I have a Spring Boot + Camel project and want to test routes without using Kafka (which is the main bus). In order to have ligther tests I want to use only "direct" endpoints in tests.
#CamelSpringBootTest
#TestPropertySource(
properties = {
"camel.component.kafka.enabled=false"
}
)
#ContextConfiguration(
classes = Application.class
)
#MockEndpoints
final class TopicRouteBuilderTest {
#Autowired
private CamelContext context;
#Test
void runsRoute() {
...
}
}
But Camel still tries to initialize Kafka component and fails with the following message:
org.apache.camel.FailedToStartRouteException: Failed to start route route1 because of null

Is there a way to disable Kafka component completely?
You may need to add:
#UseAdviceWith
#SpringBootTest("spring.autoconfigure.exclude=org.springframework.boot.autoconfigure.kafka.KafkaAutoConfiguration")
in addition to:
#TestPropertySource(properties = "camel.component.kafka.enabled=false")
You will then need to remove any Kafka routes you've not mocked with something like:
AdviceWith.adviceWith(context, routeId, routeBuilder ->
routeBuilder.weaveByToUri("kafka:*").remove());

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));
}
EDIT following is the latest stacktrace which I'm getting:

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 have a SpringBoot SOAP WebService annotated with #RolesAllowed("SOME_ROLE"). The production code works correct, i.e. if I send a SOAP-Request with the header "Authorization: Basic ENCODED_USERNAME_PASSWORD", service pass, if this header is not provided, then 401 comes back.
The problem is with Integration Tests. Below is a code snippet:
#SpringBootTest(webEnvironment = SpringBootTest.WebEnvironment.RANDOM_PORT)
#ActiveProfiles("test")
#TestMethodOrder(MethodOrderer.OrderAnnotation.class)
#AutoConfigureWebTestClient
class MyApplicationIT {
#LocalServerPort
int randomServerPort;
#Test
void find() {
MyServicePortType port = getServicePort();
port.findResult();
}
private MyServicePortType getServicePort() {
final URL wsdlUrl;
try {
wsdlUrl = new URL("http", "localhost", randomServerPort, "wsdl/data.wsdl");
} catch (MalformedURLException e) {
throw new RuntimeException(e);
}
final MyService service = new MyService (wsdlUrl);
final QName portName = new QName("some_url", "My_PortTypeSoap11");
final MyServicePortType port = service.getPort(portName, MyServicePortType .class);
final Map<String, List<Object>> headers = new HashMap<>();
headers.put("Authorization", singletonList("Basic " + "ENCODED_USERNAME_PASSWORD"));
}
final Map<String, Object> requestContext = ((BindingProvider) port).getRequestContext();
requestContext.put(MessageContext.HTTP_REQUEST_HEADERS, headers);
// requestContext.put(BindingProvider.USERNAME_PROPERTY, "manager_user_and_test_user");
// requestContext.put(BindingProvider.PASSWORD_PROPERTY, "secret");
return port;
}
}
I have tried out both combinations - to put Authorization header MessageContext.HTTP_REQUEST_HEADERS and to put properties BindingProvider.USERNAME_PROPERTY and BindingProvider.PASSWORD_PROPERTY.
Both does not work. I always get the following 401 error message.
Once again - only by running Integration Tests.
Is this related to wrong client (port) configuration or something to do with ldap schema used for tests?

I want to test my saveEmployee method but the problem is during #InjectMocks, constructor of EmployeeBase class is called and fetchEmployees() method is called. This method aim is to fetch data from database to employees List in the EmployeeBase class. The problem is this method use fields from Constants class and I am getting following result when I run the program. How to mock it properly?
class EmployeeBaseTest {
#InjectMocks
private EmployeeBase employeeBase;
#Mock
private Response response;
#BeforeEach
void beforeEach() {
MockitoAnnotations.openMocks(this);
}
#Test
void saveEmployeeTest() {
// given
Employee employee = new Employee();
// when
when(fetchEmployees()).thenReturn(Collections.emptyList());
employeeBase.saveEmployee(employee);
// then
assertEquals("TEST", response.getBody());
}
}
public class EmployeeBase {
private final Response response;
private final List<Employee> employees;
public EmployeeBase(Response response) {
this.response = response;
employees = fetchEmployees();
}
public void saveEmployee(Employee employee) {
//...
}
}
public final class EmployeeUtils {
private EmployeeUtils() {}
public static List<Employee> fetchEmployees() {
ScanRequest scanRequest = new ScanRequest().withTableName(EMPLOYEES);
ScanResult scanResult = AMAZON_DYNAMO_DB.scan(scanRequest);
List<Employee> employees = new ArrayList<>();
for (Map<String, AttributeValue> employee : scanResult.getItems()){
employees.add(parseEmployee(employee));
}
return employees;
}
}
public final class Constants {
protected static final String EMPLOYEES = "EMPLOYEES";
protected static final AmazonDynamoDB AMAZON_DYNAMO_DB = AmazonDynamoDBClientBuilder.defaultClient();
private Constants() {}
}

