mokito testing for try catch block in junit-java

In the following file, i want to test the try method code block, using mockito. i want to test the mongo.java file using the j unit-mocking. SoaXMLLoggerRequestDTO is the model class file, and mongo.java is the class file having the method logRequestResponseXMLsWithTimeStamps.
mongo.java
public void logRequestResponseXMLsWithTimeStamps(final String requestType, final String requestXML,
final String responseXML, final long startTime, final long endTime, final long timeTaken,
final String status, final String userId, final String estimatetId) {
try {
SoaXMLLoggerRequestDTO loggerDTO = new SoaXMLLoggerRequestDTO();
loggerDTO.setRequestType(requestType);
loggerDTO.setRequestXml(requestXML);
loggerDTO.setResponseXml(responseXML);
loggerDTO.setCreatedBy(userId);
loggerDTO.setEstimateId(estimatetId + "");
loggerDTO.setStatus(status);
loggerDTO.setLatency(timeTaken);
LogExecutorService.writeToLog(new ESLoggerTask(loggerDTO, ESLoggerTask.IndexName.BNPSOALOG));
} catch (Exception e) {
LOGGER.error("Error in logRequestResponseXMLsWithTimeStamps : ", e);
throw new DAOException("Error logRequestResponseXMLs", e);
}
}
SoaXMLLoggerRequestDTO
public class SoaXMLLoggerRequestDTO extends LoggerRequestDTO{
private String requestType;
private String requestXml;
private String responseXml;
private Long latency;
private String status;
private String estimateId;
public String getRequestType() {
return requestType;
}
public void setRequestType(String requestType) {
this.requestType = requestType;
}
public String getRequestXml() {
return requestXml;
}
public void setRequestXml(String requestXml) {
this.requestXml = requestXml;
}
public String getResponseXml() {
return responseXml;
}
public void setResponseXml(String responseXml) {
this.responseXml = responseXml;
}
public Long getLatency() {
return latency;
}
public void setLatency(Long latency) {
this.latency = latency;
}
public String getStatus() {
return status;
}
public void setStatus(String status) {
this.status = status;
}
public String getEstimateId() {
return estimateId;
}
public void setEstimateId(String estimateId) {
this.estimateId = estimateId;
}
}

The following code will test the try block code.
public void test_logRequestResponseXMLsWithTimeStamps() {
estimateServicesMongoDao.logRequestResponseXMLsWithTimeStamps("ert", "rtr", "werffer",2L,0, 0, "drgfdf","sefw", null);

Retrofit + Observable - Expected BEGIN_ARRAY but was BEGIN_OBJECT

I'm trying to use New York Times API with Retrofit using Observable. But I'm getting this error when trying to use datas.
Can someone help me see where I'm wrong, please ?
Here is my ApiServices interface:
#GET("svc/topstories/v2/home.json?api-key=HiddenApiKeyJustForThisMessage")
Observable<TopStoryResult> getTopStories();
#GET("svc/topstories/v2/home.json?api-key=HiddenApiKeyJustForThisMessage")
Observable<List<NewsItem>> getResults();
Retrofit retrofit = new Retrofit.Builder()
.baseUrl("https://api.nytimes.com/")
.addConverterFactory(GsonConverterFactory.create(new GsonBuilder().excludeFieldsWithoutExposeAnnotation().create()))
.addCallAdapterFactory(RxJava2CallAdapterFactory.create())
.build();
Here is my ApiStreams class
public static Observable<TopStoryResult> streamFetchTopStories(){
ApiServices mApiServices = ApiServices.retrofit.create(ApiServices.class);
return mApiServices.getTopStories()
.subscribeOn(Schedulers.io())
.observeOn(AndroidSchedulers.mainThread())
.timeout(10, TimeUnit.SECONDS);
}
public static Observable<List<NewsItem>> streamFetchNews(){
ApiServices mApiServices = ApiServices.retrofit.create(ApiServices.class);
return mApiServices.getResults()
.subscribeOn(Schedulers.io())
.observeOn(AndroidSchedulers.mainThread())
.timeout(10, TimeUnit.SECONDS);
}
And this is what I'm trying to do in my MainActivity. For now I just want to display in a TextView the list of each Title...
//------------------------
// Update UI
//------------------------
private void updateUIWhenStartingHttpRequest() {
this.textView.setText("Downloading...");
}
private void updateUIWhenStopingHttpRequest(String response) {
this.textView.setText(response);
}
//------------------------
// Rx Java
//------------------------
private void executeRequestWithRetrofit(){
this.updateUIWhenStartingHttpRequest();
this.disposable = ApiStreams.streamFetchNews()
.subscribeWith(new DisposableObserver<List<NewsItem>>(){
#Override
public void onNext(List<NewsItem> topStories) {
Log.e("TAG", "On Next");
updateUIWithResult(topStories);
}
#Override
public void onError(Throwable e) {
Log.e("ERROR", Log.getStackTraceString(e));
}
#Override
public void onComplete() {
Log.e("TAG", "On Complete !");
}
});
}
private void updateUIWithResult(List<NewsItem> newsItemList){
StringBuilder mStringBuilder = new StringBuilder();
for (NewsItem news : newsItemList){
Log.e("TAG", "UPDATE UI" + news.getTitle());
mStringBuilder.append("- " + news.getTitle() + "\n");
}
updateUIWhenStopingHttpRequest(mStringBuilder.toString());
}

First when I tried this one with Github user API, it works fine. But I can't figure out where I'm wrong there...
Is anybody can help me please ?
Thanks a lot !

