### Question:
DeleteFieldTransformator extends TransformatorProcess { public void apply(String idProcess, ParameterTransformation parameterTransformation, ObjectNode jsonValue) { remove(jsonValue,parameterTransformation.getKeyField()); } DeleteFieldTransformator(); void apply(String idProcess, ParameterTransformation parameterTransformation, ObjectNode jsonValue);  }### Answer:
@Test public void should_Process_Ok() throws Exception { DeleteFieldTransformator deleteFieldValidator = new DeleteFieldTransformator(); 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); deleteFieldValidator.apply(null, ParameterTransformation.builder() .keyField("project") .build(), jsonValue); assertThat(jsonValue.path("project").asText()).isEqualTo(""); }
