json-test

A python library for assisting you in writing tests against a JSON structure. The library concentrates on the shape of the JSON structure rather than the actual content in it.

Installation

pip install json_test

Pre-requisite

What you need to know for using the library?

There are two classes JObject and JList which are used to represent Objects and list of JSON.

Let's assume you have a JSON object like this:

{
  "name" : "Joe",
  "age" : 12
}

You have to represent them using JObject like this:

person = JObject(keys=['name', 'age'])

Or

person = JObject(['name', 'age'])

Example for a Nested Object in JSON:

{
  "name" : "Joe",
  "age" : {
            "year" : 24,
            "days" : 174
          }
}

which will be represented like this:

age = JObject(parent = "age", keys=['year','days'])
person = JObject(keys = ['name', age])

Quick Start

from json_test import *

json_string = """
{
  "name" : "Joe",
  "age" : 24
}
"""
json_obj = JObject(['name','age'])

check_json(json_string, json_obj) # This predicate will return True
