the class ChannelzProtoUtil method toChannel.

static Channel toChannel(InternalInstrumented<ChannelStats> channel) {
    ChannelStats stats = getFuture(channel.getStats());
    Channel.Builder channelBuilder = Channel.newBuilder().setRef(toChannelRef(channel)).setData(extractChannelData(stats));
    for (InternalWithLogId subchannel : stats.subchannels) {

    ChannelData protoStats = channelData.toBuilder().setTrace(channelTrace.toBuilder().addAllEvents(Arrays.asList(protoEvent1, protoEvent2)).build()).build();
    assertEquals(ChannelzProtoUtil.extractChannelData(stats), protoStats);
}
