The ebXML Test Framework presented by IIC (Implementation, Interoperability and Conformance Technical Committee) is intended to support conformance and interoperability testing for ebXML specifications. It describes a test framework and its software components, how these can be combined to create a test harness for each type of ebXML testing. While implementing the test framework², we found that it requires its client part (adapters for test target) to be adaptive and operative to any kind of message handler system. For the purpose, we cannot find better way than Web Service approach, based on SOAP and WSDL, for the test framework. By the approach, we coupled tightly a target system to be tested and test framework asynchronously. For detecting deceits in testing processes more easily, we propose a dually coupled messaging framework between a test service and a test driver. In this paper, we introduce the implementation architecture for the test framework and a test procedure on the adopted test actions.
