+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.

+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).

+ Automatic reporting
+ ===================
+
+ An automatic reporting page has been created in order to provide a

+ 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.
