9.4. Conducting ONAP VNF Testing for OVP

9.4.1. Overview

As the LFN verification framework, the Dovetail team has worked with the ONAP VVP, and VTP projects to enable VNF testing, results submission, and results review to be completed throught the same web portal and processes used for the NFVI testing. For more details about VNF SDK and VVP, please refer to ONAP VNF SDK Compliance Verification Program and ONAP VVP.

Testing is available for both HEAT and TOSCA defined VNFs, but the process is different depending on the template language. This userguide covers the testing process for both VNF types in the two sections below.

9.4.2. Definitions and abbreviations

  • LFN - Linux Foundation Networking

  • ONAP - Open Network Automation Platform

  • OVP - OPNFV Verification Program

  • VNF - Virtual Network Function

  • VNF SDK - VNF Software Development Kit

  • VTP - VNF Test Platform

  • VVP - VNF Validation Program

9.4.3. Testing of HEAT based VNFs

9.4.3.1. Environment Preparation

9.4.3.1.1. Prerequisites

  • ONAP ElAlto Release deployed via OOM

  • An OpenStack deployment is available and privisioned as ONAP’s Cloud Site

  • kubectl is installed on the system used to start the testing

  • bash

  • VNF Heat Templates

  • Preload json files

After deploying ONAP, you need to configure ONAP with:

  • A cloud owner

  • A cloud region

  • A subscriber

  • A service type

  • A project name

  • An owning entity

  • A platform

  • A line of business

  • A cloud site

If you’re not familiar with how to configure ONAP, there are guides that use robot or direct api requests available to help, as well as a guide for adding a new OpenStack site to ONAP.

9.4.3.1.2. VVP Test Tool Setup

On your local machine, or the system from which you will run the tests, you will need to clone the ONAP OOM project repo:

git clone --branch 5.0.1-ONAP ssh://<username>@gerrit.onap.org:29418/oom --recurse-submodules

9.4.3.2. VNF Preparation

The vnf lifecycle validation testsuite requires the VNF to be packaged into a specific directory hierarchy, shown below.

vnf_folder
├── /templates
|   └── base.yaml
|   └── base.env
|   └── incremental_0.yaml
|   └── incremental_0.env
|   └── ...
├── /preloads
|   └── base_preload.json
|   └── incremental_0_preload.json
|   └── ...
└── vnf-details.json

  • The name for vnf_folder is free-form, and can be located anywhere on your computer. The path to this folder will be passed to the testsuite as an argument.

  • /templates should contain your VVP-compliant VNF heat templates.

  • /preloads should contain a preload file for each VNF module (TODO: add link to preload documentation).

    • For a VNF-API preload: vnf-name, vnf-type, generic-vnf-type, and generic-vnf-name should be empty strings.

    • For a GR-API preload: vnf-name, vnf-type, vf-module-type, and vf-module-name should be empty strings.

    • This information will be populated at runtime by the testsuite.

  • vnf-details should be a json file with the information that will be used by ONAP to instantiate the VNF. The structure of vnf-details is shown below.

  • VNF disk image must be uploaded and available in the OpenStack project being managed by ONAP

  • Modules must contain an entry for each module of the VNF. Only one module can be a base module.

  • api_type should match the format of the preloads that are provided in the package.

  • The other information should match what was used to configure ONAP during the pre-requisite section of this guide.

    "os_password": "<openstack password>"
}

9.4.3.3. Runnign the HEAT VNF Test

The ONAP OOM Robot framework will run the test, using kubectl to manage the execution. The framework will copy your VNF template files to the robot container required to execute the test.

 cd oom/kubernetes/robot
$ ./instantiate-k8s.sh --help
./instantiate-k8s.sh [options]

required:
-n, --namespace <namespace>       namespace that robot pod is running under.
-f, --folder <folder>             path to folder containing heat templates, preloads, and vnf-details.json.

additional options:
-p, --poll                        some cloud environments (like azure) have a short time out value when executing
                                  kubectl. If your shell exits before the testsuite finishes, using this option
                                  will poll the testsuite logs every 30 seconds until the test finishes.
-t, --tag <tag>                   robot testcase tag to execute (default is instantiate_vnf).

This script executes the VNF instantiation robot testsuite.
- It copies the VNF folder to the robot container that is part of the ONAP deployment.
- It models, distributes, and instantiates a heat-based VNF.
- It copies the logs to an output directory, and creates a tarball for upload to the OVP portal.

Sample execution:

$ ./instantiate-k8s.sh --namespace onap --folder /tmp/vnf-instantiation/examples/VNF_API/pass/multi_module/ --poll
...
...
...
...

VNF test results: /tmp/vnfdata.46749/vnf_heat_results.tar.gz

The testsuite takes about 10-15 minutes for a simple VNF, and will take longer for a more complicated VNF.

