Resiliency tests
----------------
The goal of the resiliency testing was to evaluate the capability of the
-Honolulu solution to survive a stop or restart of a Kubernetes control or
-worker node.
-
-Controller node resiliency
-~~~~~~~~~~~~~~~~~~~~~~~~~~
-
-By default the ONAP solution is installed with 3 controllers for high
-availability. The test for controller resiliency can be described as follows:
-
-- Run tests: check that they are PASS
-- Stop a controller node: check that the node appears in NotReady state
-- Run tests: check that they are PASS
-
-2 tests were performed on the weekly honolulu lab. No problem was observed on
-controller shutdown, tests were still PASS with a stoped controller node.
-
-More details can be found in <https://jira.onap.org/browse/TEST-309>.
-
-Worker node resiliency
-~~~~~~~~~~~~~~~~~~~~~~
-
-In community weekly lab, the ONAP pods are distributed on 12 workers. The goal
-of the test was to evaluate the behavior of the pod on a worker restart
-(disaster scenario assuming that the node was moved accidentally from Ready to
-NotReady state).
-The original conditions of such tests may be different as the Kubernetes
-scheduler does not distribute the pods on the same worker from an installation
-to another.
-
-The test procedure can be described as follows:
-
-- Run tests: check that they are PASS (Healthcheck and basic_vm used)
-- Check that all the workers are in ready state

Stability tests

- SDC stability test

-~~~~~~~~~~~~~~~~~~~~~
-
-This test consists on running the test basic_vm continuously during 72h.
-
-We observe the cluster metrics as well as the evolution of the test duration.
+.. important::
+ The onboarding duration increases linearly with the number of on-boarded
+ models, which is already reported and may be due to the fact that models
+ cannot be deleted. In fact the test client has to retrieve the list of

+ However 1085 on-boarded models is already a vry high figure regarding the
+ possible ONAP usage.
+ Moreover the mean duration time is much lower in Istanbul.

+
+The results are good with a success rate above 95%. After 24h more than 1300
+VNF have been created and deleted.
+
+As for SDC, we can observe a linear increase of the test duration. This issue
+has been reported since Guilin. For SDC as it is not possible to delete the
+models, it is possible to imagine that the duration increases due to the fact
+that the database of models continuously increases. Therefore the client has
+to retrieve an always bigger list of models.
+But for the instantiations, it is not the case as the references
+(module, VNF, service) are cleaned at the end of each test and all the tests
+use the same model. Then the duration of an instantiation test should be
+almost constant, which is not the case. Further investigations are needed.
