+Microversion Testing With Tempest
+=================================
 
-Tempest provides stable interfaces to test API Microversion.
-For Details, see: `API Microversion testing Framework`_
-This document explains how to implement Microversion tests using those
-interfaces.
+Many OpenStack Services provide their APIs with `microversion`_
+support and want to test them in Tempest.
 
-.. _API Microversion testing Framework: http://docs.openstack.org/developer/tempest/library/api_microversion_testing.html
+.. _microversion: http://specs.openstack.org/openstack/api-wg/guidelines/microversion_specification.html
+
+This document covers how to test microversions for each project and
+whether tests should live in Tempest or on project side.
+
+Tempest Scope For Microversion Testing
+""""""""""""""""""""""""""""""""""""""
+APIs microversions for any OpenStack service grow rapidly and
+testing each and every microversion in Tempest is not feasible and
+efficient way.
+Also not every API microversion changes the complete system behavior
+and many of them only change the API or DB layer to accept and return more
+data on API.
+
+Tempest is an integration test suite, but not all API microversion testing fall under this category.
+As a result, Tempest mainly covers integration test cases for microversions, Other testing coverage
+for microversion should be hosted on project side as functional tests or via Tempest plugin as per
+project guidelines.
+
+.. note:: Integration tests are those tests which involve more than one service to
+     verify the expected behavior by single or combination of API requests.
+     If a test is just to verify the API behavior as success and failure cases
+     or verify its expected response object, then it does not fall under integration
+     tests.
+
+Tempest will cover only integration testing of applicable microversions with
+below exceptions:
+
+  #. Test covers a feature which is important for interoperability. This covers tests requirement
+     from Defcore.
+  #. Test needed to fill Schema gaps.
+     Tempest validates API responses with defined JSON schema. API responses can be different on
+     each microversion and the JSON schemas need to be defined separately for the microversion.
+     While implementing new integration tests for a specific microversion, there
+     may be a gap in the JSON schemas (caused by previous microversions) implemented
+     in Tempest.
+     Filling that gap while implementing the new integration test cases is not efficient due to
+     many reasons:
+
+     * Hard to review
+     * Sync between multiple integration tests patches which try to fill the same schema gap at same
+       time
+     * Might delay the microversion change on project side where project team wants Tempest
+       tests to verify the results.
+
+     Tempest will allow to fill the schema gaps at the end of each cycle, or more
+     often if required.
+     Schema gap can be filled with testing those with a minimal set of tests. Those
+     tests might not be integration tests and might be already covered on project
+     side also.
+     This exception is needed because:
+
+     * Allow to create microversion response schema in Tempest at the same time that projects are
+       implementing their API microversions. This will make implementation easier for adding
+       required tests before a new microversion change can be merged in the corresponding project
+       and hence accelerate the development of microversions.
+     * New schema must be verified by at least one test case which exercises such schema.
+
+     For example:
+        If any projects implemented 4 API microversion say- v2.3, v2.4, v2.5, v2.6
+        Assume microversion v2.3, v2.4, v2.6 change the API Response which means Tempest
+        needs to add JSON schema for v2.3, v2.4, v2.6.
+        In that case if only 1 or 2 tests can verify all new schemas then we do not need
+        separate tests for each new schemas. In worst case, we have to add 3 separate tests.
+  #. Test covers service behavior at large scale with involvement of more deep layer like hypervisor
+     etc not just API/DB layer. This type of tests will be added case by case basis and
+     with project team consultation about why it cannot be covered on project side and worth to test
+     in Tempest.
+
+Project Scope For Microversion Testing
+""""""""""""""""""""""""""""""""""""""
+All microversions testing which are not covered under Tempest as per above section, should be
+tested on project side as functional tests or as Tempest plugin as per project decision.

+
+Interacting with Credentials and Clients
+========================================
+
+Once you have your basic TestCase setup you'll want to start writing tests. To
+do that you need to interact with an OpenStack deployment. This section will
+cover how credentials and clients are used inside of Tempest tests.
+
+
+Manager Objects
+---------------
+
+The primary interface with which you interact with both credentials and
+API clients is the client manager object. These objects are created
+automatically by the base test class as part of credential setup (for more
+details see the previous :ref:`credentials` section). Each manager object is
+initialized with a set of credentials and has each client object already setup
+to use that set of credentials for making all the API requests. Each client is
+accessible as a top level attribute on the manager object. So to start making
+API requests you just access the client's method for making that call and the
+credentials are already setup for you. For example if you wanted to make an API
+call to create a server in Nova::
+
+  from tempest import test
+
+
+  class TestExampleCase(test.BaseTestCase):
+    def test_example_create_server(self):
+      self.os.servers_client.create_server(...)
+
+is all you need to do. As described previously, in the above example the ``self.os``
+is created automatically because the base test class sets the ``credentials``
+attribute to allocate a primary credential set and initializes the client
+manager as ``self.os``. This same access pattern can be used for all of the
+clients in Tempest.
+
+Credentials Objects
+-------------------
+
+In certain cases you need direct access to the credentials (the most common
+use case would be an API request that takes a user or project id in the request
+body). If you're in a situation where you need to access this you'll need to
+access the ``credentials`` object which is allocated from the configured
+credential provider in the base test class. This is accessible from the manager
+object via the manager's ``credentials`` attribute. For example::
+
+  from tempest import test
+
+
+  class TestExampleCase(test.BaseTestCase):
+    def test_example_create_server(self):
+      credentials = self.os.credentials
+
+The credentials object provides access to all of the credential information you
+would need to make API requests. For example, building off the previous
+example::
+
+  from tempest import test
+
+
+  class TestExampleCase(test.BaseTestCase):
+    def test_example_create_server(self):
+      credentials = self.os.credentials
+      username = credentials.username
+      user_id = credentials.user_id
+      password = credentials.password
+      tenant_id = credentials.tenant_id
