Policy API S3P Tests
####################
72 Hours Stability Test of Policy API
+++++++++++++++++++++++++++++++++++++
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 in a multi-threaded fashion to
simulate multiple clients' behaviours.
All the transaction flows are initiated from a test client server running JMeter for the duration of 72 hours.
Setup Details
-------------
The stability test was performed on a default ONAP OOM installation in the Intel Wind River 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:
.. code-block:: bash
nohup ./apache-jmeter-5.4.1/bin/jmeter.sh -n -t policy_api_stability.jmx -l stabilityTestResultsPolicyApi.jtl
The test was run in the background via “nohup”, 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'
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.

Test Results
------------
**Summary**
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.

**JMeter Results**
The following graphs show the response time distributions. The "Get Policy Types" API calls are the most expensive calls that
average a 7 seconds plus response time.

**Memory and CPU usage**
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.

Performance Test of Policy API
++++++++++++++++++++++++++++++
Introduction
------------
Performance test of policy-api has the goal of testing the min/avg/max processing time and rest call throughput for all the requests when the number of requests are large enough to saturate the resource and find the bottleneck.
Setup Details
-------------
The performance test was performed on a default ONAP OOM installation in the Intel Wind River 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-5.4.1/bin/jmeter.sh -n -t policy_api_performance.jmx -l performanceTestResultsPolicyApi.jtl
The test was run in the background via “nohup”, 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' 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*.
