A string that uses {} By default in Vugen is called a parameter

Note: The parameter must be in double quotation marks in order to use

To save a string as a parameter

Lr_save_string ("String want to Save", "Arg_name");

Example: Replacing a URL link that needs to be opened with a parameter

Action2 ()

{

Lr_save_string ("http://172.25.75.2:1080/WebTours/", "Web_site");

Open the login page

Web_url ("Webtours",

"URL = {Web_site}",//Run error//change to "url= {web_site}"

"Resource=0",

"Reccontenttype=text/html",

"Referer=",

"Snapshot=t1.inf",

"Mode=html",

last);

return 0;

}

Operation Error:

ACTION2.C (6): error-27226:the "URL = http://172.25.75.2:1080/WebTours/" argument (number 2) is unrecognized or misplaced [msgid:merr-27226]

ACTION2.C (6): Web_url ("webtours") highest severity level was "ERROR", 0 body bytes, 0 header bytes [msgid:mmsg-26388]

Workaround:

"url = {Web_site}", there is a space between the URL and the equal sign "=", the space can be removed.

So using the lr_eval_string () function is also called using double quotes.

You can also do this in the following way

Action2 ()

{

Lr_save_string ("http://172.25.75.2:1080/", "Web_site");

Lr_save_string ("webtours/", "web_name");

Open the login page

Web_url ("Webtours",

"Url={web_site}{web_name}",

"Resource=0",

"Reccontenttype=text/html",

"Referer=",

"Snapshot=t1.inf",

"Mode=html",

last);

return 0;

}

Gets the string table of the parameter value

You can use the Lr_eval_string function to get a string representation of a parameter value and then output the result using the Lr_output_message () function

Action2 ()

{

Lr_save_string ("http://172.25.75.2:1080/", "Web_site");

Lr_save_string ("webtours/", "web_name");

Lr_output_message (Lr_eval_string ("Get string representation of parameter value: {web_site}{web_name}"));

Open the login page

Web_url ("Webtours",

"Url= {web_site}{web_name}",

"Resource=0",

"Reccontenttype=text/html",

"Referer=",

"Snapshot=t1.inf",

"Mode=html",

last);

return 0;

}

Note: If you want to get the first letter of the argument string, the same as C, you can: Lr_eval_string ("{param}") [0];

will be int type numbers are saved as parameters

Lr_save_int (Int_number, "Param_name")

For example:

Action2 ()

{

Lr_save_int (0, "Int_param");

Open the login page

Web_url ("Webtours",

"Url=http://172.25.75.2:1080/webtours/",

"Resource=0",

"Resource={int_parma}",

"Reccontenttype=text/html",

"Referer=",

"Snapshot=t1.inf",

"Mode=html",

last);

return 0;

}

Save the time as a parameter

Implemented by the Lr_save_datetime function.

Function Prototypes:

void Lr_save_datetime (const char *format, int offset, const char *name);

Format: Expected output date formats, such as:%Y,%m,%d,%x, etc.

Offset: Similar to some keyword constants that represent time:

Date_now-now date

Time_now-Now time

One_day-day time

One_hour-One Hour time

One_min-A-minute time

It is important to note that they can be used alone or in conjunction with

Current time Date_now + Time_now

Date_now-one_day, yesterday

Date_now+one_day-Tomorrow

Two days before the date

date_now-2* (One_day), date_now-2*24* (One_hour), date_now-2*24*60* (one_min)

2 hours after the time

time_now+2* (One_hour)

time_now+2*60* (One_min)

Name: Names of the parameters that you expect to save time to

Lr_save_datetime ("%y-%m-%d%x", Date_now+time_now, "datetime");

Lr_save_datetime ("%y-%m-%d", Date_now-one_day, "Yesterday");

Lr_output_message (the current time of the system is: {lr_eval_string));

Lr_output_message (lr_eval_string (the current date of the system is: {date}));

Lr_output_message (lr_eval_string ("Current date of the system, current time: {datetime}");

Lr_output_message (Lr_eval_string ("Yesterday's date: {yesterday}"));

return 0;

}

Operation Result:

ACTION.C (7): The current time of the system is: 12:27:54

ACTION.C (8): The current date of the system is: 2014-10-22

ACTION.C (9): current date of the system, current time: 2014-10-22 12:27:54

ACTION.C (10): Yesterday's date is: 2014-10-21

Ending action action.

Ending Iteration 1.

