基于BPEL的Web服务组合测试路径生成

BPEL based Web service composition test path generation

文章以更好地实现服务组合测试为目标,提出基于BPEL的Web服务组合测试路径生成方法。首先将应用于描述BPEL流程的模型WFDAG,通过DAG对Web服务工作流进行建模,有效保证数据流测试路径的生成。然后以此为基础应用扩展后的分析方法,并采取覆盖原则ALL-USES进行数据流测试。最后以变量信息为指标分析所构建的WFDAG模型,从而获取符合所有既定数据流标准的测试路径。

With the goal of better realizing service composition testing,this paper proposes a method for generating Web service composition test paths based on BPEL.First,the model WFDAG,which describes the BPEL process,is applied to model the Web service workflow through DAG to effectively ensure the generation of data flow test paths.Then,based on this,the extended analysis method is applied,and the coverage principle ALL-USES is adopted for data flow testing.Finally,the constructed WFDAG model is analyzed with variable information as an indicator,so as to obtain test paths that meet all established data flow standards.
