+Functional tests shall be automated (as much as possible) and collected results shall be used to improve the robustness and the reliability of the overall system.
Function tests may cover any domain that could lead to improve the OPNFV solution and define "Telco Cloud" KPI.
* vPing
The 3 first suites are directly inherited from upstream projects.
-vPing, that is already present in Tempest suite, has been developped to provided a basic "hellow world" functional test example.

vIMS, vEPC, vPE, vHGW, vCDN use cases are not considered for first release.
It does not mean that such use cases cannot be tested on OPNFV Arno.
-It means that these use cases have not been integrated in the `Continuous Integration`_ and no specific work (integration or developpment) have been done for R1.

The installation of the OPNFV solution is out of scope of this document but can be found [here_].
In the rest of the document the OPNFV solution would be considered as the System Under Test (SUT).
The installation and configuration of the tools needed to perform the tests will be described in the following sections.
-For release 1, the tools are not automatically installed.

+Actions
+ * start: will prepare the functional testing environment

This script will:
- * Check the environment
- * Install tools
+ * Install Rally environment
+ * Install Tempest
* Retrieve test scenarios
- * Upload cloud images
- * Create temporary test networks
+ * Setup ODL environment
+ * Create temporary neutron private network

+The procedure to set up functional testing environment can be described as follow::
Log on the Jumphost server
- $ wget https://git.opnfv.org/cgit/functest/plain/testcases/config_functest.py
- $ wget https://git.opnfv.org/cgit/functest/plain/testcases/functest.yaml
+ Be sure you are no root
+ Modify and adapt needed parameters in the config_functest.yaml. Follow the instructions below.
Retrieve OpenStack source file (configure your `OpenRC`_ file to let Rally access to your OpenStack, you can either export it from Horizon or build it manually (OpenStack credentials are required)
$ source Your_OpenRC_file
- $ python config_functest.py start
+ $ python config_functest.py -d <Your_functest_directory> start
+
+At the end of the executing, a new directory will be created <functest_repo_directory> with the following structure::
-At the end of the configuration, you shall get the .functest repository::
+ <functest_repo_directory>/ODL
+ <functest_repo_directory>/Rally_repo
+ <functest_repo_directory>/Rally_test
+ <functest_repo_directory>/vPing
+ <functest_repo_directory>/config_functest.yaml

- TODO
+NOTE: the Rally environment will be installed under ~/.rally/ the default Tempest configuration (automatically generated by Rally based on OpenStack credentials) can be found une .rally/tempest/for-deployment-<deployment_id>/tempest.conf
-Please note that you need to install this environment only once. Until the credentials of the System Under Test are not changing, the testing environemnt shall be fine.

+HOWTO configure config_functest.yaml:
+
+Do not change the directories structure
+ * image_name: name of the image that will be created in Glance
+ * image_url: URL of the image to be downloaded
+ * image_disk_format: glance image disk format (raw, qcow2, ...)
+
+ * neutron_private_net_name: name of an OpenStack private network. If not existing, it will be created
+ * neutron_private_subnet_name: private subnet network to be created if not existing
+ * neutron_private_subnet_cidr: range of the private subnet.
+ * neutron_private_subnet_start: start IP
+ * neutron_private_subnet_end: end IP
+ * neutron_router_name: name of the router between the private and the public networks
+
+ * ping_timeout: time out of the vPing test case
+ * vm_flavor: name of the flavor used to create the VMs
