第12天:中断依赖

今天的重构我觉得没有太大用处

旧的代码

    public class AnimalFeedingService
    {
        private bool FoodBowlEmpty { get; set; }
        public void Feed()
        {
            if (FoodBowlEmpty)
                Feeder.ReplenishFood();
            // more code to feed the animal
        }
    }
    public static class Feeder
    {
        public static void ReplenishFood()
        {
            // fill up bowl
        }
    }

重构后的代码:

    public class AnimalFeedingService
    {
        public IFeederService FeederService { get; set; }
        public AnimalFeedingService(IFeederService feederService)
        {
            FeederService = feederService;
        }
        private bool FoodBowlEmpty { get; set; }
        public void Feed()
        {
            if (FoodBowlEmpty)
                FeederService.ReplenishFood();
            // more code to feed the animal
        }
    }
    public interface IFeederService
    {
        void ReplenishFood();
    }
    public class FeederService : IFeederService
    {
        public void ReplenishFood()
        {
            Feeder.ReplenishFood();
        }
    }
    public static class Feeder
    {
        public static void ReplenishFood()
        {
            // fill up bowl
        }
    }

 

该重构主要用来单元测试时模拟静态类