9.4.3.3.1. Reporting Results

Once the testsuite is finished, it will create a directory and tarball in /tmp (the name of the directory and file is shown at the end of the stdout of the script). There will be a results.json in that directory that has the ultimate outcome of the test, in the structure shown below.

Log Files

The output tar file will have 4 log files in it.

  • results.json: This is high-level results file of all of the test steps, and is consumed by the OVP portal.

  • report.json: This is the output of the vvp validation scripts.

  • stack_report.json: This is the output from querying openstack to validate the heat modules.

  • log.html: This is the robot log, and contains each execution step of the testcase.

If the result is “PASS”, that means the testsuite was successful and the tarball is ready for submission to the OVP portal.

9.4.3.4. Additional Resources

Sample VNF templates are available on the VVP Wiki Users Guide page.

9.4.4. Testing of TOSCA based VNFs

VNF Test Platform (VTP) provides an platform to on-board different test cases required for OVP for various VNF testing provided by VNFSDK (for TOSCA) and VVP(for HEAT) projects in ONAP. And it generates the test case outputs which would be uploaded into OVP portal for VNF badging.

9.4.4.1. TOSCA VNF Test Environment

As pre-requestiests steps, Its assumed that, successful ONAP, Vendor VNFM and OpenStack cloud are already available. Below installation steps help to setup VTP components and CLI.

../../../_images/tocsa_vnf_test_environment.png

9.4.4.2. Installation

Clone the VNFSDK repo.

git clone --branch elalto https://git.onap.org/vnfsdk/refrepo

Install the VTP by using script refrepo/vnfmarket-be/deployment/install/vtp_install.sh

Follow the steps as below (in sequence):

  • vtp_install.sh –download : It will download all required artifacts into /opt/vtp_stage

  • vtp_install.sh –install : It will install VTP (/opt/controller) and CLI (/opt/oclip)

  • vtp_install.sh –start : It will start VTP controller as tomcat service and CLI as oclip service

  • vtp_install.sh –verify : It will verify the setup is done properly by running some test cases.

Last step (verify) would check the health of VTP components and TOSCA VNF compliance and validation test cases.

9.4.4.2.1. Check Available Test Cases

VTP supports to check the compliance of VNF and PNF based on ONAP VNFREQS.

To check:

  • Go to command console

  • Run command oclip

  • Now it will provide a command prompt:

oclip:open-cli>

Now run command as below and check the supported compliance testcases for VNFREQS.

  • csar-validate - Helps to validate given VNF CSAR for all configured VNFREQS.

  • csar-validate-rxxx - Helps to validate given VNF CSAR for a given VNFREQS xxx.

oclip:open-cli>schema-list --product onap-dublin --service vnf-compliance
+--------------+----------------+------------------------+--------------+----------+------+
|product       |service         |command                 |ocs-version   |enabled   |rpc   |
+--------------+----------------+------------------------+--------------+----------+------+
|onap-dublin   |vnf-compliance  |csar-validate-r10087    |1.0           |true      |      |
+--------------+----------------+------------------------+--------------+----------+------+
|onap-dublin   |vnf-compliance  |csar-validate           |1.0           |true      |      |
+--------------+----------------+------------------------+--------------+----------+------+
|onap-dublin   |vnf-compliance  |csar-validate-r26885    |1.0           |true      |      |
+--------------+----------------+------------------------+--------------+----------+------+
|onap-dublin   |vnf-compliance  |csar-validate-r54356    |1.0           |true      |      |
...

To know the details of each VNFREQS, run as below.

oclip:open-cli>use onap-dublin
oclip:onap-dublin>csar-validate-r54356 --help
usage: oclip csar-validate-r54356

Data types used by NFV node and is based on TOSCA/YAML constructs specified in draft GS NFV-SOL 001.
The node data definitions/attributes used in VNFD MUST comply.

Now run command as below and check the supported validation testcases

oclip:onap-dublin>use open-cli
oclip:open-cli>schema-list --product onap-dublin --service vnf-validation
+--------------+----------------+----------------------+--------------+----------+------+
|product       |service         |command               |ocs-version   |enabled   |rpc   |
+--------------+----------------+----------------------+--------------+----------+------+
|onap-dublin   |vnf-validation  |vnf-tosca-provision   |1.0           |true      |      |
+--------------+----------------+----------------------+--------------+----------+------+

