-In SR1, some code has been added in order to push the results (status and duration) into a centralized test result database.
+============
+
+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.
-SDN Controllers
-===============
-OpenDaylight
-------------
+Tempest
+^^^^^^^
-The ODL suite consists in a set of basic tests inherited from ODL project. The suite tests the creation and deletion of network, subnet, port though OpenDaylight and Neutron.
+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:
-The list of tests can be described as follow:
- * Restconf.basic: Get the controller modules via Restconf
- * Neutron.Networks
+ * OpenStack API validation
+ * Scenarios
+ * Other specific tests useful in validating an OpenStack deployment
- * Check OpenStack Networks :: Checking OpenStack Neutron for known networks
- * Check OpenDaylight Networks :: Checking OpenDaylight Neutron API
- * Create Network :: Create new network in OpenStack
- * Check Network :: Check Network created in OpenDaylight
- * Neutron.Networks :: Checking Network created in OpenStack are pushed
+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.
- * Neutron.Subnets
+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.
- * Check OpenStack Subnets :: Checking OpenStack Neutron for known Subnets
- * Check OpenDaylight subnets :: Checking OpenDaylight Neutron API
- * Create New subnet :: Create new subnet in OpenStack
- * Check New subnet :: Check new subnet created in OpenDaylight
- * Neutron.Subnets :: Checking Subnets created in OpenStack are pushed
+The Tempest testcases are distributed accross two
+Tiers:
- * Neutron.Ports
+ * Smoke Tier - Test Case 'tempest_smoke_serial'
+ * Components Tier - Test case 'tempest_full_parallel'
- * Check OpenStack ports :: Checking OpenStack Neutron for known ports
- * Check OpenDaylight ports :: Checking OpenDaylight Neutron API
- * Create New Port :: Create new port in OpenStack
- * Check New Port :: Check new subnet created in OpenDaylight
- * Neutron.Ports :: Checking Port created in OpenStack are pushed
+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.
- * Delete Ports
+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.
- * Delete previously created subnet in OpenStack
- * Check subnet deleted in OpenDaylight
- * Check subnet deleted in OpenStack
- * Delete network
+Rally bench test suites
+^^^^^^^^^^^^^^^^^^^^^^^
- * Delete previously created network in OpenStack
- * Check network deleted in OpenDaylight
- * Check network deleted in OpenStack
+Rally `[3]`_ is a benchmarking tool that answers the question:
+*How does OpenStack work at scale?*
-ONOS
-----
-TODO
+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
-OpenContrail
-------------
+A basic SLA (stop test on errors) has been implemented.
-TODO
+The Rally testcases are distributed accross two Tiers:
+ * Smoke Tier - Test Case 'rally_sanity'
+ * Components Tier - Test case 'rally_full'
-Tempest
-=======
+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.
-.. _Tempest: http://docs.openstack.org/developer/tempest/overview.html
+connection check
+^^^^^^^^^^^^^^^^
+Connection_check consists in 9 test cases (test duration < 5s) checking the
+connectivity with Glance, Keystone, Neutron, Nova and the external network.
-Tempest_ is the OpenStack Integration Test Suite. We use Rally to run Tempest suite.
+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)
-The Tempest.conf configuration file is automatically generated by Rally then the Tempest suite is run, each test duration is measured.
+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)
-We considered the smoke test suite for Arno.
+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:

+
+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
+---
-The goal of this test is to to check the basic OpenStack functionality on a fresh installation.
vIMS
-====
+^^^^
+The IP Multimedia Subsystem or IP Multimedia Core Network Subsystem (IMS) is an
+architectural framework for delivering IP multimedia services.
-TODO
+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.
-Rally bench test suite
-======================
+The goal of this test suite consists of:
-.. _Rally: https://wiki.openstack.org/wiki/Rally
+ * 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
-Rally bench test suite consist in a suite of light performance tests on some of the OpenStack components.
+The Clearwater architecture is described as follows:
-The goal of this test suite is to test the different modules of OpenStack and get significant figures that could help us to define telco Cloud KPI.
+.. figure:: ../images/clearwater-architecture.png
+ :align: center

-The OPNFV scenarios are based on the collection of the existing Rally_ scenarios:
- * authenticate
- * cinder
- * nova
- * requests
- * glance
- * keystone
- * neutron
- * quotas
+parser
+^^^^^^
-This test suite provides performance information on VIM (OpenStack) part.
+See parser user guide for details: `[12]`_
-No SLA were defined for release 1, we just consider whether the tests are passed or failed.
-In the future SLA shall be defined (e.g. accepting booting time for a given image with a given flavour).
+.. include:: ./runfunctest.rst
-Through its integration in Continuous Integration, the evolution of the performance of these tests shall also be considered.
