### Question:
ChannelzProtoUtil { static SocketRef toSocketRef(InternalWithLogId obj) { return SocketRef .newBuilder() .setSocketId(obj.getLogId().getId()) .setName(obj.toString()) .build(); } private  ChannelzProtoUtil();  static final String SO_LINGER; static final String SO_TIMEOUT; static final String TCP_INFO; }### Answer:
@Test public void toSocketRef() { assertEquals(socketRef, ChannelzProtoUtil.toSocketRef(socket)); }
