## Automatic test module for SIPp.
|
|
|
|
|
##
|
|
|
|
|
## This module will need a test driver for each SIPp scenario:
|
|
|
|
|
## - For simple scenario, i.e: make/receive call (including auth), this
|
|
|
|
|
## test module can auto-generate a default test driver, i.e: make call
|
|
|
|
|
## or apply auto answer. Just name the SIPp scenario using "uas" or
|
|
|
|
|
## "uac" prefix accordingly.
|
|
|
|
|
## - Custom test driver can be defined in a python script file containing
|
|
|
|
|
## a list of the PJSUA instances and another list for PJSUA expects/
|
|
|
|
|
## commands. The custom test driver file must use the same filename as
|
|
|
|
|
## the SIPp XML scenario. See samples of SIPp scenario + its driver
|
|
|
|
|
## in tests/pjsua/scripts-sipp/ folder for detail.
|
|
|
|
|
##
|
|
|
|
|
## Here are defined macros that can be used in the custom driver:
|
|
|
|
|
## - $SIPP_PORT : SIPp binding port
|
|
|
|
|
## - $SIPP_URI : SIPp SIP URI
|
|
|
|
|
## - $PJSUA_PORT[N] : binding port of PJSUA instance #N
|
|
|
|
|
## - $PJSUA_URI[N] : SIP URI of PJSUA instance #N
