I have a test with an Error that gives no good information. The only piece of the stack that involves my code is the method call in the test which fails.

WebTarget t = target("/api/url");
System.out.println(t.toString());
Invocation.Builder b = t.request();
System.out.println(b.toString());
String respString = b.get(String.class); // <-- ERROR IS HERE
System.out.println("XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX");
System.out.println(respString);
}
}
The class I'm trying to test works fine when I run it with grizzly and render it manually with a browser.
#Path("url")
public class FakeSiteminderService {
#GET
#Produces(MediaType.TEXT_HTML)
#Template(name = "/foo")
public Map<String, String> get(
#Context HttpHeaders hh
) {
Map<String, String> ctx = new HashMap<>();
if (hh.getRequestHeader("FULLNAME") != null) {
ctx.put("FULLNAME", hh.getRequestHeader("FULLNAME").get(0));
ctx.put("EMAIL", hh.getRequestHeader("EMAIL").get(0));
}
return ctx;
}
You may be able to get some more information out or a different traceback if you put some code like this somewhere in your package:
#Provider
public class CustomExceptionMapper implements
ExceptionMapper<Throwable> {
#Override
public Response toResponse(Throwable ex) {
System.out.println("EXCEPTIONMAPPER!!!!!!!!!!!!!!!!!!!!");
System.out.println(Exceptions.getStackTraceAsString(ex)); // <--
return Response.status(500).entity(
Exceptions.getStackTraceAsString(ex)
).type("text/plain").build();
}
}

I am writing unit-test class using Junit and I am also using power-mocking concept to mock the objects which are created inside the method.
Test Class :
#PowerMockIgnore("javax.management.*")
#RunWith(PowerMockRunner.class)
#PrepareForTest(Client.class)
public class ClientTest {
private static final Logger logger = LoggerFactory
.getLogger(ClientTest.class);
private static Client client;
private static DetailsDao detailsDao;
public static Session session;
private static IDevicesDao devicesDao;
private static IUserDao userDao;
private static IDao dao;
private static IValidator validator;
#BeforeClass
public static void setup() throws Exception {
logger.info("*************** Testing ClientTest Started *******************");
session = Connection.get(); // Here getting error
detailsDao = mock(DetailsDao.class);
devicesDao = mock(IDevicesDao.class);
userDao = mock(UserDao.class);
validator = mock(IValidator.class);
dao= mock(IDao.class);
client = new Client(detailsDao, session, devicesDao, userDao, dao, validator);
}
If I romove #RunWith(PowerMockRunner.class) then its working fine... But I have to run this test using PowerMockRunner only.

I am not getting ... why it is not able to create cassandra session using power mock runner....
Mocked the session also, then it runs without any errors.
replaced
session = Connection.get();
with
session = mock(Session.class);
I can't get Powermock work with TestNG. The same code adjusted to JUnit works fine, but somehow in TestNG it fails.

So what am I missing here?
I suspect this may be the same issue and solution as this question. In other words make sure you are using the org.powermock.modules.testng.PowerMockObjectFactory. But as #fge says, you should #PrepareForTest the class containing the static method(s) to mock, which should not be the test class itself...
I've written a simple RestEasy client proxy to perform an iTunes search. It looks like this:
#Path("/")
public interface AppleAppStoreLookupClient {
/**
* Attempts to lookup an apple app store item by its ID
*
* #param id
* The item ID
* #return The app details
*/
#GET
#Path("/lookup")
#Produces(value = { "text/javascript" })
public AppleAppDetailsResponse lookupByID(#QueryParam("id") String id);
}
My JSON model class is simple, as well. In fact, for the first call all I want is the "resultCount" value, just to make sure connectivity works.
#XmlRootElement
#XmlAccessorType(XmlAccessType.NONE)
public class AppleAppDetailsResponse implements Serializable {
private static final long serialVersionUID = 8881587082097337598L;
#XmlElement
private int resultCount = -1;
...getters and setters...
}
However, when I run a simple test, I get the following Exception:

