Overview

For testing SDN-R with its basic use cases an automated test setup should be used. 

Beside "SDN-R Development integratoin test" there is the "SDN-R Solution integration test"

Related issue: 

Requirements

• Simple, run on single ubuntu server 
• Use Simulators instead of devices
• Use as far as possible real ONAP server components, if not possible test tools, like VES-test-collector
• Is compatible with ONAP integration tests setup

  • Port ranges 8310 .. 8499, 40000 .. 49999
  • ntssim oran 8310, 40000 .. 40019
• Docker internal static IP assignment in "integration" network (172.40.0.0/16) with names for /etc/hosts of docker host.
  • 172.40.0.20 sdnrinit
  • 172.40.0.21 sdnr

• NTSim/ORan is using its own network. Communication takes place over the host IP and the mapped ports.
  • 172.17.02 container with 10 ORan devices
• Access to services from outsite are running over the host IP. See table.

Network setup

Development (old environment)

• docker for networking, run containers
• docker-compose starting a structure
• bash initialization
• manuel manual execution of development tests

Test cases

Executed by Jenkins (http://10.20.6.10:30080/view/INT_SDNC_FRANKFURT/) job: INT_SDNC_Frankfurt

Test case "Mount devices" (basic) >available<

• Startup
  • Mount NTSim manager
  • Create and mount two NTSim/"oran" devices
• Test steps
  • Verify that mount of the two devices was successfully done

Test case "Mount and get alarms for 50 devices" (load)

• Startup
  • Mount 10 devices at a time
  • Mount with delay next 10 devices till we have the 50
• Test seps
  • wait till startup is done
  • count the current alarms
  • Test Ok if current alarms count in a expected range.

Test case "Inventory" (functional)

• Startup
  • Create docker network
    • a static network setup with static IPs for the containers
    • add name to hosts and use this names
  • start docker - Simulator (e.g. Sim12600 with equipment)
  • start docker - DB
  • start docker - SDNC
• Test steps
  • mount sim12600
  • Read over the RESTCONF Interface via data-provider the equipment
  • Compare if it is the expected data

Network Topology Simulator

Instantiating NetConf simulators

• New NetConf simulators can be instantiated using the NTS Manager as follows - 
  • Create a mountpoint in SDNR to mount the NTS Manager with the following parameters - 
    • Name - "NTS_Manager" (No double quotes. Any name is OK, see below)
    • IP Address - NTS Manager Docker container IP or Host IP of the Docker container
    • Port - NTS Manager Docker container port or the port mapped to the Host
    • Username - netconf
    • Password - netconf
  • Next, Use any REST Client to send PUT requests
  • Set the "content-type" to "Application/json"
  • Copy the following json into the body of the REST request - 

{
       "simulator-config": {
                  "mounted-devices": 0,
                  "notification-config": {
                         "fault-notification-delay-period": 0,
                         "is-netconf-available": true,
                         "is-ves-available": true,
                         "ves-heartbeat-period": 0
                   },
                  "simulated-devices": 0, # Toggle this value between 0 and any number greater than 0 to create and remove docker containers that send pnfRegistration VES messages to a VES Collector whose IP is                                                                           # configured using the "ves-endpoint-ip" field below
                  "ves-endpoint-details": {
                          "ves-endpoint-port": 8080,
                          "ves-registration": true,
                          "ves-endpoint-auth-method": "no-auth",
                          "ves-endpoint-ip": "10.20.5.5"
                  },
                 "controller-details": {
                          "controller-ip": "172.40.0.21",
                          "controller-port": 8181,
                          "controller-username": "admin",
                          "controller-password": "admin"
                 }
       }
}

•  Set the URL to - http://<SDNR-IP>:<SDNR-PORT>/restconf/config/network-topology:network-topology/topology/topology-netconf/node/<NTS Manager Mountpoint Name>/yang-ext:mount/network-topology-simulator:simulator-config
• Submit the request
• A "docker ps" should display new docker container(s) created with 10 ports per container, representing the simulated device(s)
