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:

The version of Elasticsearch is 6.5.3 and the version of RestHighLevelClient is 6.5.3, too.
I wrote the above code with reference to the official tutorial:https://www.elastic.co/guide/en/elasticsearch/client/java-rest/6.5/java-rest-high-delete-index.html

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.

JUnit test fails when method arg is annotated #Nonnull

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);
}
}

Thanks

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.

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.
