Question

我如何模拟我的会员提供商（我有自定义会员资格提供商，但不知道如何模拟它并将会员资格作为提供者提供为Membership.Provider只有getter）并使用该模拟的自定义成员资格提供者我的单元测试？

这是我的控制器

public class MyController
 {   
        private IMyRepository myRepository;

        public MyController(IMyRepository myRepository) 
        {
            this.myRepository= myRepository;
        }    

       [HttpGet]
        public ActionResult Create()
        {
            var user = Membership.GetUser(); // <--- I want mock this method
            ViewBag.User = user;
            return View("Create");
        }
}

这是我的测试（使用Moq）

 [TestClass]
    public class MyControllerUnitTest
    {
        private MyController controller;

        public MyControllerUnitTest()
        {
            Mock<IMyRepository > myRepository = new Mock<IMyRepository>();
            var controller = new GroupController(myRepository.Object);
        }

        [TestMethod]
        public void TestMethod1()
        {
            var result = controller.Create() as ViewResult;
            Assert.AreEqual("Create", result.ViewName);
        }
    }

@Sergey是对的，你不应该直接使用Membership类。我知道在某些情况下您需要使用会员级别，因此添加以下信息。

您需要在类（从接口派生）中包装Membership类，然后您可以在需要的地方进行模拟。

缩短我们所获得的版本：

public interface IMembershipService
{
    MembershipUser GetUserDetails(string emailAddress);
    void CreateUserRole(string roleName);
    void AssignUserToRole(string username, string roleName);
    bool ValidateUserCredentials(string username, string password);
    void SetAuthenticationCookie(string username, bool rememberMe);
    void SignOut();
    void UpdateUser(MembershipUser membershipUser);
    bool DeleteUser(string username);
}

    public class MembershipService : IMembershipService
    {
        public MembershipUser GetUserDetails(string emailAddress)
        {
            return Membership.GetUser(emailAddress);
        }

        public MembershipUser GetUserDetails(Guid membershipId)
        {
            return Membership.GetUser(membershipId);
        }
   }

在你的控制器中，只需注入它：

public class AdminController : Controller
{
    private readonly IMembershipService _membershipService;
    private readonly IEmailService _emailService;

    public AdminController(IMembershipService membershipService, 
        IEmailService emailService)
    {
        _membershipService = membershipService;
        _emailService = emailService;
    }
}

在单元测试中，你可以这样做：

    var membershipService = new Mock<IMembershipService>();

首先，您应该从MyController类继承System.Web.Mvc.Controller：

public class MyController : System.Web.Mvc.Controller

然后你应该避免使用Membership。它是静态的，并非设计为可单元测试。更好的选择是使用控制器的User属性：

[HttpGet]
public ActionResult Index()
{
  ViewBag.UserName = this.User.Identity.Name;
  return View("Index");
}

可以使用controller.User：

模拟ControllerContext属性

  // arrange
  Mock<HttpContextBase> httpContext = new Mock<HttpContextBase>();
  httpContext.SetupGet(c => c.User.Identity.Name).Returns("John Doe");

  Mock<ControllerBase> baseControler = new Mock<ControllerBase>();

  this.controller.ControllerContext =
    new ControllerContext(httpContext.Object, new RouteData(), baseControler.Object);

  // act
  var result = this.controller.Index();

  // assert
  Assert.AreEqual("John Doe", ((ViewResult)result).ViewBag.UserName);
