Stability Test of PAP
+++++++++++++++++++++
---------
The 72 hours stability test ran the following steps sequentially in a single threaded loop.
-- **Create Policy defaultDomain** - creates an operational policy using policy/api component
-- **Create Policy sampleDomain** - creates an operational policy using policy/api component
+Setup Phase (steps running only once)
+"""""""""""""""""""""""""""""""""""""
+
+- **Create Policy for defaultGroup** - creates an operational policy using policy/api component
+- **Create NodeTemplate metadata for sampleGroup policy** - creates a node template containing metadata using policy/api component
+- **Create Policy for sampleGroup** - creates an operational policy that refers to the metadata created above using policy/api component
+- **Change defaultGroup state to ACTIVE** - changes the state of defaultGroup PdpGroup to ACTIVE
+- **Create/Update PDP Group** - creates a new PDPGroup named sampleGroup.
+ A second instance of the PDP that is already spun up gets registered to this new group
+- **Check PdpGroup Query** - makes a PdpGroup query request and verifies that both PdpGroups are in ACTIVE state.

Test Results
------------
**Summary**
-Stability test plan was triggered for 72 hours.
-
-.. Note::
+Stability test plan was triggered for 72 hours. There were no failures during the 72 hours test.
- .. container:: paragraph
-
- As part of the OOM deployment, another APEX-PDP pod is spun up with the pdpGroup name specified as 'sampleGroup'.
- After creating the new group called 'sampleGroup' as part of the test, a time delay of 2 minutes is added,
- so that the pdp is registered to the newly created group.
- This has resulted in a spike in the Average time taken per request. But, this is required to make proper assertions,
- and also for the consolidated health check.

- There were some failures during the 72 hour stability tests. These tests were caused by the apex-pdp pods restarting
- intermitently due to limited resources in our testing environment. The second apex instance was configured as a
- replica of the apex-pdp pod and therefore, when it restarted, registered to the "defaultGroup" as the configuration
- was taken from the original apex-pdp pod. This meant a manual change whenever the pods restarted to make apex-pdp-"2"
- register with the "sampleGroup".
- When both pods were running as expected, no errors relating to the pap functionality were observed. These errors are
- strictly caused by the environment setup and not by pap.
+ There were 0.15% failures during the 72 hours test, due to the timing between the update of the metric "undeploySuccessCount" and the Undeploy itself.
+ We suggest for the next test to increase the timeout timing up to 130s between "Undeploy policy in defaultGroup" and "PAP Metrics after deployments"

**Memory and CPU usage**
-The memory and CPU usage can be monitored by running "top" command on the PAP pod. A snapshot is taken before and after test execution to monitor the changes in resource utilization.

Performance Test of PAP
++++++++++++++++++++++++
Performance test plan is the same as the stability test plan above except for the few differences listed below.
-- Increase the number of threads up to 5 (simulating 5 users' behaviours at the same time).
+- Increase the number of threads up to 10 (simulating 10 users' behaviours at the same time).
- Reduce the test time to 2 hours.
-- Usage of counters to create different groups by the 'Create/Update PDP Group' test case.
-- Removed the delay to wait for the new PDP to be registered. Also removed the corresponding assertions where the Pdp instance registration to the newly created group is validated.
+- Usage of counters (simulating each user) to create different pdpGroups, update their state and later delete them.
+- Removed the tests to deploy policies to newly created groups as this will need a larger setup with multiple pdps registered to each group, which will also slow down the performance test with the time needed for registration process etc.
+- Usage of counters (simulating each user) to create different drools policies and deploy them to defaultGroup.
+ In the test, a thread count of 10 is used resulting in 10 different drools policies getting deployed and undeployed continuously for 2 hours.
+ Other standard operations like checking the deployment status of policies, checking the metrics, health etc remains.
