JUnit test for testing my API client is not working, “Error: Test Engine with ID 'junit-jupiter' failed to...












2















I am new at testing with Junit and using mockito. I have created a class for my client which is supposed to send requests to an API. I have also created a class to write a simple test. When i run the test i get errors in the console and i do not know how to solve them. I have tested the API that i am sending requests to by using Postman.
Here is my code for the Client:



import io.netty.handler.codec.http.HttpResponse;
import io.vertx.core.AsyncResult;
import io.vertx.core.buffer.Buffer;
import io.vertx.core.json.JsonObject;
import io.vertx.core.logging.Logger;
import io.vertx.core.logging.LoggerFactory;
import io.vertx.ext.web.client.HttpRequest;
import io.vertx.ext.web.client.WebClient;

public class MyClient {

private WebClient webclient;
private String requestURL;
private static Logger logger = LoggerFactory.getLogger(MyClient.class);

public MyClient(WebClient webclient, String requestURL) {
this.webclient = webclient;
this.requestURL = requestURL;
}

public void invokeCore(JsonObject request, java.util.function.Consumer<JsonObject> func){
webclient.post(requestURL)
.putHeader("content-type", "application/json")
.sendJson(request, ar -> {
if (ar.succeeded()) {
logger.info("succeeded: " + ar.succeeded());
logger.info("statusCode: " + ar.result().statusCode());
logger.info("body: " + ar.result().body());
logger.info("headers: " + ar.result().headers());
JsonObject response = new JsonObject();
// populate it
func.accept(response);
} else {
logger.info("Executed: " + ar.cause());
}
});
}
}


This is what i have written for the test class: I set up a mock WebClient and use it when creating a MyClient instance to send a request to the API.

doAnswer(new Answer() {

@Override
public Object answer(InvocationOnMock invocation) throws Throwable {
// TODO Auto-generated method stub
java.util.function.Consumer func = invocation.getArgument(1);
func.accept(mockResponse);
return null;
}

}).when(mockRequest).sendJson(any(), any());
return mockWebClient;
}

@Test
@DisplayName("Test response from client")
public void test() {
//request being sent

//expected response
JsonObject response = new JsonObject().put("clientToken", "11oije311").put("clientID", "123ID");

//test setup
MyClient coreClient = new MyClient(createMockWebClient(new JsonObject()), "http://localhost:8080/core");

//test steps
coreClient.invokeCore(request, resp -> {
assertEquals(resp.getString("clientToken"), response.getString("clientToken"));
//end.finished();
});
}
}


Here is the error that appears in the console when i try to run the test:

  • I ran this in IntelJ IDEA and works fine. Maybe the issue is with how the test is executed in eclips

  • It works? Well that is good news! Now, just have to get it to work for me, not sure any other way to execute it in eclipse though. Any ideas?

  • Yea it works(but test case fails as I dont have the mockResponse ). Actually I dont know how eclips executes junit test cases. But note that NoClassDefNoFoundError, the class ComparisionFailure.java is only available in Junit 4, and you are using Junit 5.

I am new at testing with Junit and using mockito. I have created a class for my client which is supposed to send requests to an API. I have also created a class to write a simple test. When i run the test i get errors in the console and i do not know how to solve them. I have tested the API that i am sending requests to by using Postman.
Here is my code for the Client:



import io.netty.handler.codec.http.HttpResponse;
import io.vertx.core.AsyncResult;
import io.vertx.core.buffer.Buffer;
import io.vertx.core.json.JsonObject;
import io.vertx.core.logging.Logger;
import io.vertx.core.logging.LoggerFactory;
import io.vertx.ext.web.client.HttpRequest;
import io.vertx.ext.web.client.WebClient;

public class MyClient {

private WebClient webclient;
private String requestURL;
private static Logger logger = LoggerFactory.getLogger(MyClient.class);

public MyClient(WebClient webclient, String requestURL) {
this.webclient = webclient;
this.requestURL = requestURL;
}

public void invokeCore(JsonObject request, java.util.function.Consumer<JsonObject> func){
webclient.post(requestURL)
.putHeader("content-type", "application/json")
.sendJson(request, ar -> {
if (ar.succeeded()) {
logger.info("succeeded: " + ar.succeeded());
logger.info("statusCode: " + ar.result().statusCode());
logger.info("body: " + ar.result().body());
logger.info("headers: " + ar.result().headers());
JsonObject response = new JsonObject();
// populate it
func.accept(response);
} else {
logger.info("Executed: " + ar.cause());
}
});
}
}


This is what i have written for the test class: I set up a mock WebClient and use it when creating a MyClient instance to send a request to the API.



import static org.junit.jupiter.api.Assertions.assertEquals;
import static org.mockito.ArgumentMatchers.any;
import static org.mockito.Mockito.mock;
import static org.mockito.Mockito.*;
import java.awt.List;
import javax.xml.ws.Response;

import org.junit.jupiter.api.Test;
import org.junit.jupiter.api.extension.ExtendWith;
import org.mockito.invocation.InvocationOnMock;
import org.mockito.stubbing.Answer;
import io.netty.util.concurrent.Future;
import io.vertx.core.Vertx;
import io.vertx.core.buffer.Buffer;
import io.vertx.core.json.JsonObject;
import io.vertx.ext.web.client.HttpRequest;
import io.vertx.ext.web.client.WebClient;
import io.vertx.junit5.VertxExtension;
import io.vertx.junit5.VertxTestContext;

@ExtendWith(VertxExtension.class)
public class MyClientTest {

private MyClient client;

//set up WebClient
private WebClient createMockWebClient(JsonObject mockResponse) {
WebClient mockWebClient = mock(WebClient.class);
HttpRequest<Buffer> mockRequest = mock(HttpRequest.class);

when(mockWebClient.post(any())).thenReturn(mockRequest);
when(mockRequest.putHeader(any(), any())).thenReturn(mockRequest);
doAnswer(new Answer() {

@Override
public Object answer(InvocationOnMock invocation) throws Throwable {
// TODO Auto-generated method stub
java.util.function.Consumer func = invocation.getArgument(1);
func.accept(mockResponse);
return null;
}

}).when(mockRequest).sendJson(any(), any());
return mockWebClient;
}

@Test
@DisplayName("Test response from client")
public void test() {
//request being sent
JsonObject request = new JsonObject().put("SSN", "123456789").put("Address", "123 main st").put("zip", "08888").put("dob", "012387");

//expected response
JsonObject response = new JsonObject().put("clientToken", "11oije311").put("clientID", "123ID");

//test setup
MyClient coreClient = new MyClient(createMockWebClient(new JsonObject()), "http://localhost:8080/core");

//test steps
coreClient.invokeCore(request, resp -> {
assertEquals(resp.getString("clientToken"), response.getString("clientToken"));
//end.finished();
});
}
}


Here is the error that appears in the console when i try to run the test:

  • I ran this in IntelJ IDEA and works fine. Maybe the issue is with how the test is executed in eclips

  • It works? Well that is good news! Now, just have to get it to work for me, not sure any other way to execute it in eclipse though. Any ideas?

  • Yea it works(but test case fails as I dont have the mockResponse ). Actually I dont know how eclips executes junit test cases. But note that NoClassDefNoFoundError, the class ComparisionFailure.java is only available in Junit 4, and you are using Junit 5.

Check if mockito supports junit5 or maybe one of mockito or junit5 versions are outdated. Today i've lost a lot of time with a newet version of mockito according to the junit4 ones. Junit5 5.3.2 is the most recent, you are using 5.1.0.
Other option is you must add another dependencie.
