4 Overview of the Functest suites
5 ===============================
7 Functest is the OPNFV project primarily targeting function testing.
8 In the Continuous Integration pipeline, it is launched after an OPNFV fresh
9 installation to validate and verify the basic functions of the
12 The current list of test suites can be distributed over 4 main domains: VIM
13 (Virtualised Infrastructure Manager), Controllers (i.e. SDN Controllers),
14 Features and VNF (Virtual Network Functions).
16 +-------------+---------------+----------------+----------------------------------+
17 | Domain | Tier | Test case | Comments |

21 | | smoke | vPing_SSH | NFV "Hello World" using an SSH |
22 | | | | connection to a destination VM |
23 | | | | over a created floating IP |
24 | | | | address on the SUT Public / |
25 | | | | External network. Using the SSH |
26 | | | | connection a test script is then |
27 | | | | copied to the destination |
28 | | | | VM and then executed via SSH. |
29 | | | | The script will ping another |
30 | | | | VM on a specified IP address over|
31 | | | | the SUT Private Tenant network. |

33 | | | vPing_userdata | Uses Ping with given userdata |
34 | | | | to test intra-VM connectivity |

149 As shown in the above table, Functest is structured into different 'domains',
150 'tiers' and 'test cases'. Each 'test case' usually represents an actual
151 'Test Suite' comprised -in turn- of several test cases internally.
153 Test cases also have an implicit execution order. For example, if the early
154 'healthcheck' Tier testcase fails, or if there are any failures in the 'smoke'
155 Tier testcases, there is little point to launch a full testcase execution round.
157 An overview of the Functest Structural Concept is depicted graphically below:
159 .. figure:: ../images/concepts_mapping_final.png
161 :alt: Functest Concepts Structure
163 Some of the test cases are developed by Functest team members, whereas others
164 are integrated from upstream communities or other OPNFV projects. For example,
165 `Tempest <http://docs.openstack.org/developer/tempest/overview.html>`_ is the
166 OpenStack integration test suite and Functest is in charge of the selection,
167 integration and automation of those tests that fit suitably to OPNFV.
169 The Tempest test suite is the default OpenStack smoke test suite but no new test
170 cases have been created in OPNFV Functest.
172 The results produced by the tests run from CI are pushed and collected into a
173 NoSQL database. The goal is to populate the database with results from different
174 sources and scenarios and to show them on a `Functest Dashboard`_. A screenshot
175 of a live Functest Dashboard is shown below:
177 .. figure:: ../images/FunctestDashboard.png
179 :alt: Functest Dashboard
182 There is no real notion of Test domain or Test coverage. Basic components
183 (VIM, SDN controllers) are tested through their own suites. Feature projects
184 also provide their own test suites with different ways of running their tests.
186 vIMS test case was integrated to demonstrate the capability to deploy a
187 relatively complex NFV scenario on top of the OPNFV infrastructure.
189 Functest considers OPNFV as a black box. As of Colorado release the OPNFV
190 offers a lot of potential combinations:
192 * 3 controllers (OpenDaylight, ONOS, OpenContrail)
193 * 4 installers (Apex, Compass, Fuel, Joid)
195 Most of the tests are runnable by any combination, but some tests might have
196 restrictions imposed by the utilized installers or due to the available
197 deployed features. The system uses the environment variables (INSTALLER_IP and
198 DEPLOY_SCENARIO) to automatically determine the valid test cases; for each given
201 In the Colorado OPNFV System release a convenience Functest CLI utility is also
202 introduced to simplify setting up the Functest evironment, management of the
203 OpenStack environment (e.g. resource clean-up) and for executing tests.
204 The Functest CLI organised the testcase into logical Tiers, which contain in
205 turn one or more testcases. The CLI allow execution of a single specified
206 testcase, all test cases in a specified Tier, or the special case of execution
207 of **ALL** testcases. The Functest CLI is introduced in more detail in the
208 section `Executing the functest suites`_ of this document.
