### Question:
KettleObjectMapper { public <T> T readValue( String json, Class<T> clazz ) throws IOException { return mapper.readValue( json, clazz ); } KettleObjectMapper( List<StdSerializer> serializers, List<StdDeserializer> deserializers ); T readValue( String json, Class<T> clazz ); String writeValueAsString( Object obj );  }### Answer:
@Test public void testReadValue() throws Exception { StdDeserializer deserializer = new TransMetaJsonDeserializer( TransMeta.class, null ); deserializers.add( deserializer ); mapper = new KettleObjectMapper( null, deserializers ); assertNotNull( mapper ); mapper.readValue( TRANS_JSON, TransMeta.class ); }
