testing Page<> with BDDMockito.given spring - java

I have a JPA query like this:
Page<Journey> findByDriverId(Long UserId, Pageable pageable);
And this is what I wrote in Test method:
#Mock
private JourneyDao dao;
#InjectMock
private JourneyService journeyService;
List<Journey> journeys = new ArrayList<>();
for (int i=0; i<=1; i++) {
Journey journey = new Journey();
journey.setDriverId(1L);
journey.setUsername("mike");
journey.setJourneyId("100"+i);
journeys.add(journey);
}
Page<Journey> journeyPage = new PageImpl<>(journeys);
given(this.dao.findByDriverId(1L, PageRequest.of(0, 2))).willReturn(journeyPage);
ResponseDto responseDto = this.journeyService.getJourneyOfUser(1L, 0, 10);
And this is the service method, which I am trying to test.
public ResponseDto getJourneyOfUser(Long userId, int page, int length) throws Exception {
Page<Journey> journeyPage = this.dao.findByDriverId(userId,
PageRequest.of(page, length));
List<Journey> journeys = journeyPage.getContent();
// and then mapping this to the responseDto by filtering out some unnecessary content
}
When I run the test case, I get NullPointerException. Because when service method is called from test case method, and when the service executes the query, it gives null.
Why is it happening? And how can I write such test cases in future?
Stacktrace:
Line: 459 (JourneyService.java) - Page<Journey> journeyPage = this.dao.findByDriverId(userId,
PageRequest.of(page, length));
Line 77 (JourneyServiceTest.java) - ResponseDto responseDto = this.journeyService.getJourneyOfUser(1L, 0, 10);

Karate- Getting NoClassDefFoundError when running the Test Runner as Junit

I am getting the below error when i run the test runner class as a junit test.I am using Java 1.8 U212 ...and just trying to run a dummy Soap project...has anyone come across this error?
Below is the Test Runner class that i am using:
package APITest;
//#RunWith(Karate.class)
#KarateOptions(features = "classpath:/hicaps_go_blackbox_integration_tests-claims_business_tests/src/test/java/APITest/SoapTest.feature", tags = "#SoapTest")
public class SoapTestRunner {
#Test
public void testParallel() {
//List<String> paths = new ArrayList<>(); paths.add(System.getProperty("user.dir") + "/src/test/java/tests/");
//Results results = Runner.parallel(null, paths, 5, "target/surefire-reports");
Results results = Runner.parallel(getClass(), 2, "target/surefire-reports");
assertTrue(results.getErrorMessages(), results.getFailCount() == 0);
generateReport(results.getReportDir());
}
public void generateReport(String karateOutputPath) {
Collection<File> jsonFiles = FileUtils.listFiles(new File(karateOutputPath), new String[] { "json" }, true);
List<String> jsonPaths = new ArrayList(jsonFiles.size());
jsonFiles.forEach(file -> jsonPaths.add(file.getAbsolutePath()));
Configuration config = new Configuration(new File("target"), "Karate_POC-master");
ReportBuilder reportBuilder = new ReportBuilder(jsonPaths, config);
reportBuilder.generateReports();
}
}
Below is the error returned:

Null Pointer Exception, when Writing Junit/Mockito Test cases at Controller class for Oauth, JSON response

I'm relatively new to Testing in Mockito, and I'm trying to write few test cases for Controller level testing and I'm getting Null pointer Exception when I'm running the test case. I'm Injecting mocks at controller layer and mocking the service layer methods. Please let me know, the issue

I've resolved the issue:
Solution and Fix:
In my TestCase Code, I've replaced the below any(String.class):
Mockito.when(ssasService.grantToken(any(String.class),any(SecureString.class),any(String.class) )).thenReturn(resp);
final TokenActivationResponse response = controller.grantToken(any(String.class),any(String.class),any(String.class));
With (anyString()):
Mockito.when(ssasService.grantToken(anyString(),any(SecureString.class),anyString() )).thenReturn(resp);
final TokenActivationResponse response = controller.grantToken(anyString(),any(String.class),anyString());
One of these Links hepled: Mockito - Invalid use of argument matchers
Also, if you use argument matcher in mockito for one argument, make sure to use for all.

Mocking method in mockito returns a Null Pointer Exception?

