How do I configure RoboAttributeSet for a custom view in Robolectric?



I am testing a (working) compound control (aka. custom view) with my own attributes and trying to use RoboAttributeSet to configure the attributes for the view. I haven't found comprehensive examples or documentation on this feature and what values to use with my attribute creation when using the constructor. I'm sure it's an easy fix, but I haven't bee able to find it.


I have reviewed these questions: RoboAttributeSet, Custom view inflation error, and Shadowing custom views ... and the rest of the internet to no avail.


Note: My full package name is: com.colabug.local.food


Note: I used a file name that is not attrs.xml as described in the Android tutorial.


CoverViewTest.java



public class CoverViewTest
{
private Activity activity;
private CoverView coverView;

// Data
private Delicacy data;

// UI
private RatingBar ratingBar;

@Before
public void setUp() throws Exception
{
activity = createActivity();
coverView = getCoverView( activity, null );
data = createDummyData( false, 2, false );
coverView.setData( data );

ratingBar = (RatingBar) coverView.findViewById( R.id.cover_view_rating_bar );
}

private CoverView getCoverView( Activity activity,
RoboAttributeSet attributeSet )
{
CoverView view;
view = new CoverView(Robolectric.application.getApplicationContext(), attributeSet);

// view = (CoverView) LayoutInflater.from( activity )
// .inflate( R.layout.cover_view,
// new CoverView( activity ),
// true );

return view;
}

@Test
public void showRatingBarAttribute_shouldShowRatingBar() throws Exception
{
ArrayList<Attribute> attributes = new ArrayList<Attribute>();
attributes.add( new Attribute( "com.colabug.local.food:cover_attrs/showRatingBar", String.valueOf( true ), "com.colabug.local.food") );
RoboAttributeSet attributeSet = new RoboAttributeSet( attributes,
Robolectric.application.getResources(),
CoverView.class );

CoverView view = getCoverView( activity, attributeSet );
view.setData( createDummyData( false, 2, false ) );
assertViewIsVisible( view.findViewById( R.id.cover_view_rating_bar ) );
}
}
