Unit testing GoLang Sarama消费者团体嘲笑

我是新手，我也在努力模仿这个呼叫：

sarama.NewConsumerGroup（brokers，group，config）

我正在使用“验证”，我的模拟代码当前看起来如下：

type MyMockedObjectReciever struct {
    mock.Mock
    Receiver
}

func (m *MyMockedObjectReciever) mockCreateConsumer(brokers []string, group string, config *sarama.Config) (sarama.ConsumerGroup, error) {
    args := m.Called(brokers, group, config)
    return args.Get(0).(sarama.ConsumerGroup), args.Error(1)
}

// mock connection and subscribe
        wantConsumer := sarama.NewConsumerGroup
        createConsumer = c.mockCreateConsumer
        c.On("mockCreateConsumer", []string{testBrokers}, testGroup, wantConfig).Return(wantConsumer, nil).Once()

但我得到了一个错误：

--- FAIL: TestKafkaReceiver (0.00s)
    --- FAIL: TestKafkaReceiver/test_a_Kafka_receiver (0.00s)
panic: interface conversion: func([]string, string, *sarama.Config) (sarama.ConsumerGroup, error) is not sarama.ConsumerGroup: missing method Close [recovered]
    panic: interface conversion: func([]string, string, *sarama.Config) (sarama.ConsumerGroup, error) is not sarama.ConsumerGroup: missing method Close

我相信我模拟的调用是错误的，但是现在确定还有什么可以做。

您可以像下面这样编写模拟消费者，以满足consumergroup对象的要求

// Consumergroup handler
type testConsumerGroupHandler struct {
}

func (C testConsumerGroupHandler) Consume(ctx context.Context, topics []string, handler sarama.ConsumerGroupHandler) error {
    return nil
}
func (C testConsumerGroupHandler) Errors() <-chan error {
    return nil
}
func (C testConsumerGroupHandler) Close() error {
    return nil
}

//Consumergroup处理程序
类型testConsumerGroupHandler结构{
}
func（C testConsumerGroupHandler）Consume（ctx context.context，topics[]string，handler sarama.ConsumerGroupHandler）错误{
归零
}
func（C testConsumerGroupHandler）错误（）
