Functional tests
================
There is a suite of functional tests under the
python-manilaclient/tests/functional directory. Unlike unit tests, these
tests perform API calls to Manila and are designed to run on a DevStack.
Adding functional tests to your changes is not mandatory but it's certainly
a good practice and it's encouraged.
Prerequisite
------------
You need to have manila running somewhere. If you wish to use DevStack to
run manila, a good place to start would be the `manila contributor guide`_.
.. note::
We absolutely recommend using a ``fake shared file system back end`` as
opposed to a real storage system, because our tests are written with the
assumption that all APIs manila exposes are usable. In reality,
different real world storage back ends have `different capabilities`_ and
this project doesn't need to worry about them to provide a general purpose
interface to Manila. A fake driver provides fake storage, so don't
expect to be able to mount or use the shared file systems that you
create with it.
You can use the following local.conf file to configure DevStack including
Manila using a few fake back ends:
.. code-block:: console
[[local|localrc]]

ADMIN_PASSWORD=nomoresecret
DATABASE_PASSWORD=$ADMIN_PASSWORD
RABBIT_PASSWORD=$ADMIN_PASSWORD
SERVICE_PASSWORD=$ADMIN_PASSWORD

Configuration
-------------
The functional tests require a couple of configuration files, so you will need
to generate them before running the tests.
For DevStack
^^^^^^^^^^^^
On your DevStack machine, you can run the following script. It assumes that
``devstack`` is cloned onto your base folder.
.. code-block:: console
DEST=${DEST:-/opt/stack}
MANILACLIENT_DIR=${MANILACLIENT_DIR:-$DEST/python-manilaclient}
MANILACLIENT_CONF="$MANILACLIENT_DIR/etc/manilaclient/manilaclient.conf"
# Go to the manilaclient dir
cd $MANILACLIENT_DIR
# Give permissions
sudo chown -R $USER:stack .
# Create manilaclient config file
touch $MANILACLIENT_CONF
# Import functions from devstack
source $HOME/devstack/functions
# Set options to config client.
source $HOME/devstack/openrc demo demo
export OS_TENANT_NAME=${OS_PROJECT_NAME:-$OS_TENANT_NAME}
iniset $MANILACLIENT_CONF DEFAULT username $OS_USERNAME
iniset $MANILACLIENT_CONF DEFAULT tenant_name $OS_TENANT_NAME
iniset $MANILACLIENT_CONF DEFAULT password $OS_PASSWORD
iniset $MANILACLIENT_CONF DEFAULT auth_url $OS_AUTH_URL
iniset $MANILACLIENT_CONF DEFAULT project_domain_name $OS_PROJECT_DOMAIN_NAME
iniset $MANILACLIENT_CONF DEFAULT user_domain_name $OS_USER_DOMAIN_NAME
iniset $MANILACLIENT_CONF DEFAULT project_domain_id $OS_PROJECT_DOMAIN_ID
iniset $MANILACLIENT_CONF DEFAULT user_domain_id $OS_USER_DOMAIN_ID
source $HOME/devstack/openrc admin demo
export OS_TENANT_NAME=${OS_PROJECT_NAME:-$OS_TENANT_NAME}
iniset $MANILACLIENT_CONF DEFAULT admin_username $OS_USERNAME
iniset $MANILACLIENT_CONF DEFAULT admin_tenant_name $OS_TENANT_NAME
iniset $MANILACLIENT_CONF DEFAULT admin_password $OS_PASSWORD
iniset $MANILACLIENT_CONF DEFAULT admin_auth_url $OS_AUTH_URL
iniset $MANILACLIENT_CONF DEFAULT admin_project_domain_name $OS_PROJECT_DOMAIN_NAME
iniset $MANILACLIENT_CONF DEFAULT admin_user_domain_name $OS_USER_DOMAIN_NAME
iniset $MANILACLIENT_CONF DEFAULT admin_project_domain_id $OS_PROJECT_DOMAIN_ID
iniset $MANILACLIENT_CONF DEFAULT admin_user_domain_id $OS_USER_DOMAIN_ID
# Suppress errors in cleanup of resources
SUPPRESS_ERRORS=${SUPPRESS_ERRORS_IN_CLEANUP:-False}
iniset $MANILACLIENT_CONF DEFAULT suppress_errors_in_cleanup $SUPPRESS_ERRORS
# Set access type usage specific to dummy driver that we are using in CI
iniset $MANILACLIENT_CONF DEFAULT access_types_mapping "nfs:ip,cifs:user"
# Dummy driver is capable of running share migration tests
iniset $MANILACLIENT_CONF DEFAULT run_migration_tests "True"
# Running mountable snapshot tests in dummy driver
iniset $MANILACLIENT_CONF DEFAULT run_mount_snapshot_tests "True"
# Create share network and use it for functional tests if required
USE_SHARE_NETWORK=$(trueorfalse True USE_SHARE_NETWORK)
.. code-block:: console
if [[ ${USE_SHARE_NETWORK} = True ]]; then
SHARE_NETWORK_NAME=${SHARE_NETWORK_NAME:-ci}
DEFAULT_NEUTRON_NET=$(openstack network show private -c id -f value)
DEFAULT_NEUTRON_SUBNET=$(openstack subnet show private-subnet -c id -f value)
NEUTRON_NET=${NEUTRON_NET:-$DEFAULT_NEUTRON_NET}
NEUTRON_SUBNET=${NEUTRON_SUBNET:-$DEFAULT_NEUTRON_SUBNET}
manila share-network-create --name $SHARE_NETWORK_NAME --neutron-net $NEUTRON_NET --neutron-subnet $NEUTRON_SUBNET
iniset $MANILACLIENT_CONF DEFAULT share_network $SHARE_NETWORK_NAME
iniset $MANILACLIENT_CONF DEFAULT admin_share_network $SHARE_NETWORK_NAME
fi
.. code-block:: console
# Set share type if required
if [[ "$SHARE_TYPE" ]]; then
iniset $MANILACLIENT_CONF DEFAULT share_type $SHARE_TYPE
fi
Running the tests
-----------------
To run all functional tests make sure you are in the top level of your
python-manilaclient module (e.g. /opt/stack/python-manilaclient/) and simply
run::
tox -e functional
This will create a virtual environment, load all the packages from
test-requirements.txt and run all functional tests.
