一种基于CORBA和UML的网管接口TTCN-3测试套生成方法

ORBA is one of the mainstream technologies for network management interfaces. Currently, UML is generally used as the protocol-neutral information modeling language in network management, and IDL is used as a protocl-specific implementation for CORBA-based interfaces. UML and IDL jointly compose the complete definition of a network management interface. But, the current automatic testing for network mangement interfaces still needs to be improved, especially for function test and semantic test of intefaces, which are most likely relying on manual testing. As a standard test description language, TTCN-3 can be used to improve the testing automation degree of network management interfaces. Based on the standard static mapping from IDL to TTCN-3 specified by ETSI, this paper proposed a kind of TTCN-3 testing suits generation method from IDL definition and UML sequence diagrams, provided the generaiton rules to generate test scripts, designed the system structure of the TTCN-3 test suits generator, and implemented a prototype system. The prototype can automatically generate executable TTCN-3 test suits for CORBA-based network management intefaces, thus improving the automation level of funtion and process test of management interfaces in a certain degree.
