Introduction
------------
-The 72 hour stability test of policy API has the goal of verifying the stability of running policy design API REST service by
-ingesting a steady flow of transactions of policy design API calls in a multi-thread fashion to simulate multiple clients' behaviors.
-All the transaction flows are initiated from a test client server running JMeter for the duration of 72+ hours.

Setup Details
-------------
-The stability test is performed on VMs running in Intel Wind River Lab environment.
-There are 2 seperate VMs. One for running API while the other running JMeter & other necessary components, e.g. MariaDB, to simulate steady flow of transactions.
-For simplicity, let's assume:
-
-VM1 will be running JMeter, MariaDB.
-VM2 will be running API REST service and visualVM.

-Run Test
---------
-
-**Local Machine**
-
-Connect to lab VPN
-
-.. code-block:: bash
-
- $ sudo openvpn --config <path to lab ovpn key file>
-
-SSH into JMeter VM (VM1)
-
-.. code-block:: bash

-
-Run JMeter test in background for 72+ hours
+The stability test was performed on a default ONAP OOM installation in the Nordix Lab environment.
+JMeter was installed on a separate VM to inject the traffic defined in the
+`API stability script
+<https://git.onap.org/policy/api/tree/testsuites/stability/src/main/resources/testplans/policy_api_stability.jmx>`_
+with the following command:

- $ mkdir s3p
- $ nohup ./jMeter/apache-jmeter-5.2.1/bin/jmeter.sh -n -t ~/api/testsuites/stability/src/main/resources/testplans/policy_api_stability.jmx &
+ nohup apache-jmeter-5.5/bin/jmeter -n -t policy_api_stability.jmx -l stabilityTestResultsPolicyApi.jtl &
-(Optional) Monitor JMeter test that is running in background (anytime after re-logging into JMeter VM - VM1)
-
-.. code-block:: bash
-
- $ tail -f s3p/stability.log nohup.out
+The test was run in the background via “nohup” and “&”, to prevent it from being interrupted.
Test Plan
---------
The 72+ hours stability test will be running the following steps sequentially
in multi-threaded loops. Thread number is set to 5 to simulate 5 API clients'
-behaviors (they can be calling the same policy CRUD API simultaneously).
+behaviours (they can be calling the same policy CRUD API simultaneously).
Each thread creates a different version of the policy types and policies to not
interfere with one another while operating simultaneously. The point version
of each entity is set to the running thread number.

+No errors were found during the 72 hours of the Policy API stability run.
+The load was performed against a non-tweaked ONAP OOM installation.

+**Memory and CPU usage**
-PFPP ONAP Windriver lab
+The memory and CPU usage can be monitored by running "top" command in the policy-api pod.
+A snapshot is taken before and after test execution to monitor the changes in resource utilization.
-**Summary**
+Memory and CPU usage before test execution:
-Policy API stability test plan was triggered and running for 72+ hours without
-any real errors occurring. The single failure was on teardown and was due to
-simultaneous test plans running concurrently on the lab system.
+.. image:: api-s3p-results/api_top_before_72h.png
-Compared to El-Alto, 10x the number of API calls were made in the 72 hour run.
-However, the latency increased (most likely due to the synchronization added
-from
-`POLICY-2533 <https://jira.onap.org/browse/POLICY-2533>`_.
-This will be addressed in the next release.

Performance Test of Policy API
Setup Details
-------------
-The performance test is performed on OOM-based deployment of ONAP Policy framework components in Intel Wind River Lab environment.
-In addition, we use another VM with JMeter installed to generate the transactions.
-The JMeter VM will be sending large number of REST requests to the policy-api component and collecting the statistics.
-Policy-api component already knows how to communicate with MariaDB component if OOM-based deployment is working correctly.
+The performance test was performed on a default ONAP OOM installation in the Nordix Lab environment.
+JMeter was installed on a separate VM to inject the traffic defined in the
+`API performance script
+<https://git.onap.org/policy/api/tree/testsuites/performance/src/main/resources/testplans/policy_api_performance.jmx>`_
+with the following command:
+
+.. code-block:: bash
+
+ nohup apache-jmeter-5.5/bin/jmeter -n -t policy_api_performance.jmx -l performanceTestResultsPolicyApi.jtl &
+
+The test was run in the background via “nohup” and “&”, to prevent it from being interrupted.
Test Plan
---------
Performance test plan is the same as stability test plan above.
-Only differences are, in performance test, we increase the number of threads up to 20 (simulating 20 users' behaviors at the same time) whereas reducing the test time down to 1 hour.
+Only differences are, in performance test, we increase the number of threads up to 20 (simulating 20 users' behaviours at the same time) whereas reducing the test time down to 2.5 hours.
Run Test
--------
Running/Triggering performance test will be the same as stability test. That is, launch JMeter pointing to corresponding *.jmx* test plan. The *API_HOST* and *API_PORT* are already set up in *.jmx*.

Test Results
------------
-Test results are shown as below. Overall, the test was running smoothly and successfully. We do see some minor failed transactions, especially in POST calls which intend to write into DB simultaneously in a multi-threaded fashion . All GET calls (reading from DB) were succeeded.
