User Stories and Case Analysis(用

作者: 我要走多远 | 来源:发表于2014-11-01 07:26 被阅读247次

    User stories represent a lightweight approach to use case analysis, a term traditionally used in software engineering to describe a similar process.

     在传统的软件工程中,人们使用案例分析。而用户故事(user stories)是一种了轻量级的使用用户案例分析的方式,描述了相似的流程。

     A full use case analysis would include the use case name; actor(s); goals of the action; summary of the use case; preconditions (state of the world before the action);

     一个完成的使用案例分析,应当包括:案例的名字;参与者(actor);行为的目的;使用案例总结;前提条件(在这个行为前,世界的状体);

    steps occurring in the scenario (both the actions performed by the user and the system’s responses); related use cases; and postconditions (state of the world after the action). 出现在这个场景中的步骤(包括用户的行为和系统回复的行为);

    相关的用户案例;和后条件(这个行为结束后的世界的状态); 

    A use case diagram is a UML-like diagram (see Chapter 10) with stick figures standing in for the actors, and can be used to generalize or extend use cases or to include a use case by reference.

     一个 使用案例图表 图表类似UML图表,并用小棍子代表参与者,并且可以通过引用来生成、扩充、包含其他用户案例。

     For example, if we have a use case for “user logs in” and another use case for “logged-in user views her account summary”, the latter could include the former by reference, since a precondition to the second use case is that the user has logged in.” 

    例如,我们有一个“用户登录”的使用案例,并且有另一个叫做“登录后的用户,查看他的账户总结”的使用案例。 后者可以通过引用来包括前者,既然登录是第二个用户案例的一个前置条件。
