### Question:
MultiplexedChannelRecord { boolean acquireStream(Promise<Channel> promise) { if (claimStream()) { releaseClaimOnFailure(promise); acquireClaimedStream(promise); return true; } log.warn("No available streams on this connection: {}", parentChannel.remoteAddress()); return false; } MultiplexedChannelRecord(Channel parentChannel, int maxConcurrentStreams, Long allowedIdleTimeInMs,
      ChannelInitializer streamChannelInitializer); Channel getParentChannel();  }### Answer:
@Test public void availableStream0ShouldBeFalse() { loopGroup.register(channel).awaitUninterruptibly(); Promise<Channel> channelPromise = new DefaultPromise<>(loopGroup.next()); channelPromise.setSuccess(channel); MultiplexedChannelRecord record = new MultiplexedChannelRecord(channel, 0, null, streamChannelInitializer); assertFalse(record.acquireStream(null)); }
