### Question:
ResourceRecipeRequest { @Override public String toString() { ObjectMapper mapper = new ObjectMapper(); mapper.configure(SerializationFeature.WRAP_ROOT_VALUE, true); String jsonStr = "ResourceRecipeRequest"; try { jsonStr = mapper.writeValueAsString(this); } catch (JsonProcessingException e) { logger.error("JsonProcessingException", e); } return jsonStr; }  @JsonProperty("resourceInput") BpmnParam getResourceInput(); @JsonProperty("resourceInput") void setResourceInput(BpmnParam resourceInput); @JsonProperty("host") BpmnParam getHost(); @JsonProperty("host") void setHost(BpmnParam host); @JsonProperty("mso-request-id") BpmnParam getRequestId(); @JsonProperty("mso-request-id") void setRequestId(BpmnParam requestId); @JsonProperty("requestAction") BpmnParam getRequestAction(); @JsonProperty("requestAction") void setRequestAction(BpmnParam requestAction); @JsonProperty("serviceInstanceId") BpmnParam getServiceInstanceId(); @JsonProperty("serviceInstanceId") void setServiceInstanceId(BpmnParam serviceInstanceId); @JsonProperty("serviceType") BpmnParam getServiceType(); @JsonProperty("serviceType") void setServiceType(BpmnParam serviceType); @JsonProperty("recipeParams") BpmnParam getRecipeParams(); @JsonProperty("recipeParams") void setRecipeParams(BpmnParam recipeParams); @JsonProperty("mso-service-request-timeout") BpmnIntegerParam getRecipeTimeout(); @JsonProperty("mso-service-request-timeout") void setRecipeTimeout(BpmnIntegerParam recipeTimeout); @Override String toString();  }### Answer:
@Test public void testToString() { assert (rr.toString() != null); }
