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.

  • 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

Introduction

  • Define VuGen

Replay

  • Identify and configure the appropriate web runtime setting for replay
  • Replay the script in VuGen to verify script functionality
  • Recognize the debugging tools available in VuGen

Transactions

  • Explain the function of a transaction in a script
  • Insert a transaction in a script during and after recording

Parameters

  • Explain what parameters are and how they work

Manual Correlation

  • Determine when manual correlation is required
  • Correlate dynamic values using the create parameter option

Auto Correlation During Recording

  • Create correlation rules to auto correlate during recording
  • Import and export correlation rules

Introduction to Scenarios

  • Explain elements that make a LoadRunner scenario
  • Identify different types of scenarios
  • How to choose the scenario
  • Present the basic steps for creating a scenario

Scenario Execution

  • Prepare for a scenario run
  • Identify techniques to efficiently run a scenario

Scheduling Scenarios

  • Scheduling by group and by scenario
  • Prepare VuGen User (Vuser) initialization
  • Configure duration scheduling
  • Configure scenario ramp up and ramp down

Performance Monitors

  • Value of Performance Monitors
  • Select Performance Monitors
  • Add measurements to Performance Monitors

Results Analysis
