I'm using Javalin 4 and Mockito 4, and I want to test a simple controller method.
I was reading a tutorial in here : https://javalin.io/tutorials/testing
here is my controller :
package mhndev.controller;
import io.javalin.http.Context;
public final class CakeController
{
private CakeController() {}
static String[] cakes = {"Cheese", "Chocolate", "Carrot", "Banana"};
public static void getOneCake(Context ctx) {
for(String cake: cakes) {
if(cake.equals(ctx.pathParam("cake"))) {
ctx.result(cake);
return;
}
}
ctx.result("cake was not found!");
}
}
And this is my very simple test:
package mhndev;
import io.javalin.http.Context;
import mhndev.controller.CakeController;
import org.junit.jupiter.api.Test;
import static org.mockito.Mockito.*;
public class CakeControllerTest {
private final Context ctx = mock(Context.class);
#Test
public void GET_apple_cakes() {
when(ctx.pathParam("cake")).thenReturn("Banana");
CakeController.getOneCake(ctx);
verify(ctx, times(1)).pathParam("Banana");
}
}
And I received this error upon running the test :
java.lang.NullPointerException: Parameter specified as non-null is null: method io.javalin.http.util.ContextUtil.pathParamOrThrow, parameter pathParams
at io.javalin.http.util.ContextUtil.pathParamOrThrow(ContextUtil.kt)

It's like Context.pathParam method is really getting called, using mockito and mocking the context object shouldn't create a new object and not calling the real method from real object? Why this happens and How should I test?

I am doing some task execution using the spring ThreadPoolTaskExecutor class using the submitListenable(Callable<T> task) method.
When I call cancel(true) on the listenablefuture returned by the submit method I get a cancellation exception and I cant understand why. Below is a sample code snippet
Can someone explain to my why?
ThreadPoolTaskExecutor ex = new ThreadPoolTaskExecutor();
ex.setCorePoolSize(2);
ex.initialize();
ListenableFuture<String> lis = ex.submitListenable(()-> {
try {
Thread.sleep(10000);
return "done";
}
catch (InterruptedException e) {
System.out.println("interrpted");
return "not done";
}
});
CompletableFuture<String> fut = lis.completable();
fut.exceptionallyAsync(th-> {
if(th instanceof CancellationException) {
System.out.println("cancelled");
return "cancelled";
}
return "some exception occurred";
});
lis.cancel(true);//<-- cancellation exception thrown here
fut.get(1, TimeUnit.SECONDS);

Eclipse exception stacktrace:
lis.cancel(true); throws CancellationException and puts it in CompletableFuture(fut). When fut.get(1, TimeUnit.SECONDS); requests for a canceled transaction, it will (re-)thrown this error.
CompletableFuture content in fut.get(1, TimeUnit.SECONDS); line:
E.g: You can try a method where you will not call a get request if it is canceled:
if (!lis.isCancelled()) {
fut.get(1, TimeUnit.SECONDS);
}
This is an example, you will need different approaches according to your need, you can do research.
I'm trying to write unit tests for Java based gRPC client where the server is remote.
All the examples I've seen use a local gRPC server for writing client unit test cases.
How can I mock the server so my client unit test cases are able to run.
public class MyProtoClient {
private final ManagedChannel channel;
public MyProtoClient() {
this(ManagedChannelBuilder.forAddress("{remote_url}", remote_port)
.usePlaintext()
.build());
}
MyProtoClient(ManagedChannel channel) {
this.channel = channel;
}
public Boolean getResult(int a, int b) {
MyProtoGrpc.MyProtoBlockingStub stub = MyProtoGrpc.newBlockingStub(this.channel);
MyProtoResponse response = stub.myProtoRequest(ReqPayload.newBuilder()
.setNum1(a)
.setNum2(b)
.build());
this.channel.shutdown();
return response.getSum();
}
}
Here is the code of my test class. But it throws an error saying it's trying to connect to the remote_url.
The below code throws java.lang.NullPointerException.
public class MyProtoClientTest {
#InjectMocks
MyProtoClient myProtoClient;
#Mock
private ManagedChannel managedChannel;
#BeforeEach
void setUp() throws Exception {
myProtoClient = new MyProtoClient(managedChannel);
}
#Test
void getResult() {
int a = 1;
int b = 2;
MyProtoGrpc.MyProtoGrpcBlockingStub mockMyProtoBlockingStub =
MyProtoGrpc.newBlockingStub(managedChannel);
MyProtoResponse mockResponse = mock(MyProtoResponse.class);
ReqPayload req = ReqPayload.newBuilder()
.setNum1(a)
.setNum2(b)
.build());
when(mockMyProtoBlockingStub.myProtoRequest(req)).thenReturn(mockResponse);
assertTrue(myProto.getResult(a, b));
}

