potential bugs is not possible for the person who developed it.Myth 10: A Tester’s Only Task is to Fi nd BugsReality: Finding bugs in a software is the task of the testers, but at the same time, they are domain experts of the particular software. Developers are only responsible for the specific component or area that is assigned to them but testers understand the overall workings of the software, what the dependencies are, and the impacts of one module on another module.5Software TestingEnd of ebook previewIf you liked what you saw…Buy it from our store @ https://6。

Characteristics of Good Testing
Repeatable
Tests should be repeated each time the code has been changed
Once a defect has been fixed the original test that failed should be repeated Sub-sets of tests can be run against new builds as a smoke test Repeatable test results can be compared over time to measure quality and stability Tests can be reused on applications with common modules or functionality
