A Model-Based Performance Testing Toolset for Web Applications

Abstract- Effective performance testing techniques are essential for understanding whether a Web-based application will meet its performance objectives when deployed in the real world. The workload of such an application has to be characterized in terms of sessions; a session being a sequence of inter-dependent requests submitted by a single user. Dependencies arise because some requests depend on the responses of earlier requests in a session. To exercise application functions in a representative manner, these dependencies should be reflected in the synthetic workloads used to test Web-based applications. The need to handle these dependencies makes performance testing a time consuming process. Specifically, since the nature of these dependencies varies across systems considerable effort needs to be dedicated towards tailoring a set of test tools that will work for a give
