============
Introduction
============

Functest is a project dealing with functional testing.
Functest produces its own internal test cases but can also be considered
as a framework to support feature project testing suite integration.
Functest developed a test API and defined a Test collection framework
that can be used by any OPNFV project.

Therefore there are many ways to contribute to Functest. You can:

 * develop new internal test cases
 * integrate the tests from your feature project
 * develop the framework to ease the integration of external test cases
 * develop the API / Test collection framework
 * develop dashboards or automatic reporting portals

This document describes how, as a developer, you may interact with the
Functest project. The first section details the main working areas of
the project. The Second part is a list of "How to" to help you to join
the Functest family whatever your field of interest is.


========================
Functest developer areas
========================


Functest High level architecture
================================

Functest is project delivering a test container dedicated to OPNFV.
It includes the tools, the scripts and the test scenarios.

Functest can be described as follow::

 +----------------------+
 |                      |
 |   +--------------+   |                  +-------------------+
 |   |              |   |    Public        |                   |
 |   | Tools        |   +------------------+      OPNFV        |
 |   | Scripts      |   |                  | System Under Test |
 |   | Scenarios    |   +------------------+                   |
 |   |              |   |    Management    |                   |
 |   +--------------+   |                  +-------------------+
 |                      |
 |    Functest Docker   |
 |                      |
 +----------------------+

Functest internal test cases
============================
The internal test cases in Colorado are:

 * vping_ssh
 * vping_userdata
 * odl
 * tempest_smoke_serial
 * rally_sanity
 * tempest_full_parallel
 * rally_full
 * vims

By internal, we mean that this particular test cases have been
developped by functest contributors and the associated code is hosted in
the Functest repository.
The structure of this repository is detailed in `[1]`_.
The main internal test cases are int the testcases subfolder of the
repository, the internal test cases are:

 * Controllers: odl, onos
 * OpenStack: vping_ssh, vping_userdata, tempest_*, rally_*
 * vIMS: vims

If you want to create a new test cases you will have to create a new
folder under the testcases directory

Functest external test cases
============================
The external tescases are:

 * promise
 * doctor
 * onos
 * bgpvpn
 * copper
 * moon
 * security_scan
 * sfc-odl
 * sfc-onos


Note that security_scan has been bootstraped in Functest but will be
considered as an external test cases as soon as it will get its own
repository.

The code to run these test cases may be directly in the repository of
the project. We have also a features sub directory under testcases
directory that may be used (it can be usefull if you want to reuse
Functest library).


Functest framework
==================

Functest can be considered as a framework.
Functest is release a a docker file, including tools, scripts and a CLI
to prepare the environement and run tests.
It simplifies the integration of external test suite in CI pipeline
and provide commodity tools to collect and display results.

Since Colorado, test categories also known as tiers have been created to
group similar tests, provide consistant sub-lists and at the end optimize
test duration for CI (see How To section).

see `[2]`_ for details.

Test API
========

The OPNFV testing group created a test collection database to collect
the test results from CI.
Any test project running on any lab integrated in CI can push the
results to this database.
This database can be used afterwards to see the evolution of the tests
and compare the results versus the installers, the scenario or the labs.

You can find more information about the dashboard from Testing Dashboard
wiki page `[3]`_.

Overall Architecture
====================
The Test result management can be summarized as follows::

Test API description
====================
The Test API is used to declare pods, projects, test cases and test
results. An additional method dashboard has been added to post-process
the raw results in release Brahmaputra.

The data model is very basic, 4 objects are created:

  * Pods
  * Projects
  * Testcases
  * Results

Pods::

  {
    "id": <ID>,
    "details": <URL description of the POD>,
    "creation_date": "YYYY-MM-DD HH:MM:SS",
    "name": <The POD Name>,
    "mode": <metal or virtual>,
    "role": <ci-pod or community-pod or single-node>
  },

Projects::

  {
    "id": <ID>,
    "name": <Name of the Project>,
    "creation_date": "YYYY-MM-DD HH:MM:SS",
    "description": <Short description>
  },

Testcases::