I'm running RestEasy 2.3.6. Any idea what could be causing such an error?
Do you have a json provider on your classpath? If you are using maven, try adding this dependency:
<dependency>
<groupId>org.jboss.resteasy</groupId>
<artifactId>resteasy-jettison-provider</artifactId>
<version>2.3.6.Final</version>
</dependency>
http://docs.jboss.org/resteasy/docs/2.3.6.Final/userguide/html_single/#JAXB_+_JSON_provider
EDIT:
Normally, one would use the content type application/json and not text/javascript. I'm not sure why you are using text/javascript?
Anyways, if your endpoint returns only text/javascript, you can always modify the Content-Type-header in an interceptor:
ResteasyProviderFactory factory = new ResteasyProviderFactory();
RegisterBuiltin.register(factory);
factory.getClientExecutionInterceptorRegistry().register(
new ClientExecutionInterceptor() {
#Override
public ClientResponse execute(ClientExecutionContext ctx) throws Exception {
ClientResponse response = ctx.proceed();
if("text/javascript".equals(response.getHeaders().getFirst(HttpHeaders.CONTENT_TYPE))){
response.getHeaders().putSingle(HttpHeaders.CONTENT_TYPE, MediaType.APPLICATION_JSON);
}
return response;
}
});
ProxyFactory.create(Service.class, URI.create("http://url-to-your-sevice"), new ApacheHttpClient4Executor(), factory);
I am trying to implement a JUnit test to test an actor.
I have this ActorTest :
import org.junit.Test;
import play.libs.Akka;
import playtests.PlayFrameworkTest;
import akka.actor.Actor;
import akka.actor.Props;
import akka.actor.UntypedActorFactory;
import akka.testkit.TestActorRef;
public class ActorTest {
public static FakeApplication dummy;
#BeforeClass
public static void startApp() {
dummy = Helpers.fakeApplication(Helpers.inMemoryDatabase());
Helpers.start(dummy);
}
#AfterClass
public static void stopApp() {
Helpers.stop(dummy);
}
#Test
public void test() throws Exception {
final String myParameter = "someParameter";
#SuppressWarnings("serial")
TestActorRef<MyActor> actorRef = TestActorRef.create(Akka.system(), new Props(new UntypedActorFactory() {
#Override
public Actor create() {
return new MyActor(myParameter);
}
}), "testActor");
MyActor actor = actorRef.underlyingActor();
String message = "message";
actor.apply(message);
actor.receive();
}
}
When I try to run it (both on eclipse and with 'play test' commandline) is I get this exception thrown at the line of the TestActorRef.create()

I have looked http://doc.akka.io/docs/akka/snapshot/java/testing.html
and
http://doc.akka.io/docs/akka/snapshot/scala/testing.html
and all I could find on the play framework page.
What am I missing? Why is it not running? I get the same exception if I get my system from Akka.system() and ActorSystem.apply() ... same thing when I pass it my fakeApplication or not.
(To summarise the comments above…) The class scala.concurrent.duration.Duration was first included with Scala 2.10. At the time of writing Akka 2.1 and Play 2.1 are the best releases to work with Scala 2.10.
I am testing a simple thing in my DB-Application. To create a product. For this I use Junit tests and here is the test that always fail, instead the expected result to turn green(passes)...
#Test
public void testCreate(){
Produkt test = new Produkt(20, "junit", "junitk", false, 900.67, true, true);
handler.createProdukt(test);
}
when I try it out simply with a main method(just creating a new Produkt and look if that works...) the create function works great and created this Produkt.
What am I doing wrong?
PS.: here is the code where I set up the tests:
#Before
public void setUp() throws SQLException, ClassNotFoundException{
try {
this.shandler = new ServiceHandler();
this.setServiceHandler(shandler);
manager.getConnection();
manager.getConnection().setAutoCommit(false);
} catch (SQLException ex) {
System.err.println("ERROR:");
ex.printStackTrace();
}
}
#After

UPDATE
I guess you mean the failure trace:

Assuming your code snippets are accurate, your setUp() method instantiates a shandler field while your testCreate() test uses a handler field. And the stacktrace clearly shows that you have a NullPointerException in testCreate(). So the thing that you are doing wrong is trying to call a method on an object whose value is null.
