A Research Of Parallel Test Generationbasedon The Scene Of The Web Service Combination

With the rapid development of information technology. Requirements for quality of Web services is increasing, range of services are more and more complex. Web service composition emerged, namely, combined the individual atoms service together according to certain rules and order, to meet customers’needs.For the combined Web service, its quality has become the most noteworthy aspect, so the Web service composition testing becomes particularly important. The main topic of this paper is the test cases generation based on the scenarios of Web service combination. The high-quality test case can detect weather the function of Web service combination can meet the needs of Web users.At the same time, taking into account a combination of Web services will generate a huge number of test cases, and the process of generate the test cases are independent from each other, so the process can be achieved by the Mapreduce framework of Hadoop platform, thereby improving the efficiency of test case generation.In summary, this paper work done in the following section:1. Sequence diagram models are established based on scenarios of Web service combination;2. An algorithm of generating control flow graph form sequence diagram models is proposed;3. An algorithm of generating test cases of Web service combination is proposed;4. Build Hadoop experimental environment, generate and execute test cases on a cloud platform, test cases are verified feasibility and efficiency.
