Tests with Robot Framework

The .robot scripts in this folder perform integration tests of the mso-lo application against a real instance of a NFVO or RANO.

The test suites included are:

• MSO-LO-NFVO-Workflow: tests the retrieval of information about NFVOs
• MSO-LO-LCM-Workflow: tests the complete LCM of a Network Service in a NFVO (includes subscriptions to notifications)
• MSO-LO-LCM-RANO-Workflow: tests the complete LCM of slice in a RANO
• MSO-LO-SUBS: tests the retrieval of information about subscriptions.

Prerequisites

To execute the tests you need:

• An instance of mso-lo up and running
• An instance of a real NFVO or RANO
• An instante of the IWF Repository
• Correct communication between the components above

Configuration

Check the file variables.robot. Variables that can be customized are provided at the beginning of the file.

Note: use at least 4 spaces between variable name and value, or use tabs

Setup the protocol, host and port where mso-lo application is listening.

${MSO-LO_HOST}      localhost
${MSO-LO_PORT}      80
${HTTP}    http

Choose what type of orchestrator you want to test, nfvo or rano, and provide its ID. The ID comes from the IWF Repository.

${apiRoot}        nfvo
${nfvoId}         1

In the IWF Repository, set the credentials for your orchestrator. Assuming the values above, and that the IWF Repository is hosted at localhost:8087:

curl --request PATCH \
  --url http://localhost:8087/nfvOrchestrators/1 \
  --header 'Content-Type: application/json' \
  --data '{
	"credentials": {
		"host": "192.168.100.2",
		"port": 9999,
		"username": "admin",
		"password": "admin",
		"project": "admin"
	}
}'

Select the UUID of the NSD you want to deploy for the test. It must be available in your NFVO or RANO catalog.

${nsdId}    5821d426-4c51-4be0-a849-5218a09f0d72

Optional

The following settings can be used to associate a Virtual Link of your NSD to a network existing on your VIM. Please provide both names or remove/comment the two lines.

Note: If you want to use this you also need to register your network in the IWF repository.

${vimNetworkName}   test
${vldName}          mgmt_vl

The following setting is used to deploy the VNFs of your service on multiple VIMs available in your NFVO/RANO. Please provide the UUIDs as shown below or remove/comment the line.

${vimAccountIds}    ['64690905-0fe0-4dc4-967c-292eb497e46f', '444bd22e-dd1a-4672-b12b-2604f21f50e6']

Script MSO-LO-LCM-Workflow.robot contains a workflow that instantiates and terminates a Network Service on the configured NFVO. Some test cases include features to wait for the NS to be deployed. Maximum waiting time is set to 2 minutes. You can increase it if it is not enough:

${MAX_WAIT}   2 min

MSO-LO can send notifications about the operation status to an endpoint. You can set it with:

${notificationUri}   http://192.168.18.14:8083/

Execution:

$ cd {project-dir}/adaptation_layer
# activate the virtual env
$ pipenv shell
$ cd ./robotframework
# export mso-lo openapi file path relative to this directory
$ export OPENAPI_PATH=../../openapi/MSO-LO-swagger-resolved.yaml
$ robot --outputdir output MSO-LO-LCM-Workflow.robot MSO-LO-NFVO-Workflow.robot
