Question

我已经模拟了抽象类来测试类的具体方法如下。

var mock = new Mock<BaseTestController>();
mock.CallBase = true;
var ta = mock.Object;

ta.ControllerContext = new HttpControllerContext { Request = new HttpRequestMessage() };          
var owinMock = new Mock<IOwinContext>();
owinMock.Setup(o => o.Authentication.User).Returns(new ClaimsPrincipal());
owinMock.Setup(o => o.Request).Returns(new Mock<OwinRequest>().Object);
owinMock.Setup(o => o.Response).Returns(new Mock<OwinResponse>().Object);
owinMock.Setup(o => o.Environment).Returns(new Dictionary<string, object> { { "key1", 123 } });
var traceMock = new Mock<TextWriter>();
owinMock.Setup(o => o.TraceOutput).Returns(traceMock.Object);

ta.Request.SetOwinContext(owinMock.Object);
var result = await ta.ActivateDeactive("test@user.com", true);

问题：我的抽象类使用Entity Framework 6 and Asp.Net Identity UserManager and RoleManager如下

public TestUserManager UserService
{
    get
    {
        return _userService ?? Request.GetOwinContext().GetUserManager<TestUserManager>();
    }

    private set
    {
        _userService = value;
    }
}

public TestRoleManager RoleService
{
    get
    {
        return _roleService ?? Request.GetOwinContext().Get<TestRoleManager>();
    }

    private set
    {
        _roleService = value;
    }
}

我如何在上面的模拟代码中模拟TestUserManager and TestRoleManager？

我尝试了以下方法，但无法通过controllerContext将其连接起来。

var userStore = new Mock<IUserStore<TestUser>>();
var userManager = new TestUserManager(userStore.Object);

回答Aleksey L下面提出的问题。

这是TestUserManager派生UserManaer并实施的方式。

public class TestUserManager : UserManager<TestUser>
{
    public TestUserManager(IUserStore<TestUser> store)
        : base(store)
    {
    }
    public static TestUserManager Create(IdentityFactoryOptions<TestUserManager> options, IOwinContext context)
    {
        TestUserManager manager = new TestUserManager(new UserStore<TestUser>(context.Get<AuthContext>()));
        setValidationRules(manager);

        IDataProtectionProvider dataProtectionProvider = options.DataProtectionProvider;
        if (dataProtectionProvider == null)
            dataProtectionProvider = new DpapiDataProtectionProvider();
         manager.UserTokenProvider = new DataProtectorTokenProvider<TestUser>(dataProtectionProvider.Create("ASP.NET Identity")) { TokenLifespan = TimeSpan.FromDays(expiryTime) };

        return manager;
    }

    public static TestUserManager CreateLocal(AuthContext context)
    {
        TestUserManager manager = new TestUserManager(new UserStore<TestUser>(context));
        setValidationRules(manager);

        IDataProtectionProvider dataProtectionProvider = new DpapiDataProtectionProvider();
        manager.UserTokenProvider = new DataProtectorTokenProvider<TestUser>(dataProtectionProvider.Create("ASP.NET Identity"));

        return manager;
    }

    private static void setValidationRules(ApplicationUserManager manager)
    {
        manager.UserValidator = new UserValidator<TestUser>(manager)
        {
            AllowOnlyAlphanumericUserNames = false,
            RequireUniqueEmail = true
        };

        manager.PasswordValidator = new ApplicationPasswordValidator
        {
            RequiredLength = 30,
            MaximumCharacters = 30,
            RequireNonLetterOrDigit = false,
            RequireDigit = true,
            RequireLowercase = false,
            RequireUppercase = false
        };
    }
}

控制器代码

public async Task<IHttpActionResult> ActivateDeactive(string studentId, bool active)
{
    IdentityResult result;
    _accountService = new AccountMgtService(UserService, RoleService);
    result = await _accountService.ActiveDeactiveUser(userId, active);

}

不确定为什么要实施TestUserManager而不仅仅是嘲笑它。 Lat说我们在控制器中有以下代码：

var owinContext = Request.GetOwinContext();
var userManager = owinContext.GetUserManager<ApplicationUserManager>();
var applicationUser = userManager.FindById("testId");

您可以通过以下方式注入模拟用户存储：

var owinMock = new Mock<IOwinContext>();

var userStoreMock = new Mock<IUserStore<ApplicationUser>>();
userStoreMock.Setup(s => s.FindByIdAsync("testId")).ReturnsAsync(new ApplicationUser
{
    Id = "testId",
    Email = "test@email.com"
});
var applicationUserManager = new ApplicationUserManager(userStoreMock.Object);

owinMock.Setup(o => o.Get<ApplicationUserManager>(It.IsAny<string>())).Returns(applicationUserManager);

ta.Request.SetOwinContext(owinMock.Object);
