Better using a simpler schema than json-schema, like skema:

import skema
from jsonschema import validate
import json
from hypothesis import given, settings
from hyposchema.hypo_schema import generate_from_schema

EXAMPLE_JSON_SCHEMA=skema.to_jsonschema("""
Root: EventA & EventB
EventA:
    type: Str
    fields:
        args: [
            name: Str
            type: Str | Any
        ]
    ...

EventB:
    timestamp: Any
    sentBy: Str
    madeBy: "me" | "you"
    ...

""", resolve=True)

@given(generate_from_schema(EXAMPLE_JSON_SCHEMA))
@settings(max_examples=10)
def test_basic_map( example_data):
    print(json.dumps(example_data, indent=4))
    validate(example_data, EXAMPLE_JSON_SCHEMA)
