什么是UML？统一建模语言详解

UML统一建模语言的简称，是一种标准化的建模语言，由一组集成的图表组成，开发用于帮助系统和软件开发人员指定，可视化，构建和记录软件系统的工件，以及业务建模和其他非软件系统。UML代表了一系列最佳工程实践，这些实践已被证明在大型复杂系统的建模方面取得了成功。UML是开发面向对象软件和软件开发过程中非常重要的一部分。UML主要使用图形符号来表达软件项目的设计。使用UML有助于项目团队进行沟通，探索潜在设计，并验证软件的架构设计。在本文中，我们将为您提供有关什么是UML的详细信息。

A use case is a list of actions or event steps that typically define the interaction between an actor (called an actor in Unified Modeling Language (UML)) and a system to achieve a goal. Actors can be people or other external systems. In systems engineering, use cases are used at a higher level than in software engineering and usually represent task or stakeholder goals.

如何编写有效的用例

One of the most difficult problems in software development is capturing exactly what you want to build. Inaccurate requirements can eventually lead to significant project delays, rework, or even abandonment. Effective application of use case techniques can help your team capture requirements from the user’s perspective, which can be easily understood by both the end user and your team. Use case-driven development supports subsequent development activities such as analysis, design, and testing.

编写用例事件流程中的测试程序

In the area of software testing, “use case” and “test case” are the most critical and closely interrelated terms, but they are quite different. A use case tells us how a system will behave or perform a given task under given conditions. A test case contains the actual test data, the instruction set of the system, and the expected results of the interaction with the system.
