### Question:
DisplayHelperBase implements DisplayHelper { @Override public Point getRawDisplaySize() { return getDisplaySize(); } DisplayHelperBase(final Context context); @SuppressWarnings("deprecation") @Override int getDisplayAngle(); @SuppressWarnings("deprecation") @Override Point getDisplaySize(); @Override Point getRawDisplaySize();  }### Answer:
@Test public void testGetRawDisplaySize() { final Point displaySize = new DisplayHelperBase(Robolectric.application).getRawDisplaySize(); assertNotNull(displaySize); assertEquals(displaySize.x, mShadowDisplay.getWidth()); assertEquals(displaySize.y, mShadowDisplay.getHeight()); }
