What is the use of ITOA?

itoa () function is used to convert int data type to string data type in C language.

What is Atoi in LoadRunner?

‘atoi’ function converts a string to an integer value.

What is Lr_save_string in LoadRunner?

you use lr_save_string to convert c string to loadrunner string. If you declare order no in C and use it in your web function, it will not work, in order to work, you need to convert C string to LR string.

What is the use of Web_set_sockets_option?

The web_set_sockets_option function configures options for sockets on the client machine. This function supports socket-level replay. In the Web HTML protocol, it supports both HTML-based scripts (Mode=HTML) and URL-based scripts(Mode=HTTP modes).

What is parameterization and correlation in LoadRunner?

Correlation is done for the dynamic value or the value returned by server for any request. Parameterization differs from correlation in a way that former takes care of user input data whereas later takes care of data returned by server.

Why parameterization is necessary in performance testing?

Parameterization is the technique using which we can execute a test plan multiple times with a different sets of data. This helps in creating a load test script that closely simulated real-world scenarios where different users use different test data.

What is vugen in LoadRunner?

What is VUGen? VUGen (Virtual User Generator) is a key tool in LoadRunner to create testing scripts to emulate real-user behavior on your system. In VUGen, a human is replaced by a virtual user (VUser) and the actions performed by a VUser are recorded in VUser script to emulate the real-user behavior for testing and monitoring.

What is ITOA () function in C++?

The itoa () function constructs a string representation of an integer. Is the integer to be converted to string representation. Points to the buffer that is to hold resulting string. The resulting string may be as long as seventeen bytes. Is the base of the number; must be in the range 2 – 36.

What are the different LoadRunner functions?

These functions are the general LoadRunner functions that are common for all protocols: 1) lr_eval_string (): As already seen, this function returns the input string after evaluating any embedded parameters. 2) lr_eval_string_ext (): This function creates a buffer and assigns it to the input string after evaluating the embedded parameters.

What is a loop in vugen?

Posted on Nov, 2009 by Admin Most people who use Vugen and have a development background know loops. In C or most other programming languages, a loop is a loop. Sometimes in my classes I will ask students the main difference between a “do while” loop verses a “while” loop to see if they have that programming background.
