    SchemaAndValue schemaAndValue = converter.toConnectData(TOPIC, msg.getBytes());
    assertEquals(schema, schemaAndValue.schema());
    assertEquals(reference, schemaAndValue.value());
}

Example 2 with Schema

    JsonNode converted = parse(converter.fromConnectData(TOPIC, int32Array, Arrays.asList(1, 2, 3)));
    validateEnvelope(converted);
    assertEquals(parse("{ \"type\": \"array\", \"items\": { \"type\": \"int32\", \"optional\": false }, \"optional\": false }"), converted.get(JsonSchema.ENVELOPE_SCHEMA_FIELD_NAME));
