    1) Select the load Runner from the Start menu.
    2) From the Load testing Tab, click on "Create/Edit Scripts"
    3) Once the Virtual User generator is opened, select "New" and select the protocol based on your project requirement or for a sample application select "Web(HTML/HTTP)" protocol from the Available protocols and click "ok"
    4) Enter the URL of the application which you are going to test.
    5) Give the Working Directory path in which your script need to be saved.
    6) In Record to Action you have three options
    i) vuser_init -> record the login part
    ii) Action -> record the transaction or the body part.
    iii) vuser_end -> record the sign off
    Note: for your sample login to action and record all the script.
    7) Once the url is opened start entering the username and password and do the other transaction process. Once finish, log off and stop the record session by click the stop icon.
    8) Correlate the script, parameterize the URL, username and password if required other variables too and check whether the the script runs without any errors
    Note: Before running check the run time settings and run for atleast three to five iterations.
    9) Create more scripts according to your requirement and check they should run without errors.
    10) Open the scenario, pull all the scripts add the number of users you want to run, set the rampup and duration of the run. Runtime settings and Generators you are using to run the load should be given. see that you connected the generators and Start running the scenario.
    11) Analyse the graph for the performance.

    Dear Friend, I hope you have Completly understand the Application Business Process you will be testing. Secondly you have better Understanding on the  Infrastructure Architecture you will be Testing and the application would be deployed. Thirdly you should have the informathion on WorkLoad that the test needs (Business process  to test, Transactions to Achieve, TPS to achieve, Goal Oriented or Transaction Oriented ). These things are Important before you start the Planning/Statergy document as you will have to document all these in the statergy document.

    The Plan and Statergy doc includes
    Introduction.
    Short Description of the application.
    What is the objective of the testing.
    Distribution List.
    Inscope/Outscope of the test.
    Test Mix/Scenraios.
    Business Process Identified (Document with Click  Stream, VUgen will generate BP document).
    Attach Document of the Infrastructure configuration of your test environment (You can get it from your IT team).
    Test tentative Schedule.
    Description of the Tests you would perform, Like Average Load, Peak Load, Scalability, Soak etc.

    If you are still in req Gathering you can identify the Business process and give it to your stake holder that we have identified these process for testing.

    Next you can get the Work Load, what is the expected User load they are expecting Peak and Non Peak, then prepare a work load metrix.

    Hi Vivek,

    1.)Is the same script runs 100 times for same UID/PWD what i have entered during Recording

    Ans - Yes the same script is running.

    2.)If my data base contains only 50 users.Selecting 100 Vusers is a valid case?.

    Ans - Yes it is a valid case because it id not going to your DB to fetch records as it is only generating the load.

    If you want to login as 100 different users then you have to paramterize the script and then pass 100 users in an excel.

    3.)If i have selected 100 Vusers,is it necessary to enter 100 UID/PWD.
    Ans - No it is not necessary.

    Vivek it is a better practice that for any specific role(User Type) you may put the data in an XLS and then call that XLS in the program. This will imitate a real life condition.

    Answered by: ramesh viswanathan

    • Dec 23rd, 2005


    Loadrunner cannot monitor, but the component in Loadrunner namely controller helps ur query.

    You need to have proper licenses for monitoring the servers be it either web, app or db server.

    Default u can monitor windows resources u do not need to have any license for this. If perfmon is available in your workstation. This feature in controller calls the perfmon dll and counters can be added to monitor the behavior of the whatever windows workstation that is needed.
