The Power of LoadRunner

To illustrate the power of LoadRunner, you will run and analyze a load test

against a database application, with up to 10 concurrent users. The test will

emulate travel agents simultaneously using the flight reservation system (for

example, logging on, searching flights, purchasing flights, checking

itineraries, and logging off).

During the test, you will observe how the Web server behaves under load

usingLoadRunner’s online monitors. In particular, you will see how an

increase in load affects the time that it takes the server to respond to a user

action (transaction response time) and causes errors.

After you have seen how LoadRunner can be used to generate load on a

system and measure the responsiveness of the system to that load, you will

learn how to use the LoadRunner components—VuGen, Controller, and

Analysis—to create and run your own test, and analyze test results.

Note: LoadRunner allows you to purchase a license to use as many virtual

users (Vusers) as you need to effectively test your application. For the

purposes of this LoadRunner trial version, however, you are licensed to use

25 Vusers only.

Creating the Load Test

The Controller is the central console from which you build, manage, and

monitor your test. You will use the Controller to run a sample script that

emulates the actions performed by a real user, and create load on the system

by having a number of virtual users concurrently perform these actions.

1 Open the HP LoadRunner window.

Choose Start > Programs >LoadRunner>LoadRunner. The HP LoadRunner

Launcher window opens.

Running the Load Test

Click the Start Scenario button. The Controller run view is displayed, and

the Controller begins the scenario.

In the Scenario Groups pane, you can see as Vusers gradually start to run

and generate load on the system. You can see the responsiveness of the

server to the Vuser actions in the online graphs
