UnexpectedCharacter's questions

I am trying to run a test. Where I try to mock a specific class. So that you understand the scenario we have a class Controller, Service, Dao, and finally the class in question that I am trying to mock.

@RunWith(SpringRunner.class)
@SpringBootTest(classes = { Main.class }, webEnvironment = WebEnvironment.DEFINED_PORT)
@ActiveProfiles("api")
public class UnitTest {

    @Rule
    public MockitoRule rule = MockitoJUnit.rule();

    private static final String API_URL = "http://test:6536/api/url"; 

    private static final String DATA_CONSTANT = "{\"nationality\":\"Camboya\"}";

    private static final Bean BEAN = BeanBuilder.getInstance().withId("").withData(DATA_CONSTANT).build();

    @Mock
    private HttpIntegrator httpIntegrator; //La clase que despues de surcar controlador, servicio y dao hace la llamada y quiero moquear

    @Autowired
    private ApiController controller; //La clase la cual quiero que coja del contexto de spring para asi poder alcanzar todas las clases que son inyectadas(tales como servicio, dao etc)


    @Test
    public void post_Ok() throws Exception {
    final HttpResponseBean httpResponse= HttpResponseBean.newInstance(HttpStatus.OK.ordinal(), "OK", BEAN.toString().getBytes());

    Mockito
        .doReturn(httpResponse)
        .when(this.httpIntegrator).postRequest(Matchers.any(String.class), Matchers.any(Map.class), Matchers.any(String.class));

    final ResponseEntity<Response> response = controller.post(DATA_CONSTANT);

    Mockito.verify(this.httpIntegrator).postRequest(API_URL, generateHttpRequestHeaders(), DATA_CONSTANT); //Excepcion
    }
}

I load the SpringRunner runner so I can take advantage of the classes it injects into the context when the app starts. Since I'm not interested in mocking all classes. I'm just trying to sniff HttpIntegrator. But of course to be able to mock I need the mockito runner, so I have added the rule to be able to add it.

I mock HttpIntegrator and set the behavior I want when it gets called. Debugging I'm already annoyed that by putting a breakpoint in the method I call from HttpIntegrator I can perform the debug (I say I'm annoyed because I thought mocks couldn't be debugged, but I'm probably wrong).

The issue is that when I check if it has made the call I get the following exception and that is what really assures me that it does not work.

Wanted but not invoked

What I can be doing wrong? Thanks in advance.

UPDATE

The response I get is not the same as the one I apply in doReturn(). Since I have defined the response of the mock with the following:

final HttpResponseBean httpResponse= HttpResponseBean.newInstance(HttpStatus.OK.ordinal(), "OK", BEAN.toString().getBytes());

But what it returns to me does not correspond to that. It is similar, but the BEAN.toString() that the mocked method returns to me is the one that returns me as if I made the call without having established the response that the mock should have. So I have established a series of matchers to the matcher and the error that returns me is the following:

Mockito.verify(this.httpIntegrator).postRequest(API_URL, Matchers.anyObject(), Matchers.anyString());

invalid use of argument matchers 3 matchers expected 2 recorded

I am currently looking for the cause

In an API when making a GET call, I am able to convert the response into its representation in a java object.

{
  "Id": "3-4779-841c-08f88e1d3889",
  "Data": "{'name':'nombre','city':'ciudad'}"
}

final HttpResponseBean httpResponseBean = this.httpIntegrator.getRequest(
                MessageFormat.format(
                    Dao.URL_PATTERN
                    , this.Scheme
                    , this.Url
                    , this.Port
                    , Dao.CONTEXT_PATH));

        final byte[] payload = httpResponseBean.getPayload();
        return mapper.readValue(payload, Bean.class);

This works perfectly but now I have to handle the response I get from a GET. But this time instead of managing to return a single value, I get the entire list of values. If I am able to map an object how could I map a response which I have an array of those objects in JSON format

[
        {
            "Id": "3-4779-841c-08f88e1d3889",
            "Data": "{'name':'nombre','city':'ciudad'}"
        }, 
        {
            "Id": "3-4779-841c-98f28e1d3689",
            "Data": "{'name':'nombre','city':'ciudad'}"
        },
        {
            "Id": "3-0729-891c-08f48s1d3889",
            "Data": "{'name':'nombre','city':'ciudad'}"
        }, 
]

I have a function which has two statements that are executed asynchronously.

const returnedPackage = await getAssetRegistry('es.test.Asset')
        .then(function (assetRegistry) {
            return assetRegistry.add(package);
    });

await setEnclosingAsset(recoveredVals, assetInfoObj['assetId']);

return returnedPackage;

The first lambda performs the save but without finishing, the second statement is executed. In the second sentence, with the identifier. I perform a search for the value that is being saved in the statement above. And I say saving because it returns an exception saying that no value with that identifier has been found. So I imagine that both are executed in parallel.

I thought that maybe I was doing the save wrong but if I comment the line of the await setEnclosingAsset()...... The save does it correctly for me.

Any suggestions to solve this execution flow error?

