Moq用户管理器缺少IUserEmailStore

Question

我正在测试什么。

这是一个具有登录联合网关的身份服务器项目。 我没有控制这个网关，并且他们遇到问题而没有将正确的声明返回给我，我需要验证用户登录。 我希望能够测试我能处理这些错误。

例如，电子邮件声明丢失，但我无法登录用户。

我创建了一个测试，测试电子邮件声明丢失返回错误。（工作正常）

现在我试图测试事物的另一面。 如果声明实际上在那里它应该返回与返回的声明匹配的用户。

我们正在测试的方法

public static async Task<(ApplicationUser user, string provider, string providerUserUserName, IEnumerable<Claim> claims, string message)> FindUserFromExternalProvider(AuthenticateResult result, UserManager<ApplicationUser> userManager, ILogger<SegesExternalController> logger)
    {
        var externalUser = result.Principal;

        // try to determine the unique id of the external user (issued by the provider)
        var eMailClaim = externalUser.FindFirst(SegesSettingsConstants.SegesEmailClaimName);

        if(eMailClaim == null) return (null, null, null, null, $"{SegesSettingsConstants.SegesEmailClaimName} claim not found.");

        // remove the user id claim so we don't include it as an extra claim if/when we provision the user
        var claims = externalUser.Claims.ToList();
        claims.LogSegesClaims(logger);

        claims.Remove(eMailClaim);
        // Should we remove more claims
        var provider = result.Properties.Items["scheme"];
        var providerUserUserName = eMailClaim.Value;

        var user = await userManager.FindByEmailAsync(providerUserUserName);  // Test Breaks here

        return (user, provider, providerUserUserName, claims, null);
    }

测试

[Fact]
public async void Federated_login_with_email_claim_return_no_error()
    {
        // Arrange

        var principal = new ClaimsPrincipal();
        principal.AddIdentity(new ClaimsIdentity(
            new Claim[] {
                new Claim("http://schemas.xmlsoap.org/ws/2005/05/identity/claims/name", "Testbruger til André"),
                new Claim("http://schemas.microsoft.com/ws/2008/06/identity/claims/windowsaccountname", @"PROD\Salg43"),
                new Claim("http://schemas.xmlsoap.org/ws/2005/05/identity/claims/postalcode", "8200"),
                new Claim("http://schemas.xmlsoap.org/ws/2005/05/identity/claims/locality", "Aarhus N"),
                new Claim("http://schemas.xmlsoap.org/ws/2005/05/identity/claims/emailaddress", "test@email.com"),
            },
            "FakeScheme"));
        var authenticateResult = AuthenticateResult.Success(new AuthenticationTicket(principal, new AuthenticationProperties() { Items = { { "scheme", "fed" } } }, "FakeScheme"));


        var exprectUser = new ApplicationUser()
        {
            UserName = "test@email.com",
            NormalizedUserName = "TEST@EMAIL.COM",
            NormalizedEmail = "TEST@EMAIL.COM",
            Email = "test@email.com",
            Id = 123,
            EmailConfirmed = true
        };

        var mockEmailStore = new Mock<IUserEmailStore<ApplicationUser>>();
        var mockQueryableUserStore = new Mock<IQueryableUserStore<ApplicationUser>>();

        var mockUserStore = new Mock<IUserStore<ApplicationUser>>();
        mockUserStore.Setup(x => x.FindByIdAsync(exprectUser.Id.ToString(), CancellationToken.None)).ReturnsAsync(exprectUser);
        var userManager = new UserManager<ApplicationUser>(mockUserStore.Object, null, null, null,  null, null, null, null, null);


        var logger = new Logger<ExternalController>(new LoggerFactory());

        // Act
        var (user, provider, providerUserUserName, claims, errorMessage) = await AuthorizationHelpers.FindUserFromExternalProvider(authenticateResult, userManager, logger);

        // Assert
        user.ShouldNotBeNull();
    }

上面的问题。

我正在尝试用户管理器进行单元测试

var exprectUser = new ApplicationUser()
        {
            UserName = "test@email.com",
            NormalizedUserName = "TEST@EMAIL.COM",
            NormalizedEmail = "TEST@EMAIL.COM",
            Email = "test@email.com",
            Id = 123,
            EmailConfirmed = true
        };

var mockUserStore = new Mock<IUserStore<ApplicationUser>>();
mockUserStore.Setup(x => x.FindByIdAsync(exprectUser.Id.ToString(), CancellationToken.None)).ReturnsAsync(exprectUser);
var userManager = new UserManager<ApplicationUser>(mockUserStore.Object, null, null, null,  null, null, null, null, null);

但是当我测试的方法试图找到用户时。

var findUser = await userManager.FindByEmailAsync("test@test.com");

它会抛出一个错误

消息：System.NotSupportedException：Store未实现IUserEmailStore。

如何在我的moq usermanager中实现IUserEmailStore？

我的单元测试项目确实包含最新的EntityFramework包。

尝试另一种方式。

var founduser = userManager.Users.FirstOrDefault(e => e.Email.Equals("test@test.com", StringComparison.InvariantCultureIgnoreCase));

结果是

System.NotSupportedException：Store未实现IQueryableUserStore。

我想我一定是莫青这个错了。

从评论更新

好吧，我可以moq IUserEmailStore，但我不知道我应该怎么做

var mockEmailStore = new Mock<IUserEmailStore<ApplicationUser>>();

Answer 1

我设法创建了一个完整的moq用户管理器，可以让我搜索电子邮件

 public class MoqUserManager : UserManager<ApplicationUser>
    {
        public MoqUserManager(IUserStore<ApplicationUser> userStore) : base(userStore,
                new Mock<IOptions<IdentityOptions>>().Object,
                new Mock<IPasswordHasher<ApplicationUser>>().Object,
                new IUserValidator<ApplicationUser>[0],
                new IPasswordValidator<ApplicationUser>[0],
                new Mock<ILookupNormalizer>().Object,
                new Mock<IdentityErrorDescriber>().Object,
                new Mock<IServiceProvider>().Object,
                new Mock<ILogger<UserManager<ApplicationUser>>>().Object)
        { }

        public override Task<ApplicationUser> FindByEmailAsync(string email)
        {
            return Task.FromResult(new ApplicationUser { Email = email });
        }    
    }

这给了我

var mockUserStore = new Mock<IUserStore<ApplicationUser>>();
mockUserStore.Setup(x => x.FindByIdAsync(exprectUser.Id.ToString(), CancellationToken.None)).ReturnsAsync(exprectUser);
var userManager = new FakeUserManager(mockUserStore.Object);

所以现在我可以验证从匹配联合登录用户的身份服务器返回了正确的用户。

好的，问题在于更新的问题

var userManager = new UserManager<ApplicationUser>(mockUserStore.Object, null, null, null,  null, null, null, null, null);

这不是创建模拟，而是创建UserManager<T>的实际实例。

你必须这样做

var userManagerMock = new Mock<UserManager<ApplicationUser>>(mockUserStore.Object, null, null, null,  null, null, null, null, null);

然后做一个设置

userManagerMock.Setup(um => um.FindByEmailAsync("test@email.com)).Returns(exprectUser)

并将userManagerMock.Object传递给您的

var (user, provider, providerUserUserName, claims, errorMessage) = await AuthorizationHelpers.FindUserFromExternalProvider(authenticateResult, userManagerMock.Object, logger);

在模拟时，你永远不想在外部依赖项上调用new ，而是模拟它，因为那样你就无法改变它对特定测试的行为。 UserManager<T>应将所有或大多数公共属性设置为虚拟属性，以便您可以覆盖它们。
