[Abstract]:With the continuous development of Internet application technology, the information service mode of Internet-based application system has been widely used in various industries. The constant development of informatization has brought fundamental changes to our life, mode of production and business model. The development of the Internet brings development opportunities to Internet application enterprises and also brings technical challenges. More Internet applications will face the technical test of high concurrent access with a daily average of over 100 million visits. At the same time, it also brings unprecedented challenges to software quality assurance. The traditional performance testing tool is to simulate the local virtual user to send the service request to the server through the pressure controller, and simulate the stress test of the server. The generation of the load pressure is all through the physical host in the local area network. For a general Web application system, the number of virtual concurrent users is in the order of hundreds of thousands, the traditional performance tools can meet the needs of applications, but for tens of thousands or more of application services, the traditional performance testing tools can no longer meet the requirements. In this case, new problems arise in software performance testing: (1) the number of massive users can not be simulated; (2) the client side of the application is extremely widely distributed. Tools can not traverse complex access paths to obtain real user experience. (3) it can not monitor the resource performance of heterogeneous cloud computing platform. In the last two years, cloud computing platform has landed in various parts of the country, which provides an opportunity to realize high concurrent virtual user simulation based on Internet, which is restricted by the test environment of traditional performance testing tools, and makes use of cloud computing resources. It provides a test environment for high concurrency testing and effectively solves the problem that high concurrency virtual user can not simulate. Based on the above background, this paper proposes a tool to develop high concurrent performance testing using cloud computing resources, to solve the problem of virtual user simulation, and to use the existing cloud computing resources in China to provide high concurrent performance testing services for software enterprises. This paper first investigates the technology and tool foundation of cloud performance testing tools, puts forward the cloud resource requirements for cloud performance testing tools, and analyzes the problems existing in traditional performance testing tools. Aiming at the problems, this paper puts forward the main goal and specific functional requirements of cloud performance testing tools, expounds the key technical problems of tool working mechanism, processing flow and design and implementation, and completes script recording and pressure generation in this technology. Design and implementation of pressure generation control, system monitoring, result analysis and other functions. At the same time, this paper focuses on the design principle of the key technologies of remote job scheduling and control synchronization, data cache and verification of test results and performance monitoring of computing resources on heterogeneous cloud platform, and builds a simulated test environment. Verification tool can achieve 100000 virtual user simulation concurrency.
