Conformance Testing of Objects in Distributed Processing Systems
نویسندگان
چکیده
The object model is a very popular paradigm for building distributed applications. Several standardisation efforts are underway that define architectures for distributed computing based on the object model. With object-based service specifications the need for conformance testing of object implementations arises to ensure that objects act as intended. The issue of conformance testing is of particular importance in distributed systems where objects from different sources and manufacturers have to interwork. We discuss the requirements of object conformance testing and the relationship to established protocol conformance testing methodology. For OMG CORBA objects, we propose a test architecture and explain the development of test cases using the standardised test notation TTCN.

Testing and Conformance within Distributed Systems
The objective of Open Distributed Processing (ODP) is to support the construction of distributed systems in a multi-vendor environment through the provision of an architectural framework that such systems must adhere to. However, without a means to assess conformance the value of this architecture is limited. This paper describes a conformance assessment methodology suitable for Open Distribute...
متن کاملHistory Management in Work ow Systems
A workkow history manager maintains the information essential for workkow monitoring and data mining as well as for recovery and authorization purposes. Certain characteristics of workkow systems like the necessity to run these systems on heterogeneous, autonomous and distributed environments and the nature of data, prevent history management in workkows to be handled by the classical data mana...
متن کاملThe Renaissance Distributed Object System
Object-oriented techniques stress modularity through narrow and rigidly deened interfaces as a way of achieving low coupling between individual software components and high cohesion in the implementation of each component. Unfortunately, in a distributed environment object-oriented interfaces are usually only enforced and usable through language mechanisms or rigid programming conventions. Both...

متن کاملFederated Objects: A Transformation Approach
Conformance is a core issue in federated networked distributed applications, that are increasingly modeled as event-based systems. Constraining an entire system to globally agreed types for exchanged objects is impractical, and structural conformance can lead to false positives. This paper adopts a transformation-centric model for federated distributed applications. Our approach is generic in t...
