+Code quality
+------------
+
+It is recommended to control the quality of the code of the testing projects,
+and more precisely to implement some verifications before any merge:
+  * pep8
+  * pylint
+  * unit tests (python 2.7)
+  * unit tests (python 3.5)
+
+
+The code of the test project must be covered by unit tests. The coverage
+shall be reasonable and not decrease when adding new features to the framework.
+The use of tox is recommended.
+It is possible to implement strict rules (no decrease of pylint score, unit
+test coverages) on critical python classes.

-TestAPI description
-===================
-The TestAPI is used to declare pods, projects, test cases and test
-results. Pods are the sets of bare metal or virtual servers and networking
-equipments used to run the tests.
-
-The results pushed in the database are related to pods, projects and test 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, 5 objects are created:
-
-  * Pods
-  * Projects
-  * Testcases
-  * Results
-  * Scenarios
-
-The code of the API is hosted in the releng repository `[6]`_.
-The static documentation of the API can be found at `[7]`_.
-The TestAPI has been dockerized and may be installed locally in your
-lab. See `[15]`_ for details.
-
-The deployment of the TestAPI has been automated.
-A jenkins job manages:
-
-  * the unit tests of the TestAPI
-  * the creation of a new docker file
-  * the deployment of the new TestAPI
-  * the archive of the old TestAPI
-  * the backup of the Mongo DB
-
-TestAPI 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.

-Reporting
-=========
-
-An automatic reporting page has been created in order to provide a
-consistent 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.
-
-Dashboard
-=========
-
-Dashboard is used to provide a consistent view of the results collected in CI.
-The results showed on the dashboard are post processed from the Database,
-which only contains raw results.
-
-It can be used in addition of the reporting page (high level view) to allow
-the creation of specific graphs according to what the test owner wants to show.
-
-In Brahmaputra, a basic home made dashboard was created in Functest.
-In Colorado, Yardstick adopted Grafana (time based graphs) and ELK (complex
-graphs).
-Since Danube, the testing community decided to adopt ELK framework and to rely
-on bitergia. It was not implemented for Danube but it is planned for Euphrates.
-
-Bitergia already provides a dashboard for code and infrastructure.
-A new Test tab will be added. The dataset will be built by consuming
-the TestAPI.
-
-See `[3]`_ for details.

 How TOs
 =======
 
 Where can I find information on the different test projects?
 ===========================================================
+On http://docs.opnfv.org! A section is dedicated to the testing projects. You
+will find the overview of the ecosystem and the links to the project documents.
+
+Another source is the testing wiki on https://wiki.opnfv.org/display/testing
+
+You may also contact the testing group on the IRC channel #opnfv-testperf or by
+mail at test-wg AT lists.opnfv.org (testing group) or opnfv-tech-discuss AT
+lists.opnfv.org (generic technical discussions).
 
 
 How can I contribute to a test project?
 =======================================
+As any project, the best solution is to contact the project. The project
+members with their email address can be found under
+https://git.opnfv.org/<project>/tree/INFO
+
+You may also send a mail to the testing mailing list or use the IRC channel
+#opnfv-testperf
 
 
 Where can I find hardware resources?
 ====================================
+You should discuss this topic with the project you are working with. If you need
+access to an OPNFV community POD, it is possible to contact the infrastructure
+group. Depending on your needs (scenario/installer/tooling), it should be
+possible to find free time slots on one OPNFV community POD from the Pharos
+federation. Create a JIRA ticket to describe your needs on
+https://jira.opnfv.org/projects/INFRA.
+You must already be an OPNFV contributor. See
+https://wiki.opnfv.org/display/DEV/Developer+Getting+Started.
+
+Please note that lots of projects have their own "how to contribute" or
+"get started" page on the OPNFV wiki.
 
 
 How do I integrate my tests in CI?
 ==================================
-
+It shall be discussed directly with the project you are working with. It is
+done through jenkins jobs calling testing project files but the way to onboard
+cases differ from one project to another.
 
 How to declare my tests in the test Database?
 =============================================
+If you have access to the test API swagger (access granted to contributors), you
+may use the swagger interface of the test API to declare your project.
+The URL is http://testresults.opnfv.org/test/swagger/spec.html.
+

+Click on *Spec*, the list of available methods must be displayed.

+   :align: center
+   :alt: Testing Group Test API swagger
+
+For the declaration of a new project use the POST /api/v1/projects method.
+For the declaration of new test cases in an existing project, use the POST
+ /api/v1/projects/{project_name}/cases method
