 Description of the test cases
------------------------------
+=============================
+
+Functest is an OPNFV project dedicated to functional testing.
+In the continuous integration, it is launched after a fresh installation of an OPNFV solution to verify the basic functions.
+
+Functest includes several test suites that usually include several test cases.
+Some are developped within the Functest project, some in dedicated feature projects.
+
+The current list of test suites can be distributed in 3 main domains:
+

+
+
+Most of the test suites are developped upstream, Functest is in charge of the integration in OPNFV.
+Tempest `[2]`_, for example, is the OpenStack reference test suite.
+
+In Functest we customized the list of tests within Tempest but do not created our own test cases.
+Some OPNFV feature projects (.e.g. SDNVPN) may create tempest scenario upstream that are integrated in our Tempest through our configuration.
+
+The test results are pushed into a test result database (when possible) in order to build a test dashboard.
+
+There is no real notion of Test domain or Test coverage yet, we tried to cover basic components such as VIM and controllers and integrate the tests of the feature projects.
+
+The vIMS test case was also 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. OPNFV, since Brahmaputra, offers lots of possible combination (3 controllers, 4 installers).
+
+However most of the tests (except obviously those dedicated to a specific controller) shall be runnable on any configuration.
+
+The different scenarios are described in the section hereafter.

 This example, using OpenStack Python clients can be considered as an "Hello World" example and may be modified for future use.
+It is the first basic example, it must work on any configuration.
+
+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 batteries of tests for OpenStack API validation, Scenarios, and other specific tests useful in validating an OpenStack deployment.
+
+We use Rally `[3]`_ to run Tempest suite.
+The tempest.conf configuration file is automatically generated by Rally then the Tempest suite is run, each test duration is measured.
+
+We considered the smoke test suite for Arno. For Brahmaputra, we decided to customize the list of test cases using the --tests-file option introduced in Rally in version 0.1.2.
+
+The custom list is available on the Functest repo `[4]`_ and contains more than 200 test cases. 
+This list contains tempest test cases chosen for Functest deployment.
+It consists of two main parts:
+
+  1) Set of tempest smoke test cases
+  2) Set of test cases from DefCore list (https://wiki.openstack.org/wiki/Governance/DefCoreCommittee)
+
+The goal of this test is to check the basic OpenStack functionalities on an OPNFV fresh installation.
+
+
+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 test the different modules of OpenStack and get significant figures that could help us to define telco Cloud KPI.
+
+The OPNFV scenarios are based on the collection of the existing Rally scenarios:
+ * authenticate
+ * cinder
+ * glance
+ * heat
+ * keystone
+ * neutron
+ * nova
+ * quotas
+ * requests
+ * vm
+
+For Brahmaputra, we integrated the rally certification feature introduced in Rally 0.1.1.
+
+SLA
 
-In SR1, some code has been added in order to push the results (status and duration) into a centralized test result database.
 
 SDN Controllers
 ===============
 
+Brahmaputra introduces new SDN controllers in addition of odl already integrated in Arno.
+There are currently 3 possible controllers:
+
+ * odl
+ * onos
+ * opencontrail

 OpenDaylight
 ------------
 
-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.

+The goal of this test suite consists in:
+ * deploying 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
-======================
 
-.. _Rally: https://wiki.openstack.org/wiki/Rally
+==============
+Manual testing
+==============
 
-Rally bench test suite consist in a suite of light performance tests on some of the OpenStack components.
+Once you have installed Functest docker file `[1]`_, and configured the system (though /home/opnfv/repos/functest/docker/prepare_env.sh script), you are ready to run the tests.
 
-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.
+The script run_tests.sh has several options::
 
-The OPNFV scenarios are based on the collection of the existing Rally_ scenarios:
- * authenticate
- * cinder
- * nova
- * requests
- * glance
- * keystone
- * neutron
- * quotas
+    ./run_tests.sh -h
+    Script to trigger the tests automatically.
 
+    usage:
+        bash run_tests.sh [--offline] [-h|--help] [-t <test_name>]
 
-This test suite provides performance information on VIM (OpenStack) part.
+    where:
+        -o|--offline      optional offline mode (experimental)
+        -h|--help         show this help text
+        -r|--report       push results to database (false by default)
+        -t|--test         run specific set of tests
+          <test_name>     one or more of the following: vping,odl,rally,tempest,vims. Separated by comma.
 
-No SLA were defined for release 1, we just consider whether the tests are passed or failed.
+    examples:
+        run_tests.sh
+        run_tests.sh --test vping,odl
+        run_tests.sh --offline -t tempest,rally
 
-In the future SLA shall be defined (e.g. accepting booting time for a given image with a given flavour).
+The -o option can be used to run the container offline (in case you are in a summit where there is no Internet connection...). It is an experimental option.
 
-Through its integration in Continuous Integration, the evolution of the performance of these tests shall also be considered.
+The -r option is used by the Continuous Integration in order to push the test results into a test collection database, see in next section for details. In manual mode, you must not use it, your try will be anyway probably rejected as your POD must be declared in the database to collect the data.
 
-Feature projects
-================
+The -t option can be used to specify the list of test you want to launch, by default Functest will try to launch all its test suites in the following order vPing, odl, Tempest, vIMS, Rally. You may launch only one single test by using -t <the test you want to launch>
 
---------------
-Manual testing
---------------
+Please note that Functest includes cleaning mechanism to remove everything except what was present after a fresh install. If you create VM, tenants, networks then launch Functest, there is a risk to remove elements. Be carefull or comment the cleaning phase in run_test.sh (comment call to clean_openstack.py). However, be aware that Tempest and rally triggers the creation of lots of components that are not always properly cleaned, this function has been set to keep the system as clean as possible after a full Functest run.
+
+You may also add you own test by adding a section into the function run_test()
 
-------------------
+
+=================
 Automated testing
-------------------
+=================
+
+As mentioned in `[1]`, the prepare-env.sh and run_test.sh can be executed within the container from jenkins. 2 jobs have been created, one to run all the test and one that allows testing test suite by test suite. You thus just have to launch the acurate jenkins job on the target lab, all the tests shall be automatically run.

+==========================
+Functest in test Dashboard
+==========================
+
+The OPNFV testing group created a test collection database to collect the test results from CI.
+Any lab integrated in CI can push the results to this database.
+
+The idea is to centralize the resultes and created a dashboard to give a high level overview of the test activities.
+
