+How to exclude Tempest case from default Tempest smoke suite?
+=============================================================
+
+Tempest default smoke suite deals with 165 test cases.
+Since Colorado the success criteria is 100%, i.e. if 1 test is failed the
+success criteria is not matched for the scenario.
+
+It is necessary to exclude some test cases that are expected to fail due to
+known upstream bugs (see release notes).
+
+A file has been created for such operation: https://git.opnfv.org/cgit/functest/tree/functest/opnfv_tests/openstack/tempest/custom_tests/blacklist.txt.
+
+It can be described as follows::
+
+    -
+        scenarios:
+            - os-odl_l2-bgpvpn-ha
+            - os-odl_l2-bgpvpn-noha
+        installers:
+            - fuel
+            - apex
+        tests:
+            - tempest.api.compute.servers.test_create_server.ServersTestJSON.test_list_servers
+            - tempest.api.compute.servers.test_create_server.ServersTestJSON.test_verify_server_details
+            - tempest.api.compute.servers.test_create_server.ServersTestManualDisk.test_list_servers
+            - tempest.api.compute.servers.test_create_server.ServersTestManualDisk.test_verify_server_details

+            - tempest.scenario.test_volume_boot_pattern.TestVolumeBootPatternV2.test_volume_boot_pattern
+
+Please note that each exclusion must be justified. the goal is not to exclude
+test cases because they do not pass. Several scenarios reached the 100% criteria.
+So it is expected in the patch submited to exclude the cases to indicate the
+reasons of the exclusion.
+
+
+How do I know the Functest status of a scenario?
+================================================
+
+A Functest automatic reporting page is generated daily.
+This page is dynamically created through a cron job and is based on the results
+stored in the Test DB.
+You can access this reporting page: http://testresults.opnfv.org/reporting

+|                | Those come from Feature projects and need a bit of support  |
+|                | for integration                                             |

+| VNF            | Test cases related to deploy an open source VNF including   |
+|                | an orchestrator                                             |
++----------------+-------------------------------------------------------------+
+
+The main ambiguity could be between features and VNF.
+In fact sometimes you have to spawn VMs to demonstrate the capabilities of the
+feature you introduced.
+We recommend to declare your test in the feature category.
+
+VNF category is really dedicated to test including:
+
+ * creation of resources
+ * deployement of an orchestrator/VNFM
+ * deployment of the VNF
+ * test of the VNFM
+ * free resources
+
+The goal is not to study a particular feature on the infrastructure but to have
+a whole end to end test of a VNF automatically deployed in CI.
+Moreover VNF are run in weekly jobs (one a week), feature tests are in daily
+jobs and use to get a scenario score.
+
+Where are the logs?
+===================
+
+Functest deals with internal and external testcases. Each testcase can generate
+logs.
+
+Since Colorado we introduce the possibility to push the logs to the artifact.
+A new script (https://git.opnfv.org/releng/tree/utils/push-test-logs.sh) has
+been created for CI.
+
+When called, and assuming that the POD is authorized to push the logs to
+artifacts, the script will push all the results or logs locally stored under
+/home/opnfv/functest/results/.
+
+If the POD is not connected to CI, logs are not pushed.
+But in both cases, logs are stored in /home/opnfv/functest/results in the
+container.
+Projects are encouraged to push their logs here.
+
+Since Colorado it is also easy for feature project to integrate this feature by
+adding the log file as output_file parameter when calling execute_command from
+functest_utils library
+
+  ret_val = functest_utils.execute_command(cmd, output_file=log_file)
+
+
+How does Functest deal with VNF onboarding?
+===========================================
+
+VNF onboarding has been introduced in Brahmaputra through the automation of a
+clearwater vIMS deployed thanks to cloudify orchestrator.
+
+This automation has been described at OpenStack summit Barcelona:
+https://youtu.be/Jr4nG74glmY
+
+The goal of Functest consists in testing OPNFV from a functional perspective:
+the NFVI and/or the features developed in OPNFV. Feature test suites are
+provided by the feature project. Functest just simplifies the integration of
+the suite into the CI and gives a consolidated view of the tests per scenario.
+
+Functest does not develop VNFs.
+
+Functest does not test any MANO stack.
+
+OPNFV projects dealing with VNF onboarding
+------------------------------------------
+
+Testing VNF is not the main goal however it gives interesting and realistic
+feedback on OPNFV as a Telco cloud.
+
+Onboarding VNF also allows to test a full stack: orchestrator + VNF.
+
+Functest is VNF and MANO stack agnostic.
+
+An internship has been initiated to reference the Open Source VNF: Intern
+Project Open Source VNF catalog
+
+New projects dealing with orchestrators or VNFs are candidate for Danube.
+
+The 2 projects dealing with orchestration are:
+
+ * orchestra (Openbaton)
+ * opera (Open-O)
+
+The Models project address various goals for promoting availability and
+convergence of information and/or data models related to NFV service/VNF
+management, as being defined in standards (SDOs) and as developed in open
+source projects.
+
+Functest VNF onboarding
+-----------------------
+
+In order to simplify VNF onboarding a new abstraction class has been developed
+in Functest.
+
+This class is based on vnf_base and can be described as follow:
+
+ +------------+             +--------------+
+ | test_base  |------------>|   vnf_base   |
+ +------------+             +--------------+
+                              |_ prepare
+                                  |_ deploy_orchestrator (optional)
+                                      |_ deploy_vnf
+                                        |_ test_vnf
+                                          |_ clean
+
+
+Several methods are declared in vnf_base:
+
+ * prepare
+ * deploy_orchestrator
+ * deploy_vnf
+ * test_vnf
+ * clean
+
+deploy_vnf and test_vnf are mandatory.
+
+prepare will create a user and a project.
+
+How to declare your orchestrator/VNF?
+-------------------------------------
+1) test declaration
+
+You must declare your testcase in the file <Functest repo>/functest/ci/testcases.yaml
+
+2) configuration
+
+You can precise some configuration parameters in config_functest.yaml
+
+3) implement your test
+
+Create your own VnfOnboarding file
+
+you must create your entry point through a python clase as referenced in the
+configuration file
+
+e.g. aaa => creation of the file <Functest repo>/functest/opnfv_tests/vnf/aaa/aaa.py
+
+the class shall inherit vnf_base.
+You must implement the methods deploy_vnf() and test_vnf() and may implement
+deploy_orchestrator()
+
+you can call the code from your repo (but need to add the repo in Functest if
+it is not the case)
+
+4) success criteria
+
+So far we considered the test as PASS if vnf_deploy and test_vnf is PASS
+(see example in aaa).