  {
    "id": <ID>,
    "name":<Name of the test case>,
    "project_name":<Name of belonged project>,
    "creation_date": "YYYY-MM-DD HH:MM:SS",
    "description": <short description>,
    "url":<URL for longer description>
  },

Results::

  {
    "_id": <ID>,
    "case_name": <Reference to the test case>,
    "project_name": <Reference to project>,
    "pod_name": <Reference to POD where the test was executed>,
    "installer": <Installer Apex or Compass or Fuel or Joid>,
    "version": <master or Colorado or Brahmaputra>,
    "start_date": "YYYY-MM-DD HH:MM:SS",
    "stop_date": "YYYY-MM-DD HH:MM:SS",
    "build_tag": <such as "jenkins-functest-fuel-baremetal-daily-master-108">,
    "scenario": <Scenario on which the test was executed>,
    "criteria": <PASS or FAILED>,
    "trust_indicator": <0~1>
  }

The API can described as follows. For detailed information, please go to
http://testresults.opnfv.org/test/swagger/spec.html

Authentication: opnfv/api@opnfv

Please notes that POST/DELETE/PUT operations for test or study purpose via
swagger website is not allowed, because it will change the real data in
the database.

Dashboard
=========

Dashboard is used to provide a consistant view of the results collected
in CI.
The results with dashboard method are post-processed from raw results.
Please note that dashboard results are not stored. Only raw results are
stored.

Release Brahmaputra
-------------------

Dashboard url: http://testresults.opnfv.org/dashboard/

Release Colorado
----------------
Since Colorado, it was decided to adopt ELK framework. Mongo DB results
are extracted to feed Elasticsearch database (`[7]`_).

Dashboard url: http://testresults.opnfv.org/kibana_dashboards/

Credentials for a guest account: opnfvuser/kibana


Automatic reporting
===================

OPNFV release is scenario centric. An automatic reporting page has been
created in order to provide a consistant view of the scenarios.
In this page each scenario is evaluated according to test criteria.
The code for the automatic reporting is available at `[8]`_.

Every day, we collect the results from the centralized database and, per
scenario we calculate a score. This score is the addition of individual
tests considered on the last 10 runs according to a defined criteria.

If we consider for instance a scenario os-odl_l2-nofeature-ha, we will
consider for the scoring all the runnable tests from the first test
categories (tiers healthcheck, smoke, controller and feature)
corresponding to this scenario.

 +---------------------+---------+---------+---------+---------+

All the testcases listed in the table are runnable on
os-odl_l2-nofeature scenarios.
If no results are available or if all the results are failed, the test
case get 0 point.
If it was succesfull at least once but no anymore during the 4 runs,
the case get 1 point (it worked once).
If at least 3 of the last 4 runs were successful, the case get 2 points.
If the last 4 runs of the test are successful, the test get 3 points.

In the example above, the target score for fuel/os-odl_l2-nofeature-ha
is 3x6 = 18 points.

The scenario is validated per installer when we got 3 points for all
individual test cases (e.g 18/18).
Please note that complex or long duration tests are not considered for
the scoring. Such cases will be also get points, but these points will
be indicative and not used for the scenario validation.

A web page is automatically generated every day to display the status.
This page can be found at `[9]`_. For the status, click on Status menu,
you may also get feedback for vims and tempest_smoke_serial test cases.

Any validated scenario is stored in a local file on the web server. In
fact as we are using a sliding windows to get results, it may happen
that a successfull scenarios is not more run (because considered as
stable)and then the number of iterations (need 4) would not be
sufficient to get the green status.

Please note that other test cases e.g. sfc_odl, bgpvpn, moon) need also
ODL configuration addons and as a consequence specific scenario.
There are not considered as runnable on the generic odl_l2 scenario.

How Functest works?
===================

The installation and configuration of the Functest docker image is
described in `[1]`_.

The procedure to start tests is described  in `[2]`_


How can I contribute to Functest?
=================================

If you are already a contributor of any OPNFV project, you can
contribute to functest. If you are totally new to OPNFV, you must first
create your Linux Foundation account, then contact us in order to
declare you in the repository database.

We distinguish 2 levels of contributors: the standard contributor can
push patch and vote +1/0/-1 on any Functest patch. The commitor can vote
-2/-1/0/+1/+2 and merge.
Functest commitors are promoted by the Functest contributors.


