Defect概念解析：当功能无法满足客户需求或偏离需求规格时即为Defect，并区分Error、Bug与Failure的差异。文档进一步说明缺陷的严重性Severity按对客户业务工作流的影响分为Blocker、Critical、Major、Minor，并给出ATM机示例。随后阐述缺陷优先级Priority（p1高、p2中、p3低）的含义及其分配角色，解释Severity与Priority的关系与常见判定逻辑。最后给出缺陷生命周期Defect Life Cycle（DLC）状态流转：new/open、assign、fixed、closed、reopen等。

为什么开发者会判定为非缺陷或拒绝

Defect If a feature or functionality is not working according to the customer requirement is called a defect. OR Deviation from the customer requirement specification is called a defect. Because of what mistake made by developers, TE will find defects in software? What is the defect between Error, Bug, Defect, Failure? 1. Mistakes done in the code, because of this we will not be able to compile the code or run the code is called error. 2. Error found in the software or application is called a defect. 3. Bug is an informal name given to defect. OR defect accepted by the developer is called Bug. 4. Many bugs/ defects present in the software leads to failure. Failure is a word used by end users. What is severity? Impact of defect on the customer business workflow 1. Blocker /shows topper 2. Critical 3. Major 4. Minor Blocker Assume that there is a defect in the application and because of this defect, TE will not be able to continue the testing for the respective module and TE will be completely blocked in testing that module. These kinds of defects are called blocker defects. 1) gmail. [www.gmail.com](www.gmail.com) Critical Assume that there is a defect in the application and we are 100% sure that this defect will affect the customer business workflow, but here TE will not be blocked, we can still continue the testing, these kinds of defects are called critical defects. Book my show Major Assume that there is a defect in the application and we really don’t know how this defect is going to impact the customer business workflow. These kind of defects are called major defects Continuation of test plan Minor Assume that there is a defect in the application and you're 100% sure that this defect will never affect the customer business . these kind of defects are called minor defects, Like spelling mistakes, alignment problems, object overlapping, all the cosmetic defects/ usability defects. Identify blocker, critical, major, minor defects(4) for ATM machines. Blocker- Take ATM card, insert to ATM machine, enter correct pin, not able to access the machine. Critical-Take an ATM card, insert it into the ATM machine, enter the wrong pin, and you're able to access the machine. Major- user is not able to get the receipt in the ATM machine. Minor- In the ATM machine receipt is generated but there is a spelling mistake in the receipt. ★ Priority Importance given to fixing the defect is called priority / How. Soon the defect needs to be fixed by the developer. There are three types of priority. 1. p1/ high: If the defect is having priority as p1, then dev should dev should immediately fix the defect . 2. p2:/ medium: If the defect is having priority as p2/ medium, the dev can fix the defect with a few test cycles or within the release . 3. p3/ low: If the defect is having priority as p3, then dev can fix the defect in the next upcoming release. Defect 1 1. When a user clicks on chats, a 404 error is displayed. Defect: severity: blocker Priority: p1 2. When users enter properly, use UN and wrong pwd. Into gmail, home page is displayed, Defect : severity : critical Priority: p1 3. In whatsapp, the user is not able to delete the chat..[ critical, p1] 4. In whatsapp mute is not working. [major, p2] 5. In flipkart, in the orders page at the bottom of the page [minor, p3] 6. In ola, user booked a cab, for some location, later it is showing some other location [ critical, p1] Identify 15 defects and give proper severity and priority. ★ Give examples for high severity and low priority. [ blocker/ critical, p3] Get me e.g. for high severity and low priority (1), low severity and high priority(1), high severity and high priority(1), low severity and low priority(1) . Who will give severity and priority. TE will give severity and priority . but priority can be changed/ given by developers, BA, customer, PM. Developers will always fix the defect which i

FAQs

什么情况下称为Defect？

当功能或特性未按客户需求工作，或偏离客户需求规格说明时，称为Defect。

Severity有哪些等级，它们如何影响测试？

Severity根据对客户业务工作流的影响分为Blocker、Critical、Major、Minor。Blocker会使测试在对应模块上被完全阻断；Critical通常不阻断测试；Major影响不明确；Minor为基本不影响业务的缺陷。

Defect Life Cycle（DLC）包含哪些主要状态？

生命周期通常从new/open开始，随后进入assign、fixed、closed；若未正确修复则可进入reopen并退回开发者。文档还提到如duplicate、not reproducible、RFE等状态选项。
