Node extends Properties implements ClockListener, Comparable<Node> { public int getIconSize() { return iconSize; }  int getID(); void setID(int ID); Topology getTopology(); void onSelection(); void onStart(); void onStop(); void onPreClock(); void onClock(); void onPostClock(); void onMovement(); void onMessage(Message message); void onLinkAdded(Link link); void onLinkRemoved(Link link); void onDirectedLinkAdded(Link link); void onDirectedLinkRemoved(Link link); void onSensingIn(Node node); void onSensingOut(Node node); void die(); boolean isDying(); double getX(); double getY(); double getZ(); Color getColor(); void setColor(Color color); void setIcon(String fileName); String getIcon(); int getIconSize(); void setIconSize(int iconSize); Object getLabel(); void setLabel(Object label); double getCommunicationRange(); void setCommunicationRange(double range); boolean isWirelessEnabled(); void enableWireless(); void disableWireless(); void setWirelessStatus(boolean enabled); double getSensingRange(); void setSensingRange(double range); Point getLocation(); void setLocation(double x, double y); void setLocation(double x, double y, double z); void setLocation(Point loc); void wrapLocation(); void translate(double dx, double dy); void translate(double dx, double dy, double dz); int getTime(); double getDirection(); void setDirection(double angle); void setDirection(Point p); void setDirection(Point p, boolean opposite); void move(); void move(double distance); Link getInLinkFrom(Node n); Link getOutLinkTo(Node n); Link getCommonLinkWith(Node n); List<Link> getInLinks(); List<Link> getOutLinks(); List<Link> getLinks(); List<Link> getLinks(Link.Orientation orientation); @Deprecated List<Link> getLinks(boolean directed); boolean hasInNeighbor(Node node); List<Node> getInNeighbors(); boolean hasOutNeighbor(Node node); List<Node> getOutNeighbors(); List<Node> getSensedNodes(); boolean hasNeighbors(); boolean hasNeighbor(Node node); List<Node> getNeighbors(); List<Message> getMailbox(); List<Message> getOutbox(); void send(Node destination, Message message); @Deprecated void send(Node destination, Object content); void sendRetry(Node destination, Message message); @Deprecated void sendRetry(Node destination, Object content); void sendAll(Message message); @Deprecated void sendAll(Object content); double distance(Node n); double distance(double x, double y); double distance(Point p); double distance(double x, double y, double z); @Override int compareTo(Node o); String toString(); static final Color DEFAULT_COLOR; static final int DEFAULT_ICON_SIZE; static final double DEFAULT_DIRECTION; }### Answer:
@Test void iconSize_defaultValue_ok() { Node node = createDefaultNode(); assertEquals(DEFAULT_ICON_SIZE, node.getIconSize()); }
