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 Developer Quick-Start to deploy Magnum in a devstack environment.
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=$(iniget /etc/magnum/magnum.conf api host)
sed -i "s/127.0.0.1/$HOST/" functional_creds.conf
# update admin password
. /opt/stack/devstack/openrc admin admin
iniset functional_creds.conf admin pass $OS_PASSWORD
# update demo password
. /opt/stack/devstack/openrc demo demo
iniset functional_creds.conf auth password $OS_PASSWORD
Set the DNS name server to be used by your cluster nodes (e.g. 8.8.8.8):
# update DNS name server
. /opt/stack/devstack/openrc demo demo
iniset functional_creds.conf magnum dns_nameserver <dns-svr-ip-address>
Create the necessary keypair and flavor:
. /opt/stack/devstack/openrc admin admin
openstack keypair create --public-key ~/.ssh/id_rsa.pub default
openstack flavor create --id 100 --ram 1024 --disk 10 --vcpus 1 m1.magnum
openstack flavor create --id 200 --ram 512 --disk 10 --vcpus 1 s1.magnum
. /opt/stack/devstack/openrc demo demo
openstack keypair create --public-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
https://docs.openstack.org/tempest/latest/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
To avoid creating multiple clusters simultaneously, you can execute the tests with concurrency 1:
tox -e functional-k8s -- --concurrency 1
