Sending Messages to Output
When you run a scenario, the Controller's Output window displays valuable
information about script execution. You can include statements in each script to
send error and notification messages to the Controller--which the Controller will
display in the Output window. For example, you could insert a message that
displays the current state of the client application. You can also save these
messages to a file.
Note
: Do not to send messages from within a transaction. Doing so lengthens the
transaction execution time and may skew the actual transaction results.
You can use the following message functions in your Vuser scripts:
lr_error_message
Sends an error message to the output window.
lr_output_message
Sends a special notification to the output window.
lr_log_message
Sends an output message directly to a file,
output.txt
, located in the Vuser script directory.
This function is useful in preventing output
messages from interfering with TCP/IP traffic.
lr_vuser_status_message
Generates and prints formatted output to the
Controller Vuser status area.