Save the content as a formatted parameter

lr_param_sprintf (Param_name,format,var1,var2,...);

Example:

Action2 ()

{

int index = 56;

Char *suffix = "txt";

lr_param_sprintf ("Newparam", "log_%d.%s", Index,suffix);

Lr_output_message ("The new file name is%s", lr_eval_string ("{Newparam}"));

return 0;

}

Operation Result:

Starting action Action2.

ACTION2.C: The new file name is Log_56.txt

Ending action Action2.

Save the contents to the parameter array

This concept lr9.x only after

The array of parameters must meet the following two conditions:

1. The parameters must be assigned in the order of the same name, followed by an underscore and a number.

2. The parameter array must have a parameter named _count to record the length of the array

Related functions:

LR_PARAMARR_IDX ()//Gets the value of the specified number parameter in the parameter array

Lr_paramarr_len ()//Get the length of the parameter array

Lr_paramarr_random ()//Get a random parameter from the parameter list

Example: To create an array of parameters to access a Web site, you can write the following code

Script development-parameterization to save content as parameters, parameter arrays, and parameter values get "title=" LoadRunner script development-parameterization to save content as parameters, parameter arrays, and parameter values get "border=" 0 ">

Description: A parameter array named website was created with a script, and the value of the parameter with number 2 was obtained.

Operation Result:

Script development-parameterization to save content as parameters, parameter arrays, and parameter values get "title=" LoadRunner script development-parameterization to save content as parameters, parameter arrays, and parameter values get "border=" 0 ">

Here: web_site= lr_paramarr_idx ("website", 2), equivalent: Lr_eval_string ("{website_2}");

Get parameter array length

Example:

Action2 ()

{

intarray_size = 0;

Char*arr_size_str = NULL;

Lr_save_string ("www.google.com", "website_1");

Lr_save_string ("www.google.com", "website_2");

Lr_save_string ("www.google.com", "website_3");

Lr_save_string ("www.google.com", "website_4");

Lr_save_string ("4", "Website_count");

Array_size = Lr_paramarr_len ("website");

Output integer

1. Save the result array_size as a parameter

Lr_save_int (Array_size, "arr_size");

2. Get the string representation of a parameter

Arr_size_str = Lr_eval_string ("{arr_size}");

Output results

Lr_output_message (ARR_SIZE_STR);

return 0;

}

Operation Result:

Script development-parameterization to save content as parameters, parameter arrays, and parameter values get "title=" LoadRunner script development-parameterization to save content as parameters, parameter arrays, and parameter values get "border=" 0 ">

Get a random parameter from the parameter list

Example:

Action2 ()

{

Char*web_site = NULL;

Lr_save_string ("www.google.com", "website_1");

Lr_save_string ("www.google.com", "website_2");

Lr_save_string ("www.google.com", "website_3");

Lr_save_string ("www.google.com", "website_4");

Lr_save_string ("4", "Website_count");

Web_site = Lr_paramarr_idx ("website", 2);

return 0;

}

Operation Result:

Script development-parameterization to save content as parameters, parameter arrays, and parameter values get "title=" LoadRunner script development-parameterization to save content as parameters, parameter arrays, and parameter values get "border=" 0 ">

Example: output each parameter sequentially

Action2 ()

{

int i= 0;

Lr_save_string ("www.google.com", "website_1");

Lr_save_string ("www.google.com", "website_2");

Lr_save_string ("www.google.com", "website_3");

Lr_save_string ("www.google.com", "website_4");

Lr_save_string ("4", "Website_count");

for (i=0; i

{

Lr_output_message (Lr_paramarr_idx ("website", I));

}

return 0;

}

Output results

Script development-parameterization to save content as parameters, parameter arrays, and parameter values get "title=" LoadRunner script development-parameterization to save content as parameters, parameter arrays, and parameter values get "border=" 0 ">

Storing parameters with pointer variables

Action2 ()

{

Char*pt = NULL;

Lr_save_string ("Hello World", "Param");

pt = "{param}";

Lr_output_message (PT);

Lr_output_message (Lr_eval_string (PT));

return 0;

}

Operation Result:

Script development-parameterization to save content as parameters, parameter arrays, and parameter values get "title=" LoadRunner script development-parameterization to save content as parameters, parameter arrays, and parameter values get "border=" 0 ">

LoadRunner script Development-parameterization to save content as parameters, parameter arrays, and parameter values get
