+Introduction
+============
+
+The goal of this document is to describe the OPNFV Functest test cases and to
+provide a procedure to execute them. In the OPNFV Danube system release,
+a Functest CLI utility is introduced for easier execution of test procedures.
+
+**IMPORTANT**: It is assumed here that the Functest Docker container is already
+properly deployed and that all instructions described in this guide are to be
+performed from *inside* the deployed Functest Docker container.
+
+.. include:: ./introduction.rst
+
+The different test cases are described in the remaining sections of this document.
+
+VIM (Virtualized Infrastructure Manager)
+----------------------------------------
+
+Healthcheck
+^^^^^^^^^^^
+In Colorado release a new Tier 'healthcheck' with one testcase 'healthcheck'
+was introduced. The healthcheck testcase verifies that some basic IP connectivity
+and essential operations of OpenStack functionality over the command line are
+working correctly.
+
+In particular, the following verifications are performed:
+
+ * DHCP agent functionality for IP address allocation
+ * Openstack Authentication management functionality via the Keystone API
+ * OpenStack Image management functionality via the Glance API
+ * OpenStack Block Storage management functionality via the Cinder API
+ * OpenStack Networking management functionality via the Neutron API
+ * Openstack Compute management functionality via the NOVA API
+
+Self-obviously, successful completion of the 'healthcheck' testcase is a
+necessary pre-requisite for the execution of all other test Tiers.
+
+
+vPing_ssh
+^^^^^^^^^
+
+Given the script **ping.sh**::
+
+ #!/bin/sh
+ while true; do
+ ping -c 1 $1 2>&1 >/dev/null
+ RES=$?
+ if [ "Z$RES" = "Z0" ] ; then
+ echo 'vPing OK'
+ break
+ else
+ echo 'vPing KO'
+ fi
+ sleep 1
+ done
+
+
+The goal of this test is to establish an SSH connection using a floating IP
+on the Public/External network and verify that 2 instances can talk over a Private
+Tenant network::
+
+ vPing_ssh test case
+ +-------------+ +-------------+
+ | | | |
+ | | Boot VM1 with IP1 | |
+ | +------------------->| |
+ | Tester | | System |
+ | | Boot VM2 | Under |
+ | +------------------->| Test |
+ | | | |
+ | | Create floating IP | |
+ | +------------------->| |
+ | | | |
+ | | Assign floating IP | |
+ | | to VM2 | |
+ | +------------------->| |
+ | | | |
+ | | Establish SSH | |
+ | | connection to VM2 | |
+ | | through floating IP| |
+ | +------------------->| |
+ | | | |
+ | | SCP ping.sh to VM2 | |
+ | +------------------->| |
+ | | | |
+ | | VM2 executes | |
+ | | ping.sh to VM1 | |
+ | +------------------->| |
+ | | | |
+ | | If ping: | |
+ | | exit OK | |
+ | | else (timeout): | |
+ | | exit Failed | |
+ | | | |
+ +-------------+ +-------------+
+
+This test can be considered as an "Hello World" example.
+It is the first basic use case which **must** work on any deployment.
+
+vPing_userdata
+^^^^^^^^^^^^^^
+
+This test case is similar to vPing_ssh but without the use of Floating IPs
+and the Public/External network to transfer the ping script.
+Instead, it uses Nova metadata service to pass it to the instance at booting time.
+As vPing_ssh, it checks that 2 instances can talk to
+each other on a Private Tenant network::
+
+ vPing_userdata test case
+ +-------------+ +-------------+
+ | | | |
+ | | Boot VM1 with IP1 | |
+ | +------------------->| |
+ | | | |
+ | | Boot VM2 with | |
+ | | ping.sh as userdata| |
+ | | with IP1 as $1. | |
+ | +------------------->| |
+ | Tester | | System |
+ | | VM2 exeutes ping.sh| Under |
+ | | (ping IP1) | Test |
+ | +------------------->| |
+ | | | |
+ | | Monitor nova | |
+ | | console-log VM 2 | |
+ | | If ping: | |
+ | | exit OK | |
+ | | else (timeout) | |
+ | | exit Failed | |
+ | | | |
+ +-------------+ +-------------+
+
+When the second VM boots it will execute the script passed as userdata
+automatically. The ping will be detected by periodically capturing the output
+in the console-log of the second VM.
+
+
+Tempest
+^^^^^^^
+
+Tempest `[2]`_ is the reference OpenStack Integration test suite.
+It is a set of integration tests to be run against a live OpenStack cluster.
+Tempest has suites of tests for:
+
+ * OpenStack API validation
+ * Scenarios
+ * Other specific tests useful in validating an OpenStack deployment
+
+Functest uses Rally `[3]`_ to run the Tempest suite.
