  • View performance test result

  • Merge graphs

Steps to do performance test in HP load runner

• • .Generate requirement and plan test

  • Generate Vuser script

  • Setup the Scenario using the controller

  • Run the scenario using controller

  • Analyze the result, review the result and compare with the requirements
