The Functions in load Runner

Functions:-

1,

In the following example, lr_error_message sends a message to the LoadRunner output window or Application Management agent log file if the login fails. lr_abort is then invoked to abort the script.

2.

The following example uses abs to convert the integers 23 and -11 to their absolute values:

       int m = 23, n = -11;

       lr_output_message ("absolute value of %d = %d", m, abs(m));

       lr_output_message ("absolute value of %d = %d", n, abs(n));

3

In the following example, the web_add_cookie function adds a cookie with the name "client_id" to the list of cookies available to the script.

web_add_cookie ("client_id=China127B; path=/; expires=Wednesday, 09–Nov–2001 23:12:40 GMT; domain=www.cnn.com");

4

 The following example gets the time as a time_t structure and converts it to a tm structure, gmt, in Coordinated Universal Time.asctime then takes gmt and converts it to a string.

5

The following example converts the initial portion of the string, s, to a float.

double atof (const char *string); /* Explicit declaration */

vuser_init() {

     float x;
     char *s = "7.2339 by these hilts or I am a villain else";

     x = atof(s);     /* The %.2f formatting string limits the output to 2 decimal places */
     lr_output_message("%.2f", x);

     return 0;
}

Output:
vuser_init.c(11): 7.23

6

The following example converts the initial portion of the string, s, to an integer.

       int i;

       char * s = "7 dollars";

       i = atoi(s);

       lr_output_message ("Price $%d", i);

Output:
vuser_init.c(7): Price $7

Example: feof

The following example, for Windows platforms, opens a file and reads it into a buffer until feof returns true, indicating the end of the file.

To run the example, copy the file readme.txt from the installation's dat directory to the c drive, or copy another file and change the value of filename.

14.

The following example, for Windows platforms, opens a file and reads it into a buffer. ferror checks for errors on the read file stream.

15

The following example, for Windows platforms, opens a file using fopen, reads it into a buffer, and then closes it.

To run the example, copy the file readme.txt from the installation's dat directory to the c drive, or copy another file and change the value of filename.

       int count, total = 0;

       char buffer[1000];

       long file_stream;

       char * filename = "c:\\readme.txt";

       // Open the file with read access

       if ((file_stream = fopen(filename, "r")) == NULL) {

              lr_error_message ("Cannot open %s", filename);

              return -1;

       }

       // Read until end of file

       while (!feof(file_stream)) {

              // Read 1000 bytes while maintaining a running count

              count = fread(buffer, sizeof(char), 1000, file_stream);

              lr_output_message ("%3d read", count);

              // Check for file I/O errors

              if (ferror(file_stream)) {

                     lr_output_message ("Error reading file %s", filename);

              break;

              }

              total += count; // Add up actual bytes read

       }

       // Display final total

       lr_output_message ("Total number of bytes read = %d", total );

       // Close the file stream

       if (fclose(file_stream))

              lr_error_message ("Error closing file %s", filename);

Output:
Action.c(19): 1000 bytes read
Action.c(19): 1000 bytes read
...
Action.c(19): 1000 bytes read
Action.c(20): 977 read
Action.c(34): Total number of bytes read = 69977

16.

The following example opens a log file and writes the id number and group name of the Virtual User to it using fprintf.

       #ifdef unix

              char * filename = "/tmp/logfile.txt";

       #else

              char * filename = "c:\\logfile.txt";

       #endif

       long file;

       int id;

       char * groupname;

       // Create a new file

       if ((file = fopen(filename, "w+" )) == NULL) {

              lr_output_message("Unable to create %s", filename);

              return -1;

       }

       // Write the Vuser id and group to the log file

       lr_whoami(&id, &groupname, NULL);

       fprintf(file, "log file of virtual user id: %d group: %s\n", id, groupname);

       fclose(file);

Written to log file:
log file of virtual user id: -1 group: None

17.

The following example uses free to de-allocate a buffer of length 1024.

18.

The following example, for Windows platforms, opens a file and reads it into a buffer. If file errors occur during the process, goto is used to escape the enclosing loop to code which prints an error message and exits the function.

int count, total = 0;

       char buffer[1000];

       long file_stream;

       char * filename = "c:\\xyzpqi.txt";

       // Open the file with read access

       if ((file_stream = fopen(filename, "r")) == NULL)

              goto file_error;

       // Read until end of file

19.

In the following example, lr_log_message sends a message to the log file if the connection to the server fails.

char* abort="aborting...";

...

if (init() < 0) {

       lr_log_message ("login failed: %s", abort);}

       return(0);

}

20.