+Rally generates automatically the Tempest configuration file **tempest.conf**.
+Before running the actual test cases,
+Functest creates the needed resources (user, tenant) and
+updates the appropriate parameters into the configuration file.
+
+When the Tempest suite is executed, each test duration is measured and the full
+console output is stored to a *log* file for further analysis.
+
+The Tempest testcases are distributed accross two
+Tiers:
+
+ * Smoke Tier - Test Case 'tempest_smoke_serial'
+ * Components Tier - Test case 'tempest_full_parallel'
+
+NOTE: Test case 'tempest_smoke_serial' executes a defined set of tempest smoke
+tests with a single thread (i.e. serial mode). Test case 'tempest_full_parallel'
+executes all defined Tempest tests using several concurrent threads
+(i.e. parallel mode). The number of threads activated corresponds to the number
+of available logical CPUs.
+
+The goal of the Tempest test suite is to check the basic functionalities of the
+different OpenStack components on an OPNFV fresh installation, using the
+corresponding REST API interfaces.
+
+
+Rally bench test suites
+^^^^^^^^^^^^^^^^^^^^^^^
+
+Rally `[3]`_ is a benchmarking tool that answers the question:
+
+*How does OpenStack work at scale?*
+
+The goal of this test suite is to benchmark all the different OpenStack modules and
+get significant figures that could help to define Telco Cloud KPIs.
+
+The OPNFV Rally scenarios are based on the collection of the actual Rally scenarios:
+
+ * authenticate
+ * cinder
+ * glance
+ * heat
+ * keystone
+ * neutron
+ * nova
+ * quotas
+ * requests
+
+A basic SLA (stop test on errors) has been implemented.
+
+The Rally testcases are distributed accross two Tiers:
+
+ * Smoke Tier - Test Case 'rally_sanity'
+ * Components Tier - Test case 'rally_full'
+
+NOTE: Test case 'rally_sanity' executes a limited number of Rally smoke test
+cases. Test case 'rally_full' executes the full defined set of Rally tests.
+
+SNAPS
+-----
+
+SNAPS stands for "SNA/NFV Application development Platform and Stack".
+This project seeks to develop baseline OpenStack NFV installations. It has been
+developed by Steven Pisarski and provided an object oriented library to perform
+functional and performance tests. It has been declined in several test suites in
+Functest, 2 are part of healthcheck tier, one belongs to smoke tier.
+
+connection check
+^^^^^^^^^^^^^^^^
+Connection_check consists in 9 test cases (test duration < 5s) checking the
+connectivity with Glance, Keystone, Neutron, Nova and the external network.
+
+api_check
+^^^^^^^^^
+This test case verifies the retrieval of OpenStack clients: Keystone, Glance,
+Neutron and Nova and may perform some simple queries. When the config value of
+snaps.use_keystone is True, functest must have access to the cloud's private
+network.
+This suite consists in 49 tests (test duration< 2 minutes)
+
+snaps_smoke
+^^^^^^^^^^^
+This test case contains tests that setup and destroy environments with VMs with
+and without Floating IPs with a newly created user and project. Set the config
+value snaps.use_floating_ips (True|False) to toggle this functionality. When
+the config value of snaps.use_keystone is True, functest must have access
+the cloud's private network.
+This suite consists in 38 tests (test duration < 10 minutes)
+
+More information on SNAPS can be found in  `[13]`_
+
+
+SDN Controllers
+---------------
+
+There are currently 2 available controllers:
+
+ * OpenDaylight (ODL)
+ * ONOS
+
+OpenDaylight
+^^^^^^^^^^^^
+
+The OpenDaylight (ODL) test suite consists of a set of basic tests inherited
+from the ODL project using the Robot `[11]`_ framework.
+The suite verifies creation and deletion of networks, subnets and ports with
+OpenDaylight and Neutron.
+
+The list of tests can be described as follows:
+
+ * Basic Restconf test cases
+ * Connect to Restconf URL
+ * Check the HTTP code status
+
+ * Neutron Reachability test cases
+ * Get the complete list of neutron resources (networks, subnets, ports)
+
+ * Neutron Network test cases
+ * Check OpenStack networks
+ * Check OpenDaylight networks
+ * Create a new network via OpenStack and check the HTTP status code returned by Neutron
+ * Check that the network has also been successfully created in OpenDaylight
+
+ * Neutron Subnet test cases
+ * Check OpenStack subnets
+ * Check OpenDaylight subnets
+ * Create a new subnet via OpenStack and check the HTTP status code returned by Neutron
+ * Check that the subnet has also been successfully created in OpenDaylight
+
+ * Neutron Port test cases
+ * Check OpenStack Neutron for known ports
+ * Check OpenDaylight ports
+ * Create a new port via OpenStack and check the HTTP status code returned by Neutron
+ * Check that the new port has also been successfully created in OpenDaylight
+
+ * Delete operations
+ * Delete the port previously created via OpenStack
+ * Check that the port has been also succesfully deleted in OpenDaylight
+ * Delete previously subnet created via OpenStack
+ * Check that the subnet has also been successfully deleted in OpenDaylight
+ * Delete the network created via OpenStack
+ * Check that the network has also been succesfully deleted in OpenDaylight
+
+Note: the checks in OpenDaylight are based on the returned HTTP status
+code returned by OpenDaylight.