9.4.4.2.2. Configure ONAP with required VNFM and cloud details

1. Setup the OCOMP profile onap-dublin

Run following command to configure the ONAP service URL and creadentials as given below, which will be used by VTP while executing the test cases

oclip:open-cli>use onap-dublin
oclip:onap-dublin>profile onap-dublin
oclip:onap-dublin>set sdc.onboarding:host-url=http://159.138.8.8:30280
oclip:onap-dublin>set sdc.onboarding:host-username=cs0008
oclip:onap-dublin>set sdc.onboarding:host-password=demo123456!
oclip:onap-dublin>set sdc.catalog:host-url=http://159.138.8.8:30205
oclip:onap-dublin>set sdc.catalog:host-password=demo123456\!
oclip:onap-dublin>set sdc.catalog:host-username=cs0008
oclip:onap-dublin>set sdc.catalog:service-model-approve:host-username=gv0001
oclip:onap-dublin>set sdc.catalog:service-model-distribute:host-username=op0001
oclip:onap-dublin>set sdc.catalog:service-model-test-start:host-username=jm0007
oclip:onap-dublin>set sdc.catalog:service-model-test-accept:host-username=jm0007
oclip:onap-dublin>set sdc.catalog:service-model-add-artifact:host-username=ocomp
oclip:onap-dublin>set sdc.catalog:vf-model-add-artifact:host-username=ocomp
oclip:onap-dublin>set aai:host-url=https://159.138.8.8:30233
oclip:onap-dublin>set aai:host-username=AAI
oclip:onap-dublin>set aai:host-password=AAI
oclip:onap-dublin>set vfc:host-url=http://159.138.8.8:30280
oclip:onap-dublin>set multicloud:host-url=http://159.138.8.8:30280

NOTE: Mostly all above entries value would be same execept the IP address used in the URL, which would be ONAP k8s cluser IP.

By default, SDC onboarding service does not provide node port, which is available to access from external ONAP network. so to enable for external access, register the SDC onboarding service into MSB and use MSB url for sdc.onboarding:host-url.

oclip:onap-dublin> microservice-create --service-name sdcob --service-version v1.0 --service-url /onboarding-api/v1.0 --path /onboarding-api/v1.0 --node-ip 172.16.1.0 --node-port 8081

NOTE: To find the node-ip and node-port, use the following steps.

Find out SDC onboarding service IP and port details as given here:

[root@onap-dublin-vfw-93996-50c1z ~]# kubectl get pods -n onap -o wide | grep sdc-onboarding-be
dev-sdc-sdc-onboarding-be-5564b877c8-vpwr5 2/2 Running 0 29d 172.16.1.0 192.168.2.163 <none> <none>
dev-sdc-sdc-onboarding-be-cassandra-init-mtvz6 0/1 Completed 0 29d 172.16.0.220 192.168.2.163 <none> <none>
[root@onap-dublin-vfw-93996-50c1z ~]#

Note down the IP address for sdc-onboarding-be 172.16.1.0

[root@onap-dublin-vfw-93996-50c1z ~]# kubectl get services -n onap -o wide | grep sdc-onboarding-be
sdc-onboarding-be ClusterIP 10.247.198.92 <none> 8445/TCP,8081/TCP 29d app=sdc-onboarding-be,release=dev-sdc
[root@onap-dublin-vfw-93996-50c1z ~]#

Note down the port for sdc-onboarding-be 8445 8081

Similarly, other service IP and Port could be discovered like above, in case not know earlier :)

Verify these details once by typing ‘set’

oclip:onap-dublin> set

This profile would be used by user while running the test cases with ONAP setup configured in it, as below oclip –profile onap-dublin vnf-tosca-provision ….

2. Setup SDC consumer

SDC uses consumer concept to configure required VN model and service model artifacts. So following commands required to run, which will create consumer named ocomp, which is already configured in onap-dublin profile created in above steps.

oclip --product onap-dublin --profile onap-dublin sdc-consumer-create --consumer-name ocomp

NOTE: command oclip could be used in scripting mode as above or in interactive mode as used in earlier steps

3. Update the cloud and vnfm driver details

In the configuration file /opt/oclip/conf/vnf-tosca-provision.json, update the cloud and VNFM details.

"cloud": {
        "identity-url": "http://10.12.11.1:5000/v3",
        "username": "admin",
        "password": "password",
        "region": "RegionOVP",
        "version": "ocata",
        "tenant": "ocomp"
    },
    "vnfm":{
        "hwvnfmdriver":{
            "version": "v1.0",
            "url": "http://159.138.8.8:38088",
            "username": "admin",
            "password": "xxxx"
        },
        "gvnfmdriver":{
            "version": "v1.0",
            "url": "http://159.138.8.8:30280"
        }
    }

4.Configure the decided VNFRES (optional) VTP allows to configure the set of VNFREQS to be considered while running the VNF compliance test cases in the configuration file /opt/oclip/conf/vnfreqs.properties.

