And of course you can just define your Async interface methods by
Request myAsyncMethod(AsyncCallback<String> callback);
instead of
void myAsyncMethod(AsyncCallback<String> callback);
then you can use normal Mockito-syntax, ala
when(service.myAsyncMethod(any(AsyncCallback.class))).thenAnswer(new
Answer<Request>(){
Request answer(InvocationOnMock invocation) {
Object[] args = invocation.getArguments();
AsyncCallback<String> callback = (AsyncCallback<String>)
args[args.length - 1];
callback.onSuccess(mockServerAnswer);
return mockRequest;
}
Having a Request return type for AsyncMethods has the advantage, that
you can use request.cancel() anyways, which sometimes comes in
handy... And of course, you should use dependency injection, as
mentioned above, i.e. never call GWT.create(MyService.class), but
instead use Gin and write the constructor as
@Inject
public MyWidget(MyServiceAsync service){
this.service = service;
}
or push the async service into the constructor by hand/factory, so you
can use a mock service with Mockito in your tests...
