### Question:
Record implements Iterable<Entry> { public void add(Entry entry) { if (entry == null) throw new NullPointerException("The entry provided to this record was null"); this.entries.add(entry); } Record();  Record(final String uuid, final String feedName); String getUuid(); String getFeedName(); void setFeedName(final String feedName); void add(Entry entry); void add(Entry... entries); int size(); Entry get(int index); @Override Iterator<Entry> iterator();  }### Answer:
@Test(expected = NullPointerException.class) public void testAddNullCV() { record.add((Entry) null); }
@Test(expected = NullPointerException.class) public void testAddNullEntries() { Record testRecord = new Record(); testRecord.add(null, null, null); }
@Test(expected = NullPointerException.class) public void testAddNullEntryInMultipleEntries() { Record testRecord = new Record(); testRecord.add(value1, null, value2); }
