Example Screenshot of visualVM .. image:: images/distribution-s3p-vvm-sample.png Stability Test of Policy Distribution +++++++++++++++++++++++++++++++++++++ Introduction ------------ The 72 hour Stability Test for policy distribution has the goal of introducing a steady flow of transactions initiated from a test client server running JMeter. The policy distribution is configured with a special FileSystemReception plugin to monitor a local directory for newly added csar files to be processed by itself. The input CSAR will be added/removed by the test client(JMeter) and the result will be pulled from the backend(PAP and PolicyAPI) by the test client (JMeter). The test will be performed in an environment where Jmeter will continuously add/remove a test csar into the special directory where policy distribuion is monitoring and will then get the processed results from PAP and PolicyAPI to verify the successful deployment of the policy. The policy will then be undeployed and the test will loop continuously until 72 hours have elapsed. Test Plan Sequence ------------------ The 72h stability test will run the following steps sequentially in a single threaded loop. - **Delete Old CSAR** - Checks if CSAR already exists in the watched directory, if so it deletes it - **Add CSAR** - Adds CSAR to the directory that distribution is watching - **Get Healthcheck** - Ensures Healthcheck is returning 200 OK - **Get Statistics** - Ensures Statistics is returning 200 OK - **CheckPDPGroupQuery** - Checks that PDPGroupQuery contains the deployed policy - **CheckPolicyDeployed** - Checks that the policy is deployed - **Undeploy Policy** - Undeploys the policy - **Delete Policy** - Deletes the Policy for the next loop - **Check PDP Group for Deletion** - Ensures the policy has been removed and does not exist The following steps can be used to configure the parameters of the test plan. - **HTTP Authorization Manager** - used to store user/password authentication details. - **HTTP Header Manager** - used to store headers which will be used for making HTTP requests. - **User Defined Variables** - used to store following user defined parameters. ========== =============================================== **Name** **Description** ========== =============================================== PAP_HOST IP Address or host name of PAP component PAP_PORT Port number of PAP for making REST API calls API_HOST IP Address or host name of API component API_PORT Port number of API for making REST API calls DURATION Duration of Test ========== =============================================== Screenshot of Distribution stability test plan .. image:: images/distribution-s3p-testplan.png Running the Test Plan --------------------- Edit the /tmp folder permissions to allow the testplan to insert the CSAR into the /tmp/policydistribution/distributionmount folder .. code-block:: bash sudo mkdir -p /tmp/policydistribution/distributionmount sudo chmod -R a+trwx /tmp From the apache JMeter folder run the test for 72h, pointing it towards the stability.jmx file inside the testplans folder and specifying a logfile to collect the results .. code-block:: bash ~/jmeter/apache-jmeter-5.1.1/bin/jmeter -n -t ~/distribution/testsuites/stability/src/main/resources/testplans/stability.jmx -Jduration=259200 -l ~/20201016-1715-distr-stability.jtl & Test Results ------------ **Summary** - Stability test plan was triggered for 72 hours. - No errors were reported **Test Statistics** .. csv-table:: Stability Results - Summary Report :file: csv/20201016-1715-distr-stability-summary.csv :header-rows: 1 .. csv-table:: Stability Results - Aggregate Report :file: csv/20201016-1715-distr-stability-aggregate.csv :header-rows: 1 **VisualVM Screenshots** .. image:: images/20201016-1715-distr-stability-20201018T2040-monitor.png .. image:: images/20201016-1715-distr-stability-20201018T2040-threads.png Performance Test of Policy Distribution +++++++++++++++++++++++++++++++++++++++ Introduction ------------ The 4h Performance Test of Policy Distribution 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. It also tests that distribution can handle multiple policy CSARs and that these are deployed within 30 seconds consistently. Setup Details ------------- The performance test is based on the same setup as the distribution stability tests. Test Plan Sequence ------------------ Performance test plan is different from the stability test plan. - Instead of handling one policy csar at a time, multiple csar's are deployed within the watched folder at the exact same time. - We expect all policies from these csar's to be deployed within 30 seconds. - There are also multithreaded tests running towards the healtchcheck and statistics endpoints of the distribution service. Running the Test Plan --------------------- Edit the /tmp folder permissions to allow the Testplan to insert the CSAR into the /tmp/policydistribution/distributionmount folder. .. code-block:: bash sudo mkdir -p /tmp/policydistribution/distributionmount sudo chmod -R a+trwx /tmp From the apache JMeter folder run the test for 4h, pointing it towards the performance.jmx file inside the testplans folder and specifying a logfile to collect the results .. code-block:: bash ~/jmeter/apache-jmeter-5.1.1/bin/jmeter -n -t ~/distribution/testsuites/performance/src/main/resources/testplans/performance.jmx -Jduration=14400 -l ~/20201020-1730-distr-performance.jtl & Test Results ------------ **Summary** - Performance test plan was triggered for 4 hours. - No errors were reported **Test Statistics** .. csv-table:: Performance Results - Summary Report :file: csv/20201020-1730-distr-performance-summary.csv :header-rows: 1 .. csv-table:: Performance Results - Aggregate Report :file: csv/20201020-1730-distr-performance-aggregate.csv :header-rows: 1 **VisualVM Screenshots** .. image:: images/20201020-1730-distr-performance-20201020T2025-monitor.png .. image:: images/20201020-1730-distr-performance-20201020T2025-threads.png
