Python JSON dummy data generation from JSON schema

Question

I am looking for a python library in which I can feed in my JSON schema and it generates dummy data. I have worked with a similar library in javascript dummy-json. Does anyone about a library which can do the same in python.

Answer 1

A library that does exactly this is hypothesis-jsonschema

Hypothesis is a library that can generate arbitrary data that conforms to a given specification.

hypothesis-jsonschema makes it possible to convert JSON Schema into specifications that can be used by Hypothesis.

Here is an example showing a unit test written using Hypothesis and hypothesis-jsonschema:

from hypothesis import given

from hypothesis_jsonschema import from_schema


@given(from_schema({"type": "integer", "minimum": 1, "exclusiveMaximum": 10}))
def test_integers(value):
    assert isinstance(value, int)
    assert 1 <= value < 10

Answer 2

The most closest what I found within python is https://github.com/ueg1990/faker-schema, but it is not JSON-SCHEMA also there is nodejs implementation that is directly what you are searching for https://github.com/json-schema-faker/json-schema-faker

Answer 3

here are the JSON schema generators proposed so far:

• https://github.com/gonvaled/jskemator (1 input but allows iteration)
• https://github.com/perenecabuto/json_schema_generator (1 input)
• https://github.com/rnd0101/json_schema_inferencer (1 input I think)
• https://github.com/wolverdude/GenSON/ (multiple inputs)
• https://pypi.python.org/pypi/skinfer (multiple inputs)

bonus:

• http://www.jsonschema.net (1 input)
