如何解决XUnit模拟自定义身份管理器和存储,无法实例化以下类的代理:API.Identity.Managers.MyUserManager
我正在使用Moq来模拟我的AuthenticationController,初始化XUnit测试时会发生错误, 问题出在在线测试类的构造函数上:
_myUserManager = new Mock<MyUserManager<AppUser>>(_myUserStore.Object);
在此行上,尝试模拟对象时,出现Castle.DynamicProxy.InvalidProxyconstructorargumentsException类型的异常。
和messege和stacktrace在这里:
Message:
Castle.DynamicProxy.InvalidProxyconstructorargumentsException : Can not instantiate proxy of class: API.Identity.Managers.MyUserManager`1[[API.Identity.Models.AppUser,API,Version=1.0.0.0,Culture=neutral,PublicKeyToken=null]].

这是测试班
public class AuthenticateControllerTests {
private AuthenticateController _controller;
private Mock<ILoggerSevice> _loggerSevice;
private Mock<IJwtAuthService> _jwtAuthService;
private Mock<IEmailService> _emailService;
private Mock<IEmailGateway> _emailGateway;
private Mock<IValidationHelper> _validationHelper;
private Mock<IMyUserStore> _myUserStore;
private Mock<MyUserManager<AppUser>> _myUserManager;
private Mock<IMyCustomerUserStore> _myCustomerUserStore;
private Mock<MyCustomerUserManager<AppCustomerUser>> _myUserCustomerManager;
private Mock<SignInManager<AppUser>> _signInManager;
private Mock<SignInManager<AppCustomerUser>> _signInCustomerManager;
public AuthenticateControllerTests() {
//set up authenticate controller
_loggerSevice = new Mock<ILoggerSevice>();
_jwtAuthService = new Mock<IJwtAuthService>();
_emailService = new Mock<IEmailService>();
_emailGateway = new Mock<IEmailGateway>();
_validationHelper = new Mock<IValidationHelper>();
_myUserStore = new Mock<IMyUserStore>();
_myUserManager = new Mock<MyUserManager<AppUser>>(_myUserStore.Object);
_signInManager = new Mock<SignInManager<AppUser>>(_myUserManager.Object);
_myCustomerUserStore = new Mock<IMyCustomerUserStore>();
_myUserCustomerManager = new Mock<MyCustomerUserManager<AppCustomerUser>>(_myCustomerUserStore.Object);
_signInCustomerManager = new Mock<SignInManager<AppCustomerUser>>(_myUserCustomerManager.Object);
_controller = new AuthenticateController(_loggerSevice.Object,_jwtAuthService.Object,_myUserManager.Object,_myUserCustomerManager.Object,_signInManager.Object,_signInCustomerManager.Object,_emailService.Object,_validationHelper.Object,_emailGateway.Object);
}
public MyUserManager(IMyUserStore myUserStore,IOptions<IdentityOptions> optionsAccessor,IPasswordHasher<AppUser> passwordHasher,IEnumerable<IUserValidator<AppUser>> userValidators,IEnumerable<IPasswordValidator<AppUser>> passwordValidators,ILookupnormalizer keynormalizer,IdentityErrorDescriber errors,IServiceProvider services,ILogger<UserManager<AppUser>> logger) :
base(myUserStore,optionsAccessor,passwordHasher,userValidators,passwordValidators,keynormalizer,errors,services,logger) {
_myUserStore = myUserStore;
}
public interface IMyUserStore : IUserStore<AppUser>,IUserEmailStore<AppUser>,IUserPhoneNumberStore<AppUser>,IUserTwoFactorStore<AppUser>,IUserPasswordStore<AppUser>,IUserRoleStore<AppUser> {
public class MyUserStore : IMyUserStore {
private readonly IUserGateway _userGateway;
private readonly IRoleGateway _roleGateway;
解决方法
在模拟MyUserManager
之类的实现时,Moq需要一个可访问的构造函数来创建该模拟,并且您需要为所述构造函数提供参数。
所以您的构造函数是
public MyUserManager(IMyUserStore myUserStore,IOptions<IdentityOptions> optionsAccessor,IPasswordHasher<AppUser> passwordHasher,IEnumerable<IUserValidator<AppUser>> userValidators,IEnumerable<IPasswordValidator<AppUser>> passwordValidators,ILookupNormalizer keyNormalizer,IdentityErrorDescriber errors,IServiceProvider services,ILogger<UserManager<AppUser>> logger)
但是您只提供一个IMyUserStore
参数:
new Mock<MyUserManager<AppUser>>(_myUserStore.Object);
您需要提供其余的参数;或使用其他构造函数(并再次提供参数);或者如果您可以为MyUserManager
定义一个接口,还是更好,请对其进行模拟。
