# PURPOSE:
# This script clones the openstack-ansible-tests repository to the
# tests/common folder in order to be able to re-use test components
# for role testing. This is intended to be the thinnest possible
# shim for test execution outside of OpenStack CI.

# WARNING:
# This file is maintained in the openstack-ansible-tests repository.
# https://opendev.org/openstack/openstack-ansible-tests/src/run_tests.sh
# If you need to modify this file, update the one in the openstack-ansible-tests
# repository and then update this file as well. The purpose of this file is to
# prepare the host and then execute all the tox tests.