Where can I find some help to start?
====================================

This guide is made for you. You can also have a look at the project wiki
page `[10]`_.
There are references on documentation, video tutorials, tips...

You can also directly contact us by mail with [Functest] prefix at
opnfv-tech-discuss@lists.opnfv.org or on the IRC chan #opnfv-functest.


What kind of testing do you do in Functest?
===========================================

Functest is focusing on Functional testing. The results must be PASS or
FAILED. We do not deal with performance and/or qualification tests.
We consider OPNFV as a black box and execute our tests from the jumphost
according to Pharos reference technical architecture.

Upstream test suites are integrated (Rally/Tempest/ODL/ONOS,...).
If needed Functest may bootstrap temporarily testing activities if they
are identified but not covered yet by an existing testing project (e.g
security_scan before the creation of the security reporistory)


How test constraints are defined?
=================================

Test constraints are defined according to 2 paramaters:

 * the scenario (DEPLOY_SCENARIO env variable)
 * the installer (INSTALLER_TYPE env variable)

A scenario is a formal description of the system under test.
The rules to define a scenario are described in `[4]`_

These 2 constraints are considered to determinate if the test is runnable
or not (e.g. no need to run onos suite on odl scenario).

In the test declaration for CI, the test owner shall indicate these 2
constraints. The file testcases.yaml `[5]`_ must be patched in git to
include new test cases. A more elaborated system based on template is
planned for next releases

For each dependency, it is possible to define a regex::

    name: promise
    criteria: 'success_rate == 100%'
    description: >-
        Test suite from Promise project.
    dependencies:
        installer: '(fuel)|(joid)'
        scenario: ''

In the example above, it means that promise test will be runnable only
with joid or fuel installers on any scenario.

The vims criteria means any installer and exclude onos and odl with
bgpvpn scenarios::

    name: vims
    criteria: 'status == "PASS"'
    description: >-
        This test case deploys an OpenSource vIMS solution from Clearwater
        using the Cloudify orchestrator. It also runs some signaling traffic.
    dependencies:
        installer: ''
        scenario: '(ocl)|(nosdn)|^(os-odl)((?!bgpvpn).)*$'


How to write and check constaint regex?
=======================================

Regex are standard regex. You can have a look at  `[11]`_

You caa also easily test your regex via an online regex checker such as
 `[12]`_.
Put your scenario in the TEST STRING window (e.g. os-odl_l3-ovs-ha), put
your regex in the REGULAR EXPRESSION window, then you can test your rule
.


How to know which test I can run?
=================================

You can use the API `[13]`_. The static declaration is in git `[5]`_

If you are in a Functest docker container (assuming that the
environement has been prepared): just use the new CLI.

You can get the list per Test cases or by Tier::

    # functest testcase list
    healthcheck
    vping_ssh
    vping_userdata
    tempest_smoke_serial
    rally_sanity
    odl
    doctor
    security_scan
    tempest_full_parallel
    rally_full
    vims
    # functest tier list
    - 0. healthcheck:
    ['healthcheck']
    - 1. smoke:
    ['vping_ssh', 'vping_userdata', 'tempest_smoke_serial', 'rally_sanity']
    - 2. sdn_suites:
    ['odl']
    - 3. features:
    ['doctor', 'security_scan']
    - 4. openstack:
    ['tempest_full_parallel', 'rally_full']
    - 5. vnf:
    ['vims']


How to manually start Functest test?
====================================

Assuming that you are connected on the jumhost and that the system is
"Pharos compliant", i.e the technical architecture is compatible with
the one defined in the Pharos project::

    # docker pull opnfv/functest:latest
    # envs="-e INSTALLER_TYPE=fuel -e INSTALLER_IP=10.20.0.2 -e DEPLOY_SCENARIO=os-odl_l2-nofeature-ha -e CI_DEBUG=true"
    # sudo docker run --privileged=true -id ${envs} opnfv/functest:latest /bin/bash


Then you must connect to the docker container and source the
credentials::

    # docker ps (copy the id)
    # docker exec -ti <container_id> bash
    # source $creds


You must first check if the environment is ready::

    # functest env status
    Functest environment ready to run tests.


If not ready, prepare the env by launching::

    # functest env prepare
    Functest environment ready to run tests.

Once the Functest env is ready, you can use the CLI to start tests.

