一、什么是DoD?

当你有两个或更多的人参与同一个事情的时候,我们的“团队”就产生了,这时我们最重要的事情,就是要设定和统一团队的期望值,在本文中,这就是“完成标准”
一个迭代做完后,团队要进行验收,来决定本个迭代是否完成。但每个团队对于是否完成无法达成统一,有的认为编码完成,就表示任务完成了;有的认为还需要简单自测一下,确保功能可以正常使用;还有的认为需要把自动化用例写完并测试通过才算完成。
为了避免这个问题,在敏捷软件开发中,常用Definition of Done“完成的定义”来表示工作是否已完成,不同的活动有不同的完成定义。首先要知道,所有的DoD都不是一成不变的,在随着时间的推移、经验的积累、成员的变更、项目的变更,我们的DoD也会有很大的不同,所以,我们也需要定期地检查和改进。

二、 DoD的分类

有了上面的思想准备,我们再来看下面的DoD定义,就会觉得并没有那么难了。
一、迭代DoD
最典型的是迭代DoD,这也是最初DoD应用的地方。常见的一些规则有:
1.  所有代码通过静态检测,严重问题都已修改,静态分析的规则参见...
2.  所有新增代码得到人工评审
3.  所有完成的用户故事都有对应的测试用例
4.  测试用例都已执行
5.  所有完成的用户故事得到Product Owner的验证
二、发布DoD
对于发布,一般就有更加严格的要求,发布DoD的典型条款有:
1.  完成发布规划所要求的重点需求
2.  至少通过一次全量回归测试
3. 修复所有等级为1、2的缺陷,3、4级缺陷不超过20个
三、版本DoD
版本DoD就是针对每个版本上线前后的一些规则,比如:
1.  产品文档已全部更新
2.  代码已部署到产品服务器上
3.  运维在验收测试环境上冒烟通过
4.  原始需求提交人对功能已经验收通过
5.  对运维、市场、客服的新功能培训已完成
四、每日DoD
其他典型的DoD有每日DoD,典型条款有:搭建每日构建环境,晚上自动静态代码检查、编译、部署和测试,每日修复前一日构建和测试发现的缺陷和问题。
1.  下班前必须检入当天编写的代码,check in的backlog要填写清晰
2.  当天的代码必须在当天或者第2天邀请同伴进行代码评审
3.  检入的功能代码必须要有对应的单元测试(严格采用TDD)
4.  每天晚上触发静态代码检查、自动化回归测试
5.  当天持续集成、构建环境中的问题,请当天解决
五、用户故事DoD
还有针对用户故事(或者用例)的DoD,比如:
1.  用户故事最终的描述符合INVEST
2.  用户故事得到测试用例的对应覆盖
3.  用户故事得到对应的自动化测试用例
4.  用户故事得到PO试用并初步认可
当测试集比较大的时候,无法在1天之内完成测试,可以开展每周全量回归自动化测试,这样就有每周DoD,典型条款有:
1.  上上周发现的缺陷是否解决
2.  上周新增功能的自动化测试是否加入到每周测试集。
最后需要注意的是,对于验收标准,并不一定是由Product owner决定,要根据显示情况而定,每个团队都要根据自己的情况选择合适的DoD原则CORNERSTONE 提供了包括任务/需求/测试管理、迭代规划、缺陷追踪、报表统计、团队协作、WIKI、共享文件和日历等功能模块,20人以下团队可免费使用,点击即可免费注册CORNERSTONE
