### Question:
ChannelzProtoUtil { static SocketOption toSocketOptionAdditional(String name, String value) { Preconditions.checkNotNull(name); Preconditions.checkNotNull(value); return SocketOption.newBuilder().setName(name).setValue(value).build(); } private  ChannelzProtoUtil();  static final String SO_LINGER; static final String SO_TIMEOUT; static final String TCP_INFO; }### Answer:
@Test public void toSocketOptionAdditional() { assertEquals( sockOptAdditional, ChannelzProtoUtil.toSocketOptionAdditional("SO_MADE_UP_OPTION", "some-made-up-value")); }