+
+
+ONOS
+^^^^
+
+TestON Framework is used to test the ONOS SDN controller functions.
+The test cases deal with L2 and L3 functions.
+The ONOS test suite can be run on any ONOS compliant scenario.
+
+The test cases are described as follows:
+
+ * onosfunctest: The main executable file contains the initialization of
+ the docker environment and functions called by FUNCvirNetNB and
+ FUNCvirNetNBL3
+
+ * FUNCvirNetNB
+
+ * Create Network: Post Network data and check it in ONOS

+
+security_scan
+^^^^^^^^^^^^^
+
+Security Scanning, is a project to insure security compliance and vulnerability
+checks, as part of an automated CI / CD platform delivery process.
+
+The project makes use of the existing SCAP format `[6]`_ to perform deep
+scanning of NFVI nodes, to insure they are hardened and free of known CVE
+reported vulnerabilities.
+
+The SCAP content itself, is then consumed and run using an upstream opensource tool
+known as OpenSCAP `[7]`_.
+
+The OPNFV Security Group have developed the code that will called by the OPNFV Jenkins
+build platform, to perform a complete scan. Resulting reports are then copied to the
+OPNFV functest dashboard.
+
+The current work flow is as follows:
+
+ * Jenkins Build Initiated
+ * security_scan.py script is called, and a config file is passed to the script as
+ an argument.
+ * The IP addresses of each NFVi node (compute / control) are gathered
+ * A scan profile is matched to the node type.
+ * The OpenSCAP application is remotely installed onto each target node gathered
+ on step 3, using upstream packaging (rpm and .deb).
+ * A scan is made against each node gathered within step 3.
+ * HTML Reports are downloaded for rendering on a dashboard.
+ * If the config file value 'clean' is set to 'True' then the application installed in
+ step 5 is removed, and all reports created at step 6 are deleted.
+
+Security scan is supported by Apex, TODO....
+
+
+
+VNF
+---
+
+
+vIMS
+^^^^
+The IP Multimedia Subsystem or IP Multimedia Core Network Subsystem (IMS) is an
+architectural framework for delivering IP multimedia services.
+
+vIMS has been integrated in Functest to demonstrate the capability to deploy a
+relatively complex NFV scenario on the OPNFV platform. The deployment of a complete
+functional VNF allows the test of most of the essential functions needed for a
+NFV platform.
+
+The goal of this test suite consists of:
+
+ * deploy a VNF orchestrator (Cloudify)
+ * deploy a Clearwater vIMS (IP Multimedia Subsystem) VNF from this
+ orchestrator based on a TOSCA blueprint defined in `[5]`_
+ * run suite of signaling tests on top of this VNF
+
+The Clearwater architecture is described as follows:

+Overview of the Functest suites
+===============================
+
+Functest is the OPNFV project primarily targeting function testing.
+In the Continuous Integration pipeline, it is launched after an OPNFV fresh
+installation to validate and verify the basic functions of the
+infrastructure.
+
+The current list of test suites can be distributed over 5 main domains: VIM
+(Virtualised Infrastructure Manager), Controllers (i.e. SDN Controllers),
+Features, VNF (Virtual Network Functions) and MANO stacks.
+
+Functest test suites are also distributed in the OPNFV testing categories:
+healthcheck, smoke, features, components, performance, VNF, Stress tests.
+
+All the Healthcheck and smoke tests of a given scenario must be succesful to
+validate the scenario for the release.
+

+
+As shown in the above table, Functest is structured into different 'domains',
+'tiers' and 'test cases'. Each 'test case' usually represents an actual
+'Test Suite' comprised -in turn- of several test cases internally.
+
+Test cases also have an implicit execution order. For example, if the early
+'healthcheck' Tier testcase fails, or if there are any failures in the 'smoke'
+Tier testcases, there is little point to launch a full testcase execution round.
+
+In Danube, we merged smoke and sdn controller tiers in smoke tier.
