This document discusses HP LoadRunner, a performance testing tool. It provides an overview of LoadRunner, including what performance testing is, the types of performance testing, limitations of manual testing, LoadRunner components, designing and executing scenarios, and analyzing results. The key points are that LoadRunner automates performance testing by using virtual users to simulate real user loads and measure system behavior, components include VuGen, Controller, and Load Generators, and it allows designing, running, and analyzing load testing scenarios to evaluate system performance.

- 3. PERFORMANCE TESTING WHAT? A non-functional testing technique Determines the system parameters in terms of responsiveness, speed, stability, throughput and reliability under various workload Uncovers what needs to be improved before the product goes to market WHY? Does the application respond quick enough on several users? Does it meet client requirements Will it bear expected user load or beyond load? Search results example WHICH? Always done for client server based systems only
- 4. TYPES OF PERFORMANCE TESTING LOAD TESTING - measures the system performance based on a volume of users. STRESS TESTING – measures application under extreme workloads, measure the breakpoint of a system ENDURANCE TESTING – measures application can handle the expected load over a long period of time. SPIKE TESTING – measures how the system behaves under unexpected heavy load conditions, and its ability to recover. VOLUME TESTING – measures performance under varying database volumes SCALABILIT TESTING - measures the software application's effectiveness in "scaling up" to support an increase in user load. Helps plan capacity addition to your software system.
- 5. MANUAL TESTING LIMITATIONS Expensive Time consuming Not Availability of man power and machinery Complicated in terms of Concurrency Inaccurate or probabilistic results

- 9. LOADRUNNER? An automated solution by HP now Micro focus. Founded in April 2000 Latest version 12.55 Replaces human users with virtual users (Vusers) Creates peak and controlled load situations Reduces hardware requirements Controls from a single component
- 10. LR COMPONENTS VUGEN Records and edits Vuser scripts CONTROLLER An administrative center for creating, maintaining, and executing Scenarios LOAD GENERATOR Generates the load against the application by following scripts ANALYSIS Assembles logs from various load generators and formats reports for visualization of run result data and monitoring data.
