Question

在MVC4中，我使用Ninject注入Controller，我想测试“索引”。写入注射（注射控制器）：

public class NinjectDependencyResolver : IDependencyResolver
{ 
    private IKernel kernel;

    public NinjectDependencyResolver()
    {
        kernel = new StandardKernel();
        AddBindings();
    }

    private void AddBindings()
    { 
        kernel.Bind<IDB>().To<DB>();
    }

    public object GetService(Type serviceType)
    {
        return kernel.TryGet(serviceType);
    }

    public IEnumerable<object> GetServices(Type serviceType)
    {
        return kernel.GetAll(serviceType);
    } 
}

IDB：

public interface IDB
{
    IBugTrackRepository iBugTrackRepository { get; }
    ICategoryRepository iCategoryRepository { get; } 
    ...
    ...
    IUserRepository iUserRepository { get; }
}

实现：

public class DB : IDB
{    
    public IBugTrackRepository iBugTrackRepository
    {
        get { return new BugTrackRepository(); }
    }
    public ICategoryRepository iCategoryRepository
    {
        get { return new CategoryRepository(); }
    }
    ...
    ...
    public IUserRepository iUserRepository
    {
        get { return new UserRepository(); }
    }
}

实现：

public class BugTrackRepository : IBugTrackRepository
{
    private DBEntities context = new DBEntities ();

    public IQueryable<BugTrack> bugtrack
    {
        get { return context.BugTrack; }
    }
    ...
    //Other database operations...
}

控制器：

public class HomeController : Controller
{     
    private IDB repository; 
    public HomeController(IDB repo)
    {
        repository = repo;
    }

    public ActionResult Index()
    {
        ViewBag.mytitle = "Home Page";
        return View();
    }
}

测试代码：

    [TestMethod]
    public void TestIndex()
    {
        HomeController controller = new HomeController(??);

        ViewResult result = controller.Index() as ViewResult;

        Assert.AreEqual("Home Page", result.ViewBag.mytitle);
    }

但是这个测试是错误的，我不知道如何实例化这个Controller。请帮助我！有任何问题请留言。

您的Home的构造函数包含IDB接口，因此您需要将其传递给那里。

由于您有界面，您可以使用模拟对象（https://stackoverflow.com/questions/37359/what-c-sharp-mocking-framework-to-use）来模仿您的IDB。

如何测试指数？
