These contracts explicitly state functional characteristics as well as non - functional quality - of - service , or qos capabilities and requirements 这些约定显式地声明功能性特征以及非功能性（服务质量或qos ）特征和需求。
As we saw earlier , requirement types might include business needs , features , and functional and non - functional software requirements 正如我们前面看到的，需求类型可能包括业务需要、特性以及功能性和非功能性的软件需求。
If something isn ' t working properly , the control center will change the icon next to the non - functioning module to red to alert you of a problem 如果是工作不正常,控制中心,将改变图标旁边的非功能模块为红色,以提醒你一个问题
For example , the non - functional and operational requirements such as security , directory services , reliability , and performance become more complex 比如说，非功能性操作需求，安全性、目录服务、可靠性、性能等都变得更加复杂。
One of the important reasons for the complexity is that the complexity of algorithms and distributed protocols used for non - functional requirements 造成这种复杂性的一个重要原因是满足非功能性要求的分布式协议和算法的复杂性。
Table ( 2 ) lists different categories of non - functional testing along with examples of attributes and brief test procedures for each one of them 表二列出了非功能性测试的不同类型，并举出了属性的例子，同时简述了每一类的测试流程。
This warrants that nft betaken up as early in the test cycle as possible or the fix may adversely affect meeting the delivery schedules 这就说明非功能性测试需要在测试周期中尽可能早的进行，否则修复活动将反过来影响到提交进度的实现。
It is very important that an application architect or designer create a solution based on both the functional and non - functional requirements and expectations 应用程序架构师和设计人员必须根据功能和非功能性需求以及例外情况创建解决方案。
Nft can be done in the framework of existing test process , and we have outlined activities that can be performed as part of nft in the test phases 非功能性测试能够在已存在的测试流程的框架中实施，这里已经概述了可以作为非功能性测试的活动。
The main difference from functionality test execution is that the preparation time normally is substantially more than the actual execution time 与功能性测试的执行相比，非功能性测试的最大的不同之处在于准备时间比起实际运行时间来要长的多。
