### Question:
ReleaseRequestQueue { public void add(Address destination, Coin amount) { entries.add(new Entry(destination, amount)); } ReleaseRequestQueue(List<Entry> entries); List<Entry> getEntries(); void add(Address destination, Coin amount); void process(int maxIterations, Processor processor);  }### Answer:
@Test public void add() { Assert.assertFalse(queue.getEntries().contains(new ReleaseRequestQueue.Entry(mockAddress(10), Coin.valueOf(10)))); queue.add(mockAddress(10), Coin.valueOf(10)); Assert.assertTrue(queue.getEntries().contains(new ReleaseRequestQueue.Entry(mockAddress(10), Coin.valueOf(10)))); }
