4 Overview of the Functest suites
5 ===============================
6
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
10 infrastructure.
11
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).

157
158 As shown in the above table, Functest is structured into different 'domains',
159 'tiers' and 'test cases'. Each 'test case' usually represents an actual
160 'Test Suite' comprised -in turn- of several test cases internally.
161
162 Test cases also have an implicit execution order. For example, if the early
163 'healthcheck' Tier testcase fails, or if there are any failures in the 'smoke'
164 Tier testcases, there is little point to launch a full testcase execution round.
165
166 An overview of the Functest Structural Concept is depicted graphically below:
167
168 .. figure:: ../images/concepts_mapping_final.png
169    :align: center
170    :alt: Functest Concepts Structure
171
172 Some of the test cases are developed by Functest team members, whereas others
173 are integrated from upstream communities or other OPNFV projects. For example,
174 `Tempest <http://docs.openstack.org/developer/tempest/overview.html>`_ is the
175 OpenStack integration test suite and Functest is in charge of the selection,
176 integration and automation of those tests that fit suitably to OPNFV.
177
178 The Tempest test suite is the default OpenStack smoke test suite but no new test
179 cases have been created in OPNFV Functest.
180
181 The results produced by the tests run from CI are pushed and collected into a
182 NoSQL database. The goal is to populate the database with results from different
183 sources and scenarios and to show them on a `Functest Dashboard`_. A screenshot
184 of a live Functest Dashboard is shown below:
185
186 .. figure:: ../images/FunctestDashboard.png
187    :align: center
188    :alt: Functest Dashboard
189
190
191 There is no real notion of Test domain or Test coverage. Basic components
192 (VIM, SDN controllers) are tested through their own suites. Feature projects
193 also provide their own test suites with different ways of running their tests.
194
195 vIMS test case was integrated to demonstrate the capability to deploy a
196 relatively complex NFV scenario on top of the OPNFV infrastructure.
197
198 Functest considers OPNFV as a black box. As of Colorado release the OPNFV
199 offers a lot of potential combinations:
200
201   * 3 controllers (OpenDaylight, ONOS, OpenContrail)
202   * 4 installers (Apex, Compass, Fuel, Joid)
203
204 Most of the tests are runnable by any combination, but some tests might have
205 restrictions imposed by the utilized installers or due to the available
206 deployed features. The system uses the environment variables (INSTALLER_IP and
207 DEPLOY_SCENARIO) to automatically determine the valid test cases, for each given
208 environment.
209
210 In the Colorado OPNFV System release a convenience Functest CLI utility is also
211 introduced to simplify setting up the Functest evironment, management of the
212 OpenStack environment (e.g. resource clean-up) and for executing tests.
213 The Functest CLI organised the testcase into logical Tiers, which contain in
214 turn one or more testcases. The CLI allows execution of a single specified
215 testcase, all test cases in a specified Tier, or the special case of execution
216 of **ALL** testcases. The Functest CLI is introduced in more detail in the
217 section `Executing the functest suites`_ of this document.
