title: GWTP unit testing using Mockito
body: <p>I am trying to use Mockito to test my GWTP application.</p>
  
  <p>I am trying to Mock my View,Proxy,Placemanager and eventbus.
  I tried using 
  @Mock
  AbcView abc;</p>
  
  <p>and Abcview abc = Mockito.mock(AbcView.class);</p>
  
  <p>However every time the mocked view is instantiated as null.
  How shall i address the same?
  Once the view is mocked i will be able go on with testing my presenter class, as the constructor of presenter has following code:
  getView().setUiHandlers( this );</p>
  
  <p>so until view is instantiated properly null pointer exception is thrown.</p>
