Category: Performance Testing

Some scripts cannot be run between certain times, this is especially the case when we are running long duration tests or preparing test data by data-seeding overnight.

In these cases it may be useful to specify times when you don’t want a script to run, for example you might want to schedule a script so that it can’t run when backups or system restarts are taking place.

The attached script contains an example of a function (CheckExclusionTime) which can prevent a script from running between certain times. The script is made more complicated by the fact that you might want to prevent a script from running between 23:50 one day and 00:15 the next day. To achieve the desired result it is necessary to convert any time into an integer value representing the number of minutes which have passed from 00:00 on Monday until the current time and then calculating if the current time falls within the excluded period.

The integers 1 through to 7 represent the days Monday through to Sunday.

Other integers are used to represent the exclusion start time and exclusion end time.

Another Mark Sibley function.

This converts a number into text. It relies on the number already being saved as a character string.

It’s currently set to create a title case word but could be amended to create an all upper or lower case word easily enough.

The words it creates are going to be mostly nonsense, however because it could have occasionally created a real word I removed all of the vowels to reduce the likelihood of creating any offensive words.

Copy and paste the following into a LoadRunner script to see it in action.

int ConvertNumberToText(char * sInput)
{
int i;
int c;
char n;
char sText[50];
char sCharacter[10];
char * sUpper[10];
char * sLower[10];

sUpper[0] = “B”; sUpper[1] = “C”; sUpper[2] = “D”; sUpper[3] = “F”; sUpper[4] = “G”;
sUpper[5] = “H”; sUpper[6] = “J”; sUpper[7] = “K”; sUpper[8] = “L”; sUpper[9] = “M”;

sLower[0] = “b”; sLower[1] = “c”; sLower[2] = “d”; sLower[3] = “f”; sLower[4] = “g”;
sLower[5] = “h”; sLower[6] = “j”; sLower[7] = “k”; sLower[8] = “l”; sLower[9] = “m”;

for (i = 0; i < strlen(sInput); i++) {

sscanf(sInput+i,”%c”,&n);
sprintf(sCharacter,”%c”,n);
c = atoi(sCharacter);

// This ensures that the first character is an upper case letter and that the rest are lower case.
// If you want a word that is either all upper or lower case then amend the appropriate [sUpper] or [sLower]
if (i == 0) {strcpy(sText,sUpper[c]);}
else  {strcat(sText,sLower[c]);}
}

lr_save_string(sText,”sName”);
lr_output_message(lr_eval_string(“Output:[{sName}]”));
}

Action()
{
int p = 459332;
char string[50];

itoa(p,string,10);

lr_save_string(“50328″,”sNumber”);

ConvertNumberToText(string);
ConvertNumberToText(“2168”);
ConvertNumberToText(lr_eval_string(“{sNumber}”));

return 0;
