### Question:
PNode2VNodeMapping { public List<Integer> getVNodes(int pNode) { return vpmMapping.get( pNode ); } PNode2VNodeMapping(int vNodes, int pNodeCount); List<Integer> getVNodes(int pNode); int getPNodeCount(); List<List<Integer>> getVpmMapping();  }### Answer:
@Test public void testGetVNodes() { PNode2VNodeMapping mapping = new PNode2VNodeMapping(12, 3); System.out.println( "vNodes: of (12,3): " + mapping); List<Integer> vNodes = mapping.getVNodes(1); System.out.println( "vNodes: of (12,3:1): " + vNodes ); Assert.assertEquals(6, vNodes.get(0).intValue()); Assert.assertEquals(7, vNodes.get(1).intValue()); Assert.assertEquals(8, vNodes.get(2).intValue()); Assert.assertEquals(9, vNodes.get(3).intValue()); }
