### Question:
DelegateLienzoPanel implements LienzoPanel { @Override public void destroy() { getDelegate().destroy(); }  @Override LienzoPanel show(final LienzoLayer layer); @Override LienzoPanel show(final LienzoLayer layer,
                            final int width,
                            final int height); @Override LienzoPanel setPixelSize(final int wide,
                                    final int high); @Override LienzoPanel focus(); @Override int getWidthPx(); @Override int getHeightPx(); @Override void setBackgroundLayer(final Layer layer); @Override Bounds getLocationConstraints(); @Override void destroy(); @Override Widget asWidget(); @Override LienzoBoundsPanel getView();  }### Answer:
@Test public void testDestroy() { tested.destroy(); verify(delegate, times(1)).destroy(); }