In the following example, lr_message sends a message if the connection to the server fails.

if (init() < 0) {

       lr_message ("login failed: %s", abort);}

return(0);

}

21,

In the following example, ID is a parameter defined in the Parameter list. The lr_next_row function advances to the next row in theID.dat file.

lr_message( "Connect to Stock Trader ID Number %s",

       lr_eval_string("{ID}") );

lr_next_row("ID.dat");

lr_message( "Connect to Stock Trader ID Number %s",

       lr_eval_string("{ID}") );

The output window shows:

Connect to Stock Trader ID Number 2347

Connect to Stock Trader ID Number 2348

22.

In this example, an Iteration Number type parameter called "iteration" was defined in VuGen. The lr_output_message function sends a message to the Load Runner Controller or the Application Mangement Admin Center indicating the current iteration number.

lr_output_message ( "We are on iteration #%s", lr_eval_string ( "{iteration}" ) );

23.

In the following example, the lr_rendezvous function sets the Meeting rendezvous point. When all users that belong to the Meeting rendezvous arrive at the rendezvous point, they perform do_transaction simultaneously.

lr_rendezvous("Meeting");
       do_transaction(); /* application dependent transaction */

24. In the following example, lr.save_data assigns a series of values to the ID parameter. This parameter is then used in an output message.

// Example array of arbitrary bytes.

byte [] b_arr = new byte[]{(byte)0x12,(byte)0x2,(byte)0x1,(byte)0x3};

// Save the array into parameter ID

lr.save_data(b_arr,"ID");

// Save the contents of the array parameter to another array

byte [] output_arr = lr.eval_data("<ID>");

lr.output_message("This is the value of the first output byte: "

       + Byte.toString(output_arr[0]));

25

In the following example, lr_load_dll is used so that a standard Windows message box can be displayed during script replay:

lr_load_dll("user32.dll");

MessageBoxA(NULL, "This is the message body", "message_caption", 0);

26.

In the following example, lr_log_message sends a message to the log file if the connection to the server fails.

char* abort="aborting...";

...

if (init() < 0) {

       lr_log_message ("login failed: %s", abort);}

       return(0);

}

In the next example, an Iteration Number type parameter called "iteration" was defined in VuGen. The lr_log_message function sends a message to the LoadRunner Controller or Application Management Admin Center indicating the current iteration number.

lr_log_message ( "We are on iteration #%s", lr_eval_string ( "{iteration}" ) );

27.

In the following example, lr_message sends a message if the connection to the server fails.

char* abort="aborting...";

...

if (init() < 0) {

       lr_message ("login failed: %s", abort);}

return(0);

}

28.

In this example, an Iteration Number type parameter called "iteration" was defined in VuGen. The lr_output_message function sends a message to the Load Runner Controller or the Application Mangement Admin Center indicating the current iteration number.

lr_output_message ( "We are on iteration #%s", lr_eval_string ( "{iteration}" ) );

29.

In the following example, lr_save_datetime is used to retrieve tomorrow's date.

lr_save_datetime("Tomorrow is %B %d %Y", DATE_NOW + ONE_DAY, "next");

lr_output_message(lr_eval_string("{next}"));

30.

In the following example, lr_save_int assigns the string representation of the value of variable num times 2 to parameter param1.

int num;

num = 5;

lr_save_int(num * 2, "param1");

The value of param1 is now "10".

31.

In this example, the lr_set_debug_message function enables the full trace option just before a call to lrd_fetch, which the user needs to debug because it has been giving unexpected results.

The second invocation of lr_set_debug_message resets the debug level to what it was formerly, by turning off (LR_SWITCH_OFF) the Extended message level.

32.

In the following segment, lr_start_timer and lr_end_timer are used to calculate the time spent on checks. This is then subtracted from the time spent on transaction "sampleTrans" with lr_wasted_time.

double time_elapsed, duration, waste;

merc_timer_handle_t timer;

       lr_start_transaction("sampleTrans");

       web_url("index.htm",

              "URL=http://localhost/index.htm",

              "TargetFrame=",

              "Resource=0",

              "RecContentType=text/html",

              "Referer=",

              "Snapshot=t1.inf",

              "Mode=HTML",

              LAST);

       timer = lr_start_timer();

/* Do some checks the duration of which

is not to be included in the transaction. */

       web_image_check("ImgCheck1",

              "src=index_files/image002.jpg",

              LAST);

       web_image_check("ImgCheck2",

              "src=index_files/planets.gif",

              LAST);

// How long did the tests take in seconds.

       time_elapsed = lr_end_timer(timer);

// Convert to millisecond.s

       waste = time_elapsed * 1000;

/* Remove the time the checks took from

       the transaction. */

       lr_wasted_time(waste);

        lr_end_transaction("sampleTrans", LR_AUTO);

---

In the following segment, lr_think_time instructs the script to pause for 10 seconds after accessing a link and submitting a form.

