JsonSchemaDraft4

Generates JSON data that conforms to a configured JSON Schema Draft 4 document.

What It Does

Generates JSON documents from a Draft 4 JSON schema and then applies the same field-replacement system used by the regular Json generator.

This is useful when you want structurally valid random test data but still need certain fields pinned to known values. An optional seed makes the random generation repeatable across runs.

YAML Example

DataSources:
  - Name: OrderSchema
    Generator: FromFileSystem
    Deserialize:
      Deserializer: Json
    GeneratorConfiguration:
      DataArrangeOrder: AsciiAsc
      FileSystem:
        Path: sample-data/json-schema
        SearchPattern: 'order-schema.json'
      StorageMetaData: ItemName

  - Name: GeneratedSchemaOrders
    Generator: JsonSchemaDraft4
    DataSourceNames:
      - OrderSchema
    GeneratorConfiguration:
      JsonDataSourceName: OrderSchema
      Count: 3
      Seed: 42
      JsonFieldReplacements:
        - Path: $.priority
          ValueType: String
          String:
            Value: high

What This Configuration Does

This example reads a Draft 4 schema from order-schema.json, generates three schema-valid JSON documents from it, and then forces the priority field in each document to high.

Because the seed is fixed to 42, the random parts of the generated payloads stay repeatable between runs.
