【摘要】:Web服務(wù)是松散耦合的,可復(fù)用的軟件模塊,是一種在XML基礎(chǔ)上發(fā)展起來(lái)的分布式計(jì)算技術(shù),是一種新的網(wǎng)絡(luò)服務(wù),其目的是為在Internet上不同操作系統(tǒng),,硬件平臺(tái)和編程語(yǔ)言間集成應(yīng)用軟件提供支持,方便應(yīng)用的實(shí)現(xiàn)和發(fā)布。隨著Web服務(wù)的發(fā)展和廣泛應(yīng)用,人們發(fā)現(xiàn)Web服務(wù)的真正價(jià)值在于通過(guò)服務(wù)組合(Composition)使業(yè)務(wù)合作伙伴之間可以進(jìn)行電子商務(wù)對(duì)話,提供增值服務(wù)的能力。為了實(shí)現(xiàn)共同的業(yè)務(wù)目標(biāo),Web服務(wù)編排指定了多個(gè)參與者之間的交互序列。如何測(cè)試編排規(guī)范和編排實(shí)現(xiàn)的相符性是一個(gè)重要的研究課題。為此,本文力圖尋找方法和工具支持編排相符性的測(cè)試。 在本文中,作者對(duì)編排場(chǎng)景進(jìn)行精化,以獲得更有效的測(cè)試場(chǎng)景,顯著降低測(cè)試開(kāi)銷(xiāo)。具體的,根據(jù)編排場(chǎng)景中XMLSchema類(lèi)型定義,將交互類(lèi)型劃分為子類(lèi)型并將劃分輸入到組合工具Cascade中,得到一組變量的組合。將Cascade的輸出轉(zhuǎn)換為精化的類(lèi)型樹(shù)并對(duì)精化后的場(chǎng)景進(jìn)行測(cè)試。為了實(shí)現(xiàn)基于編排場(chǎng)景的Web服務(wù)相符性測(cè)試,還需要解決測(cè)試數(shù)據(jù)(XML文檔)的生成問(wèn)題;诰蟮木幣艌(chǎng)景本文提出了生成XML文檔的方法。給出了由精化的類(lèi)型樹(shù)生成modified樹(shù)和節(jié)點(diǎn)數(shù)據(jù)集的算法。為滿足不同需要,提供了多種節(jié)點(diǎn)取值策略供選擇。最后,本文介紹了作者開(kāi)發(fā)的原型工具集以便自動(dòng)化的生成測(cè)試數(shù)據(jù),并設(shè)計(jì)了實(shí)驗(yàn)來(lái)說(shuō)明測(cè)試框架的可行性。
[Abstract]:Web services are loosely coupled, reusable software modules, a distributed computing technology developed on the basis of XML, is a new network service, which aims at different operating systems on the Internet. Integrated application software between hardware platform and programming language provides support to facilitate the implementation and release of applications. With the development and wide application of Web services, it is found that the real value of Web services lies in the ability to provide value-added services by making e-commerce dialogues among business partners through service composition. In order to achieve common business objectives, web service orchestration specifies a sequence of interactions between multiple participants. How to test the conformance between orchestration specification and orchestration implementation is an important research topic. Therefore, this paper tries to find methods and tools to support orchestration compliance testing. In this paper, the author refines the orchestration scenarios to obtain more efficient test scenarios and significantly reduce the test overhead. Specifically, according to the XML Schema type definition in the orchestration scenario, the interaction type is divided into subtypes and the partition is input into the composition tool Cascade, and a set of variables is combined. The output of the Cascade is converted into a refined type tree and the refined scenario is tested. In order to realize the test of Web service conformity based on orchestration scenario, we also need to solve the problem of generating test data and XML document. Based on the refined orchestration scenario, this paper presents a method to generate XML documents. An algorithm for generating modified trees and node datasets from refined type trees is presented. In order to meet different needs, a variety of node selection strategies are provided. Finally, this paper introduces the prototype tool set developed by the author to generate test data automatically, and designs experiments to illustrate the feasibility of the test framework.
