the class BaseLoadBalanceTest method init.

@BeforeClass
public void init() {
    // 初始化节点
    Mockit.setUpMock(ArbitrateConfigUtils.class, new Object() {

        @Mock
        public Channel getChannel(Long pipelineId) {
            Channel channel = new Channel();
            channel.setId(channelId);
            return channel;
        }

        @Mock
        public Long getCurrentNid() {
            return 1L;
        }
    });
    node1.setId(1L);
    node2.setId(2L);
    node3.setId(3L);
    node4.setId(4L);
    zookeeper = getZookeeper();
