Not able to use install in test class

[Soubhratra Das]

Hi all,

I have starting up with GWTP and Jukito. I am getting compilation error while trying to use install(new clientModule()) in my test class. Below is the code fragment..please suggest what is wrong here. Thanks in advance.

@RunWith(JukitoRunner.class)

public class MainPagePresenterTest extends XXXBasePresenterTest {

/**

  * Guice test module.

  */

public static class Module extends XXXBaseTestModule {

   @Override

   protected void configurePresenterTest() {

                install(new ClientModule());

    forceMock(ObjectCommandOptionsPopupPresenter.class);

   }

}

 

// SUT

@Inject

MainPagePresenter presenter;

@Inject 

MainPagePresenter.MyView view;

.............

}

public abstract class XXXBaseTestModule extends JukitoModule {

@Override

protected void configureTest() {

 

configurePresenterTest();

}

protected abstract void configurePresenterTest();

}

public class ClientModule extends AbstractPresenterModule {

@Override

protected void configure() {

// Default implementation of standard resources

install(new DefaultModule(xxxPlaceManager.class));

....... 

//Other bindings

   }

Getting the following error - 

Caused by: java.lang.ClassCastException: com.xxx.xxx.webapp5.client.gin.ClientModule cannot be cast to com.google.inject.Module

        at com.xxx.xxx.webapp5.XXXBaseTestModule.configureTest(XXXBaseTestModule.java:13)

Thanks,

SD

What is the code for ClientModule?

I provided the snippet in the original mail but possibly lost in other code. Here it is -

public class ClientModule extends AbstractPresenterModule {

@Override

protected void configure() {

// Default implementation of standard resources

install(new DefaultModule(DbvsPlaceManager.class));

// Constants

bindConstant().annotatedWith(DefaultPlace.class).to(

NameTokens.contentPage);

..............//Other bindings....

}

Thanks,

And the other bindings? :D

At first it's weird, but maybe there's a binding that involve "client side code" that isn't compatible with JUnit.

What I suggest you do is to only bind manually what you need for that one test and not the whole module itself.

Cheers,

I think the problem has nothing to do with guice or jukito.

First of all, Just to make sure: you get a ClassCastException and not a compilation error. Because those are two different things.
So if I'm wrong and you do get a compilation error (when you are compiling your project and not while running the test) please correct me.

If you get the following ClassCastException

java.lang.ClassCastException: com.xxx.xxx.webapp5.client.gin.ClientModule cannot be cast to com.google.inject.Module

        at com.xxx.xxx.webapp5.XXXBaseTestModule.configureTest(XXXBaseTestModule.java:13)

It means that com.xxx.xxx.webapp5.client.gin.ClientModule is not a child class com.google.inject.Module.
Now I don't have your entire Object hierarchy. But I suggest you do the following:
1) make sure ClientModule implements com.google.inject.Module
2) If 1) is true it is most likely a problem with your path. make sure that the jars which are used at compile time are the same as the ones used at runtime.
