### Question:
RadosClient extends DB { @Override public Status delete(String table, String key) { try { ioctx.remove(key); } catch (RadosException e) { return new Status("ERROR-" + e.getReturnValue(), e.getMessage()); } return Status.OK; }  void init(); void cleanup(); @Override Status read(String table, String key, Set<String> fields, HashMap<String, ByteIterator> result); @Override Status insert(String table, String key, HashMap<String, ByteIterator> values); @Override Status delete(String table, String key); @Override Status update(String table, String key, HashMap<String, ByteIterator> values); @Override Status scan(String table, String startkey, int recordcount, Set<String> fields,
      Vector<HashMap<String, ByteIterator>> result); static final String CONFIG_FILE_PROPERTY; static final String CONFIG_FILE_DEFAULT; static final String ID_PROPERTY; static final String ID_DEFAULT; static final String POOL_PROPERTY; static final String POOL_DEFAULT; }### Answer:
@Test public void deleteTest() { Status result = radosclient.delete(TABLE_NAME, KEY0); assertEquals(Status.OK, result); }
