Manual testing with Postman

Build cps-and-ncmp docker image for version to be tested. Run maven from cps repo directory:
Code Block
language bash
mvn clean install -Pcps-ncmp-docker
Edit docker-compose/docker-compose.yml to filter notifications: set NOTIFICATION_DATASPACE_FILTER_PATTERNS to NON-EXISTING-DATASPACE
Code Block
language yml
cps-and-ncmp: environment: notification.enabled: 'true' NOTIFICATION_DATASPACE_FILTER_PATTERNS: 'NON-EXISTING-DATASPACE'

Start docker-compose with DMI plugin stub and monitoring enabled:

Code Block

language	bash

docker-compose -f docker-compose/docker-compose.yml --profile dmi-stub --profile monitoring up

Wait for CPS to start. Console output will show:

Code Block

language	text

cps-and-ncmp            | {"logTimeStamp":"2023-03-24T16:20:36.705Z","logLevel":"INFO","principalId":"cpsuser","serviceName":"cps-application","message":"Started Application in 47.336 seconds (JVM running for 48.444)","processId":"1","threadName":"main","class":"org.onap.cps.Application"}

Test using Postman

Start Postman, and import the NCMP de-register performance postman collection. (This step only needs to be done once.)
Click the new collection, and open the "Variables" tab
Change the current value of TOTAL_CMHANDLES to the desired value, e.g. 10000, and click the "Save" button. This is the number of CM handles that will be registered (and later de-registered).
Select "Register CM handles", and click "Send". (The Postman collection will use a script to automatically create the request body with 10000 CM handles.)

Wait until all CM handles are in READY state. This can take a while, especially with lot of handles.
We can check how many handles are ready by running a query on the database. Here are instructions using the Postgres command line interface (psql), but you may alternatively use the Postgres GUI client.

Open a new terminal window, and install postgres-client if needed:

Code Block

$ sudo apt install postgresql-client
Reading package lists... Done
Building dependency tree... Done
Reading state information... Done
postgresql-client is already the newest version (14+238).
0 upgraded, 0 newly installed, 0 to remove and 4 not upgraded.

Run psql command to connect to the database (default password is cps):

Code Block
$ psql -h localhost -p 5432 cpsdb cps Password for user cps: psql (14.6 (Ubuntu 14.6-0ubuntu0.22.04.1), server 14.1) Type "help" for help. cpsdb=#

Run the following query to count the number of handles in the READY state. You will need to repeat this command, until all are ready (e.g. 10000).

Code Block

cpsdb=# SELECT count(*) FROM public.fragment where attributes @> '{"cm-handle-state": "READY"}';
 count 
-------
  3540
(1 row)

cpsdb=# SELECT count(*) FROM public.fragment where attributes @> '{"cm-handle-state": "READY"}';
 count 
-------
 10000
(1 row)

Now that all CM handles are ready, we can proceed to test de-registration. Go back to Postman.

In Postman, select "De-Register CM handles", and click "Send".
Record the time taken (54.91 s in this case).

Stop docker-compose:

Code Block

language	bash

docker-compose -f docker-compose/docker-compose.yml down

Clean up docker containers and volumes:
Code Block
language bash
docker container prune -f && docker volume prune -f

...

There is a script in the cps repo for automatic testing of NCMP handle de-registration. The script will test registering and de-registering 100, 500, 1000, 5000, 10,000 and 20,000 by default. To use it, simply run the script.

Before testing, you may need to edit docker-compose/docker-compose.yml to filter notifications: set NOTIFICATION_DATASPACE_FILTER_PATTERNS to NON-EXISTING-DATASPACE

Code Block

language	yml

cps-and-ncmp:
  environment:
    notification.enabled: 'true'
    NOTIFICATION_DATASPACE_FILTER_PATTERNS: 'NON-EXISTING-DATASPACE'

Run the script:

Code Block

While the script is running, you may monitor the progress in another terminal. A summary report will be generated at test-tools/metrics-reports/deregister-summary-{CURRENT-DATETIME}.tsv:

Code Block
$ tail -f test-tools/metrics-reports/deregister-summary-2023-03-24T17\:23\:28+00\:00.tsv Removed Total Time 100 100 1.099639 500 500 3.452250 1000 1000 6.132099 5000 5000 25.372256

The script will also produce Prometheus metrics reports for each individual test, stored in test-tools/metrics-reports. For example, this report is generated for de-registering 1000 out of 1000 CM handles: deregister-2023-03-24T17:29:20+00:00-1000-1000.tsv