If not available, please create this file with following entries:

vnfreqs.enabled=r02454,r04298,r07879,r09467,r13390,r23823,r26881,r27310,r35851,r40293,r43958,r66070,r77707,r77786,r87234,r10087,r21322,r26885,r40820,r35854,r65486,r17852,r46527,r15837,r54356,r67895,r95321,r32155,r01123,r51347,r787965,r130206
pnfreqs.enabled=r10087,r87234,r35854,r15837,r17852,r293901,r146092,r57019,r787965,r130206
# ignored all chef and ansible related tests

pnferrors.ignored=

9.4.4.3. Runnign the TOSCA VNF Test

Every test provided in VTP is given with guidelines on how to use it. On every execution of test cases, use the following additional arguments based on requirements

  • –product onap-dublin - It helps VTP choose the test cases written for onap-dublin version

  • –profile onap-dublin - It helps VTP to use the profile settings provided by admin (optional)

  • –request-id - It helps VTP to track the progress of the test cases execution and user could use this id for same. (optional)

So, final test case execution would be as below. To find the test case arguments details, run second command below.

oclip --product onap-dublin --profile onap-dublin --request-id req-1 <test case name> <test case arguments>
oclip --product onap-dublin <test case name> --help

9.4.4.3.1. Running TOSCA VNF Compliance Testing

To run compliance test as below with given CSAR file

It will produce the result format as below:

{
    "date": "Fri Sep 20 17:34:24 CST 2019",
    "criteria": "PASS",
    "contact": "ONAP VTP Team onap-discuss@lists.onap.org",
    "results": [
    {
        "description": "V2.4.1 (2018-02)",
        "passed": true,
        "vnfreqName": "SOL004",
        "errors": []
    },
    {
        "description": "If the VNF or PNF CSAR Package utilizes Option 2 for package security, then the complete CSAR file MUST be digitally signed with the VNF or PNF provider private key. The VNF or PNF provider delivers one zip file consisting of the CSAR file, a signature file and a certificate file that includes the VNF or PNF provider public key. The certificate may also be included in the signature container, if the signature format allows that. The VNF or PNF provider creates a zip file consisting of the CSAR file with .csar extension, signature and certificate files. The signature and certificate files must be siblings of the CSAR file with extensions .cms and .cert respectively.\n",
        "passed": true,
        "vnfreqName": "r787965",
        "errors": []
    }
    ],
    "platform": "VNFSDK - VNF Test Platform (VTP) 1.0",
    "vnf": {
    "mode": "WITH_TOSCA_META_DIR",
    "vendor": "ONAP",
    "name": null,
    "type": "TOSCA",
    "version": null
    }
}

In case of errors, the errors section will have list of details as below. Each error block, will be given with error code and error details. Error code would be very useful to provide the troubleshooting guide in future. Note, to generate the test result in OVP archieve format, its recommended to run this compliance test with request-id similar to running validation test as below.

[
{
    "vnfreqNo": "R66070",
    "code": "0x1000",
    "message": "MissinEntry-Definitions file",
    "lineNumber": -1
}
]

9.4.4.3.2. Running TOSCA VNF Validation Testing

VTP provides validation test case with following modes:

../../../_images/tosca_vnf_test_flow.png

setup: Create requires Vendor, Service Subscription and VNF cloud in ONAP standup: From the given VSP csar, VNF csar and NS csar, it creates VF Model, NS Model and NS service cleanup: Remove those entries created during provision provision: Runs setup -> standup validate: Runs setup -> standup -> cleanup checkup: mode helps to verify automation is deployed properly.

For OVP badging, validate mode would be used as below:

oclip --request-id WkVVu9fD--product onap-dublin --profile onap-dublin vnf-tosca-provision --vsp <vsp csar> --vnf-csar <v

Validation testing would take for a while to complete the test execution, so user could use the above given request-id, to tracking the progress as below:

While executing the test cases, VTP provides unique execution-id (2nd column) for each step. As you note in the example above, some steps are in-progress, while others are completed already. If there is error then status will be set to failed.

To find out the foot-print of each step, following commands are available

oclip execution-show-out --execution-id WkVVu9fD-1568731785780       - Reports the standard output logs
oclip execution-show-err --execution-id WkVVu9fD-1568731785780        - Reports the standard error logs
oclip execution-show-debug --execution-id WkVVu9fD-1568731785780  - Reports the debug details like HTTP request and responseoclip execution-show --execution-id WkVVu9fD-1568731785780              - Reports the complete foot-print of inputs, outputs of steps

Track the progress of the vnf-tosca-provision test cases until its completed. Then the out of the validation test cases could be retrieved as below:

oclip execution-show --execution-id WkVVu9fD-1568731678753              - use vnf tosca test case execution id here

It will provides the output format as below:

9.4.4.3.3. Reporting Results

VTP provides translation tool to migrate the VTP result into OVP portal format and generates the tar file for the given test case execution. Please refer https://github.com/onap/vnfsdk-refrepo/tree/master/vnfmarket-be/deployment/vtp2ovp for more details.

Once tar is generated, it can be used to submit into OVP portal https://vnf-verified.lfnetworking.org/
