+
+============
+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 and VNF onboarding project testing.
+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 Danube are:
+
+ * healthcheck
+ * connection_check
+ * api_check
+ * vping_ssh
+ * vping_userdata
+ * odl
+ * snaps_smoke
+ * tempest_smoke_serial
+ * rally_sanity
+ * tempest_full_parallel
+ * rally_full
+ * cloudify_ims
+
+By internal, we mean that this particular test cases have been
+developped and/or integrated by functest contributors and the associated
+code is hosted in the Functest repository.
+An internal case can be fully developped or a simple integration of
+upstream suites (e.g. Tempest/Rally developped in OpenStack are just
+integrated in Functest).
+The structure of this repository is detailed in `[1]`_.
+The main internal test cases are in the opnfv_tests subfolder of the
+repository, the internal test cases are:
+
+ * sdn: odl, onos
+ * openstack: healthcheck, vping_ssh, vping_userdata, tempest_*, rally_*, connection_check, api_check, snaps_smoke
+ * vnf: cloudify_ims
+
+If you want to create a new test case you will have to create a new
+folder under the testcases directory.
+
+Functest external test cases
+============================
+The external test cases are inherited from other OPNFV projects,
+especially the feature projects.
+
+The external test cases are:
+
+ * promise
+ * doctor
+ * onos
+ * bgpvpn
+ * copper
+ * security_scan
+ * sfc-odl
+ * sfc-onos
+ * parser
+ * domino
+ * multisite
+ * opera_ims
+ * orchestra_ims
+
+
+The code to run these test cases may be directly in the repository of
+the project. We have also a **features** sub directory under opnfv_tests
+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 as a docker file, including tools, scripts and a CLI
+to prepare the environement and run tests.
+It simplifies the integration of external test suites 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).
+
+The definition of the tiers has been agreed by the testing working group.
+
+The tiers are:
+ * healthcheck
+ * smoke
+ * features
+ * components
+ * performance
+ * vnf
+ * stress
+
+Functest abstraction classes
+============================
+
+In order to harmonize test integration, 3 abstraction classes have been
+introduced in Danube:
+
+ * testcase_base: base for any test case
+ * feature_base: abstraction for feature project
+ * vnf_base: abstraction for vnf onboarding
+
+The goal is to unify the way to run test from Functest.
+
+feature_base and vnf_base inherit from testcase_base.
+

+ | |
+ | Testcase_base |
+ | |
+ | - init() |
+ | - run() |
+ | - publish_report() |
+ | - check_criteria() |

+ | | | - test_vnf() |
+ | | | - clean() |
+ | | | - execute() |
+ | | | |
+ +--------------------+ +--------------------------+
+
+
+Functest util classes
+=====================
+
+In order to simplify the creation of test cases, Functest develops some
+functions that can be used by any feature or internal test cases.
+Several features are supported such as logger, configuration management and
+Openstack capabilities (snapshot, clean, tacker,..).
+These functions can be found under <repo>/functest/utils and can be described as
+follows:
+
+functest/utils/
+|-- config.py
+|-- constants.py
+|-- env.py
+|-- functest_constants.py
+|-- functest_logger.py
+|-- functest_utils.py
+|-- openstack_clean.py
+|-- openstack_snapshot.py
+|-- openstack_tacker.py
+`-- openstack_utils.py
+
+Note that for Openstack, keystone v3 is now deployed by default by compass,
+fuel and joid in Danube. All installers still support keysone v2 (deprecated in
+next version).
+
+Test collection framework
+=========================
+
+The OPNFV testing group created a test collection database to collect
+the test results from CI:
+
+
+ http://testresults.opnfv.org/test/swagger/spec.html
+
+ Authentication: opnfv/api@opnfv
+
+Any test project running on any lab integrated in CI can push the
+results to this database.
+This database can be used to see the evolution of the tests and compare
+the results versus the installers, the scenarios or the labs.
+
+
+Overall Architecture
+--------------------
+The Test result management can be summarized as follows::
+
+ +-------------+ +-------------+ +-------------+
+ | | | | | |
+ | Test | | Test | | Test |
+ | Project #1 | | Project #2 | | Project #N |

+
+Test API description
+--------------------
+The Test API is used to declare pods, projects, test cases and test
+results. Pods are the pods used to run the tests.
+The results pushed in the database are related to pods, projects and
+cases. If you try to push results of test done on non referenced pod,
+the API will return an error message.
+
+An additional method dashboard has been added to post-process
+the raw results in release Brahmaputra (deprecated in Colorado).
+
+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": {
+ "current": 0,
+ "histories": []
+ }
+ }
+
+The API can described as follows. For detailed information, please go to

