# Status: this is a work in progress, under test.
#
# How to use:
#   $ git clone https://gerrit.opnfv.org/gerrit/models
#   $ cd models/tests
#   $ bash vHello_Tacker.sh [tacker-cli|tacker-api] [setup|start|run|stop|clean]
#   tacker-cli: use Tacker CLI
#   tacker-api: use Tacker RESTful API (not yet implemented)
#   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
