(1) upload files on LoadRunner

"Action= https://testserver/console/importStudent.do",

"Method=POST"

"EncType=multipart/form-data"

"RecContentType=text/html"

Note: script recording can be done using either Http/Html protocol or Click and Script protocol. The above scripts are recorded using Http/Html. It should be noted that no matter which protocol is used for recording, the file path and file name to be uploaded can only be English characters, not Chinese characters. Otherwise, the binary stream uploaded to the file may be recorded into the script in LR at the same time.

This problem also shows that LR's support for Chinese is far from enough.

The following is a more detailed example of the application.

Action ()

{

/ / defines the variable trans_time of type double, which is used to hold the execution time of the transaction.

Double trans_time

/ / defines the variable status of type int, which is used to hold the returned value of the transaction execution.

Int status

Lr_start_transaction ("Test")

/ / use the built-in function lr_get_transaction_duration to get the execution time of the transaction.

Trans_time=lr_get_transaction_duration ("Test")

The following is an example of the application of the web_submit_data function in LR's help documentation, as can be seen from this example.

/ / so far, a LoadRunner has obtained a complete file name