Expected BEGIN_ARRAY but was BEGIN_OBJECT
this means you are trying to a get a JSON Array as a List in JAVA but the api sent you a JSON OBJECT. So I cannot gather enough information but if I have to guess you should change this
#GET("svc/topstories/v2/home.json?api-key=HiddenApiKeyJustForThisMessage")
Observable<List<NewsItem>> getResults();
to
#GET("svc/topstories/v2/home.json?api-key=HiddenApiKeyJustForThisMessage")
Observable<NewsItemObject> getResults();
NewsItemObject is the Class that wraps NewsItem

In your ApiServices interface you expect that getResults() returns Observable<List<NewsItem>>. Based on JSON you getting back this is not gonna work, because your root JSON element is Object, not an Array.
You have to create new wrapper Class (ResultsWrapper) with "results" field type of List<NewsItem>. Your method in ApiServices interface will then be:
#GET("svc/topstories/v2/home.json?api-key=HiddenApiKeyJustForThisMessage")
Observable<ResultsWrapper> getResults();
That is what "Expected BEGIN_ARRAY but was BEGIN_OBJECT" says to you.

I know enough to realise that a large number of variables, ingredients and measures (many of which are empty) is the wrong approach but i'm struggling to find a solution with retrofit to create an array of these values. I've not found any way to assign multiple SerializedNames to a single array variable?
The option that jumps out at me is looping through the response pulling out the key values in onSuccess but this seems to go against the simplicity of using retrofit?

Realm and Expected BEGIN_OBJECT but was NUMBER at path $[0].location.coordinates[0]

I'm trying to store a coordnates (array of double) using Realm-java,but I'm not able to do it.
Here is an example of json that I'm trying to parse:
{"_id":"597cd98b3af0b6315576d717",
"comarca":"string",
"font":null,
"imatge":"string",
"location":{
"coordinates":[41.64642,1.1393],
"type":"Point"
},
"marca":"string",
"municipi":"string",
"publisher":"string",
"recursurl":"string",
"tematica":"string",
"titol":"string"
}
My global object code is like that
public class Images extends RealmObject implements Serializable {
#PrimaryKey
private String _id;
private String recursurl;
private String titol;
private String municipi;
private String comarca;
private String marca;
private String imatge;
#Nullable
private Location location;
private String tematica;
private String font;
private String parentRoute;
public Location getLocation() {return location;}
public void setLocation(Location location) {this.location = location;}
public String getParentRoute() {
return parentRoute;
}
public void setParentRoute(String parentRoute) {
this.parentRoute = parentRoute;
}
public String get_id() {
return _id;
}
public void set_id(String _id) {
this._id = _id;
}
public String getFont() {
return font;
}
public void setFont(String font) {
this.font = font;
}
public String getRecursurl() {
return recursurl;
}
public void setRecursurl(String recursurl) {
this.recursurl = recursurl;
}
public String getTitol() {
return titol;
}
public void setTitol(String titol) {
this.titol = titol;
}
public String getMunicipi() {
return municipi;
}
public void setMunicipi(String municipi) {
this.municipi = municipi;
}
public String getComarca() {
return comarca;
}
public void setComarca(String comarca) {
this.comarca = comarca;
}
public String getMarca() {
return marca;
}
public void setMarca(String marca) {
this.marca = marca;
}
public String getImatge() {
return imatge;
}
public void setImatge(String imatge) {
this.imatge = imatge;
}
public String getTematica() {
return tematica;
}
public void setTematica(String tematica) {
this.tematica = tematica;
}
And Location is a composite of type and a realmlist
Location.java
public class Location extends RealmObject implements Serializable {
private String type;
private RealmList<RealmDoubleObject> coordinates;
public Location() {
}
public String getType() {
return type;
}
public void setType(String type) {
this.type = type;
}
public RealmList<RealmDoubleObject> getCoordinates() {
return coordinates;
}
public void setCoordinates(RealmList<RealmDoubleObject> coordinates) {
this.coordinates = coordinates;
}
}
RealmDoubleObject.java
public class RealmDoubleObject extends RealmObject implements Serializable{
private Double value;
public RealmDoubleObject() {
}
public Double getDoublevalue() {
return value;
}
public void setDoublevalue(Double value) {
this.value = value;
}
}
The error is com.google.gson.JsonSyntaxException: java.lang.IllegalStateException: Expected BEGIN_OBJECT but was NUMBER at path $[0].location.coordinates[0] but I'm not able to figure out why this number is not "fitting" by RealmDoubleObject.
For those that not familiar with realm RealmList doesn't work and you have to build your own realm object.
Thank you. I hope to find some Realm experts here!

