                               RaftOptions raftOptions, String path); @Override void close(); @Override boolean init(final Void v); @Override void shutdown(); @Override SnapshotMeta load(); @Override String generateURIForCopy(); @Override String getPath(); @Override Set<String> listFiles(); @Override Message getFileMeta(final String fileName);  }### Answer:
@Test public void testListFiles() { assertTrue(this.reader.listFiles().contains("testFile")); }