For cases like this, I tend to add a second, package private constructor:
public class MyProtoClient {
private final ManagedChannel channel;
public MyProtoClient() {
this(ManagedChannelBuilder.forAddress("{remote_url}", remote_port)
.usePlaintext()
.build());
}
MyProtoClient(ManagedChannel channel) {
this.channel = channel;
}
...
This allows you to call the second constructor with the mocked ManagedChannel. I prefer not to use #InjectMocks at all for cases like this, and create the object myself:
#BeforeEach
void setUp() throws Exception {
// managedChannel can still be annotated with #Mock
myProtoClient = new MyProtoClient(managedChannel);
}
Note that the stub is still not mocked, but its backing channel is. You may have to do some more low-level mocking to get your test to work.
I'm not an expert with gRPC, but my guess is the following:
In your test you're using a mocked ManagedChannel, but at some point gRPC must be trying to instantiate a ClientCall object from it.
As it's a basic mock, it's simply returning null, which causes a java.lang.NullPointerException when gRPC is executing io.grpc.stub.ClientCalls.startCall(ClientCalls.java:341) (from your stacktrace)
I have 2 suggestions:
try using a non-mocked ManagedChannel in your tests, or mock the required methods to provide a non-null ClientCall to gRPC
try to adapt your tests to mimic the official gRPC example project (the client class / the test class)
I am getting the following error while mocking with mockito:
Method threw
'org.mockito.exceptions.misusing.UnfinishedStubbingException'
exception. Cannot evaluate
util.DocumentHelper$MockitoMock$1355901941.toString()
Here is the test:
#RunWith(SpringRunner.class)
#SpringBootTest
class EurLexHtmlToHtmlServiceTest {
#Mock
private DocumentHelper documentHelper;
#InjectMocks
private EurLexHtmlToHtmlService eurLexHtmlToHtml;
#Test
void urlToHtmlSetUpCorrectStyle() throws IOException {
private final String url = "https://someUrl.com/";
Map<String, String> params = ImmutableMap.of(
"url", url,
"hasOnlyOneSheet", "false",
"hasBorders", "false"
);
Mockito
.when(documentHelper.getDocument(anyString()))
.thenReturn(new Document("src/test/resources/eurlexTest.html"));
assertThat(eurLexHtmlToHtml.urlToHtml(params))
.hasContent("<style>test</style>");
}
}
DocumentHelper is a wrapper of Jsoup:
#Component
public class DocumentHelper {
public Document getDocument(String url) throws IOException {
return Jsoup.connect(url).get();
}
}
#Service
public class EurLexHtmlToHtmlService extends BaseHtmlToHtml {
final DocumentHelper documentHelper;
private static final String eurlex_URL = "someUrl";
public EurLexHtmlToHtmlService(DocumentHelper documentHelper) {
this.documentHelper = documentHelper;
}
#Override
public InputStream urlToHtml(Map<String, String> params) throws IOException {
Document document = documentHelper.getDocument(params.get("url"));
Element content = document.body();
return getInputStream(document, content, eurlex_URL);
}
public abstract class BaseHtmlToHtml implements HtmlToHtmlService {
#Autowired
HtmlLayout htmlLayout;
#Autowired
DocumentHelper documentHelper;
protected InputStream getInputStream(Document doc, Element content, String url) throws IOException {
Element cssLink = doc.select("link").last();
String cssHref = cssLink.attr("href").replace("./../../../../", "");
Document cssDoc = documentHelper.getDocument(url + cssHref);
Elements cssElements = cssDoc.getAllElements();
content.append("<style>" + cssElements.outerHtml() + "</style>");
ByteArrayOutputStream outputStream = new ByteArrayOutputStream();
outputStream.write(content.outerHtml().getBytes());
outputStream.close();
return new ByteArrayInputStream(outputStream.toByteArray());
}
I guess that the issue might come from the fact that the method getDocument() is called twice, but event though trying some workaround it did not help

