Sets the message level for the script execution.


function lr.set_debug_message(  message_level, on_off  )


Function lr.set_debug_message(  message_level, on_off  )
Example: Debug Message LevelsMessage Functions


message_levelOne of the Message Log Runtime Settings.
on_offA switch to activate or deactivate a specific message level setting. Use one of the On-Off Constants.

The lr.set_debug_message function sets the debug message level, message_lvl, for the script execution. By setting a message level, you determine which information is sent. The setting is enabled by passing LR_SWITCH_ON as on_off, and disabled with LR_SWITCH_OFF.

The messages are sent to the log or Vuser output.

Message levels are generally set in the script's Runtime Settings dialog box. The value can be changed from the current runtime settings value. For example, if the script's current message level in the runtime settings is set at "Brief" mode, the value can be increased to "Extended log" (LR_MSG_CLASS_EXTENDED_LOG):

     lr.set_debug_message(LR_MSG_CLASS_EXTENDED_LOG, LR_SWITCH_ON)

and later decreased to "Brief" once again:


To enable logging that is disabled in the runtime settings, set the message level to another level. For example:

     lr.set_debug_message (lr.MSG_CLASS_EXTENDED_LOG, lr.SWITCH_ON)

After enabling the logging, return to the disabled state by setting the debug level to zero (0) and activating the option using the lr.SWITCH_ON switch as the second parameter.

The message levels Result Data, Parameter Substitution, and Full Trace, are specific details, or sub-settings, of the Extended log setting. To set one of these sub-settings you can use logical Or's in your message_level argument.

Using LR_SWITCH_DEFAULT as on_off sets the on/off status of message_level to the default value regardless of previous calls to lr.set_debug_message. Use LR_SWITCH_DEFAULT with a single message_level argument. It does not work with ORed message_level settings.
