Abstract: 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.

摘要： 在构件集成测试过程中，为减少测试成本，以扩展的Petri网和EEPC模型为基础，充分融合了两者在结构表达、定性定量分析等方面的优点，通过对构件的使用频度等指标进行定量的分析，对构件的测试进行优先级排队，将测试重点安排在优先级高的构件上。以此达到在网格的集成测试中降低测试整体成本的目的。
