The testing research based on an extended Petri net of EEPC
基于扩展Petri网的EEPC测试模型研究

In the Grid testing,the integration testing was one of the most important.For cutting down the testing cost,the extended Petri net and Extended Event-Process Chain(EEPC) model were taken as the researching base during the integration testing of components.After fusing adequately the excellences of Petri and EEPC in structure expression,qualitative and quantitative analysis,etc.,the PRI of components would be sorted through quantitatively analyzing some parameter,such as the using frequency of components.In the end,the testing emphasis would be put on the components that had the more upper PRI,in order to reduce the testing cost in an across-the-board status.
