Now I need get 1 random link from usefull links on my page Methodology.
And the condition is that the name of random transaction should be gotten from relative URL of this transaction, like this:
"random_link_relative_URL" = "/index.php/What_are_the_Goals_of_Performance_Testing?"
The code for this case is next:
Action()
{
lr_start_transaction("open index page");
web_url("***",
"URL=http://{HOST}/",
"Resource=0",
"RecContentType=text/html",
"Referer=",
"Snapshot=t19.inf",
"Mode=HTML",
LAST);
lr_end_transaction("open index page",LR_AUTO);
/* in link_name we are collecting elements of links array on Methodology page*/
/* in my case usefull links have the structure like this:
<p><a href="/index.php/Load_Testing_Terminology" title="Load Testing Terminology">Load Testing Terminology</a>
and useless links have different HTML-code structure,
therefore we need to use LB and RB to limit useful HTML snippets like this:
/index.php/What_are_the_Goals_of_Performance_Testing */
web_reg_save_param("link_relative_URL", "LB/ic=<p><a href=\"", "RB=\" title", "ORD=all", LAST );
/* the array containing 21 items of link_relative_URL is created when the transaction Methodology is performed */
lr_start_transaction("Methodology");
web_url("Methodology",
"URL=http://{HOST}/index.php/Methodology",
"Resource=0",
"RecContentType=text/html",
"Referer=http://***/index.php",
"Snapshot=t20.inf",
"Mode=HTML",
LAST);
lr_end_transaction("Methodology",LR_AUTO);
/* using `lr_paramarr_random` function we can choise 1 random link from array of link_relative_URL and save this random link from array to parameter colled random_link_relative_URL */
lr_save_string(lr_paramarr_random("link_relative_URL"),"random_link_relative_URL");
/* let's verify that {random_link_relative_URL} was saved */
`lr_output_message("random link is %s",lr_eval_string("{random_link_relative_URL}"));`
/* let's save the relative URL `random_link_relative_URL` to variable colled `random_link_name` */
sprintf(random_link_name, lr_eval_string("{random_link_relative_URL}"));
/* start transaction random_link_name */
lr_start_transaction(random_link_name);
/* using this sintax we will see the name of random link in requst's status */
web_url(lr_eval_string("{random_link_relative_URL}"),
"URL=http://{HOST}{random_link_relative_URL}",
"Resource=0",
"RecContentType=text/html",
"Referer=http://{HOST}/index.php/Methodology",
"Mode=HTML",
LAST);
/* close transaction */
lr_end_transaction(random_link_name, LR_AUTO);
return 0;
}
On the 1st step we will see the array of usefull links on Methodology page, on the 2nd - chosen random link, and on the 3rd - transaction which has name and URL of this random link.
The 2nd way.
Action()
{
lr_start_transaction("open index page");
web_url("***",
"URL=http://{HOST}/",
"Resource=0",
"RecContentType=text/html",
"Referer=",
"Snapshot=t19.inf",
"Mode=HTML",
LAST);
lr_end_transaction("open index page",LR_AUTO);
/* saves pages names as link_name on Methodology web page using limitations in HTML tag */
web_reg_save_param("link_name", "LB/ic=<a href=\"/index.php/", "RB=\" title", "ORD=ALL", LAST );
lr_start_transaction("Methodology");
web_url("Methodology",
"URL=http://{HOST}/index.php/Methodology",
"Resource=0",
"RecContentType=text/html",
"Referer=http://***/index.php",
"Snapshot=t20.inf",
"Mode=HTML",
LAST);
lr_end_transaction("Methodology",LR_AUTO);
/* select random link from links array on the page Methodology */
random_tr = lr_paramarr_random("link_name");
return 0;
}
The way to solve this task may be next:
in Action section to write only 1 request with 2 parameters {name_of_random_link}
and {URL_of_random_link}
:
web_url("{name_of_random_link}",
"URL={URL_of_random_link}",
"Resource=0",
"RecContentType=text/html",
"Referer=http://***/Methodology",
"Mode=HTML",
LAST);
The list containing 20 strings of 2 related parameters {name_of_random_link}
and {URL_of_random_link}
is placed in parameters list file.
{name_of_random_link}
is randomly selected from this list and {URL_of_random_link}
is selected as "the same line as URL_of_random_link".
