Abstract

Web service choreography specifies a sequence of interactions among multiple services. How to test if a Web service conforms with given choreography specification is a challenging question. It is important to generate test data (i.e. XML instance) based on the choreography. Since choreography scenarios describe expected interactions among multiple participants, it is possible to generate test data based on those scenarios. This paper presents a set of test data generating rules and algorithms based on refined type trees, which are obtained from choreography scenario and corresponding XML Schema type document. We have built a prototype tool to support automatic test data generation and illustrate the process of generating XML instances via a purchase order choreography scenario example.
编排基于场景的测试数据生成
Web服务编排指定了多个服务之间的交互序列。如何测试Web服务是否符合给定的编排规范是一个具有挑战性的问题。基于编排生成测试数据(即XML实例)是很重要的。由于编排场景描述了多个参与者之间预期的交互,因此可以基于这些场景生成测试数据。本文提出了一套基于精细化类型树的测试数据生成规则和算法,该规则和算法来源于编排场景和相应的XML Schema类型文档。我们已经构建了一个原型工具来支持自动测试数据生成,并通过一个采购订单编排场景示例说明生成XML实例的过程。
