### Question:
NettyHttpServiceClient implements ServiceClient { @Override public void send(Operation op) { sendRequest(op); }  static ServiceClient create(String userAgent,
            ExecutorService executor,
            ScheduledExecutorService scheduledExecutor); static ServiceClient create(String userAgent,
            ExecutorService executor,
            ScheduledExecutorService scheduledExecutor,
            ServiceHost host); @Override void start(); @Override void stop(); ServiceClient setHttpProxy(URI proxy); @Override void send(Operation op); @Override void sendRequest(Operation op); @Override void handleMaintenance(Operation op); @Override ServiceClient setPendingRequestQueueLimit(int limit); @Override int getPendingRequestQueueLimit(); @Override ServiceClient setConnectionLimitPerTag(String tag, int limit); @Override int getConnectionLimitPerTag(String tag); ServiceClient setHttp2SslContext(SslContext context); SslContext getHttp2SslContext(); @Override ServiceClient setSSLContext(SSLContext context); @Override SSLContext getSSLContext(); NettyChannelPool getChannelPool(); NettyChannelPool getHttp2ChannelPool(); NettyChannelPool getSslChannelPool(); NettyChannelContext getInUseHttp2SslContext(String tag, String host, int port); NettyChannelContext getInUseHttp2Context(String tag, String host, int port); @Override ConnectionPoolMetrics getConnectionPoolMetrics(boolean http2); @Override ConnectionPoolMetrics getConnectionPoolMetricsPerTag(String tag); int getInUseContextCount(String tag, String host, int port); void clearCookieJar(); @Override int getRequestPayloadSizeLimit(); @Override ServiceClient setRequestPayloadSizeLimit(int limit); static final int DEFAULT_CONNECTIONS_PER_HOST; static final Logger LOGGER; }### Answer:
@Test public void httpsFailure() throws Throwable { List<Service> services = this.host.doThroughputServiceStart(10, MinimalTestService.class, this.host.buildMinimalTestState(), null, null); List<URI> uris = new ArrayList<>(); for (Service s : services) { URI u = UriUtils.extendUri(this.host.getSecureUri(), s.getSelfLink()); uris.add(u); } this.host.getServiceState(null, MinimalTestServiceState.class, uris); this.host.testStart(uris.size()); for (URI u : uris) { MinimalTestServiceState body = (MinimalTestServiceState) this.host .buildMinimalTestState(); body.id = MinimalTestService.STRING_MARKER_FAIL_WITH_PLAIN_TEXT_RESPONSE; Operation put = Operation.createPatch(u).setBody(body) .setCompletion((o, e) -> { this.host.completeIteration(); }); this.host.send(put); } this.host.testWait(); }
