PLeTsPerf - A Model-Based Performance Testing Tool

Performance testing is a highly specialized task, since it requires that a performance engineer knows the application to be tested, its usage profile, and the infrastructure where it will execute. Moreover, it requires that testing teams expend a considerable effort and time on its automation. In this paper, we present the PLeTsPerf, a model-based performance testing tool to support the automatic generation of scenarios and scripts from application models. PLetsPerf is a mature tool, developed in collaboration with an IT company, which has been used in several works, experimental studies and pilot studies. We present an example of use to demonstrate the process of generating test scripts and scenarios from UML models to test a Web application. We also present the lessons learned and discuss our conclusions about the use of the tool.
