+=========================================
+Conducting ONAP VNF Testing with Dovetail
+=========================================
+
+Overview
+--------
+
+As the LFN verification framework, Dovetail covers ONAP VNF tests by integrating
+VNF SDK and VVP. 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
