+NFVbench Xtesting test cases and Xtesting CI integration
+--------------------------------------------------------
+
+NFVbench can leverages on `Xtesting CI <https://galaxy.ansible.com/collivier/xtesting>`_ and the common test case execution proposed by `Xtesting <https://xtesting.readthedocs.io/en/latest/>`_.
+Thanks to a simple test case list, this tool deploys anywhere plug-and-play `CI/CD toolchains in a few commands <https://wiki.opnfv.org/pages/viewpage.action?pageId=32015004>`_.
+In addition, it supports multiple components such as Jenkins and Gitlab CI (test schedulers) and multiple deployment models such as all-in-one or centralized services.
+
+NFVbench using Xtesting and Xtesting CI will permit:
+
+- smoothly assemble multiple heterogeneous test cases
+- generate the Jenkins jobs
+- deploy local CI/CD toolchains everywhere
+- dump all test case results and logs for third-party conformance review
+
+Xtesting CI only requires GNU/Linux as Operating System and asks for a few dependencies as described in Deploy your own Xtesting CI/CD toolchains:
+
+- python-virtualenv
+- docker.io
+- git
+
+Please note the next two points depending on the GNU/Linux distributions and the network settings:
+
+- SELinux: you may have to add --system-site-packages when creating the virtualenv ("Aborting, target uses selinux but python bindings (libselinux-python) aren't installed!")
+- Proxy: you may set your proxy in env for Ansible and in systemd for Docker https://docs.docker.com/config/daemon/systemd/#httphttps-proxy
+
+Here is the default NFVbench tree as proposed in ``xtesting/ansible/host_vars/127.0.0.1`` file:
+
+- ``/home/opnfv/nfvbench``
+
+File content:
+
+.. code-block:: bash
+
+ docker_args:
+ env: {}
+ volumes:
+ - /lib/modules/$(uname -r):/lib/modules/$(uname -r)
+ - /usr/src/kernels:/usr/src/kernels -v /dev:/dev
+ - /home/opnfv/nfvbench:/tmp/nfvbench
+
+Please note: replace ``/home/opnfv/nfvbench`` with appropriate path to permit NFVbench container to access config file
+
+To deploy your own CI toolchain running NFVbench:
+
+.. code-block:: bash
+
+ virtualenv nfvbench
+ . nfvbench/bin/activate
+ pip install ansible
+ ansible-galaxy install collivier.xtesting
+ git clone https://gerrit.opnfv.org/gerrit/nfvbench nfvbench
+ ansible-playbook nfvbench/xtesting/ansible/site.yml
+
+
+NFVbench Xtesting test cases and existing CI chain
+--------------------------------------------------
+
+For test automation purpose, Xtesting framework can be used as an executor of NFVbench test cases and called by a CI chain (Jenkins, Gitlab CI ...).
+Xtesting use a testcases.yaml file to list and run test case. One basic testcases.yaml is provided by NFVbench natively but can be override.
+
+Example of CI scenario:
+
+.. image:: images/nfvbench-xtesting.png
+
+1. Run NFVbench container using Xtesting python library
+
+The NFVbench container can be started using docker run command.
+
+To run NFVbench using docker run:
+
+.. code-block:: bash
+
+ docker run --rm \
+ -e S3_ENDPOINT_URL=http://127.0.0.1:9000 \
+ -e S3_DST_URL=s3://xtesting/$BUILD_TAG/$JOB_NAME-$BUILD_ID \
+ -e HTTP_DST_URL=http://127.0.0.1:8181/$BUILD_TAG/$JOB_NAME-$BUILD_ID \
+ -e AWS_ACCESS_KEY_ID=xtesting \
+ -e AWS_SECRET_ACCESS_KEY=xtesting \
+ -e TEST_DB_URL=http://127.0.0.1:8000/api/v1/results \
+ -e NODE_NAME=nfvbench \
+ -e BUILD_TAG=$BUILD_TAG \
+ --privileged \
+ -v /lib/modules/$(uname -r):/lib/modules/$(uname -r) \
+ -v /usr/src/kernels:/usr/src/kernels -v /dev:/dev \
+ -v $HOME/nfvbench:/tmp/nfvbench \
+ -v $HOME/workspace/$JOB_NAME/results:/var/lib/xtesting/results \
+ opnfv/nfvbench run_tests -t 10kpps-pvp-run -r -p

+
+2. Run Xtesting test cases
+
+Executed directly by NFVbench docker entrypoint after docker start.
+
+3. Perform NFVbench test
+
+Xtesting call NFVbench python script to execute test case scenario and wait for run to be terminated.
+
+4. Export NFVbench result
+
+If ``-r`` option is used, results are pushed to a DB through Xtesting.
+If ``-p`` option is used, results are pushed to a S3 service through Xtesting.
+
+
+Override testcases.yaml file
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+To replace existing testcases.yaml file, using Xtesting CI add the volume mapping in ``xtesting/ansible/host_vars/127.0.0.1`` file:
+
+.. code-block:: bash
+
+ docker_args:
+ env: {}
+ volumes:
+ - /lib/modules/$(uname -r):/lib/modules/$(uname -r)
+ - /usr/src/kernels:/usr/src/kernels -v /dev:/dev
+ - /home/opnfv/nfvbench:/tmp/nfvbench
+ - /home/opnfv/nfvbench/xtesting/testcases.yaml:/usr/local/lib/python3.6/dist-packages/xtesting/ci/testcases.yaml
+
+* ``/home/opnfv/nfvbench/xtesting/testcases.yaml:/usr/local/lib/python3.6/dist-packages/xtesting/ci/testcases.yaml`` : volume mapping to pass testcases.yaml file between the host and the docker space. Host path required testcases.yaml file inside.
+
+
+To replace existing testcases.yaml file, using NFVbench container:
+
+.. code-block:: bash
+
+ docker run --name nfvbench --detach --privileged -v /lib/modules/$(uname -r):/lib/modules/$(uname -r) -v /usr/src/kernels:/usr/src/kernels -v /dev:/dev -v $HOME/nfvbench:/tmp/nfvbench \
+ -v $HOME/nfvbench/xtesting/testcases.yaml:/usr/local/lib/python3.6/dist-packages/xtesting/ci/testcases.yaml \
+ opnfv/nfvbench
+
+
+* ``$HOME/nfvbench/xtesting/testcases.yaml:/usr/local/lib/python3.6/dist-packages/xtesting/ci/testcases.yaml`` : volume mapping to pass testcases.yaml file between the host and the docker space. Host path required testcases.yaml file inside.

+Examples of manual run
+~~~~~~~~~~~~~~~~~~~~~~
+
+If NFVbench container is already started in CLI mode (see Starting NFVbench in CLI mode dedicated chapter).
+To do a single run at 10,000pps bi-directional (or 5kpps in each direction) using the PVP packet path:
+
+.. code-block:: bash
+
+ docker exec -it nfvbench run_tests -t 10kpps-pvp-run
+
+Xtesting option used:
+
+* ``-t 10kpps-pvp-run`` : specify the test case to run
+
+To pass all test cases:
+
+.. code-block:: bash
+
+ docker exec -it nfvbench run_tests -t all
+
+Xtesting option used:
+
+* ``-t all`` : select all test cases existing in testcases.yaml file
+
