Injection in JUnit test

[Sydney]

I have a service that I want to test but it requires dependencies. I use Guice

The service:

    @Inject

    public MyService(ObjectDatastore datastore,

            MyDao dao1, OtherDao dao2) {

    }

One Dependency:

    @Inject

    public MyDao(final Provider<ObjectDatastore> datastoreProvider) {

    }

How do you setup Guice to inject the dependency into a JUnit test?

[Sydney]

Sometimes I should look by myself before posting the question too quickly on the group. Here is the answer:

        Injector myInjector = Guice.createInjector(new MyTestModule());

        service = myInjector.getInstance(MyService.class);

The test module

public class MyTestModule extends AbstractModule {

    @Override

    protected void configure() {

        bind(ObjectDatastore.class).toProvider(

                AnnotationObjectDatastoreProvider.class);

        bind(MyService.class).in(Singleton.class);

    }

}

In general, I don't use Guice in tests. I prefer to manually instantiate the class (MyService in your exemple) and pass the dependencies (usualy, mocks) on the constructor myself

If you like Guice tests, take a look at our other project, Jukito:

I personally love it! :)

Hi

Could you please provide one sample test case with Actions and
Presenters developed in Jukito.