SOLVED:
using Gson deserializer it can be done
First we have to initialize the gson object like this
Gson gson = new GsonBuilder()
.setExclusionStrategies(new ExclusionStrategy() {
#Override
public boolean shouldSkipField(FieldAttributes f) {
return f.getDeclaringClass().equals(RealmObject.class);
}
#Override
public boolean shouldSkipClass(Class<?> clazz) {
return false;
}
})
.registerTypeAdapter(new TypeToken<RealmList<RealmDoubleObject>>() {}.getType(), new TypeAdapter<RealmList<RealmDoubleObject>>() {
#Override
public void write(JsonWriter out, RealmList<RealmDoubleObject> value) throws IOException {
// Ignore
}
#Override
public RealmList<RealmDoubleObject> read(JsonReader in) throws IOException {
RealmList<RealmDoubleObject> list = new RealmList<RealmDoubleObject>();
in.beginArray();
while (in.hasNext()) {
Double valor = in.nextDouble();
list.add(new RealmDoubleObject(valor));
}
in.endArray();
return list;
}
})
.create();
And then we have to put some other constructor method
public RealmDoubleObject(double v) {
this.value = v;
}
and this is all.
Thanks for the help #EpicPandaForce

Unmarshaller code using JAXB:
public RtSuperQuickMetadata unmarshallXml(final File metadataFile)
throws JAXBException, FileNotFoundException
{
RtSuperQuickMetadata rtSuperQuickMetadata = null;
try
{
JAXBContext jc = JAXBContext.newInstance(RtSuperQuickMetadata.class);
Unmarshaller um = jc.createUnmarshaller();
rtSuperQuickMetadata =
(RtSuperQuickMetadata) um.unmarshal(metadataFile);
}
catch (JAXBException e)
{
String msg = "Malformed XML supplied as Metadata" + " Msg " + e.getMessage();
LOG.error(msg, e);
throw new RuntimeException(msg, e);
}
return rtSuperQuickMetadata;
}

You have too many XmlRootElements, you generally want to use this with the top element only. What you want to do is label the children as XmlElement.
Remove the XmlRootElement annotation from all but your root element (i.e. RtSuperQuickMetadata), and label them with XmlElement in the class from which they will be loaded.
So, as an example, here is how your RtSuperQuickMetadata class should look:
#XmlRootElement(name = "contentFiles")
class RtSuperQuickMetadata
{
private List<RtSuperQuickMetadataItem> rtSuperQuickMetadataItems;
public RtSuperQuickMetadata()
{
rtSuperQuickMetadataItems = new ArrayList<RtSuperQuickMetadataItem>();
}
#XmlElement(name = "contentFile")
public List<RtSuperQuickMetadataItem> getRtSuperQuickMetadataItems()
{
return rtSuperQuickMetadataItems;
}
public void setRtSuperQuickMetadataItems(
List<RtSuperQuickMetadataItem> rtSuperQuickMetadataItems)
{
this.rtSuperQuickMetadataItems = rtSuperQuickMetadataItems;
}
}
Transfer this principle to alternateDocNumbers and citesAffected as well.
If you want to see an example of how the Unmarshaller thinks your XML is formatted based off your annotations, you can create your structure in code and use the Marshaller. Here is a quick and ugly example:
RtSuperQuickMetadata rtSuperQuickMetadata = new RtSuperQuickMetadata();
List<RtSuperQuickMetadataItem> rtSuperQuickMetadataItems = new ArrayList<RtSuperQuickMetadataItem>();
rtSuperQuickMetadata.setRtSuperQuickMetadataItems(rtSuperQuickMetadataItems);
RtSuperQuickMetadataItem item = new RtSuperQuickMetadataItem();
rtSuperQuickMetadataItems.add(item);
ArrayList<Cite> cites = new ArrayList<Cite>();
Cite cite = new Cite();
cite.setCiteStr("MyCite");
cites.add(cite);
item.setCitesAffected(cites);
Marshaller m = jaxbContext.createMarshaller();
m.setProperty(Marshaller.JAXB_FORMATTED_OUTPUT, true);
m.marshal(rtSuperQuickMetadata, System.out);
This will output the result to System.out. You can put this in a file instead, whatever suits your needs.

I have added this answer to address the follow up questions you posted as comments on the answer given by cklab.
I had another question. Why doesn't jaxb automatically allocate memory
for the lists contained in the object. Why do we need to assign memory
in a constructor for it ?
You do not need to, see below.
While unmarshalling these items the following isn't being saved into
the metadata object. 12 I
need to add another element for this to be generated ??
See mapping below.