In the following example, a user data point is defined that checks the CPU every second and records the result.

for (i=0;i<100;i++) {

       measure_cpu ( );
       cpu_val=cpu_check();

       lr_user_data_point("cpu", cpu_val);

       sleep(1);

}

30

The following segment demonstrates the use of timers to collect wasted time, and the use of lr_wasted_time to remove that wasted time from the transactions. The output log segments below show that the effects are not reported in the Vuser log, but are reported in the Analysis session.

31.

In the following example, lr_whoami retrieves information about a Vuser and places it into a message string. The message string contains Vuser login information that is used to connect with a server.

Note that memory for vuser_group is allocated automatically. Do not alter the string.

           

        vuser_group, id, scid);

In these examples, web_save_param_length creates three new parameters, Param7_Length, Param10_Length,and Param16_Length, and stores the length of each respective source parameter as a hexidecimal number.

       // Create a parameter 7 characters long

       lr_save_string("ABCDEFG", "Param7");

       web_save_param_length("Param7", "Base=Hexadecimal", LAST);

The following examples are presented for web_reg_save_param.

• Example 1: Saving simple text strings
• Case of saving a single string
• Case requiring handling arrays
• Example 2: Saving a text by using binary boundaries
• Example 3: Saving a text specified with an offset and length
• Example 4: Boundaries containing special characters

Example 1: Saving simple text strings

In this example, web_reg_save_param is used to save a value from the response to a web_submit_form call. The value saved is used in a subsequent web_submit_form call.

In the Mercury Tours sample program, the server response to the web_submit_form call below contains the following radio button options:

<tr bgcolor=#66cccc><th>Flight<th>Departure time<th>Cost

<tr bgcolor=#66CCff><td align=center><input type = radio name=outboundFlight value=230;378;11/20/2003 checked >Blue Sky Air 230<td align=center>8am<td align=center>$ 378

<tr bgcolor=#eeeeee><td align=center><input type = radio name=outboundFlight value=231;337;11/20/2003>Blue Sky Air 231<td align=center>1pm<td align=center>$ 337

and so on.

To submit a reservation, the outboundFlight value is required. web_reg_save_param is used to save the outboundFlightvalue.

• Case of saving a single string
• Case requiring handling arrays

Case of saving a single string

To reserve the default flight, save the "checked" value, and pass it to web_submit_form. The html segment for the default value is:

name=outboundFlight value=230;378;11/20/2003 checked >

/*This web_reg_save_param call applies to the following action function: web_submit_form. */

       web_reg_save_param("outFlightVal",

       "LB=outboundFlight value=", "RB= checked >", LAST);

       web_submit_form("reservations.pl",

              "Snapshot=t4.inf",

              ITEMDATA,

              "Name=depart", "Value=London", ENDITEM,

              "Name=departDate", "Value=11/20/2003", ENDITEM,

              "Name=findFlights.y", "Value=16", ENDITEM,

              LAST);

/*

The result of the web_reg_save_param having been called before the web_submit_form is:

*/

// Now use the saved outFlightVal

       web_submit_form("reservations.pl_2",

              "Snapshot=t5.inf",

              ITEMDATA,

              "Name=outboundFlight", "Value={outFlightVal}", ENDITEM,

              "Name=reserveFlights.x", "Value=92", ENDITEM,

              "Name=reserveFlights.y", "Value=10", ENDITEM,

              LAST);

/*

Action.c(34): Notify: Parameter Substitution: parameter "outFlightVal" = "230;378;11/20/2003" */

 

Case requiring handling arrays

If you want to test the last option returned by the web_submit_form call, save all the matches and then handle the array.

This example shows the use of web_reg_save_param with "ORD=ALL" to get an array of parameters. The last item in the array is then used to correlate a web_submit_form call.

char outFlightParam[50]; // The name of the parameter for correlation

char outFlightParamVal[50]; // The formatted value of outFlightParam

/*

This web_reg_save_param call applies to the following action function, web_submit_form. Because of the "ORD=ALL" argument, it saves all the values that have the given left and right boundaries to an array of parameters.

The SaveLen argument is used to restrict the length to 18 characters because the default value is "230;378;11/20/2003 checked >". We restrict the length so as not to capture the " checked ".

*/

       web_reg_save_param("outFlightVal",

              "LB=outboundFlight value=", "RB=>",

              "ORD=ALL",

              "SaveLen=18",

              LAST);

       web_submit_form("reservations.pl",

              "Snapshot=t4.inf",

The next problem is to get the highest array element, identified with the parameter outFlightVal_count. This parameter is automatically created by the script recorder. You do not have to enter anything in the script.

