The Design And Implementation Of Part Modules Of Cloud Test Service Providing Paas

Cloud Computing is the current leading information technology. In the Cloud Computing, both the software and the hardware are abstracted into resources and encapsulated as Service for outside, making the IT infrastructure to be simplified and optimizing the allocation of resource. Combining the cloud computing with software testing, make the cloud computing as an emerging applying in the field of it. Through the cloud testing, not only can improve the testing efficiency, reduce test time, you can also simplify the test steps and make the testers free from the finicky testing work which includes complex test resource management, test environment and script maintenance.With the continuous development of cloud computing, the research and development of cloud testing technology has drawn increasing attention, some typical applications of cloud testing haven developed in the field of both software and hardware.The research of this paper is the application of cloud testing in the field of software. In this paper, the realization of Cloud Test Service (CTS in short) platform cloud system is in this context. By using the Eucalyptus private cloud framework to integrate the underlying hardware resources, CTS system has its own unified modules to manage and schedule virtual instances offered by Eucalyptus. By providing a series of service interface and defining a specified standard to achieve the goal of Platform as a Service. Also CTS system provides a friendly and easy using Web User Interface. The test developers can customize the Test Services which they needed, and then upload to CTS platform cloud, thus the Test Services have been registered to CTS system.This paper focuses on the CTS platform cloud implementation, and introduces some technology concepts of the clouds testing. And giving the detail design of the CTS system architecture and each module, then describe the implementation of Extensive Engine Module, Instance Management and Instance Scheduler Module in details. In the end of this paper, a summary and prospects in the next step have been done.
