LoadRunner Common functions

1. Intweb_reg_save_param ("parameter name", "Lb= left Boundary", "rb= right Boundary", last);/registration function, which is used before the parameter value appears, the return value is 0 when the registration succeeds, and the return value of 1 when the registration fails. The left and right boundaries need to be determined according to the Severresponse code of the relevant steps in the TreeView. Use the above function to get the first number that meets the criteria.

2. Web_reg_save_param ("parameter name", "Lb= left Boundary", "rb= right Boundary", "Ord=all", last);/when the argument has multiple values, add "Ord=all" to get all the values. After successful registration, {parameter name _count} represents the number of values obtained, {parameter name _1} is the first value, {parameter name _2} is the second number.

3. Lr_save_string ("String variable", "parameter name")/pass the value in the character variable to the specified parameter. This function is used to change the numeric value of the datafile type parameter.

4. Lr_eval_string ("{parameter name}")/get the numeric value of the parameter. You can obtain a numeric value for a registered or datafile type parameter. Eval is the abbreviation for evaluation (valuation, evaluation, assignment).

5. int sprintf (char * string, const Char*format_string[,args]);/String Assignment function

Action () { int index=56; charfilename[64],*suffix= "TXT"; sprintf (filename, "log_%d.%s", Index,suffix); Lr_output_message ("thenewfilenameis%s", filename); return 0; } Output:Thenewfilenameislog_56.txt

6. Char*strcat (Char*to,constchar*from);/append a string to the back of another string

7. Web_find ("Find_time", "what=2006-03-0118:21:16.882", last);/Add checkpoints to check whether the string "2006-03-0118:21:16.882" appears on the current page. Find_time the name of the checkpoint for which you entered any.

lr_stop_transaction/Stop the collection of transaction data

lr_stop_transaction_instance/Stop a transaction (specified by its handle) data collection

lr_wasted_time/eliminates the time wasted on all open transactions

lr_end_sub_transaction/the end of the token child transaction for profiling

r_end_transaction/Mark LoadRunner End of transaction

lr_end_transaction_instance/marks the end of a transaction instance for profiling

lr_get_attrib_long/retrieves a long type variable used in a script command line

lr_get_attrib_string/retrieves the string used in the script command line