/* Get the name of the parameter, in this case "outFlightVal_4".

Put it in brackets so it can be an input to an lr_eval_string call.

Note that the brackets in the second argument to sprintf are not indicating a script parameter to sprintf. They are string literals that will be part of outFlightParam after the call.

In the second call to sprintf, those brackets indicate a parameter to lr_eval_string.

       sprintf(outFlightParam, "{outFlightVal_%s}",

              lr_eval_string("{outFlightVal_count}"));

/* outFlightParam is now "{outFlightVal_4}" */

       /* Now get the "Value" argument for web_submit_form, in the

              format "Value=xxxx")

       /* Now the string outFlightParamVal can be passed

              to web_submit_form */

       web_submit_form("reservations.pl_2",

              "Snapshot=t5.inf",

              ITEMDATA,

              "Name=outboundFlight",outFlightParamVal, ENDITEM,

              "Name=reserveFlights.x", "Value=92", ENDITEM,

              "Name=reserveFlights.y", "Value=10", ENDITEM,

              LAST);

 

 

Example 2: Saving a text by using binary boundaries

The following example uses BIN type boundaries. The left boundary is composed of 3F and DD. The right boundary is composed of CCand b.

web_reg_save_param("p", "LB/BIN=\\x3F\\xDD", "RB/BIN=\\xCCb", LAST);

 

Example 3: Saving a text specified with an offset and length

The following example specifies an offset and length. The boundaries for the HTML string "Astra on TESTSERVER", are "Astra " (note the space which follows the word) and "TestServer". This should return "on" but since the offset is 1 (i.e. start at the second character) and the length of data to save is 1, then the string saved to TestParam is "n".

web_reg_save_param("Param1", "LB=Astra ", "RB= TESTSERVER",

       "SaveOffset=1", "SaveLen=1", LAST);

 

Example 4: Boundaries containing special characters

The following example shows the use of escaping in the C language when the boundaries contain special characters.

The following HTML segment contains new line characters (paragraph markers) after each "<strong>" and quote marks around each class name. We want to save "Georgiana Darcy" to parameter "UserName". The segment containing the new line and quotes has to be included in the left boundary because "Name:", which precedes the segment, is required for the occurrence to be unique. The ORD attribute cannot be used in this case because the length of the list preceding the relevant element varies.

<span class="surveyQuestionReview"><strong> UserID:</strong></span><strong>

    </strong> <span class="surveyAnswerReview">Revere18041775</span> <br>

<span class="surveyQuestionReview"><strong> Name:</strong></span><strong>

    </strong> <span class="surveyAnswerReview">Georgiana Darcy</span> <br>

<span class="surveyQuestionReview"><strong> Company:</strong></span><strong>

    </strong> <span class="surveyAnswerReview">Pride and Prejudice</span> <br>

The function is:

web_reg_save_param("UserName",

"LB=Name:</strong></span><strong> \n    </strong> <span class=\"surveyAnswerReview\">",

              "RB=</span> <br>",

              LAST);

Note the \n for the new line character, and that the quote characters need to be escaped: \".

In the following example, web_reg_find searches for the text string "Welcome". If the string is not found, it fails and the script execution stops.

       // Run the Web Tours sample

       web_url("MercuryWebTours",

              "URL=http://localhost/MercuryWebTours/",

              "Resource=0",

              "RecContentType=text/html",

              "Referer=",

              "Snapshot=t1.inf",

              "Mode=HTML",

              LAST);

// Set up check for successful login by looking for "Welcome"

       web_reg_find("Text=Welcome",

              LAST);

// Now log in

       web_submit_form("login.pl",

              "Snapshot=t2.inf",

              ITEMDATA,

              "Name=username", "Value=jojo", ENDITEM,

              "Name=password", "Value=bean", ENDITEM,

              "Name=login.x", "Value=35", ENDITEM,

              "Name=login.y", "Value=14", ENDITEM,

              LAST);

-------

In the following example, the web_find function searches for the name "John" in the employees.html page.

web_url("index.html",
        "URL=http://server1/people/employees.html",
        "TargetFrame=",
        LAST);

web_find("Employee Check",
        "expect=notfound",
        "matchcase=yes",
        "onfailure=abort",
        "report=failure",
        "repeat=no",
        "what=John",
        LAST);

Example 2

In the following example, the web_find function searches for the text "Home" which is between "Go to" and "Page".

web_url("index.html",
        "URL=http://server1/",
        "TargetFrame=",
       LAST);

web_find("Text Check",
        "RightOf=Go to",
        "LeftOf=page",
        "What=Home",
       LAST);
