Can someone explain me why my JUnit test fail:
notNullMethodTest() uses #NotNull --> success
nonnullMethodTest() uses #Nonnull --> fail
Unexpected exception, expected<java.lang.NullPointerException> but
was<java.lang.IllegalArgumentException>
package com;
import java.util.Objects;
import javax.annotation.Nonnull;
import javax.validation.constraints.NotNull;
import org.junit.Test;
public class AnnotationTest {
private void nonnullMethod(#Nonnull String arg) {
Objects.requireNonNull(arg);
}
#Test(expected = NullPointerException.class)
public void nonnullMethodTest() {
nonnullMethod(null);
}
private void notNullMethod(#NotNull String arg) {
Objects.requireNonNull(arg);
}
#Test(expected = NullPointerException.class)
public void notNullMethodTest() {
notNullMethod(null);
}
}
Here the StackTrace:

IntelliJ has recently started generating this assertion code by default. If you don't want this behavior, you can deactivate it in the compiler settings:
The configuration behind the "configure annotations" button allows you to specify which annotations should be taken into account. This is why it behaves differently when you switch annotations.

I have started implementing Swagger with version 2.9.2 recently. It worked well without Jackson in other project but as I added same code with Jackson dependency my integration tests were started failing due to not able to covert it(XML string) into Json object.
Tried with different versions of Jackson data format and swagger.
My DTO class:
#Data
#AllArgsConstructor
#NoArgsConstructor
#Wither
public class PartsInfoDTO {
// TODO: 08/10/18 This class should be removed after lexcom start giving remark_line instead of RemarkLine for ex.
#JsonProperty("illustration")
private String Illustration;
#JsonProperty("quantity")
private String Quantity;
#JsonProperty("price")
private Price Price;
#JsonProperty("remark_line")
private String remarkLine;
#JsonProperty("part_number")
#ApiModelProperty(name = "part_number")
private String partNumber;
#JsonProperty("denomination_line")
private String[] denominationLine;
public PartsInfoDTO(PartsInfo partsInfo) {
setDenominationLine(partsInfo.getDenominationLine());
setIllustration(partsInfo.getIllustration());
setPartNumber(partsInfo.getPartNumber());
setPrice(partsInfo.getPrice());
setQuantity(partsInfo.getQuantity());
setRemarkLine(partsInfo.getRemarkLine());
}
}
My Swagger config:
#Configuration
#EnableSwagger2
public class PartsSwaggerConfiguration extends WebMvcConfigurationSupport {
#Bean
public Docket api() {
return new Docket(DocumentationType.SWAGGER_2)
.select()
.apis(RequestHandlerSelectors.basePackage("com.package.example"))
.paths(regex(PART_INFO_API))
.build();
}
}

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");
}
Stack:
java.lang.NullPointerException

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.
I want to test a MVP-Pattern. So i have a Presenter class, which shall invoke the View methods when certain buttons are clicked. Now I want to verify, that the Presenter really invokes the Method, so I wrote these tests:
Test Class:
import org.junit.Before;
import org.junit.Test;
import org.junit.runner.RunWith;
import org.mockito.Mock;
import org.mockito.MockitoAnnotations;
import org.mockito.runners.MockitoJUnitRunner;
import static org.mockito.Mockito.verify;
#RunWith(MockitoJUnitRunner.class)
public class MainPresenterTest {
#Mock
private MainContract.View view;
private MainPresenter presenter;
#Before
public void setUp() throws Exception {
MockitoAnnotations.initMocks(this);
presenter = new MainPresenter(view);
}
#Test
public void handleScanButtonClicked() {
presenter.handleScanButtonClicked();
verify(view).showScanScreen();
}
#Test
public void handleBackButtonClicked() {
presenter.handleBackButtonClicked();
verify(view).showMainScreen();
}
}
Presenter Class:
public class MainPresenter implements MainContract.Presenter {
private final MainContract.View view;
public MainPresenter(MainContract.View view) {
this.view = view;
}
#Override
public void handleScanButtonClicked() {
view.showScanScreen();
}
#Override
public void handleBackButtonClicked() {
view.showMainScreen();
}
}
MainContract Interface
public interface MainContract {
/** handles UI-interaction **/
interface Presenter {
void handleScanButtonClicked();
void handleBackButtonClicked();
}
/** handles showing/hiding UI-elements and screens **/
interface View {
void showScanScreen();
void showMainScreen();
void showWebViewScreen();
}
}
My Testing Dependencies in build.gradle:
testCompile 'junit:junit:4.12'
testCompile 'org.mockito:mockito-all:1.10.19'
Test Error Message:
Wanted but not invoked:

My Project Structure
When I now run the tests without an AVD running, they will fail. I want to run those tests on my local machine only, and there should be no interactions with Android specificly, right? But to let the tests pass, I need to start an AVD, and build + deploy the APK.
Why is this, and how can I run those kind of tests properly on my local machine?
Thanks in advance
You are not telling the framework what it should do when it encounters this line
view.showScanScreen()
and
view.showMainScreen()
do
doNothing().when(view).showScanScreen();
doNothing().when(view).showMainScreen();
You test methods will be like this
#Test
public void handleScanButtonClicked() {
doNothing().when(view).showScanScreen();
presenter.handleScanButtonClicked();
verify(view).showScanScreen();
}
#Test
public void handleBackButtonClicked() {
doNothing().when(view).showMainScreen();
presenter.handleBackButtonClicked();
verify(view).showMainScreen();
}
If you want to run your tests on your local machine's JVM, then you need to put them in test package, not in androidTest package. androidTest is used for instrumentation tests and will require Android framework to run.
Check out this post for their differences.
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.
I am trying to use selenium with Play 2.4.6 [Java]. I am using Play-Java template as an example. When I'm trying to run IntegrationTest.java which is shipped with this template by default, I get the below exception:
import org.junit.*;
import play.test.*;
import play.libs.F.*;
import static play.test.Helpers.*;
import static org.junit.Assert.*;
public class IntegrationTest {
/**
* add your integration test here
* in this example we just check if the welcome page is being shown
*/
#Test
public void test() {
running(testServer(3333, fakeApplication(inMemoryDatabase())), HTMLUNIT, new Callback<TestBrowser>() {
public void invoke(TestBrowser browser) {
browser.goTo("http://localhost:3333");
assertTrue(browser.pageSource().contains("Your new application is ready."));
}
});
}
}

So what I am missing here. I've tried to use "WithBrowser" but I got the same error, here is my code
import org.junit.*;
import play.test.*;
import static org.junit.Assert.*;
public class BrowserFunctionalTest extends WithBrowser {
#Test
public void runInBrowser() {
browser.goTo("/");
assertNotNull(browser.$("title").getText());
}
}
