There can not be any generic value for Vuser. What is the difference in running the Vuser as a process and as a thread? Which is more advantageous way of running Vuser? When Vuser is run as a process the same driver program is loaded into memory for each Vuser. This will take a large amount of memory and will limit the number of Vusers you can run on a single generator When Vuser is run as a thread, only one instance of driver program is shared by given number of Vusers.

Vuser- init records the pre- operations also called the initialization operations before the actual application is run. What is extended log? An extended log will store information such as data returned by server and advanced trace, parameter substitution and much other information depending on the options you select in run- time settings. Why do you create parameter? To create a parameter you will replace the hard coded value within the script and replace it with a parameter. It helps in stimulating more real life server demand as it prevents server from caching results.

I will divide the script into Actions based on the functionality. For example, Once Action for Logining into Application, another Action for booking and so on. How can you set the number of Vusers in Loadrunner ? You can set the number of Vusers in the controller section while creating your scenarios. Many other advanced options like ramp- up, ramp- down of Vusers are also available in the Controller section. They are used in Controller section of Load Runner 1.

What are the types of check points is available in Load. Runner? Loadrunner provides two types of check points a) Image Checkpoints : This checkpoint will verify the presence of an image on a page during run- time b) Text Checkpoint : This checkpoint will verify the presence of a text- string on a page during run- time Both of the above checkpoints can be added in Vugen.

You may also optimize your database queries. What is Rendezvous point? Rendezvous points instruct Vusers to wait during test execution for multiple Vusers to arrive at a certain point, in order that they may simultaneously perform a task. What is Correlation? Correlation is used to obtain data which is unique for each run of your test script (ex: session ids).

While recording, these dynamic values are hard- coded in your script causing the script to fail during playback. Correlation is a technique where dynamic values are not hard- coded in your script but are extracted at run- time to avoid failure. Learn more about Correlation in this video tutorial. What is Manual Correlation?

Its correlation technique which uses function Web. How do you identify the performance bottlenecks? The function is -  lr.

What is the difference between transaction and transaction instance in loadrunner ? A transaction is used to measure time between executions of certain statements A transaction instance is used for performance analysis 2. While the script is running we find some values that may be need to be correlated? Is it possible to do manual correlation for those values? Its not possible to do correlation when script is running but you can make changes once script has stopped. What is Elapsed Time in Load Runner? Elapsed time designates how much time has passed since the launch of the current event and is measured differently for different screens as given below - In Scenario Status Window - Elapsed time is measured from the moment you hit .

Does caching have a negative effect on your load testing results ? Caching has a negative effect. Cache is temporary memory which stores your browsing history. When you visit a page for the SECOND time , the time required to load the page will be less than that required to load the page for your first visit since much of the information required to load the page is grabbed from the cache instead of the server. This will effect the response times in your test.

Hence, it is recommended to turn- off caching. What is the difference between Overlay graph and Correlate graph? Overlay Graph: It will overlay the content of two graphs that shares a common x- axis Correlate Graph: It will Plot the Y- axis of two graphs against each other. The objective of performance testing is to check whether an application loads/updates  within stipulate time limit (say 2 seconds). It uses metrics like response time , Requests per second. It is carried out under production - like load conditions.

For example, finding out the maximum number of users supported by the system within certain specifications. You have created several  Auto Correlation rules.

A new tester on your team is preparing to record a group of scripts on the same application on his workstation. What can you do to provide the tester with the correlation rules?

After the demo period, we need to purchase one of the licenses so as to continue working with the tool. There are two types of license, Seat and Concurrent License. Seat License. It’s a license that is specific to the computer on which the tool is installed i. This license is installed on a remote license server. Hence a particular number of users can work with the tool by connecting to the license server at the same time; the number varies based on the number of concurrent licenses purchased. There is a sub type of concurrent license called commuter license. It is a concurrent license that works like a seat license for a given time period.

The validity period is usually 1. Let’s assume we have configured 1. In such instances, we can ask administrator to configure commuter license.

This works like a seat license for a given time period. Thus for this specific time period, the concurrent licenses available offshore will be equal to total concurrent licenses minus commuter licenses. Read about UFT licenses in detail. UFT Cost.

A Raw Example Where UFT can be Used. Let’s consider the scenario where you want to test login for a particular user. To test this scenario manually, you would generally follow these steps –Open web browser. Enter the URL of the application. Enter user id & password and then click on “Login” button on login page.

Verify that login is successful. Now consider a case where you have to test this login functionality many a times or you have to test the same functionality for large number of different users say a 1. Performing this action manually is time consuming & tiresome activity. Now UFT helps you replicate your actions that you do manually such as opening the application, entering user id and password and hitting the “Login” or “Submit” button and verifying whether or not you have logged in successfully. To achieve this, you can write your code for log in scenario in UFT and run the code any number of times with a single click of a button, of course with same or different test data as required. This is a very raw example, in trained hands UFT can accomplish a lot many tasks. As of August 2. 01.
