c# – 构造函数参数不存在时的异常

单元测试时我当前收到以下错误：

Result Message:
Test method TestProject.TFStests.Check_Interface_CheckOut_Method threw exception:
System.InvalidOperationException: The type Adp.Tools.VersionControl.TfsVersionControl.TfsVcPromotionManager does not have a constructor that takes the parameters (TfsVcQaCheckoutWorker).

以下代码是我的Unity类,用于注册和解析TfsVCPromotionManager对象：

public class UnityClass
{
    public static ITfsVcPromotionManager returnNewPromotionManager(
       VersionControlServer tfServer)
    {
        var container = new UnityContainer();

        ITfsVcQaCheckinWorker test1 = CreateUnityCheckInWorker();
        ITfsVcQaCheckoutWorker test2 = CreateUnityCheckOutWorker(tfServer);

        container.RegisterType<ITfsVcPromotionManager,TfsVcPromotionManager>(
            new InjectionConstructor(test2),new InjectionConstructor(test1));
        return container.Resolve<TfsVcPromotionManager>();
    }

    private static ITfsVcQaCheckinWorker CreateUnityCheckInWorker()
    {
        var container = new UnityContainer();

        container.RegisterType<ITfsVcQaCheckinWorker,ITfsVcQaCheckinWorker>();
        return container.Resolve<TfsVcQaCheckinWorker>();
    }

    private static ITfsVcQaCheckoutWorker CreateUnityCheckOutWorker(
        VersionControlServer passedServer)
    {
        var container = new UnityContainer();

        container.RegisterType<ITfsVcQaCheckoutWorker,TfsVcQaCheckoutWorker>(
            new InjectionConstructor(passedServer));
        return container.Resolve<TfsVcQaCheckoutWorker>();
    }
}

这是TfsVcPromotionManager类的构造函数.请注意,它明确地接受了基于ITfsVcQaCheckoutworker和ITfsVcCheckinWorker接口的实例.

private ITfsVcQaCheckoutWorker _checkOutWorker;

    private ITfsVcQaCheckinWorker _checkInWorker;

    public TfsVcPromotionManager(ITfsVcQaCheckoutWorker checkOutWorker,ITfsVcQaCheckinWorker checkInWorker)
    {
        if (checkOutWorker == null || checkInWorker == null)
        {
            throw new NullReferenceException();
        }

        _checkOutWorker = checkOutWorker;
        _checkInWorker = checkInWorker;
    }

任何人都可以告诉我我做错了什么.