EDIT

I tried the following but the error persists

await getAssetRegistry('es.test.Asset')
    .then(function (assetRegistry) {
        newPackage = assetRegistry.add(package);
    })
    .then(function () {
        setEnclosingAsset(recoveredVals, assetInfoObj['assetId']);
    });

Well I have the following JSON:

{
  "creatorId": "#1",
  "data": {
            "id": "10",
            "creator": "#1"
        },
  "subs": ["1"]
}

But the content of data must not be an object. But an object in string format.

{
  "creatorId": "#1",
  "data": "{
              \"id\": \"10\",
              \"creator\": \"#1\"
            }",
  "subs": ["1"]
}

All this is because my intention is to collect the data field from the JSON and convert it to a js object.

const dataObj = JSON.parse(recoverJson.data);

And of course the simplest thing would be to pass the object directly to it and not have to collect the string and so on. But it is an API requirement that what arrives is a string.

How could I assemble the JSON with a "strigified" object

Originally I had a class with a lambda function in a java class.

        final Map<String, UserBean> users = persons.entrySet().stream()
            .filter(entry -> !entry.getValue().getIsActive().booleanValue())
            .collect(Collectors.toMap(
                entry -> entry.getKey()
                , entry -> entry.getValue()));

But sonar gave me a suggestion: Lambdas should be replaced with method references

So I started to output to external methods. I started by adding to the same class where the lambda was, a function that returned the key. And update the lambda as follows:

        final Map<String, UserBean> users = persons.entrySet().stream()
            .filter(entry -> !entry.getValue().getIsActive().booleanValue())
            .collect(Collectors.toMap(
                    this::<String>getEntryKey
                    , entry -> entry.getValue()));

This worked perfectly for me and the sonar suggestion was only marked on the arrow that was on the bottom line of the statement that I modified. The issue is that I realized that this warning was repeated in many places in the code. So I started to make a utility class so as not to repeat code.

The utility class I have has two methods to get the keys and values ​​of a map:

public class LambdaUtils {

private static final LambdaUtils INSTANCE = new LambdaUtils();

public static LambdaUtils getInstance() {
    return LambdaUtils.INSTANCE;
}

public <K> K getEntryKey(Entry<K, ?> entry) {
    return entry.getKey();
}

public <V> V getEntryValue(Entry<?, V> entry) {
    return entry.getValue();
}
}

The problem is that now I don't know how to add that call to the utility class methods inside the lambda.

    final Map<String, UserBean> users = persons.entrySet().stream()
            .filter(entry -> !entry.getValue().getIsActive().booleanValue())
            .collect(Collectors.toMap(
                    this::LambdaUtils.getInstance().getEntryKey() //ERROR
                    , entry -> entry.getValue()));

How can I make the call to that external method inside a lambda?

I have a class that I call from another class:

public class caller {
    @Test
    public void test() throws Exception {
        Calle.getInstance().run();
    }
}

---------------------------------------------------------------------------

@RunWith(SpringRunner.class)
@SpringBootTest(classes = { Swagger2SpringBoot.class }, webEnvironment = WebEnvironment.DEFINED_PORT)
@ActiveProfiles("api")
public final class Calle extends AbstractTest {

    @Autowired
    private UserApi userApi;

    private static final Calle INSTANCE = new Calle();

    public static Calle getInstance() {
        return Calle.INSTANCE;
    }

    private Calle() {
    }

    public void run() throws Exception {
        final User usr1 = this.createUser(this.userApi);
    }
}

 MAIN

@ComponentScan(
    basePackages = {
         "es.comp.api",
         "es.comp.api.controller",
         "es.comp.api.configuration"
    }

The UserApi class is added in the main ("es.comp.api.controller",)

Apparently and from what I could read. When a class is called in a singleton. Spring does not load dependencies that are loaded with the @Autowired tag. So when doing the this.createUser(this.userApi) it gives me a NullPointerException.

How could I solve this error? All the best

I have a string like this:

var cadena = '<form name="name" th:action=" 'ERROR' ">';

I have a single quote inside the string and it is what limits the beginning and the end, how can I do to include the escape characters as part of the string?

All the best.

I make an Ajax request to a web service and it returns an object.

    $(document).ready(function () {
    $.ajax({
        url: "https://www.alphavantage.co/query?function=TIME_SERIES_INTRADAY&symbol=MSFT&interval=1min&apikey=*******"
    }).then(function (data) {
        console.log(JSON.stringify(data));
    });
});

In the console I see the object that has a structure similar to the following:

{"Meta Data":{"1. Information":"Intraday (1min) prices and volumes","2. Symbol":"MSFT","3. Last Refreshed":"2018-05-30 16:00:00","4. Interval":"1min","5. Output Size":"Compact","6. Time Zone":"US/Eastern"},"Time Series (1min)":{"2018-05-30 16:00:00":{"1. open":"99.0000","2. high":"99.0500","3. low":"98.9100","4. close":"98.9500","5. volume":"2233252"}, ......

The issue is that I don't know how to access, for example, the value of the field open":"99.0000"

What should I do?

