The Research Of Automated Prototype Generation Method Based On System Sequence Diagrams

Along with the development of modem software technology , Prototype development tecnology is getting more and more attention . Prototype can bring a lot of advantage , for example , determining requirement , reacting to changement , reducing risk and so on . Prototype brings there advantage , while , it brings the problem of development cost, so , the prototype automatization get some progress . Prototype automatization make the prototype generating procedure automatic and reduce manual work , so , it has a big effect to the problem of prototype development cost.In the past few decades , along with the appearance of the Object-Oriented sofware development methodology , we get a predominant production UML . UML has been the standard modeling language , because of basing the mature software engineering , it was accepted and promulgated commendably . UML uses various graphic marks to descripe the perspective of the system , therefore, sofware devlopment personnel and user can get a primary comprehension of the system before developing an actual system .Because of the success of UML, more and more companys begin to use it to modeling therm system . therefore , if the prototype automatization method can join with UML , the method must be more useful.In this article , after researching some existent prototype automatizaition methods and analysing them disadvantage , we bring forward a new prototype automatization method which bases on the system sequence diagrams . This method combine the prototype automatization and the UML creatively and provide a new method of transition from requirement engneering to user interface prototype.Firstly , This method require the system analyst produce a system usecase model and scenario model during the system analysing phase , the scenario model is descripted by system sequence diagrams , we add some ui restriction to there system sequence diagrams to make it have rich ui information ; Then , applying our arithmetic to there diagrams can bring out an excutable user interface prototype . Finally , after researching the test-driven software development technology , we found that we can use mock object mechanism to make our prototype more detailed. we will depict our arithmetic in this article concretely .
