lr_debug_message基本用法

intlr_debug_message (unsignedintmessage_level, const char *format, ...);

Thelr_debug_messagefunction sends a debug message when the specified message level is active. If the specified message level is not active, a message is not issued. You can set the active message level to MSG_CLASS_BRIEF_LOG or MSG_CLASS_EXTENDED_LOG from the user interface or by using lr_set_debug_message. To determine the current level, use lr_get_debug_message.

Note that you can also specify multiple message levels with an OR separator ("|"). If any one of the levels are active (from the UI), the message is issued to the Output window. If none of the levels are active, the message is not issued.

The message is sent to the output window. To display the debug messages in the LoadRunner output window or Application Management agent log file, use the Expert Mode Settings. Activate Expert Mode (Tools>Expert Mode) and then chooseTools>Options>Debug Informationand select theGeneralcheck box.

例子：

In the following example,lr_debug_messageissues a message to the log when either the Parameters Substitution or Result Data classes are set.

lr_set_debug_message(LR_MSG_CLASS_EXTENDED_LOG, LR_SWITCH_ON);

if (rc>2000)

lr_debug_message(LR_MSG_CLASS_RESULT_DATA |         LR_MSG_CLASS_PARAMETERS, "Operation failed.");