I have this String:

[
    {'lat':43.4627,'lng':-3.79636,'description':'a'}, 
    {'lat':43.4476,'lng':-3.82948,'description':'b'}, 
    {'lat':43.4228,'lng':-3.82391,'description':'c'}
]

And when I try to validate it here it gives me this error:

SyntaxError: JSON.parse: expected property name or '}' at line 1 
column 2 of the JSON data

Can anyone tell me what's wrong with my String?

I have a List of an Object.

public class BusStop {

    private String description;

    private float lat;

    private float lng;

    //getter and setter

}

Of which I try to put all its content inside a variable of type String.

I have tried this:

StringBuilder aux = new StringBuilder();
busStop.forEach(aux::append);

return aux.toString();

But the response I get is not the desired one.

[email protected]@15820f4bes.yo.app.model.BusStop@2022ad11

And this is just what I want to achieve

[{"lat":43.482243622643026,"lng":-3.7942432892720035,"description":"1"},{"lat":43.47775946266253,"lng":-3.8052296173970035,"description":"2"},{"lat ":43.474520695703184,"lng":-3.822567416469269,"description":"3"}]

I am trying to create a new array for each return of a for.

var route = [];

for (var i = 0; i < 5; i++) {
  route[i].push(result.routes[0].overview_path[i].lat());
  route[i].push(result.routes[0].overview_path[i].lng());

  console.log(route[i]);

}

But the console tells me that it isundefined

I have this array that I add objects to:

waypts.push({location: location.lat() + "," + location.lng()});

How can I get the literal value it saves? With Object.valueand valueOfdoes not do what I pretend

I am preparing a regular expression:

[a-zA-Z0-9._-]{20}

So far I'm dealing with the pre-"@" part of an email and I'm trying to do something like this:

[a-zA-Z0-9._-]{"*"-20}

Where "*" appears I try to put that it does not have a minimum size, but a maximum

How could I mount the expression?

The idea is to use it later to do this:
Email in multi-character format (letters, numbers, periods, or underscores, 20 maximum) followed by at sign, letters (20 maximum), period (1), and 2 or 3 letters .

I have a dialog box that shows a text and two buttons. How can I make it so that when I click on the accept button it reloads the html file it is in or can I reference an html file so that it loads?

var cuadroDialogo = confirm("Que mente mas privilegiada tienes compañer@\n¿Quieres mas?");
                if(cuadroDialogo == true) alert("Me alegro !!");
                else alert("Pues es una pena !!");

I have a file that contains the object I want to manipulate. I think two for example. But when in the showArrayOrdenado() function I apply the sort() to order it, since it is about objects and not literals. don't order me My idea is that they are ordered by the name parameter of each object that makes up the array. It's possible?

function Sandskill(nom, edad, especialidad, comp) {
  this.nombre = nom;
  this.edad = edad;
  if (especialidad == 1 || especialidad == 2 || especialidad == 3) {
    if (especialidad == 1)
      this.especialidad = "sistemas";
    if (especialidad == 2)
      this.especialidad = "web";
    if (especialidad == 3)
      this.especialidad = "multiplataforma";
  } else {
    this.especialidad = null;
  }
  this.comp = comp;

  //GETTER
  this.getNom = function() {
    return this.nombre;
  }
  this.getEdad = function() {
    return this.edad;
  }
  this.getEspecialidad = function() {
    return this.especialidad;
  }
  this.getComp = function() {
    return this.comp;
  }
}

var s1 = new Sandskill("Pepe", "22", "1");
var s2 = new Sandskill("Juan", "22", "2", s1);

function mostrarArrayOrdenado() {
  sandskillArray.sort();
  for (i = 0; i < sandskillArray.length; i++) {
    alert(sandskillArray[i].getNom() + " * " + sandskillArray[i].getEdad() + " * " + sandskillArray[i].getEspecialidad() + " * ")
  }
}

How can I get the number of uppercase and lowercase vowels in a variable in JavaScript.

        var person = new Object();
        person = prompt("Introduce tus datos");

        //Numero de vocales
        var numVocales;

        for (i = 0; i < 10; i++) { 

            var vocal;

            if (i = 0){
                vocal = "a";
            }
            else if (i = 1){
                vocal = "e";
            }
            else if (i = 2){
                vocal = "i";
            }
            else if (i = 3){
                vocal = "o";
            }
            else if (i = 4){
                vocal = "u";
            }
            else if (i = 5){
                vocal = "A";
            }
            else if (i = 6){
                vocal = "E";
            }
            else if (i = 7){
                vocal = "I";
            }
            else if (i = 8){
                vocal = "O";
            }
            else if (i = 9){
                vocal = "U";
            }

            var aux = person.indexOf(vocal);

            if(aux != -1){
                numVocales++;
            }

        }


        alert(numVocales);

I can't display the information in the alert, it may be that the for is wrong. Also, I don't know if using indexOf() will get me the first matching letter. I mean, if I have ana, would using indexOf() return one or two?

What are the differences when using single or double quotes for text strings in JavaScript?

 var dam = 'Desarrollo de aplicaciones multiplataforma';
