Introduction
============

This document describes how to install and configure Functest in OPNFV.

High level architecture
-----------------------

The high level architecture of Functest within OPNFV can be described as follows::

 CIMC/Lights+out management                 Admin     Private   Public   Storage

All the libraries and dependencies needed by all the Functest tools are
pre-installed in the Docker image.
This allows running Functest on any platform on any Operating System.

The automated mechanisms inside the Functest Docker container will:

  * retrieve OpenStack credentials
  * prepare the environment according to the SUT
  * perform the appropriate tests
  * push the results into the OPNFV test result database


This Docker image can be integrated into CI or deployed independently.

Please note that the Functest container has been designed for OPNFV, however, it
would be possible to adapt it to any VIM+controller environment since most of the
test cases are integrated from upstream communities.

The test cases are described in the Functest User Guide `[2]`_


Prerequisites
=============

The OPNFV deployment is out of the scope of this document but it can be found in
`[4]`_. The OPNFV platform is considered as the System Under Test (SUT) in this
document.

Several prerequisites are needed for Functest:

    #. A Jumphost to run Functest on
    #. Docker daemon shall be installed on the Jumphost
    #. A public/external network created on the SUT
    #. Connectivity from the Jumphost to the SUT public/external network
    #. Connectivity from the Jumphost to the SUT management network

NOTE: “Jumphost” refers to any server which meets the previous requirements.
Normally it is the same server from where the OPNFV deployment has been
triggered previously.

Docker installation
-------------------

.. _Ubuntu: https://docs.docker.com/installation/ubuntulinux/
.. _RHEL: https://docs.docker.com/installation/rhel/

Log on your Jumphost and install docker (e.g. for Ubuntu)::

 curl -sSL https://get.docker.com/ | sh

Add your user to docker group to be able to run commands without sudo::

 sudo usermod -aG docker <your_user>


References:

  * Ubuntu_
  * RHEL_

External network on SUT
-----------------------

Some of the tests against the VIM (Virtual Infrastructure Manager) need an
existing public network to succeed. This is needed, for example, to create
floating IPs to access instances from the public network (i.e. Docker container).

By default, the four OPNFV installers provide a fresh installation with
an external network created along with a router. Make sure that subnet
is reachable from the Jumphost


Connectivity to OPNFV management network
----------------------------------------

Some of the Functest tools need to have access to the OpenStack management
network of the controllers `[1]`_.

For this reason, an interface shall be configured in the Jumphost in the
OpenStack management network range.

For example, if the management network is on VLAN 300 and subnet 192.168.1.0/24
and assuming that eth1 is the physical interface with access to that subnet::

    ip link add name eth1.300 link eth1 type vlan id 300
    ip link set eth1.300 up
    ip addr add 192.168.1.66/24 dev eth1.300

This is just an example about how to configure an interface with vlan, but it might
differ depending on the deployment settings on each installer. Check the
corresponding installer instructions for more info.


Installation and configuration
==============================

.. include:: ./configguide.rst


Integration in CI
=================

In CI we use the Docker image and execute the appropriate commands within the
container from Jenkins.

Docker creation in set-functest-env builder `[3]`_::

    envs="INSTALLER_TYPE=${INSTALLER_TYPE} -e INSTALLER_IP=${INSTALLER_IP} -e NODE_NAME=${NODE_NAME}"
    [...]
    docker pull opnfv/functest:latest_stable
    cmd="docker run -id -e $envs ${labconfig} ${sshkey} ${res_volume} opnfv/functest:latest_stable /bin/bash"
    echo "Functest: Running docker run command: ${cmd}"
    ${cmd}
    docker ps -a
    sleep 5
    container_id=$(docker ps | grep 'opnfv/functest:latest_stable' | awk '{print $1}' | head -1)
    echo "Container ID=${container_id}"
    if [ -z ${container_id} ]; then
        echo "Cannot find opnfv/functest container ID ${container_id}. Please check if it is existing."
        docker ps -a
        exit 1
    fi
    echo "Starting the container: docker start ${container_id}"
    docker start ${container_id}
    sleep 5
    docker ps
    if [ $(docker ps | grep 'opnfv/functest:latest_stable' | wc -l) == 0 ]; then
        echo "The container opnfv/functest with ID=${container_id} has not been properly started. Exiting..."
        exit 1
    fi
    cmd="${FUNCTEST_REPO_DIR}/docker/prepare_env.sh"
    echo "Executing command inside the docker: ${cmd}"
    docker exec ${container_id} ${cmd}


Test execution in functest-all builder `[3]`_::

  echo "Functest: run $FUNCTEST_SUITE_NAME"
  cmd="${FUNCTEST_REPO_DIR}/docker/run_tests.sh --test $FUNCTEST_SUITE_NAME ${flag}"
  container_id=$(docker ps -a | grep opnfv/functest | awk '{print $1}' | head -1)
  docker exec $container_id $cmd

Docker clean in functest-cleanup builder `[3]`_::

    echo "Cleaning up docker containers/images..."
    # Remove previous running containers if exist
    if [[ ! -z $(docker ps -a | grep opnfv/functest) ]]; then
    echo "Removing existing opnfv/functest containers..."
    docker ps | grep opnfv/functest | awk '{print $1}' | xargs docker stop
    docker ps -a | grep opnfv/functest | awk '{print $1}' | xargs docker rm
    fi

    # Remove existing images if exist
    if [[ ! -z $(docker images | grep opnfv/functest) ]]; then
    echo "Docker images to remove:"
    docker images | head -1 && docker images | grep opnfv/functest
    image_tags=($(docker images | grep opnfv/functest | awk '{print $2}'))
    for tag in "${image_tags[@]}"; do
        echo "Removing docker image opnfv/functest:$tag..."
        docker rmi opnfv/functest:$tag
    done
    fi