+
+An overview of the Functest Structural Concept is depicted graphically below:
+
+.. figure:: ../images/concepts_mapping_final.png
+ :align: center
+ :alt: Functest Concepts Structure
+
+Some of the test cases are developed by Functest team members, whereas others
+are integrated from upstream communities or other OPNFV projects. For example,
+`Tempest <http://docs.openstack.org/developer/tempest/overview.html>`_ is the
+OpenStack integration test suite and Functest is in charge of the selection,
+integration and automation of those tests that fit suitably to OPNFV.
+
+The Tempest test suite is the default OpenStack smoke test suite but no new test
+cases have been created in OPNFV Functest.
+
+The results produced by the tests run from CI are pushed and collected into a
+NoSQL database. The goal is to populate the database with results from different
+sources and scenarios and to show them on a `Functest Dashboard`_. A screenshot
+of a live Functest Dashboard is shown below:
+
+** TODO **
+.. figure:: ../images/FunctestDashboardDanube.png
+ :align: center
+ :alt: Functest Dashboard
+
+
+Basic components (VIM, SDN controllers) are tested through their own suites.
+Feature projects also provide their own test suites with different ways of
+running their tests.
+
+The notion of domain has been introduced in the description of the test cases
+stored in the Database.
+This parameters as well as possible tags can be used for the Test case catalog.
+
+vIMS test case was integrated to demonstrate the capability to deploy a
+relatively complex NFV scenario on top of the OPNFV infrastructure.
+
+Functest considers OPNFV as a black box. As of Danube release the OPNFV
+offers a lot of potential combinations:
+
+ * 3 controllers (OpenDaylight, ONOS, OpenContrail)
+ * 4 installers (Apex, Compass, Fuel, Joid)
+
+Most of the tests are runnable by any combination, but some tests might have
+restrictions imposed by the utilized installers or due to the available
+deployed features. The system uses the environment variables (INSTALLER_IP and
+DEPLOY_SCENARIO) to automatically determine the valid test cases, for each given
+environment.
+
+A convenience Functest CLI utility is also available to simplify setting up the
+Functest evironment, management of the OpenStack environment (e.g. resource
+clean-up) and for executing tests.
+The Functest CLI organised the testcase into logical Tiers, which contain in
+turn one or more testcases. The CLI allows execution of a single specified
+testcase, all test cases in a specified Tier, or the special case of execution
+of **ALL** testcases. The Functest CLI is introduced in more detail in the
+section `Executing the functest suites`_ of this document.

+Executing the functest suites
+=============================
+
+Manual testing
+--------------
+
+This section assumes the following:
+ * The Functest Docker container is running
+ * The docker prompt is shown
+ * The Functest environment is ready (Functest CLI command 'functest env prepare'
+ has been executed)
+
+If any of the above steps are missing please refer to the Functest Config Guide
+as they are a prerequisite and all the commands explained in this section **must** be
+performed **inside the container**.
+
+The Functest CLI offers two commands (functest tier ...) and (functest testcase ... )
+for the execution of Test Tiers or Test Cases::
+
+ root@22e436918db0:~/repos/functest/ci# functest tier --help
+ Usage: functest tier [OPTIONS] COMMAND [ARGS]...
+
+ Options:
+ -h, --help Show this message and exit.
+
+ Commands:
+ get-tests Prints the tests in a tier.
+ list Lists the available tiers.
+ run Executes all the tests within a tier.
+ show Shows information about a tier.
+ root@22e436918db0:~/repos/functest/ci# functest testcase --help
+
+ Usage: functest testcase [OPTIONS] COMMAND [ARGS]...
+
+ Options:
+ -h, --help Show this message and exit.
+
+ Commands:
+ list Lists the available testcases.
+ run Executes a test case.
+ show Shows information about a test case.

+ :
+ :
+ etc.
+
+To list the test cases which are part of a specific Test Tier, the 'get-tests'
+command is used with 'functest tier'::
+
+ root@22e436918db0:~/repos/functest/ci# functest tier get-tests healthcheck
+ Test cases in tier 'healthcheck':
+ ['healthcheck']
+
+
+Please note that for some scenarios some test cases might not be launched.
+For example, the last example displayed only the 'odl' testcase for the given
+environment. In this particular system the deployment does not support the 'onos' SDN
+Controller Test Case; for example.
+
+**Important** If you use the command 'functest tier run <tier_name>', then the
+Functest CLI utility will call **all valid Test Cases**, which belong to the
+specified Test Tier, as relevant to scenarios deployed to the SUT environment.
+Thus, the Functest CLI utility calculates automatically which tests can be
+executed and which cannot, given the environment variable **DEPLOY_SCENARIO**,
+which is passed in to the Functest docker container.