Code:
class EmployeeBaseTest {
#Test
void saveEmployeeTest() {
try (MockedStatic<EmployeeUtils> mockedScope = Mockito.mockStatic(EmployeeUtils.class)) {
mockedScope.when(EmployeeUtils::fetchEmployees).thenReturn(Collections.emptyList());
var response = Mockito.mock(Response.class);
var employeeBase = new EmployeeBase(response);
employeeBase.saveEmployee(new Employee());
assertEquals("TEST", response.getBody());
}
}
}
You can use Mockito#mockStatic for this.
try (MockedStatic<EmployeeUtils> mockedScope = Mockito.mockStatic(EmployeeUtils.class)) {
mockedScope.when(EmployeeUtils::fetchEmployees).thenReturn(emptyList());
// rest of your test
}
You invoke static EmployeeUtils.fetchEmployees in EmployeeBase constructor.
If you want yo have EmployeeUtils.fetchEmployees stubbed when the constructor is being run, you need to run it in scope of Mockito.mockStatic block.
class EmployeeUtilsTest {
#Test
void saveEmployeeTest() {
try (MockedStatic<EmployeeUtils> mockedScope = Mockito.mockStatic(EmployeeUtils.class)) {
mockedScope.when(EmployeeUtils::fetchEmployees).thenReturn(Collections.emptyList());
var response = Mockito.mock(Response.class);
var employeeBase = new EmployeeBase(response);
}
}
}
In particular, if you initialize the employeeBase field in the #BeforeEach method, the constructor is not run in scope of mockedStatic block.
More generally, there are a few patterns in your code which make it harder to test:
static utility classes
calling external services from constructor of the object
Rethink the design before going fancy with mockStatic
My tests for this CRUD operation in Spring Boot continue to fail where I get "java.util.NoSuchElementException: No Value Present" I understand that testCreateDemographic is creating a record, however, testFindDemographicsById is not able to find the newly created record because it is using "1L" in findById(1L) to find a record. How do I get the correct new related record Id to place in findById() argument?
package com.lizardkinghotel.demographic;
import org.junit.jupiter.api.Test;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.boot.test.context.SpringBootTest;
import org.springframework.test.context.junit4.SpringRunner;
import com.lizardkinghotel.demographic.entities.DemographicEntity;
import com.lizardkinghotel.demographic.repos.DemographicRepository;
#SpringBootTest
class DemographicAppApplicationTests {
#Autowired
private DemographicRepository demoRepo;
#Test
public void testCreateDemographic() {
DemographicEntity demoEntity = new DemographicEntity();
//demoEntity.setId(1L);
demoEntity.setAge("39–47");
demoEntity.setChildren(2);
demoEntity.setCity("san jose");;
demoEntity.setCountry("costa rica");
demoEntity.setEducation("bacherlors degree");
demoEntity.setEmail("test#test.com");
demoEntity.setEmployment("yes");
demoEntity.setGender("male");
demoEntity.setGuestAmount(2);
demoEntity.setHearAbout("google search");
demoRepo.save(demoEntity);
}
#Test
public void testFindDemographicsById() {
DemographicEntity demoEntity = demoRepo.findById(1L).get();
}
//testing updating a record
#Test
public void testUpdateDemo() {
DemographicEntity demoEntity = demoRepo.findById(1L).get();
demoRepo.save(demoEntity);
}
#Test
public void testDeleteDemo() {
DemographicEntity demoEntity = demoRepo.findById(1L).get();
demoRepo.delete(demoEntity);
}
}

JUnit test should not depend on the other. Which means change your findById test to something like this:
#Test
public void testFindDemographicsById() {
DemographicEntity demoEntity = new DemographicEntity();
demoEntity.setAge("39–47");
demoEntity.setChildren(2);
demoEntity.setCity("san jose");;
demoEntity.setCountry("costa rica");
demoEntity.setEducation("bacherlors degree");
demoEntity.setEmail("test#test.com");
demoEntity.setEmployment("yes");
demoEntity.setGender("male");
demoEntity.setGuestAmount(2);
demoEntity.setHearAbout("google search");
DemographicEntity saved = demoRepo.save(demoEntity);
DemographicEntity demoEntity = demoRepo.findById(saved.getId()).get();
}
