ETSI ES 202 782定义了TTCN-3的实时和性能测试支持包。可以使用TTCN-3 用于在各种通信端口上进行所有类型的无功系统测试。典型区域 应用程序包括协议测试（包括移动和互联网协议）、服务测试（包括补充协议） 服务）、模块测试、基于OMG CORBA的平台、API等的测试。TTCN-3不限于一致性 测试，并可用于许多其他类型的测试，包括互操作性、健壮性、回归、系统和性能 集成测试。物理层协议测试套件的规范不在本协议的范围内 文件TTCN-3软件包旨在定义额外的TTCN-3概念，这些概念在 TTCN-3核心语言，但作为适用于专用应用和/或 TTCN-3的用途。而TTCN-3软件包的设计考虑了核心语言组合使用的一致性 对于许多包，该包与其他包结合使用的具体用法和指南 不在本文件的范围之内。

ETSI ES 202 782 defines the real time and performance testing support package of TTCN-3. TTCN-3 can be used for the specification of all types of reactive system tests over a variety of communication ports. Typical areas of application are protocol testing (including mobile and Internet protocols), service testing (including supplementary services), module testing, testing of OMG CORBA based platforms, APIs, etc. TTCN-3 is not restricted to conformance testing and can be used for many other kinds of testing including interoperability, robustness, regression, system and integration testing. The specification of test suites for physical layer protocols is outside the scope of the present document.TTCN-3 packages are intended to define additional TTCN-3 concepts, which are not mandatory as concepts in the TTCN-3 core language, but which are optional as part of a package which is suited for dedicated applications and/or usages of TTCN-3.While the design of TTCN-3 package has taken into account the consistency of a combined usage of the core language with a number of packages, the concrete usages of and guidelines for this package in combination with other packages is outside the scope of the present document.
