TMMI_测试过程改进框架_已定义级别6_非功能测试1

Purpose目的

The purpose of the Non-functional Testing process area is to improve test process capability to include non-functional testing during test planning, test design and execution. This is done by defining a test approach based on the identified non-functional product risks, establishing non-functional test specifications and executing a structured test execution process focused on non-functional testing.

非功能测试流程域的目的是提高测试过程性能，在测试计划中，测试设计和执行中包含非功能测试。这被执行通过定义测试方法基于明确的非功能产品风险。建立非功能测试说明书和执行结构化的测试执行流程，重点放在非功能测试上。

Introductory Notes 简介

Quality of products is all about satisfying stakeholders’ needs. These needs have to be translated to well-described functional (“what” the product does) and non-functional (“how” the product does it) requirements. Often the nonfunctional requirements are highly important for customer satisfaction. This process area addresses the development of a capability for non-functional testing. There is a set of principal non-functional attributes that are used to describe the quality of software products or systems. These quality attributes can be assessed using non-functional test techniques. Application of the various test techniques varies depending on the ability of the tester, the knowledge of the domain, and the attributes being addressed.

产品质量是为了满足相关利益人的需求，这些需求必须转化为详细描述的功能和非功能需求。通常非功能需求对客户满意度更重要。这个流程域促进了非功能测试能力的开发。这里有一些典型的非功能测试的属性，通常被使用来描述软件产品和系统的质量。这些质量属性被评估通过非功能测试技术。各种测试技术应用依赖了测试人员的能力，知识域，属性被跟踪。

A test approach needs to be defined based on the outcome of a non-functional product risk assessment. Depending on the level and type of non-functional risks, it is decided which requirements of the product will be tested, to what degree and how. The non-functional product risks and test approach are defined in close cooperation between test specialists and the stakeholders; testers should not make these decisions in isolation.

测试方法需要被定义，基于非功能产品风险评估的产物。基于非功能风险的水平和类别。它决定了那种产品需求将会被测试，测到那种程度，如何测试。非功能测试产品风险和测试方法被定义，需要测试人员和相关利益人紧密配合。测试人员不是单独做这个决定。

Non-functional test techniques are applied, possibly supported by tools. Test techniques are used to derive and select non-functional test conditions and create test cases from non-functional requirements and design specifications. The test cases are subsequently translated into manual test procedures and/or automated test scripts. Specific test data required to execute the non-functional test is created. During the test execution stage, the nonfunctional tests will be executed, incidents found and incident reports written.

非功能测试技术被应用。可能是通过工具支持，测试技术被使用来驱动和选择非功能测试条件，创建测试用例根据非功能需求和设计说明书。测试用例被转化为手动测试流程和自动测试脚本。特定测试数据被需要来执行非功能测试。在测试执行阶段，非功能测试将被执行。事故发现和事故报告被书写。

Scope 范围

The process area Non-functional Testing involves performing a non-functional product risk assessment and defining a test approach based on the non-functional risks identified. It also addresses the test preparation phase to derive and select non-functional test conditions and test cases, the creation of specific test data and the execution of the non-functional tests. Test environment practices, which are often critical for non-functional testing, are not addressed within this process area. They are addressed as part of the TMMi level 2 process area Test Environment and should now also support non-functional testing.

非功能测试过程域包括执行非功能产品风险评估和定义测试方法（基于非功能风险）。它同时跟踪了测试准备阶段来驱动和选择非功能测试环境和测试用例。特定测试数据被建立和非功能测试执行，测试环境实践。他们通常是非功能测试的关键点。在这个过程域不会被跟踪。