You can run test cases per test case or per tier:
 # functest testcase run <case name> or # functest tier run  <tier name>


e.g::

    # functest testcase run tempest_smoke_serial
    # functest tier run features


If you want to run all the tests you can type::

    # functest testcase run all


If you want to run all the tiers (same at the end that running all the
test cases) you can type::

    # functest tier run all


How to declare my tests in Functest?
====================================

If you want to add new internal test cases, you can submit patch under
the testcases directory of Functest reporsitory.

For feature test integration, the code can be kept into your own
repository. Then the files of the Functest repository you must modify to
integrate Functest are:

 * functest/docker/Dockerfile: get your code in Functest container
 * functest/ci/testcases.yaml: reference your test and its associated constraints
 * functest/ci/exec_test.sh: run your test from CI and CLI


Dockerfile
----------

This file lists the repositories to be cloned in the Functest container.
The repositories can be internal or external::

 RUN git clone https://gerrit.opnfv.org/gerrit/<your project> ${repos_dir}/<your project>

testcases.yaml
--------------

All the test cases that must be run from CI / CLI must be declared in
co/testcases.yaml.
This file is used to get the constraintes related to the test::

    name: <my_super_test_case>
    criteria: <not used yet in Colorado, could be > 'PASS', 'rate > 90%'
    description: >-
        <the description of your super test suite>
    dependencies:
        installer: regex related to installer e.g. 'fuel', '(apex)||(joid)'
        scenario: regex related to the scenario e.g. 'ovs*no-ha'


You must declare your test case in one of the category (tier).

If you are integrating test suites from a feature project, the category
must be features.


exec_test.sh
------------

This file is used to start your test. It is used in CI but also by the
CLI.

You just patch the file in git and add a line::


    "<my_super_test_case>")
        python ${FUNCTEST_REPO_DIR}/testcases/features/mycase.py
    ;;


Note you can use python or bash scripts.


How to select my list of tests for CI?
======================================

Functest can be run automatically from CI, a jenkins job is usually
called after an OPNFV fresh installation.
By default we try to run all the possible tests (see `[14]` called from
Functest jenkins job)::

    cmd="python ${FUNCTEST_REPO_DIR}/ci/run_tests.py -t all ${flags}"


Each case can be configured as daily and/or weekly task.
When executing run_tests.py a check based on the jenkins build tag will
be considered to detect whether it is a daily and/or a weekly test.

in your CI you can customize the list of test you want to run by case or
by tier, just change the line::

    cmd="python ${FUNCTEST_REPO_DIR}/ci/run_tests.py -t <whatever you want> ${flags}"

e.g.::

    cmd="python ${FUNCTEST_REPO_DIR}/ci/run_tests.py -t healthcheck,smoke ${flags}"

This command will run all the test cases of the first 2 tiers, i.e.
healthcheck, vping_ssh, vping_userdata, tempest_smoke_serial and
rally_sanity.


How to push your results into the Test Database
===============================================

The test database is used to collect test results. By default it is
enabled only for CI tests from Production CI pods.

The architecture and associated API is described in previous chapter.
If you want to push your results from CI, you just have to use the API
at the end of your script.

You can also reuse a python function defined in functest_utils.py::

    def push_results_to_db(db_url, case_name, logger, pod_name,version, payload):
      """
      POST results to the Result target DB
      """
      url = db_url + "/results"
      installer = get_installer_type(logger)
      params = {"project_name": "functest", "case_name": case_name,
                "pod_name": pod_name, "installer": installer,
                "version": version, "details": payload}

      headers = {'Content-Type': 'application/json'}
      try:
          r = requests.post(url, data=json.dumps(params), headers=headers)
          if logger:
              logger.debug(r)
          return True
      except Exception, e:
          print "Error [push_results_to_db('%s', '%s', '%s', '%s', '%s')]:" \
              % (db_url, case_name, pod_name, version, payload), e
          return False
