We can use this function in two ways with run time settings in loadrunner and with lr_set_debug_message.
Example 1: Set extended log in run time settings(F4)->Log->Extended Log->Data Returned by Server.

Now I have recorded Facebook.com and used lr_debug_message.

If the extended log is enabled it will print the message "I Love Facebook" else it will ignore the message. It will not print any message if the extended log is not enabled.

lr_debug_message(LR_MSG_CLASS_EXTENDED_LOG, "I Love Facebook");

web_url("www.facebook.com",
"URL=http://www.facebook.com/",
"Resource=0",
"RecContentType=text/html",
"Referer=",
"Snapshot=t1.inf",
"Mode=HTML",
LAST);
Example 2: With lr_set_debug_message In this example I have used lr_set_debug_message with lr_debug_message as shown in the following example. It will print the message "I Love Facebook" if lr_set_debug_message is written else it will ignore. Try…

By using this function we can save the current date, time, day, hour, and minute into parameter. We have the following predefined constants that we can use with the function:

DATE_NOW, TIME_NOW, ONE_DAY, ONE_HOUR, ONE_MIN.

It evaluates a parameter and after evaluating the parameter it replaces the parameter with its current value.

You cannot place lr_eval_string in the middle of the web functions or any other functions. You can directly use in the web functions like this {URL}. It will replace the parameter with its current value.

Lr_save_int is same as lr_save_string it converts an integer to string and saves in a parameter.

Example 1:

In this example I have declared value=10 and save in the URL using lr_save_int.

we use lr_save_string mainly to convert a string to parameter and use that parameter wherever required.

Example 1:

In this example I have saved my website name in a string a[] and I converted the string to parameter using lr save string and I used URL in web_url function as shown below.

In this post I will explain how to capture a value from server response and save to a text file using vugen.
How to capture and save to text file using loadrunner:
First I have recorded the script using bing.com and then i searched for IBM. We will get 10 results. I have captured all the 10 values and saved to a file.
Here is the code for that.

1. Generation LogOne of the common options in loadrunner is generation log. You will take the left and right boundary and search in the generation log and use CTRL+F and find the request name and place the web_reg_save_param before that request.
2. Replay LogSometime you do not find correlation value in generation log than the alternative way is go to run time settings and click on Log->Extended Log-> "Data Returned by Server" option and replay the script. Once you replay the script you will use CTRL+F and find the left and right boundaries. Sometimes replay log may fail or it will take a long time if you select “data returned by server” as it is printing all the response to the replay log then the alternate method to use is  lr_set_debug_message as shown in this link.
3. RedirectionIf you are not able to find the value in generation log and replay log then there might be 301 or 302 redirection.  Find out the pages that have 301 or 302 redirection. Once you find the page…

Hello, looking for interview questions in loadrunner? I have tried my level best to put these interview questions. If you find any new questions, you can always send me through the comments below.

Web Services in loadrunner: We can do web services scripting in two ways:
By using Web Services Protocol. (Need additional License)By using Web Protocol. Scripting using Web Services Protocol: I have taken weather web service as example shown in this link.
Steps: First open the vugen and select Web Services protocol.Click on Manage Services on top nav bar and Click on Import and give the WSDL URL which is usually ends with wsdl http://www.webservicex.net/globalweather.asmx?WSDL.
Now Click on Add Web Service Call on top nav bar. Give the Input Arguments and Leave the out put arguments empty. And click on ok. As shown in the following image.
It will create a script in loadrunner as shown below. You can perform the steps one by one in this way for all the web services steps. You can use lr_xml_find and lr_xml_get_values to validate the page.
web_service_call( "StepName=GetCitiesByCountry_101",
"SOAPMethod=GlobalWeather|GlobalWeatherSoap|GetCitiesByCountry",
"ResponsePa…
