### Question:
WiresUtils { public static boolean isWiresShape(final ShapeView<?> shapeView) { return shapeView instanceof WiresShape; }  static Point2D getAbsolute(final IDrawable<?> shape); static Node getNode(final AbstractCanvasHandler canvasHandler,
                               final WiresContainer shape); static Node getNode(final AbstractCanvasHandler canvasHandler,
                               final WiresMagnet magnet); static Edge getEdge(final AbstractCanvasHandler canvasHandler,
                               final WiresConnector connector); static boolean isWiresShape(final ShapeView<?> shapeView); static boolean isWiresContainer(final ShapeView<?> shapeView); static boolean isWiresConnector(final ShapeView<?> shapeView); static boolean isWiresShape(final WiresContainer wiresShape); static boolean isWiresLayer(final WiresContainer wiresShape); static void assertShapeUUID(final IDrawable<?> shape,
                                       final String uuid); static String getShapeUUID(final IDrawable<?> shape); static void assertShapeGroup(final IDrawable<?> shape,
                                        final String group); static String getShapeGroup(final IDrawable<?> shape);  }### Answer:
@Test public void isWiresShapeWhenWiresContainer() { final WiresContainer wc = new WiresContainer(new Group()); assertFalse(WiresUtils.isWiresShape(wc)); }
@Test public void isWiresShapeWhenWiresLayer() { final Layer l = new Layer(); final WiresLayer wl = new WiresLayer(l); assertTrue(WiresUtils.isWiresShape(wl)); }
@Test public void isWiresShapeWhenUnregisteredWiresShape() { final WiresShape ws = new WiresShape(new MultiPath()); assertFalse(WiresUtils.isWiresShape(ws)); }
