A JSON FUZZ Generator in Ruby from JSON Schema files.
This gem is a re-write & renaming of dead-since-2015 json-fuzz-generator,
It has been re-built on top of the modern json_schemer
instead of the unmaintained json-schema.
Add this line to your application's Gemfile:
gem 'json_schemer-fuzz'
And then execute:
$ bundle
Or install it yourself as:
$ gem install json_schemer-fuzz
require "json_schema-fuzz"
json = <<~JSON
{
"title": "Basic Schema",
"type": "object",
"properties": {
"id" : {
"type": "integer",
"minimum": 0
},
"name": {
"type": "string"
},
"birthday": {
"type": "string",
"format": "date"
}
}
}
JSON
schema = JSON.parse(json)
JSONSchemer::Fuzz.default_param(schema)
# => {"id"=>0, "name"=>"hoge", "birthday"=>"1992-06-27"}require "json_schema-fuzz"
json = <<~JSON

This Library adheres to Semantic Versioning 2.0.0. Violations of this scheme should be reported as bugs. Specifically, if a minor or patch version is released that breaks backward compatibility, a new version should be immediately released that restores compatibility. Breaking changes to the public API will only be introduced with new major versions.