I'm writing a test that calls a method from another service:
// Setup mocks
private GoalService goalService;
private Principal principal;
private Goal goal;
private SecurityService securityService;
#Before
public void setup() {
goalService = new GoalService();
principal = mock(Principal.class);
goal = mock(Goal.class);
securityService = mock(SecurityService.class, Mockito.RETURNS_DEEP_STUBS);
}
#Test
public void testRequesterOwnsGoalIsTrue() {
doReturn(1).when(securityService).getUserIdByPrincipal(principal);
when(goal.getUsersUserId()).thenReturn(1);
boolean userOwnsGoal = goalService.requesterOwnsGoal(principal, goal);
assertEquals(true, userOwnsGoal);
}
During debug, when I call securityService.getUserIdByPrincipal(principal) I get a NPE. I am not sure why. Ideally, what I want is for the method call to return 1, I don't care about testing those function internal in this unit test.
Actual Code
Boolean requesterOwnsGoal(Principal principal, Goal goal) {
Optional<Goal> optionalGoal = Optional.ofNullable(goal);
if (optionalGoal.isPresent()) {
return secService.getUserIdByPrincipal(principal) == optionalGoal.get().getUsersUserId();
}
throw new StandardUserException("Requesting user does not have access to goal");
}

It should be doReturn(1).when(securityService).getUserIdByPrincipal(any(principal)); to make it work.
Or
doReturn(1).when(securityService).getUserIdByPrincipal(any(Principal.class));
The code shown so far indicates that you are in fact creating a mock object. But you are not injecting that mock into your class under test!
Just creating mocks isn't sufficient. You have to ensure that they get used by the code you are testing!
Most likely that is your problem here, but as we still don't have a [mcve] we can't be sure.

Cannot handle expected exception in integration test

I cannot pass test notFoundFoo since I get NestedServletException excpetion instead of expected FooNotFoundException exception.
What I do wrong in my test?

NestedServletException wraps only the cause of the exception.
It is not your actual issue.
Its javadoc defines itself as :
Subclass of ServletException that properly handles a root cause in
terms of message and stacktrace, just like
NestedChecked/RuntimeException does.
Exceptions thrown in a rest controller have to be mapped to a http response. If you didn't it, Spring does that for you by throwing NestedServletException/NestedCheckedException according to the exception nature (checked or runtime).
A Java exception is not a http response.
You cannot let it be thrown as you did in a classic java code.
You have to convert it as something compatible with the http norms.
For Rest controllers you should use #ExceptionHandler and #ControllerAdvice.
#ControllerAdvice
public class RestResponseEntityExceptionHandler extends ResponseEntityExceptionHandler {
#ExceptionHandler(FooNotFoundException.class)
protected ResponseEntity<Object> handleFooNotFound(FooNotFoundException exception, WebRequest request) {
return handleExceptionInternal(exception, "Foo Not Found",
new HttpHeaders(), HttpStatus.NOT_FOUND, request);
}
}

JUnit Parameterized tests not running in isolation with Mockito, Spring, Reflection and AspectJ

I have the below test class, which has been stripped to the bare minimum needed to reproduce the issue:
#RunWith(Parameterized.class)
#ContextConfiguration(locations = { "classpath:restful-service-test-context.xml" })
#DirtiesContext(classMode = DirtiesContext.ClassMode.AFTER_EACH_TEST_METHOD)
public class ResftulServiceTest {
#Autowired
#Qualifier("failedAspectTestMessage")
private String failedAspectTestMessage;
#Autowired
private ProviderService ProviderService;
private String methodName;
private Set valuesToReturnByMock;
private TestContextManager testContextManager;
public ResftulServiceTest(String methodName, String[] valuesToReturnByMockArray) {
this.methodName = methodName;
this.valuesToReturnByMock = new HashSet<>(Arrays.asList(valuesToReturnByMockArray));
}
#Parameterized.Parameters
public static Collection values() {
return Arrays.asList(new Object[][] { { "getCountries", new String[] { "GB", "US" } }, });
}
#Before
public void setUpSpringContext() throws Exception {
testContextManager = new TestContextManager(getClass());
testContextManager.prepareTestInstance(this);
}
#Test
public void testGetValues_Fail_MyException() throws Exception {
Method methodInProviderService = ProviderService.class.getDeclaredMethod(methodName);
Mockito.when(methodInProviderService.invoke(ProviderService))
.thenThrow(new MyException(failedAspectTestMessage, StatusCodeType.ERROR));
}
#Test
public void testGetValues_Fail_Exception() throws Exception {
Method methodInProviderService = ProviderService.class.getDeclaredMethod(methodName);
Mockito.when(methodInProviderService.invoke(ProviderService))
.thenThrow(new AspectException(failedAspectTestMessage));
}
}
If I run each of the tests separately, they work fine. However, if I run all of them, testGetValues_Fail_Exception fails on the Mockito line with error:

If I replace the .thenThrow in testGetValues_Fail_MyException with .thenReturn, it all works fine, so at some point the isolation is being broken. How can I fix this problem?
Try using Mockito.reset() passing your mock. Usually this is done to prevent interaction between test. It resets the previously configured behavior of the mock. However, in your case I cannot give more details as you are using an unusual combination of Parameterized with Spring context and DirtiesContext.
