如何設置模擬<的UserManager <TUser >>

如何設置Mock<UserManager<ApplicationUser>> _userManager 所以_userManager.FindByIdAsync(userId)去ApplicationDbContext，發現了被標識這樣_context.Users.SingleOrDefault(u=>u.Id == userId)用戶？如何設置模擬<的UserManager <TUser >>

我的代碼：

[TestClass] 
public class AccountControllerTest 
{ 
    private ApplicationDbContext _context; 
    private Mock<UserManager<ApplicationUser>> _userManager; 
    private IHostingEnvironment _enviroment; 
    private Referrals _referrals; 
    private Mock<IEmailSender> _emailSender; 
    private Mock<IUserNameGenerator> _userNameGenerator; 
    private Mock<IUrlHelper> _urlHelper; 
    private Mock<SignInManager<ApplicationUser>> _signInManager; 
    private TimeSpan _startTrialTime; 

    [TestInitialize] 
    public void Init() 
    { 
     _userManager = UserManagerAndDbMocker.GetMockUserManager(); 
     _context = UserManagerAndDbMocker.ContextInMemoryMocker(); 
     _enviroment = new HostingEnvironment() { EnvironmentName = "Development" }; 
     _referrals = new Referrals(_context, _userManager.Object); 
     _emailSender = new Mock<IEmailSender>(); 
     _userNameGenerator = new Mock<IUserNameGenerator>(); 
     _urlHelper = new Mock<IUrlHelper>(); 
     _signInManager = new Mock<SignInManager<ApplicationUser>>(); 

     UserManagerSetup(); 
    } 


private void UserManagerSetup() 
    { 
     _userManager.Setup(um => um.CreateAsync(
      It.IsAny<ApplicationUser>(), 
      It.IsAny<string>())) 
      .Returns(Task.FromResult(IdentityResult.Success)); 

     _userManager.Setup(um => um.ConfirmEmailAsync(
      It.IsAny<ApplicationUser>(), 
      It.IsAny<string>())) 
      .Returns(
      Task.FromResult(IdentityResult.Success)); 
     _userManager.Setup(um => um.FindByIdAsync(It.IsAny<string>())); 
}

我被困在嘲諷FindByIdAsync。我想在我測試_userManager.FindById(userId)時返回_context.Users.SingleOrDefault(u=>u.Id == userId)。

public static class UserManagerAndDbMocker 
{ 
    public static Mock<UserManager<ApplicationUser>> GetMockUserManager() 
    { 
     var userStoreMock = new Mock<IUserStore<ApplicationUser>>(); 
     return new Mock<UserManager<ApplicationUser>>(
      userStoreMock.Object, null, null, null, null, null, null, null, null); 
    } 

    public static ApplicationDbContext ContextInMemoryMocker() 
    { 
     var optionsBuilder = new DbContextOptionsBuilder<ApplicationDbContext>(); 
     optionsBuilder.UseInMemoryDatabase(); 
     var context = new ApplicationDbContext(optionsBuilder.Options); 

     return context; 
    } 

}

我該如何做到這一點？

在當前狀態下的問題是，目前還不清楚，因爲它是不完整的。閱讀[問]，然後提供[mcve]，可用於更好地理解您的問題。 – Nkosi

Hi @Jones，給我們和你的測試代碼的例子或完全粘貼它，我們將能夠幫助你走向正確的方向。回答這個意見，我會看看（順便說一句，你是否熟悉Moq圖書館？） – Juan

如果我正確理解你的問題，這應該爲你工作：

_userManager 
    .Setup(um => um.FindByIdAsync(It.IsAny<string>())) 
    .Returns((string userId) => _context.Users.SingleOrDefault(u => u.Id == userId));

的回報方法，你可以指定使用您的實際輸入參數拉姆達。

又見MOQ: Returning value that was passed into a method
