-Description of the test cases
+Overview of the test suites
=============================
-Functest is an OPNFV project dedicated to functional testing.
-In the continuous integration, it is launched after an OPNFV fresh installation.
-The Functest target is to verify the basic functions of the infrastructure.
-
-Functest includes different test suites which several test cases within.
-Test cases are developed in Functest and in feature projects.
+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 in 3 main domains::

| Infrastructure +----------------+-------------------------------------------+
- | Manager) | Rally scenario | OpenStack testing tool testing OpenStack |

-Most of the test suites are developed upstream.
-For example, `Tempest <http://docs.openstack.org/developer/tempest/overview.html>`_ is the
-OpenStack integration test suite.
-Functest is in charge of the integration of different functional test suites.
+Functest includes different test suites with several test cases within. Some
+of the tests 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 the tests that fit in OPNFV.
The Tempest suite has been customized but no new test cases have been created.
-Some OPNFV feature projects (e.g. SDNVPN) have created Tempest tests cases and
-pushed to upstream.
+Some OPNFV feature projects (e.g. SDNVPN) have written some Tempest tests cases
+and pushed upstream to be used by Functest.
-The tests run from CI are pushed into a database.
-The goal is to populate the database with results and to show them on a Test
-Dashboard.
+The results produced by the tests run from CI are pushed and collected in a NoSQL
+database. The goal is to populate the database with results from different sources
+and scenarios and to show them on a Dashboard.
-There is no real notion of Test domain or Test coverage yet.
-Basic components (VIM, controllers) are tested through their own suites.
-Feature projects also provide their own test suites.

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.
-OPNFV, since Brahmaputra, offers lots of possible combinations:
+OPNFV, since the Brahmaputra release, offers lots of potential combinations:
* 3 controllers (OpenDayligh, ONOS, OpenContrail)
* 4 installers (Apex, Compass, Fuel, Joid)
-However most of the tests shall be runnable on any configuration.
+Most of the tests are runnable on any combination, but some others might have
+restrictions imposed by the installers or the available deployed features.
============
The goal of this documents is to describe the Functest test cases as well as
-provide a procedure about how to execute (or launch) them.

-We use Rally `[3]`_ to run Tempest suite.
-Rally generates automatically tempest.conf configuration file.
-Before running actual test cases Functest creates needed resources.
-Needed parameters are updated in the configuration file.
-When the Tempest suite is run, each test duration is measured.
-The full console output is stored in the tempest.log file.

several options::

usage:

where:
-h|--help show this help text

-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.
+The *-r* option is used by the OPNFV Continuous Integration automation mechanisms
+in order to push the test results into the NoSQL results collection database.
+This database is read only for a regular user given that it needs special rights
+and special conditions to push data.
-The *-n* option is used for preserving all the existing OpenStack resources after
-execution test cases.
+The *-t* option can be used to specify the list of a desired test to be launched,
+by default Functest will launch all the test suites in the following order:
+vPing, Tempest, vIMS, Rally.
-The *-t* option can be used to specify the list of test you want to launch, by

-vPing, odl, Tempest, vIMS, Rally.
-You may launch only one single test by using *-t <the test you want to launch>*.
+A single or set of test may be launched at once using *-t <test_name>* specifying
+the test name or names separated by commas in the following list:
+*[vping,vping_userdata,odl,rally,tempest,vims,onos,promise]*.
-Within Tempest test suite you can define which test cases you want to execute in
-your environment by editing test_list.txt file before executing *run_tests.sh*
-script.
+The *-n* option is used for preserving all the possible OpenStack resources created
+by the tests after their execution.
Please note that Functest includes cleaning mechanism in order to remove
-everything except what was present after a fresh install.
-If you create your own VMs, tenants, networks etc. and then launch Functest,
-they all will be deleted after executing the tests. Use the *--no-clean* option with
-run_test.sh in order to preserve all the existing resources.
-However, be aware that Tempest and Rally create of lot of resources (users,
+all the VIM resources except what was present before running any test. The script
+*$repos_dir/functest/testcases/VIM/OpenStack/CI/libraries/generate_defaults.py*
+is called once by *prepare_env.sh* when setting up the Functest environment
+to snapshot all the OpenStack resources (images, networks, volumes, security groups,
+tenants, users) so that an eventual cleanup does not remove any of this defaults.
+
+The script
+*$repos_dir/functest/testcases/VIM/OpenStack/CI/libraries/clean_openstack.py*
+is normally called after a test execution if the *-n* is not specified. 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 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 if this
+flag is not specified in the *run_tests.sh* command.
+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
-cleaning 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().
+Within the Tempest test suite it is possible to define which test cases to execute
+by editing *test_list.txt* file before executing *run_tests.sh* script. This file
+is located in *$repos_dir/functest/testcases/VIM/OpenStack/CI/custom_tests/test_list.txt*
+Although *run_tests.sh* 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/testcases/vPing/vPing.py -d
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.
+As mentioned in `[1]`, the *prepare-env.sh* and *run_test.sh* can be called within
+the container from Jenkins. There are 2 jobs that automate all the manual steps
+explained in the previous section. One job runs all the tests and the other one allows testing
+test suite by test suite specifying the test name. The user might use one or
+the other job to execute the desired test suites.
+
+One of the most challenging task in the Brahmaputra 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 order of execution is also described in the Functest configuration file::
