### Question:
DelegateLienzoPanel implements LienzoPanel { @Override public LienzoPanel show(final LienzoLayer layer) { getDelegate().show(layer); return this; }  @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 testShow() { LienzoLayer layer = mock(LienzoLayer.class); tested.show(layer); verify(delegate, times(1)).show(eq(layer)); }
@Test public void testShowSize() { LienzoLayer layer = mock(LienzoLayer.class); tested.show(layer, 100, 200); verify(delegate, times(1)).show(eq(layer), eq(100), eq(200)); }
