Towards automated testing of web service choreographies

Abstract

Web service choreographies have been proposed as a decentralized scalable way of composing services in a SOA environment. In spite of all the benefits of choreographies, the decentralized flow of information, the parallelism, and multiple party communication restrict the automated testing of choreographies at design and runtime. The goal of our research is to adapt the automated testing techniques used by the Agile Software Development community to the SOA context. To achieve that, we seek to develop software tools and a methodology to enable test-driven development of Choreographies. In this paper, we present our first step in that direction, a software prototype composed of ad hoc automated test case scripts for testing a web service choreography.

Verifying Service Choreography Model Based on Description Logic

“…When the properties to be checked change, the corresponding descriptions can be revised without any modification to the inspection program. Reference [48] notes that although the WS-CDL is just a description language, it is essentially an XML document; therefore, Eclipse Plugin simulators regard the WS-CDL as executable script language for interpretation and implementation. Nevertheless, the verification methods based on the simulation engine need to traverse the entire value space when handling existential and universal quantifiers, leading to a higher complexity of time and space.…”

“…An engine that can simulate WS-CDL is used to execute the WS-CDL programs during symbolic execution. Besson et al [7] adapted the automated testing techniques used by the Agile Software Development community to the SOA context to enable test-driven development of choreographies. They present the first step in that direction, a software 2 Mathematical Problems in Engineering prototype composed of ad hoc automated test case scripts for testing a web service choreography.…”

Penerapan RESTFul Web Service Pada Disain Arsitektur Sistem Informasi Pada Perguruan Tinggi (Studi Kasus: STARS UKSW)

“…RESTFul yang peranannya sebagai Back-End harus dapat diakses melalui internet, dapat menerima request dari client dan merespon kembali ke client. Kondisi tersebut juga diimplementasikan dalam melakukan operasi CRUD [12] [6].Rodrıguez dkk menekankan bahwa terdapat batasan-batasan dalam membangun sebuah RESTFul, antara lain: tidak ada nama CRUD di URL (http://{domain}/add/mahasiswa namun http://{domain}/mahasiswa) dan tidak ada transparansi teknologi yang diimplementasikan pada sisi server seperti ekstensi bahasa pemrograman (http://{domain}/mahasiswa.php/ namun http://{domain}/mahasiswa/) [9].…”

Automated scalability testing of software as a service

“…Finally, to support the easy interaction with software systems provided as a service on the Web, our Scalability Explorer was built as part of the Rehearsal [21] testing framework, which provides facilities to simplify tests of web services. It includes a dynamic web service client, a proxy to intercept messages for evaluation and a web service mocking component.…”
