### Question:
CronetClientTransport implements ConnectionClientTransport { @Override public Attributes getAttributes() { return attrs; } CronetClientTransport(
      StreamBuilderFactory streamFactory,
      InetSocketAddress address,
      String authority,
      @Nullable String userAgent,
      Executor executor,
      int maxMessageSize,
      boolean alwaysUsePut,
      TransportTracer transportTracer); @Override ListenableFuture<SocketStats> getStats(); @Override CronetClientStream newStream(final MethodDescriptor<?, ?> method, final Metadata headers,
      final CallOptions callOptions); @Override Runnable start(Listener listener); @Override String toString(); void shutdown(); @Override void shutdown(Status status); @Override void shutdownNow(Status status); @Override Attributes getAttributes(); @Override void ping(final PingCallback callback, Executor executor); @Override InternalLogId getLogId();  }### Answer:
@Test public void transportAttributes() { Attributes attrs = transport.getAttributes(); assertEquals( SecurityLevel.PRIVACY_AND_INTEGRITY, attrs.get(GrpcAttributes.ATTR_SECURITY_LEVEL)); }
