Running functional tests

This is a guide for developers who want to run functional tests in their local machine.

Prerequisite

You need to have a Magnum instance running somewhere. If you are using devstack, follow the developer quickstart guide to deploy Magnum in a devstack environment

http://docs.openstack.org/developer/magnum/dev/quickstart.html

Configuration

The functional tests require a couple configuration files, so you'll need to generate them yourself.

For devstack

If you're using devstack, you can copy and modify the devstack configuration:

cd /opt/stack/magnum
cp /opt/stack/tempest/etc/tempest.conf /opt/stack/magnum/etc/tempest.conf
cp functional_creds.conf.sample functional_creds.conf

# update the IP address
HOST=$(cat /etc/magnum/magnum.conf | awk '/^host = /{print $3}')
sed -i "s/127.0.0.1/$HOST/" functional_creds.conf

# update admin password
source /opt/stack/devstack/openrc admin admin
iniset functional_creds.conf admin pass $OS_PASSWORD

# update demo password
source /opt/stack/devstack/openrc demo demo
iniset functional_creds.conf auth password $OS_PASSWORD

Set the DNS name server to be used in your bay nodes (e.g. 8.8.8.8):

# update DNS name server
source /opt/stack/devstack/openrc demo demo
iniset functional_creds.conf magnum dns_nameserver <dns-svr-ip-address>

Create the necessary keypair and flavor:

source /opt/stack/devstack/openrc admin admin
nova keypair-add --pub-key ~/.ssh/id_rsa.pub default
nova flavor-create  m1.magnum 100 1024 8 1
nova flavor-create  s1.magnum 200 512 8 1

source /opt/stack/devstack/openrc demo demo
nova keypair-add --pub-key ~/.ssh/id_rsa.pub default

You may need to explicitly upgrade required packages if you've installed them before and their versions become too old:

UPPER_CONSTRAINTS=/opt/stack/requirements/upper-constraints.txt
sudo pip install -c $UPPER_CONSTRAINTS -U -r test-requirements.txt

Outside of devstack

If you are not using devstack, you'll need to create the configuration files. The /etc/tempest.conf configuration file is documented here

http://docs.openstack.org/developer/tempest/configuration.html#tempest-configuration

Here's a reasonable sample of tempest.conf settings you might need:

[auth]
use_dynamic_credentials=False
test_accounts_file=/tmp/etc/magnum/accounts.yaml
admin_username=admin
admin_password=password
admin_project_name=admin

[identity]
disable_ssl_certificate_validation=True
uri=https://identity.example.com/v2.0
auth_version=v2
region=EAST

[identity-feature-enabled]
api_v2 = true
api_v3 = false
trust = false

[oslo_concurrency]
lock_path = /tmp/

[magnum]
image_id=22222222-2222-2222-2222-222222222222
nic_id=11111111-1111-1111-1111-111111111111
keypair_id=default
flavor_id=small
magnum_url=https://magnum.example.com/v1

[debug]
trace_requests=true

A sample functional_creds.conf can be found in the root of this project named functional_creds.conf.sample

When you run tox, be sure to specify the location of your tempest.conf using TEMPEST_CONFIG_DIR:

export TEMPEST_CONFIG_DIR=/tmp/etc/magnum/
tox -e functional-api

Execution

Magnum has different functional tests for each COE and for the API. All the environments are detailed in Magnum's tox.ini:

cat tox.ini | grep functional- | awk -F: '{print $2}' | sed s/]//

To run a particular subset of tests, specify that group as a tox environment. For example, here is how you would run all of the kubernetes tests:

tox -e functional-k8s

To run a specific test or group of tests, specify the test path as a positional argument:

tox -e functional-k8s -- magnum.tests.functional.k8s.v1.test_k8s_python_client.TestBayModelResource
