For example, the power management system may be a Meter Data Management System (MDMS), a Customer Information System (CIS), or a Metering System (MS).

The TTCN component adapter 120 provides a communication interface for the emulator component for power management system testing driven by the TTCN script execution engine 110 to communicate with the enterprise service bus 130.

The enterprise service bus 130 registers and executes a proxy service for replicating or transmitting the power management message transmitted and received between the test target systems 200 as well as the emulator component for testing the power management system.

2 is a diagram schematically illustrating the configuration of a conformance testing apparatus for a communication protocol according to another embodiment.

Referring to FIG. 2, the conformance testing apparatus 100 of the communication protocol includes an emulator component 111 for a CIS test, a master test component 112, an emulator component 113 for MS test, a CIS SOAP (Simple Object Access Protocol) An MMS SOAP adapter 122, an MS SOAP adapter 123, an MDMS-CIS proxy 131, a CIS-MS proxy 132, and an MDMS-MS proxy 133.

The master test component 112 is driven by the TTCN script execution engine 110 and is communicated between the CIS test emulator component 111, the MS test emulator component 113 and the MDMS 201, Verify power management messages.

A CIS SOAP adapter 121 for CIS test emulator component 111 for SOAP communication with enterprise service bus 130 and an MS SOAP adapter 123 for SOAP communication with MS test emulator component 113 ) And the MTC SOAP adapter 122 for the master test component 112 to SOAP communication with the enterprise service bus 130 are driven by the TTCN component adapter 120.
