### Question:
BlockingQueue { public synchronized int consumerCount() { return consumers; }  synchronized void enqueue(Object o); synchronized void requeue(Object o); synchronized Object dequeue(); synchronized Object dequeue(long timeout); synchronized void close(); synchronized int consumerCount(); synchronized int consumerDeficit(); synchronized boolean ready(); synchronized int pending(); LinkedList getQueue(); void setQueue(LinkedList queue);  }### Answer:
@Test public void testConsumerCount() throws Throwable { int result = new BlockingQueue().consumerCount(); assertEquals(0, result, "result"); }