+
+Currently, the Functest CLI command 'functest testcase run <testcase_name>', supports
+two possibilities::
+
+ * Run a single Test Case, specified by a valid choice of <testcase_name>
+ * Run ALL test Test Cases (for all Tiers) by specifying <testcase_name> = 'all'
+
+Functest includes a cleaning mechanism in order to remove all the OpenStack
+resources except those present before running any test. The script
+*$REPOS_DIR/functest/functest/utils/generate_defaults.py* is called once when setting up
+the Functest environment (i.e. CLI command 'functest env prepare') to snapshot
+all the OpenStack resources (images, networks, volumes, security groups, tenants,
+users) so that an eventual cleanup does not remove any of these defaults.
+
+The script **clean_openstack.py** which is located in
+*$REPOS_DIR/functest/functest/utils/* is normally called after a test execution. It is
+in charge of cleaning the OpenStack resources that are not specified in the
+defaults file generated previously which is stored in
+*/home/opnfv/functest/conf/os_defaults.yaml* in the Functest docker container.
+
+It is important to mention that if there are new OpenStack resources created
+manually after preparing the Functest environment, they will be removed, unless
+you use the special method of invoking the test case with specific suppression
+of clean up. (See the `Troubleshooting`_ section).
+
+The reason to include this cleanup meachanism in Functest is because some
+test suites such as Tempest or Rally create a lot of resources (users,
+tenants, networks, volumes etc.) that are not always properly cleaned, so this
+function has been set to keep the system as clean as it was before a
+full Functest execution.
+
+Although the Functest CLI provides an easy way to run any test, it is possible to
+do a direct call to the desired test script. For example:
+
+ python $REPOS_DIR/functest/functest/opnfv_tests/OpenStack/vPing/vPing_ssh.py -d
+
+
+Automated testing
+-----------------
+
+As mentioned previously, the Functest Docker container preparation as well as
+invocation of Test Cases can be called within the container from the Jenkins CI
+system. There are 3 jobs that automate the whole process. The first job runs all
+the tests referenced in the daily loop (i.e. that must been run daily), the second
+job runs the tests referenced in the weekly loop (usually long duration tests run
+once a week maximum) and the third job allows testing test suite by test suite specifying
+the test suite name. The user may also use either of these Jenkins jobs to execute
+the desired test suites.
+
+One of the most challenging task in the Danube release consists
+in dealing with lots of scenarios and installers. Thus, when the tests are
+automatically started from CI, a basic algorithm has been created in order to
+detect whether a given test is runnable or not on the given scenario.
+Some Functest test suites cannot be systematically run (e.g. ODL suite can not
+be run on an ONOS scenario). The daily/weekly notion has been introduces in
+Colorado in order to save CI time and avoid running systematically
+long duration tests. It was not used in Colorado due to CI resource shortage.
+The mechanism remains however as part of the CI evolution.
+
+CI provides some useful information passed to the container as environment
+variables:
+
+ * Installer (apex|compass|daisy|fuel|joid), stored in INSTALLER_TYPE
+ * Installer IP of the engine or VM running the actual deployment, stored in INSTALLER_IP
+ * The scenario [controller]-[feature]-[mode], stored in DEPLOY_SCENARIO with
+
+ * controller = (odl|onos|ocl|nosdn)
+ * feature = (ovs(dpdk)|kvm|sfc|bgpvpn|multisites)
+ * mode = (ha|noha)
+
+The constraints per test case are defined in the Functest configuration file
+*/home/opnfv/repos/functest/functest/ci/testcases.yaml*::
+
+ tiers:
+ -
+ name: healthcheck
+ order: 0
+ ci_loop: '(daily)|(weekly)'
+ description : >-
+ First tier to be executed to verify the basic
+ operations in the VIM.
+ testcases:
+ -
+ name: healthcheck
+ criteria: 'status == "PASS"'
+ blocking: true
+ description: >-
+ This test case verifies the basic OpenStack services like
+ Keystone, Glance, Cinder, Neutron and Nova.
+
+ dependencies:
+ installer: ''
+ scenario: ''
+
+ -
+ name: smoke
+ order: 1
+ ci_loop: '(daily)|(weekly)'
+ description : >-
+ Set of basic Functional tests to validate the OpenStack deployment.
+ testcases:
+ -
+ name: vping_ssh
+ criteria: 'status == "PASS"'
+ blocking: true
+ description: >-
+ This test case verifies: 1) SSH to an instance using floating
+ IPs over the public network. 2) Connectivity between 2 instances
+ over a private network.
