HP LoadRunner is a load testing product that determines application scalability, behavior, and performance. It emulates thousands of virtual users, and identifies and isolates performance bottlenecks acrossand within each tier.
This course teaches students the fundamentals of performance testing using LoadRunner. By the completion of this course, students will be able to utilize LoadRunner’s features to automate performance / load tests.
Duration: 4 Days
Course Objectives
This course teaches you to:
- Discuss the value of load testing
- Plan for effective load testing
- Establish load test goals
- Run load test scenarios
- Load and overload when executing scenarios
- Analyze and interpret load test results
Prerequisites
- Knowledge of the Windows 2000 or Windows NT interface and environment
- High-level knowledge of the Web and or client/server environment
