### Question:
NetworkDefinition { public List<Node> getNode() { if (node == null) { node = new ArrayList<Node>(); } return this.node; }  Document getDocument(); void setDocument(Document value); List<Node> getNode(); List<Bus> getBus();  }### Answer:
@Test public void testGetNode() { List<String> list = new ArrayList<String>(); list.add(new String("Motor ACME")); list.add(new String("Navigation")); list.add(new String("Fuel")); list.add(new String("Climate")); list.add(new String("Brake ACME")); list.add(new String("Steering")); list.add(new String("Crypto")); list.add(new String("CruiseControl")); list.add(new String("Clock")); list.add(new String("Gearbox")); list.add(new String("Motor alternative supplier")); list.add(new String("BodyComputer")); list.add(new String("Radio")); list.add(new String("DoorLocking")); list.add(new String("Seat")); list.add(new String("BodyControl")); list.add(new String("Brake alternative supplier")); list.add(new String("ParkDistance")); for (Node n : netdef.getNode()) { assertTrue("Unexpected node", list.contains(n.getName())); } }
