ETSI TS 101 580-3规定了抽象测试套件（ATS）和部分协议实施额外信息 Rx接口上Diameter协议测试规范的测试（PIXIT）形式表，如 TS 129 214[1]符合相关要求和中给出的相关指南 ISO/IEC 9646-7[4]和ETS 300 406[5]。ATS中使用的测试符号为TTCN-3（见ES 201 873-1[6]）。以下测试规范和设计注意事项可在本文件正文中找到:总体测试套件结构；测试架构；测试方法和端口定义； 测试配置；TTCN风格和惯例；部分PIXIT形式；包含TTCN-3 ATS的模块。附录A提供了ATS的部分实施额外测试信息（PIXIT）形式。附录B提供了ATS的测试和测试控制符号（TTCN-3）部分。

ETSI TS 101 580-3 specifies the Abstract Test Suite (ATS) and partial Protocol Implementation eXtra Information for Testing (PIXIT) proforma for the test specifications for Diameter protocol on the Rx interface as specified in TS 129 214 [1] in compliance with the relevant requirements and in accordance with the relevant guidance given in ISO/IEC 9646-7 [4] and ETS 300 406 [5].The test notation used in the ATS is TTCN-3 (see ES 201 873-1 [6]).The following test specification and design considerations can be found in the body of the present document:the overall test suite structure;the testing architecture;the test methods and port definitions;the test configurations;TTCN styles and conventions;the partial PIXIT proforma;the modules containing the TTCN-3 ATS.Annex A provides the Partial Implementation Extra Information for Testing (PIXIT) Proforma of the ATS.Annex B provides the Testing and Test Control Notation (TTCN-3) part of the ATS.
