### Question:
AddFieldTransformator extends TransformatorProcess { public void apply(String idProcess, ParameterTransformation parameterTransformation, ObjectNode jsonValue) { put(jsonValue, parameterTransformation.getComposeField().getKey(), parameterTransformation.getComposeField().getValue()); } AddFieldTransformator(); void apply(String idProcess, ParameterTransformation parameterTransformation, ObjectNode jsonValue);  }### Answer:
@Test public void should_Process_Ok() throws Exception { AddFieldTransformator addFieldValidator = new AddFieldTransformator(); RawDataGen rd = RawDataGen.builder().messageSend("gni").project("project").type("type").build(); ObjectMapper obj = new ObjectMapper(); String value = obj.writeValueAsString(rd); ObjectNode jsonValue = JSONUtils.getInstance().parseObj(value); addFieldValidator.apply(null, ParameterTransformation.builder() .composeField(ProcessKeyValue.builder() .key("addField") .value("value") .build() ).build(), jsonValue); assertThat(jsonValue.path("addField").asText()).isEqualTo("value"); }
