### Question:
CapitalizeTransformator extends TransformatorProcess { @Override public void apply(String idProcess, ParameterTransformation parameterTransformation, ObjectNode jsonValue) { if (has(parameterTransformation.getKeyField(), jsonValue)) { JsonNode valueField = at(parameterTransformation.getKeyField(), jsonValue); String capitalized = StringUtils.capitalize(valueField.textValue()); put(jsonValue, parameterTransformation.getKeyField(), capitalized); } } CapitalizeTransformator(); @Override void apply(String idProcess, ParameterTransformation parameterTransformation, ObjectNode jsonValue);  }### Answer:
@Test public void should_Process_Ok() throws Exception { CapitalizeTransformator capitalizeTransformator = new CapitalizeTransformator(); RawDataGen rd = RawDataGen.builder().messageSend("gni gnu").project("project").type("type").build(); ObjectMapper obj = new ObjectMapper(); String value = obj.writeValueAsString(rd); ObjectNode jsonValue = JSONUtils.getInstance().parseObj(value); capitalizeTransformator.apply(null, ParameterTransformation.builder() .keyField("messageSend") .build(), jsonValue); assertThat(jsonValue.path("messageSend").asText()).isEqualTo("Gni gnu"); }
