Advanced IBM Rational Performance Tester

Course Summary

This advanced course is designed to enhance a student's knowledge of the performance testing lifecycle using IBM Rational Performance Tester. Web-based applications are the focus of the class, during which students are provided insight into the architecture of web-based applications, implications upon test planning, automation, execution, and analysis. The course includes lecture and classroom discussion, with an emphasis on student exercises and labs applicable to real-world web applications and challenges. Extensive data correlation and parameterization techniques are addressed in the context of standard web clients, rich web clients, and desktop web clients. The course will require extensive Java programming in order to address the needs of business process automation and its requirements to properly model an application's end-user experience.
