Research On Distributed System Testing Technology And Its Application

Along with the extensive application of network technolgy and the booming development of the related technology, distributed system massive emergences. Simultaneously object-oriented technolgy the multitudinous merits cause its widespread application.Especially the two union new characteristic, enormously expanded the software application domain, enhanced the software performance and the productive efficiency, opened a new boundary for the software industry development. However, the distributed system especially the coalescent of distributed system and object technology brought the opportunity for the software production also to bring the test huge challenge. The distributed system is take resources sharing, enhances and so on securely as the main purpose,has very many obvious new characteristics, such as concurrency, breakdown independence, deficient overall situation clock, isomerism, security, extendibility, transparent and so on.How effective carries on the distributed system in view of these new characteristics a test into software domain urgent need solution question.Firstly, this paper research correlative concept and character of distributed system , along with the new characteristic after distributing combine with the Object Oriented technology, aim at the new characteristic it expatiate the shortage of the traditional methods and the models, the important is that it put forward the new improved test process model.Secondly, this paper makes a thorough research work on distributed system test based on event constrain based on the research of common testing methods and technology of distributed system. Based on program specification, after research the tradition CSPE and E-CSPE this dissertation put post-determining event constraints and post-determining exclusive event constraints in E-CSPE,this method extends the definition of E-CSPE, and it can description event dependency relationship more completely and can find default more easily.Last, we apply above effect and theory to a practical system"Steel Roller Information Management and Produce Monitor System"and obtain better result.