I am trying to learn spring by doing it's quick guides, and when I was trying to follow this spring quick guide I have problems, even if I do everything as it's put there.
I have problems en the consuming Rest guide, but I thing there is a mistake in the http request link.
Here you can find the guide https://spring.io/guides/gs/consuming-rest/
In my com.example.consumingrest I have:
package com.example.consumingrest;
import org.slf4j.Logger;
import org.slf4j.LoggerFactory;
import org.springframework.boot.CommandLineRunner;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.boot.web.client.RestTemplateBuilder;
import org.springframework.context.annotation.Bean;
import org.springframework.web.client.RestTemplate;
#SpringBootApplication
public class ConsumingRestApplication {
private static final Logger log = LoggerFactory.getLogger(ConsumingRestApplication.class);
public static void main(String[] args) {
SpringApplication.run(ConsumingRestApplication.class, args);
}
#Bean
public RestTemplate restTemplate(RestTemplateBuilder builder) {
return builder.build();
}
#Bean
public CommandLineRunner run(RestTemplate restTemplate) throws Exception {
return args -> {
Quote quote = restTemplate.getForObject(
"https://gturnquist-quoters.cfapps.io/api/random", Quote.class);
log.info(quote.toString());
};
}
}
the file Value.java
package com.example.consumingrest;
import com.fasterxml.jackson.annotation.JsonIgnoreProperties;
#JsonIgnoreProperties(ignoreUnknown = true)
public class Value {
private Long id;
private String quote;
public Value() {
}
public Long getId() {
return this.id;
}
public String getQuote() {
return this.quote;
}
public void setId(Long id) {
this.id = id;
}
public void setQuote(String quote) {
this.quote = quote;
}
#Override
public String toString() {
return "Value{" +
"id=" + id +
", quote='" + quote + '\'' +
'}';
}
}
and the qoute.java:
package com.example.consumingrest;
import com.fasterxml.jackson.annotation.JsonIgnoreProperties;
#JsonIgnoreProperties(ignoreUnknown = true)
public class Quote {
private String type;
private Value value;
public Quote() {
}
public String getType() {
return type;
}
public void setType(String type) {
this.type = type;
}
public Value getValue() {
return value;
}
public void setValue(Value value) {
this.value = value;
}
#Override
public String toString() {
return "Quote{" +
"type='" + type + '\'' +
", value=" + value +
'}';
}
}

Your assumption is right. The request url is not found. When I tried navigating to the url mentioned, the browser itself throws a 404 not found error code. This is not an issue with your code.
I am not able to execute unit test on a service class for a Spring Boot based web application using JUnit 5 and Mockito.

It is explained in the exception message:
This exception may occur if matchers are combined with raw values:
//incorrect:
someMethod(anyObject(), "raw String");
When using matchers, all arguments have to be provided by matchers.
For example:
//correct:
someMethod(anyObject(), eq("String by matcher"));
Either avoid using matchers when calling the method of a mocked object, or use matchers for all arguments:
when(restTemplate.getForEntity(any(URI.class), eq(Account.class))).thenReturn(result);