+ dependencies:
+ installer: ''
+ scenario: '^((?!bgpvpn|odl_l3).)*$'
+ run:
+ module: 'functest.opnfv_tests.openstack.vping.vping_ssh'
+ class: 'VPingSSH'
+ ....
+
+We may distinguish 2 levels in the test case description:
+ * Tier level
+ * Test case level
+
+At the tier level, we define the following parameters:
+
+ * ci_loop: indicate if in automated mode, the test case must be run in daily and/or weekly jobs
+ * description: a high level view of the test case
+
+For a given test case we defined:
+ * the name of the test case
+ * the criteria (experimental): a criteria used to declare the test case as PASS or FAIL
+ * blocking: if set to true, if the test is failed, the execution of the following tests is canceled
+ * the description of the test case
+ * the dependencies: a combination of 2 regex on the scenario and the installer name
+ * run: In Danube we introduced the notion of abstract class in order to harmonize the way to run internal, feature or vnf tests
+
+For further details on abstraction classes, see developper guide.
+
+Additional parameters have been added in the desription in the Database.
+The target is to use the configuration stored in the Database and consider the
+local file as backup if the Database is not reachable.
+The additional fields related to a test case are:
+ * trust: we introduced this notion to put in place a mechanism of scenario promotion.
+ * Version: it indicates since which version you can run this test
+ * domains: the main domain covered by the test suite
+ * tags: a list of tags related to the test suite
+
+The order of execution is the one defined in the file if all test cases are selected.
+
+In CI daily job the tests are executed in the following order:
+
+ 1) healthcheck (blocking)
+ 2) smoke: both vPings are blocking
+ 3) Feature project tests cases
+
+In CI weekly job we add 2 tiers:
+
+ 4) VNFs (vIMS)
+ 5) Components (Rally and Tempest long duration suites)
+
+As explained before, at the end of an automated execution, the OpenStack resources
+might be eventually removed.
+Please note that a system snapshot is taken before any test case execution.
+
+This testcase.yaml file is used for CI, for the CLI and for the automatic reporting.

+Troubleshooting
+===============
+
+This section gives some guidelines about how to troubleshoot the test cases
+owned by Functest.
+
+**IMPORTANT**: As in the previous section, the steps defined below must be
+executed inside the Functest Docker container and after sourcing the OpenStack
+credentials::
+
+ . $creds
+
+or::
+
+ source /home/opnfv/functest/conf/openstack.creds
+
+VIM
+---
+
+This section covers the test cases related to the VIM (healthcheck, vping_ssh,
+vping_userdata, tempest_smoke_serial, tempest_full_parallel, rally_sanity,
+rally_full).
+
+vPing common
+^^^^^^^^^^^^
+For both vPing test cases (**vPing_ssh**, and **vPing_userdata**), the first steps are
+similar:
+
+ * Create Glance image
+ * Create Network
+ * Create Security Group
+ * Create Instances
+
+After these actions, the test cases differ and will be explained in their
+respective section.
+
+These test cases can be run inside the container, using new Functest CLI as follows::
+
+ $ functest testcase run vping_ssh
+ $ functest testcase run vping_userdata
+
+The Functest CLI is designed to route a call to the corresponding internal
+python scripts, located in paths:
+*$REPOS_DIR/functest/functest/opnfv_tests/vPing/CI/libraries/vPing_ssh.py* and
+*$REPOS_DIR/functest/functest/opnfv_tests/vPing/CI/libraries/vPing_userdata.py*
+
+Notes:
+
+ #. There is one difference, between the Functest CLI based test case
+ execution compared to the earlier used Bash shell script, which is
+ relevant to point out in troubleshooting scenarios:
+
+ The Functest CLI does **not yet** support the option to suppress
+ clean-up of the generated OpenStack resources, following the execution
+ of a test case.
+
+ Explanation: After finishing the test execution, the corresponding
+ script will remove, by default, all created resources in OpenStack
+ (image, instances, network and security group). When troubleshooting,
+ it is advisable sometimes to keep those resources in case the test
+ fails and a manual testing is needed.
+
+ It is actually still possible to invoke test execution, with suppression
+ of OpenStack resource cleanup, however this requires invocation of a
+ **specific Python script:** '/home/opnfv/repos/functest/ci/run_test.py'.
+ The `OPNFV Functest Developer Guide`_ provides guidance on the use of that
+ Python script in such troubleshooting cases.
+
+Some of the common errors that can appear in this test case are::
+
+ vPing_ssh- ERROR - There has been a problem when creating the neutron network....
+
+This means that there has been some problems with Neutron, even before creating the
+instances. Try to create manually a Neutron network and a Subnet to see if that works.
+The debug messages will also help to see when it failed (subnet and router creation).
