### Question:
BinaryTimeTree { public void clear() { nodeClear(myTopNode); myTopNode.setRange(null); } BinaryTimeTree();  BinaryTimeTree(int maxValuesPerNode, int maxDepth); void clear(); int countInRange(TimeSpan range); CountReport countsInBins(TimeSpan overAllRange, int numberOfBins); TIntList countsInRanges(List<TimeSpan> countTimes); List<E> findInRange(TimeSpan range); boolean insert(E tsProvider); boolean insert(List<E> collection); int internalSize(BTreeNode<E> node); int maxValuesPerNodeInteral(BTreeNode<E> node, int maxValues); int queryMaxValuesPerNode(); int size();  }### Answer:
@Test public void testClear() { myTestObject.clear(); assertEquals(0, myTestObject.size()); }
