【摘要】：Web服务作为W3C认证的面向服务架构(service-oriented architecture,SOA)的实现方式,对外提供可用于黑盒测试的接口文档,如何有效地自动化生成测试用例成为Web服务自动化测试的首要问题。现有的测试工具对WSDL(Web services description language)的文档结构和数据之间的依赖关系考虑不足,且缺乏有效的测试数据生成方法,进而导致测试效率不高以及生成的测试用例无法覆盖全部的测试需求。为此,提出了Web服务自动化测试的技术框架,并实现了支持此框架的原型工具。该框架基于WSDL文档解析获取覆盖结构特征的SOAP(simple object access protocol)骨架集合,并采用可变力度组合测试模型生成满足元素组合的SOAP封装消息,之后通过有限状态机/接口契约模型获取操作序列测试路径,保证了操作序列测试数据的有效性。案例结果表明了所提框架生成的测试数据能够更好地满足测试需求,达到理想的测试覆盖率,并能够检测出更多的错误,且在用例规模上优于现有的方法。
[Abstract]:As the implementation of W3C certified Service-Oriented Architecture (service-oriented architecture,SOA), Web Services provides interface documents for black-box testing. How to automate the generation of test cases has become the most important issue for Web services automated testing. The existing testing tools do not consider the WSDL (Web services description language) document structure and data dependency, and lack of effective test data generation method. Therefore, the test efficiency is low and the generated test cases can not cover all the test requirements. Therefore, a technical framework for automated testing of Web services is proposed, and a prototype tool supporting this framework is implemented. Based on the analysis of WSDL documents, the framework acquires the SOAP (simple object access protocol) skeleton set of overlay structural features, and generates the SOAP encapsulation message satisfying the composition of elements by using the variable strength combination test model. Then the test path of operation sequence is obtained by finite state machine / interface contract model, which ensures the validity of operation sequence test data. The case results show that the test data generated by the proposed framework can better meet the test requirements, achieve ideal test coverage, detect more errors, and outperform the existing methods in the scale of use cases.
