Introduction
============
-The goal of this documents is to describe the Functest test cases as well as
-provide a procedure about how to execute them.
+The goal of this document is to describe the OPNFV Functest test cases and to
+provide a procedure to execute them. In the OPNFV Colorado system release,
+a Functest CLI utility is introduced for easier execution of test procedures.
+
+An overview presentation has been created for the first OPNFV Summit `[4]`_.
-A presentation has been created for the first OPNFV Summit `[4]`_.
+This document is a continuation of the OPNFV Functest Configuration Guide `[1]`_.
-It is assumed that Functest container has been properly installed `[1]`_.
+**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.

-The different scenarios are described in the section hereafter.
+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'
+is 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
+
+vPing_ssh
^^^^^^^^^
-Given the script 'ping.sh'::
+Given the script **ping.sh**::
#!/bin/sh
while true; do
sleep 1
done
-The goal of this test is described as follows::
- vPing test case
+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 | |
| | to VM2 | |
| +------------------->| |
| | | |
- | | Stablish SSH | |
+ | | Establish SSH | |
| | connection to VM2 | |
| | through floating IP| |
| +------------------->| |
| | | |
| | If ping: | |
| | exit OK | |
- | | else (timeout) | |
+ | | else (timeout): | |
| | exit Failed | |

+-------------+ +-------------+
This test can be considered as an "Hello World" example.
-It is the first basic use case which shall work on any deployment.
+It is the first basic use case which **must** work on any deployment.
vPing_userdata
^^^^^^^^^^^^^^
-The goal of this test can be described as follows::
+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
+-------------+ +-------------+
| | | |
+-------------+ +-------------+
-This scenario is similar to the previous one but it uses cloud-init (nova
-metadata service) instead of floating IPs and SSH connection. When the second VM
-boots it will execute the script automatically and the ping will be detected
-capturing periodically the output in the console-log of the second VM.
+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 batteries of tests for:
+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 and
-updates the appropriate parameters to the configuration file.
+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 in the tempest.log file for further analysis.
+console output is stored to a *log* file for further analysis.
-As an addition of Arno, Brahmaputra runs a customized set of Tempest test cases.
-The list is specificed through *--tests-file* when running Rally.
-This option has been introduced in Rally in version 0.1.2.
+The Tempest testcases are distributed accross two
+Tiers:
-The customized test list is available in the Functest repo `[4]`_.
-This list contains more than 200 Tempest test cases and can be divided
-into two main sections:
+ * Smoke Tier - Test Case 'tempest_smoke_serial'
+ * Openstack Tier - Test case 'tempest_full_parallel'
- 1) Set of tempest smoke test cases
- 2) Set of test cases from DefCore list `[8]`_
+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
-different OpenStack components on an OPNFV fresh installation using
-the corresponding REST API interfaces.

-vIMS
-^^^^
-The goal of this test suite consists of:
+security_scan
+^^^^^^^^^^^^^
- * 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
+Security Scanning, is a project to insure security compliance and vulnerability
+checks, as part of an automated CI / CD platform delivery process.
-The Clearwater architecture is described as follows:
+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.
-.. figure:: ../images/clearwater-architecture.png
- :align: center
- :alt: vIMS architecture
+The SCAP content itself, is then consumed and run using an upstream opensource tool
+known as OpenSCAP[7].
-Two types of information are stored in the Test Database:
+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 duration of each step (orchestion deployment, VNF deployment and test)
- * the test results
+The current work flow is as follows:
-The deployment of a complete functional VNF allows the test of most of the
-essential functions needed for a NFV platform.
+ * 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.
-Promise
-^^^^^^^
+At present, only the Apex installer is supported, with support for other installers due
+within D-release.
-Promise provides a basic set of test cases as part of Brahmaputra.
-The available 33 test cases can be grouped into 7 test suites:
- #. Add a new OpenStack provider into resource pool: Registers
- OpenStack into a new resource pool and adds more capacity associated
- with this pool.
+VNF
+---
+
- #. Allocation without reservation: Creates a new server in OpenStack
- and adds a new allocation record in Promise shim-layer.
+vIMS
+^^^^
+The IP Multimedia Subsystem or IP Multimedia Core Network Subsystem (IMS) is an
+architectural framework for delivering IP multimedia services.
- #. Allocation using reservation for immediate use: Creates a resource
- reservation record with no start/end time and immediately creates a new
- server in OpenStack and add a new allocation record in Promise
- shim-layer.
+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.
- #. Reservation for future use: Creates a resource reservation record
- for a future start time, queries, modifies and cancels the newly created
- reservation.
+The goal of this test suite consists of:
- #. Capacity planning: Decreases and increases the available capacity
- from a provider in the future and queries the available collections and
- utilizations.
+ * 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
- #. Reservation with conflict: Tries to create reservations for
- immediate and future use with conflict.
+The Clearwater architecture is described as follows:
- #. Cleanup test allocations: Destroys all allocations in OpenStack.
