#stack as you normally would

create public net and subnet:

neutron net-create ext-net --router:external True --provider:physical_network external --provider:network_type flat
neutron subnet-create ext-net 10.35.6.0/23 --name ext-subnet --gateway 10.35.7.254 --allocation-pool start=10.35.6.120,end=10.35.6.130

edit  /opt/stack/tempest/etc/tempest.conf by adding the net_id of the net created just above.

example:
public_network_id = 90245de5-a3ef-4d77-b360-c3e0ad4d94cc

cd /opt/stack/tempest
ostestr --pdb tempest.scenario.test_network_basic_ops.TestNetworkBasicOps.test_network_basic_ops

it takes a few mins, but eventually you will see test completion.