+Example of Neutron commands (using 10.6.0.0/24 range for example)::
+
+ neutron net-create net-test
+ neutron subnet-create --name subnet-test --allocation-pool start=10.6.0.2,end=10.6.0.100 \
+ --gateway 10.6.0.254 net-test 10.6.0.0/24
+ neutron router-create test_router
+ neutron router-interface-add <ROUTER_ID> test_subnet
+ neutron router-gateway-set <ROUTER_ID> <EXT_NET_NAME>
+
+Another related error can occur while creating the Security Groups for the instances::
+
+ vPing_ssh- ERROR - Failed to create the security group...
+
+In this case, proceed to create it manually. These are some hints::
+
+ neutron security-group-create sg-test
+ neutron security-group-rule-create sg-test --direction ingress --protocol icmp \
+ --remote-ip-prefix 0.0.0.0/0
+ neutron security-group-rule-create sg-test --direction ingress --ethertype IPv4 \
+ --protocol tcp --port-range-min 80 --port-range-max 80 --remote-ip-prefix 0.0.0.0/0
+ neutron security-group-rule-create sg-test --direction egress --ethertype IPv4 \
+ --protocol tcp --port-range-min 80 --port-range-max 80 --remote-ip-prefix 0.0.0.0/0
+
+The next step is to create the instances. The image used is located in
+*/home/opnfv/functest/data/cirros-0.3.5-x86_64-disk.img* and a Glance image is created
+with the name **functest-vping**. If booting the instances fails (i.e. the status
+is not **ACTIVE**), you can check why it failed by doing::
+
+ nova list
+ nova show <INSTANCE_ID>
+
+It might show some messages about the booting failure. To try that manually::
+
+ nova boot --flavor m1.small --image functest-vping --nic net-id=<NET_ID> nova-test
+
+This will spawn a VM using the network created previously manually.
+In all the OPNFV tested scenarios from CI, it never has been a problem with the
+previous actions. Further possible problems are explained in the following sections.
+
+
+vPing_SSH
+^^^^^^^^^
+This test case creates a floating IP on the external network and assigns it to
+the second instance **opnfv-vping-2**. The purpose of this is to establish
+a SSH connection to that instance and SCP a script that will ping the first
+instance. This script is located in the repository under
+*$REPOS_DIR/functest/functest/opnfv_tests/OpenStack/vPing/ping.sh* and takes an IP as
+a parameter. When the SCP is completed, the test will do an SSH call to that script
+inside the second instance. Some problems can happen here::
+
+ vPing_ssh- ERROR - Cannot establish connection to IP xxx.xxx.xxx.xxx. Aborting
+
+If this is displayed, stop the test or wait for it to finish, if you have used
+the special method of test invocation with specific supression of OpenStack
+resource clean-up, as explained earler. It means that the Container can not
+reach the Public/External IP assigned to the instance **opnfv-vping-2**. There
+are many possible reasons, and they really depend on the chosen scenario. For
+most of the ODL-L3 and ONOS scenarios this has been noticed and it is a known
+limitation.
+
+First, make sure that the instance **opnfv-vping-2** succeeded to get an IP
+from the DHCP agent. It can be checked by doing::
+
+ nova console-log opnfv-vping-2
+
+If the message *Sending discover* and *No lease, failing* is shown, it probably
+means that the Neutron dhcp-agent failed to assign an IP or even that it was not
+responding. At this point it does not make sense to try to ping the floating IP.
+
+If the instance got an IP properly, try to ping manually the VM from the container::
+
+ nova list
+ <grab the public IP>
+ ping <public IP>
+
+If the ping does not return anything, try to ping from the Host where the Docker
+container is running. If that solves the problem, check the iptable rules because
+there might be some rules rejecting ICMP or TCP traffic coming/going from/to the
+container.
+
+At this point, if the ping does not work either, try to reproduce the test
+manually with the steps described above in the vPing common section with the
+addition::
+
+ neutron floatingip-create <EXT_NET_NAME>
+ nova floating-ip-associate nova-test <FLOATING_IP>
+
+
+Further troubleshooting is out of scope of this document, as it might be due to
+problems with the SDN controller. Contact the installer team members or send an
+email to the corresponding OPNFV mailing list for more information.
+
+
+
+vPing_userdata
+^^^^^^^^^^^^^^
+This test case does not create any floating IP neither establishes an SSH
+connection. Instead, it uses nova-metadata service when creating an instance
+to pass the same script as before (ping.sh) but as 1-line text. This script
+will be executed automatically when the second instance **opnfv-vping-2** is booted.
