#JSON Faker

A provider extension for the fantastic Faker-Factory module. Instead of creating discrete values of a particular type or utility, it uses JSON Schemas to generate structures with multiple key-value pairs and hierarchy in JSON markup.

In addition to Faker-Factory, the JSON Faker also uses the rstr module.

I have used this for integration testing and fuzzing RESTful APIs.

###Example script: This will generate some random JSON based on the resource.schema and POSTs it to https://www.some.api/resource

import JSONFaker
import requests
import faker
import sys
import json

fake = faker.Faker()
fake.add_provider(JSONFaker.JSONProvider)

response = requests.post(sys.argv[1], 
						 data=fake.json(json.load(open(sys.argv[2]))))
						 
assert(response.status_code == 200), "Error: Response code was {}".format(response.status_code)

sys.exit(0)

# python example.py https://www.some.api/resource pat/to/some/resource.schema

###Requirements & Installation

• Python 2.7
• pip
• virtualenv strongly recommended

pip install -r requirements.txt will install all of the required support libraries.

[Cat the schema]

(jsonprovider)pickard@Pocket-2 ~/projects> cat JSONFaker/example_schemas/globalreach_registration.requestschema.json | python -mjson.tool
{
    "$schema": "http://json-schema.org/draft-04/schema#",
    "additionalproperties": false,
    "properties": {
        "emailaddress": {
            "description": "The email address of the registrant",
            "type": "string"
        },
        "macaddress": {
            "description": "The MAC address of the registrant device, encrypted",
            "pattern": "^ENC[0-9a-f]{48}",
            "type": "string"
        },
        "uuid": {
            "description": "The generated client identifier generated by GlobalReach",
            "type": "string"
        }
    },
    "required": [
        "emailaddress",
        "macaddress",
        "uuid"
    ],
    "title": "Global Reach LinkNYC registration request Schema",
    "type": "object"
}
