Test ONAP API with Postman
==========================

Postman
-------

Postman is a tool that allows a user to run REST API.

The user defines the API requests and has the possibility to group them
in files called a "Collections".

The user can then run each individual API request or run a complete collection.

Postman includes the possibility to define "environment" variables.

An API request can then get or set a value from/to that "environment" variable.

Get and install Postman tool on your own machine (Linux/windows).

Postman is available here: https://www.getpostman.com/


ONAP Postman collections
------------------------

ONAP Integration project provides several Postman collections with two
environment files.

Those Postman Collections will allow a Developer to experiment various ONAP API
on various ONAP components (SDC, NBI, SO, AAI, SDNC)

- declare a vendor
- declare a VSP
- upload a package
- declare a VF based on the VSP
- declare a Service composed of the VF and a Virtual Link
- distribute all those informations
- declare a customer, a service subscription
- declare OwningEntity, Platform...
- declare a Complex, Cloud Region, Tenant
- associate customer/service/tenant
- declare a service instance via a serviceOrder
- declare a vnf
- declare a vf-module
- declare a network

A collection is also provided to delete objects
(reminder: it is not possible to delete object in SDC)

They have been tested with Onap Dublin (they are not all compatible with
Casablanca, and there is not guaranty about ONAP "master" as API definition
can change)


Download ONAP Postman collections
---------------------------------

From your machine, git clone the ONAP Integration project.

::

  git clone "https://gerrit.onap.org/r/integration"


Import ONAP Postman collections
-------------------------------

ONAP Postman collection are in the repository integration/test/postman

Launch Postman tool

import all ONAP Collections into Postman

.. figure:: files/postman/import.png
   :align: center

And you should see all the collections into Postman

.. figure:: files/postman/collections.png
   :align: center

Each collection is made of several API operations

.. figure:: files/postman/collection-detail.png
   :align: center


Running ONAP Postman collections
--------------------------------

Running all those collections, in the order, from 1 to 10 will create a lot of
objects in ONAP components :

- SDC : vendor, VSP, zip file upload, VF from VSP, Service, add VF to Service
- VID : OwningEntity, LineOfBusiness, Project, Platform
- AAI : customer, subscription, cloud region, tenant
- NBI : serviceOrder to add a service instance, serviceOrder to delete
  a service instance

The order is very important because a lot of API requests will need the API
response from the previous operation o get and set some variable values.

.. figure:: files/postman/collection-detail-test.png
   :align: center

It is possible to run the complete collection using Postman

.. figure:: files/postman/run.png
   :align: center

You need, a zip file that contains Heat files for a VNF.

Collection 3 is about uploading that file into ONAP SDC.

.. figure:: files/postman/zipfile.png
   :align: center

Before running those collections, once in Postman, you need to have a look
at "globals" environment parameters.

.. figure:: files/postman/globals.png
   :align: center

All variables that begin by "auto" must NOT be changed (they will be modified
using API response).

All other variables must be adapted to your needs.

In particular, you need to put your own values for cloud_region_id, tenant_name
and tenant_id to fit with the place where you will instantiate the VNF.

Using Newman
------------

Newman is a tool that allow to run postman collections via command-line

On a linux server, with Docker installed on it, run those lines:

::

  git clone https://gitlab.com/Orange-OpenSource/lfn/onap/onap-tests.git
  cd onap-tests/postman
  sudo apt-get -y install zip
  USECASE=$'ubuntu16'
  zip -j $USECASE.zip ../onap_tests/templates/heat_files/$USECASE/*
  TAB=$'\t\t\t\t\t\t\t'
  sed -i -e "s/.*src.*/$TAB\"src\": \"$USECASE.zip\"/" 03_Onboard_VSP_part2.postman_collection.json
  docker pull postman/newman:alpine
  docker run --network="host" --volume="/home/debian/rene/onap-tests/postman:/etc/newman" postman/newman:alpine run 01_Onboard_Vendor.postman_collection.json --environment integration_test_urls.postman_environment.json --globals globals.postman_globals.json --export-globals globals.postman_globals.json --reporters cli,json --reporter-cli-no-assertions --reporter-cli-no-console

  docker run --network="host" --volume="/home/debian/rene/onap-tests/postman:/etc/newman" postman/newman:alpine run 04_Onboard_VSP_part3.postman_collection.json --environment integration_test_urls.postman_environment.json --globals globals.postman_globals.json --export-globals globals.postman_globals.json
  docker run --network="host" --volume="/home/debian/rene/onap-tests/postman:/etc/newman" postman/newman:alpine run 05_Onboard_VF.postman_collection.json --environment integration_test_urls.postman_environment.json --globals globals.postman_globals.json --export-globals globals.postman_globals.json
  docker run --network="host" --volume="/home/debian/rene/onap-tests/postman:/etc/newman" postman/newman:alpine run 06_Onboard_Service.postman_collection.json --environment integration_test_urls.postman_environment.json --globals globals.postman_globals.json --export-globals globals.postman_globals.json

  docker run --network="host" --volume="/home/debian/rene/onap-tests/postman:/etc/newman" postman/newman:alpine run 08_Declare_Customer_Service_Subscription_Cloud.postman_collection.json --insecure --environment integration_test_urls.postman_environment.json --globals globals.postman_globals.json --export-globals globals.postman_globals.json
  docker run --network="host" --volume="/home/debian/rene/onap-tests/postman:/etc/newman" postman/newman:alpine run 10_instantiate_service_vnf_vfmodule.postman_collection.json --environment integration_test_urls.postman_environment.json --globals globals.postman_globals.json --export-globals globals.postman_globals.json --reporters cli,json --reporter-cli-no-assertions --reporter-cli-no-console

All collections are processed, then you can see results and you will
also obtain result json files in the onap-tests/postamn/newman directory

Of course you can adapt globals variables in globals.postman_globals.json
or change the USECASE=$'ubuntu16' value to onboard any heat template located
in onap_tests/templates/heat_files directory
