# What this is: 3-Node Hello World blueprint deployment test for the OPNFV Models
# project, using Tacker as VNFM.
#
# Status: this is a work in progress, under test.
#
# How to use:
#   $ git clone https://gerrit.opnfv.org/gerrit/ves
#   $ cd ves/tests
#   $ bash vHello_3Node_Tacker.sh [setup|start|run|stop|clean]
#        [monitor|traffic|pause|nic]
#   setup: setup test environment
#   start: install blueprint and run test
#   run: setup test environment and run test
#   stop: stop test and uninstall blueprint
#   clean: cleanup after test