+
+
+The code of the API is hosted in the releng repository `[6]`_.
+The static documentation of the API can be found at `[17]`_.
+The test API has been dockerized and may be installed locally in your
+lab. See `[15]`_ for details.
+
+The deployment of the test API has been automated.
+A jenkins job manages:
+ * the unit tests of the test api
+ * the creation of a new docker file
+ * the deployment of the new test api
+ * the archive of the old test api
+ * the backup of the Mongo DB
+
+Test API Authorization
+~~~~~~~~~~~~~~~~~~~~~~
+
+PUT/DELETE/POST operations of the testapi now require token based authorization. The token needs
+to be added in the request using a header 'X-Auth-Token' for access to the database.
+
+e.g::
+ headers['X-Auth-Token']
+
+The value of the header i.e the token can be accessed in the jenkins environment variable
+*TestApiToken*. The token value is added as a masked password.
+
+.. code-block:: python
+
+ headers['X-Auth-Token'] = os.environ.get('TestApiToken')
+
+The above example is in Python. Token based authentication has been added so that only ci pods
+jenkins job can have access to the database.
+
+Please note that currently token authorization is implemented but is not yet enabled.
+
+ Automatic reporting
+ ===================
+
+ 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]`_.
+
+ The results are collected from the centralized database every day and,
+ per scenario. A score is calculated based on the results from the last
+ 10 days. This score is the addition of single test scores. Each test
+ case has a success criteria reflected in the criteria field from the
+ results.
+
+ Considering an instance of a scenario os-odl_l2-nofeature-ha, the
+ scoring is the addition of the scores of all the runnable tests from the
+ categories (tiers healthcheck, smoke and features)
+ corresponding to this scenario.
+
+
+ +---------------------+---------+---------+---------+---------+
+ | Test | Apex | Compass | Fuel | Joid |
+ +=====================+=========+=========+=========+=========+
+ | vPing_ssh | X | X | X | X |
+ +---------------------+---------+---------+---------+---------+
+ | vPing_userdata | X | X | X | X |

+ +---------------------+---------+---------+---------+---------+
+
+ All the testcases listed in the table are runnable on
+ os-odl_l2-nofeature scenarios.
+ If no result is available or if all the results are failed, the test
+ case get 0 point.
+ If it was succesfull at least once but not 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. The success criteria are not always easy to define and may
+ require specific hardware configuration. These results however provide
+ a good level of trust on the scenario.
+
+ 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 successful scenarios is no more run (because considered as
+ stable) and then the number of iterations (4 needed) would not be
+ sufficient to get the green status.
+
+ Please note that other test cases (e.g. sfc_odl, bgpvpn) need also
+ ODL configuration addons and as a consequence specific scenario.
+ There are not considered as runnable on the generic odl_l2 scenario.
+
+Dashboard
+=========
+
+Dashboard is used to provide a consistant view of the results collected
+in CI.
+The results showed on the dashboard are post processed from the Database,
+which only contains raw results.
+
+In Brahmaputra, we created a basic dashboard.
+Since Colorado, it was decided to adopt ELK framework. Mongo DB results
+are extracted to feed Elasticsearch database (`[7]`_).
+
+A script was developed to build elasticsearch data set. This
+script can be found in `[16]`_.
+
+For next versions, it was decided to integrated bitergia dashboard.
+Bitergia already provides a dashboard for code and infrastructure.
+A new Test tab will be added. The dataset will be built by consuming
+the test API.
+
+
+=======
+How TOs
+=======
+
+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 in the
+title 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
+FAIL. 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 repository)
+
+
+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 can 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 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 tests?
+=====================================
+
+Assuming that you are connected on the jumphost 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 repository.
+
+For feature test integration, the code can be kept into your own
+repository. The Functest files to be modified are:
+
+ * functest/docker/Dockerfile: get your code in Functest container
+ * functest/ci/testcases.yaml: reference your test and its associated constraints
+
+
+Dockerfile
+----------
+
+This file lists the repositories (internal or external) to be cloned in
+the Functest container. You can also add external packages::
+
+ 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
+ci/testcases.yaml.
+
+This file is used to get the constraints 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 default
+category is **features**.
+
+
+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.
+Weekly tasks are used for long duration or experimental tests.
+Daily tasks correspond to the minimum set of test suites to validate a scenario.
+
+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, connection_check, api_check, vping_ssh, vping_userdata,
+snaps_somke, 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 call 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
