This guide introduces only how to use Dovetail to run the tests. +For more details about VNF SDK and VVP, please refer to `ONAP VNF SDK Compliance Verification Program +<https://docs.onap.org/en/latest/submodules/vnfsdk/model.git/docs/files/VNFSDK-LFN-CVC.html>`_ +and `ONAP VVP <https://docs.onap.org/en/latest/submodules/vvp/documentation.git/docs/index.html>`_. + + +Definitions and abbreviations +----------------------------- + +- LFN - Linux Foundation Networking +- ONAP - Open Network Automation Platform +- VNF - Virtual Network Function +- SDK - Software Development Kit +- VVP - VNF Validation Program + + +Environment Preparation +----------------------- + +Currently, there are only VNF package validation tests which do not rely on the +ONAP deployment. As a result, the preparation is very simple. + + +Install Docker +^^^^^^^^^^^^^^ + +The main prerequisite software for Dovetail is Docker. Please refer to `official +Docker installation guide <https://docs.docker.com/install/>`_ which is relevant +to your Test Host's operating system. + + +Install VNF SDK Backend (optional) +^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ + +If it is TOSCA based VNF, then VNF SDK Backend must be installed before the +tests. There is a `docker-compose.yml` in VNFSDK repo which runs 2 docker containers. Use +the following commands to run the containers: + +.. code-block:: bash + + $ export NEXUS_DOCKER_REPO=nexus3.onap.org:10001 + $ export REFREPO_TAG=1.2.1-STAGING-20181228T020411Z + $ export POSTGRES_TAG=latest + $ export MTU=1450 + $ wget https://raw.githubusercontent.com/onap/vnfsdk-refrepo/master/vnfmarket-be/deployment/install/docker-compose.yml + $ sudo docker-compose up -d + + +The command `docker ps` can be used to check if the 2 containers named +'refrepo' and 'postgres' are running. + +The VNF package to be tested should be copied to the container 'refrepo'. + +.. code-block:: bash + + $ sudo docker cp /path/to/VNF/name.csar refrepo:/opt + + +Run Tests with Dovetail +^^^^^^^^^^^^^^^^^^^^^^^ + +For convenience and as a convention, we will create a home directory for storing +all Dovetail related config files and results files: + +.. code-block:: bash + + $ mkdir -p ${HOME}/dovetail + $ export DOVETAIL_HOME=${HOME}/dovetail + + +For example, here we set Dovetail home directory to be ``${HOME}/dovetail``. +Afterwards, we will create a directory named ``pre_config`` inside this directory +to store all Dovetail config related files: + +.. code-block:: bash + + $ mkdir -p ${DOVETAIL_HOME}/pre_config + + +There should be a file `env_config.sh` inside this directory to provide some info. +For TOSCA based VNFs, it should look like this: + +.. code-block:: bash + + $ cat ${DOVETAIL_HOME}/pre_config/env_config.sh + export HOST_URL="http://<docker host ip>:8702" + export CSAR_FILE="/path/to/VNF/copied/in/container/name.csar" + + +For HEAT based VNFs, it should create `vnf_dir` under `pre_config` and copy all +HEAT template VNF packages to `vnf_dir`. + +.. code-block:: bash + + $ mkdir -p ${DOVETAIL_HOME}/pre_config/vnf_dir + + +Configuration file `env_config.sh` should look like this for HEAT based VNFs: + +.. code-block:: bash + + $ cat ${DOVETAIL_HOME}/pre_config/env_config.sh + export VNF_DIRECTORY="/path/to/pre_config/vnf_dir" + + +Use the command below to create a Dovetail container and get access to its shell: + +.. code-block:: bash + + $ sudo docker run --privileged=true -it \ + -e DOVETAIL_HOME=$DOVETAIL_HOME \ + -v $DOVETAIL_HOME:$DOVETAIL_HOME \ + -v /var/run/docker.sock:/var/run/docker.sock \ + opnfv/dovetail:<tag> /bin/bash + + +The ``-e`` option sets the DOVETAIL_HOME environment variable in the container +and the ``-v`` options mount files from the Test Host to the destination path +inside the container. The latter option allows the Dovetail container to read +the configuration files and write result files into DOVETAIL_HOME on the Test +Host. The user should be within the Dovetail container shell, once the command +above is executed. In order to run ONAP VNF tests 'latest' <tag> must be used. + +Run VNF tests with the following command: + +.. code-block:: bash + + $ dovetail run --testsuite <suite name> -d + + +For TOSCA based VNFs, `<suite name>` is `onap.tosca.2019.04` and for +HEAT based ones, it is `onap.heat.2019.04`. + + +NOTE: If Dovetail run fails when testing `onap-vtp.validate.csar`, then follow the +below guidelines to run the test again. + +.. code-block:: bash + + $ sudo docker exec -it refrepo bash + $ export OPEN_CLI_HOME=/opt/vtp + $ cd $OPEN_CLI_HOME/bin + $ ./oclip-grpc-server.sh + $ #Exit docker by running CTRL+p+q |