+
+The only known problem here for this test to fail is mainly the lack of support
+of cloud-init (nova-metadata service). Check the console of the instance::
+
+ nova console-log opnfv-vping-2
+
+If this text or similar is shown::
+
+ checking http://169.254.169.254/2009-04-04/instance-id
+ failed 1/20: up 1.13. request failed
+ failed 2/20: up 13.18. request failed

+ failed 19/20: up 217.56. request failed
+ failed 20/20: up 229.58. request failed
+ failed to read iid from metadata. tried 20
+
+it means that the instance failed to read from the metadata service. Contact
+the Functest or installer teams for more information.
+
+NOTE: Cloud-init in not supported on scenarios dealing with ONOS and the tests
+have been excluded from CI in those scenarios.
+
+
+Tempest
+^^^^^^^
+
+In the upstream OpenStack CI all the Tempest test cases are supposed to pass.
+If some test cases fail in an OPNFV deployment, the reason is very probably one
+of the following
+
++-----------------------------+-----------------------------------------------------+
+| Error | Details |
++=============================+=====================================================+
+| Resources required for test | Such resources could be e.g. an external network |
+| case execution are missing | and access to the management subnet (adminURL) from |
+| | the Functest docker container. |
++-----------------------------+-----------------------------------------------------+
+| OpenStack components or | Check running services in the controller and compute|
+| services are missing or not | nodes (e.g. with "systemctl" or "service" commands).|
+| configured properly | Configuration parameters can be verified from the |
+| | related .conf files located under '/etc/<component>'|

+| execution test cases are | Rally in Functest, does not contain all the needed |
+| missing | parameters or some parameters are not set properly. |

+| | in the Functest Docker container. Use the "rally |
+| | deployment list" command in order to check the UUID |
+| | the UUID of the current deployment. |
++-----------------------------+-----------------------------------------------------+
+
+
+When some Tempest test case fails, captured traceback and possibly also the
+related REST API requests/responses are output to the console. More detailed debug
+information can be found from tempest.log file stored into related Rally deployment
+folder.
+
+
+Rally
+^^^^^
+
+The same error causes which were mentioned above for Tempest test cases, may also
+lead to errors in Rally as well.
+
+It is possible to run only one Rally scenario, instead of the whole suite.
+To do that, call the alternative python script as follows::
+
+ python $REPOS_DIR/functest/functest/opnfv_tests/OpenStack/rally/run_rally-cert.py -h
+ usage: run_rally-cert.py [-h] [-d] [-r] [-s] [-v] [-n] test_name
+
+ positional arguments:
+ test_name Module name to be tested. Possible values are : [
+ authenticate | glance | cinder | heat | keystone | neutron |
+ nova | quotas | requests | vm | all ] The 'all' value
+ performs all possible test scenarios
+
+ optional arguments:
+ -h, --help show this help message and exit
+ -d, --debug Debug mode
+ -r, --report Create json result file
+ -s, --smoke Smoke test mode
+ -v, --verbose Print verbose info about the progress
+ -n, --noclean Don't clean the created resources for this test.
+
+For example, to run the Glance scenario with debug information::
+
+ python $REPOS_DIR/functest/functest/opnfv_tests/OpenStack/rally/run_rally-cert.py -d glance
+
+Possible scenarios are:
+ * authenticate
+ * glance
+ * cinder
+ * heat
+ * keystone
+ * neutron
+ * nova
+ * quotas
+ * requests
+ * vm
+
+To know more about what those scenarios are doing, they are defined in directory:
+*$REPOS_DIR/functest/functest/opnfv_tests/OpenStack/rally/scenario*
+For more info about Rally scenario definition please refer to the Rally official
+documentation. `[3]`_
+
+If the flag *all* is specified, it will run all the scenarios one by one. Please
+note that this might take some time (~1,5hr), taking around 1 hour alone to
+complete the Nova scenario.
+
+To check any possible problems with Rally, the logs are stored under
+*/home/opnfv/functest/results/rally/* in the Functest Docker container.
+
+
+Controllers
+-----------
+
+Opendaylight
+^^^^^^^^^^^^
+
+If the Basic Restconf test suite fails, check that the ODL controller is
+reachable and its Restconf module has been installed.
+
+If the Neutron Reachability test fails, verify that the modules
+implementing Neutron requirements have been properly installed.
+
+If any of the other test cases fails, check that Neutron and ODL have
+been correctly configured to work together. Check Neutron configuration
+files, accounts, IP addresses etc.).
+
+
+ONOS
+^^^^
+
+Please refer to the ONOS documentation. `ONOSFW User Guide`_ .
+
+
+Features
+--------
+
+Please refer to the dedicated feature user guides for details.
+
+
+security_scan
