Mapping CORBA IDL to TTCN-3 based on IDL to TTCN-2 mappings
نویسنده
چکیده
A widely used middleware for Internet based distributed systems is CORBA where interfaces are described with IDL. TTCN is used as a standardised test description language in the telecommunication area. The current version of TTCN, version 3, is among others designed to test CORBA based systems. This requires a mapping of IDL to TTCN-3 and therefore, a new mapping for TTCN-3 in contrast to the existing one for TTCN-2 gets necessary. This paper points out the new features of the TTCN-3 standard and how they can be used for an improved IDL mapping.

A Definition and Utilization of OMG IDL to TTCN-3 Mappings
An established middleware technology for Internet-based distributed systems is CORBA, where interfaces are described with IDL. TTCN is a standardised test description language widely used in the telecommunications area. The current version of TTCN, version 3 (TTCN-3), is among others designed to test CORBAbased systems. This paper presents a definition of the OMG IDL to TTCN-3 mappings, which f...
متن کاملConformance Testing of Corba Services Using Tree and Tabular Combined Notation
This paper presents a formal approach to conformance testing of CORBAbased distributed services using TTCN framework. It discusses mapping of CORBA IDL to TTCN, concentrating on the obstacles and the design issues to be considered. The paper overviews the architecture of the CORBA/TTCN gateway, which acts as an intermediary between test environment and system under test (SUT). It goes through a...
متن کاملUML-based test specification for communication systems: a methodology for the use of MSC and IDL in testing
Nowadays, the complexity of modern telecommunication systems has increased significantly and the requirement for thorough and systematic testing is undisputed. The Testing and Test Control Notation (version 3) (TTCN-3) is an universal and standardised language for the specification and implementation of tests for communication systems. Many systems and in particular object-oriented systems are ...
متن کاملAn IDL to SDL2000 compiler
Distributed systems evolution has led telecommunication management network (TMN) systems to use object-oriented middleware paradigm, mainly CORBA (Common Object Request Broker Architecture). CORBA only includes a mechanism for defining object interfaces not for specifying the behaviour of these objects. The behaviour of a TMN system has to follow concrete and restrictive specifications, which a...
متن کاملConstructing IDL Views on Relational Databases
Data collections are distributed at many different sites and stored in numerous different database management systems. The industry standard CORBA can help to alleviate the technical problems of distribution and diverging data formats. In a CORBA environment, data structures can be represented using the Interface Definition Language IDL. Manually coding a server, which implements the IDL throug...
