我正在尝试模拟UserStore的CreateAsync
方法以拥有内存中的用户存储。
public void Can_Create_User()
{
//Arrange
var dummyUser = new ApplicationUser() { UserName = "PinkWarrior", Email = "PinkWarrior@PinkWarrior.com" };
var mockStore = new Mock<IUserStore<ApplicationUser>>();
var userManager = new UserManager<ApplicationUser>(mockStore.Object);
mockStore.Setup(x => x.CreateAsync(dummyUser))
.Returns(Task.FromResult(IdentityResult.Success));
//Act
Task<IdentityResult> tt = (Task<IdentityResult>)mockStore.Object.CreateAsync(dummyUser);
var user = userManager.FindByName("PinkWarrior");
//Assert
Assert.AreEqual("PinkWarrior", user.UserName);
}
上面的user
始终为空,因为我永远不会插入它。所以我遇到的问题是如何创建userManager,这不是模拟从模拟商店返回用户的?
This answer有些相似,但在这里没有回答我的问题。
任何帮助非常感谢

您需要模拟对FindByNameAsync的调用,因为这是UserManager将调用的内容:
public void Can_Create_User()
{
//Arrange
var dummyUser = new ApplicationUser() { UserName = "PinkWarrior", Email = "PinkWarrior@PinkWarrior.com" };
var mockStore = new Mock<IUserStore<ApplicationUser>>();
var userManager = new UserManager<ApplicationUser>(mockStore.Object);
mockStore.Setup(x => x.CreateAsync(dummyUser))
.Returns(Task.FromResult(IdentityResult.Success));
mockStore.Setup(x => x.FindByNameAsync(dummyUser.UserName))
.Returns(Task.FromResult(dummyUser));
//Act
Task<IdentityResult> tt = (Task<IdentityResult>)mockStore.Object.CreateAsync(dummyUser);
var user = userManager.FindByName("PinkWarrior");
//Assert
Assert.AreEqual("PinkWarrior", user.UserName);
}
但是,我相信通过这样的测试,您正在测试Microsoft.AspNet.Identity.UserManager而不是您的代码。你所证明的是UserManager以某种方式调用你的mockStore。

从MockHelper.cs
git repo
Identity
课程
Identity GitHub repo link或Closed Issue for mocking
你应该找到有关模拟的灵感,例如
public static UserManager<TUser> TestUserManager<TUser>(IUserStore<TUser> store = null) where TUser : class
{
store = store ?? new Mock<IUserStore<TUser>>().Object;
var options = new Mock<IOptions<IdentityOptions>>();
var idOptions = new IdentityOptions();
idOptions.Lockout.AllowedForNewUsers = false;
options.Setup(o => o.Value).Returns(idOptions);
var userValidators = new List<IUserValidator<TUser>>();
var validator = new Mock<IUserValidator<TUser>>();
userValidators.Add(validator.Object);
var pwdValidators = new List<PasswordValidator<TUser>>();
pwdValidators.Add(new PasswordValidator<TUser>());
var userManager = new UserManager<TUser>(store, options.Object, new PasswordHasher<TUser>(),
userValidators, pwdValidators, new UpperInvariantLookupNormalizer(),
new IdentityErrorDescriber(), null,
new Mock<ILogger<UserManager<TUser>>>().Object,
null);
validator.Setup(v => v.ValidateAsync(userManager, It.IsAny<TUser>()))
.Returns(Task.FromResult(IdentityResult.Success)).Verifiable();
return userManager;
}
我正在使用这种方法:
private UserController BuildCoontrollerWithDatabase()
{
DbContextOptionsBuilder dbContextOptionsBuilder = new DbContextOptionsBuilder();
dbContextOptionsBuilder.UseInMemoryDatabase();
ApplicationDbContext applicationDbContext = new ApplicationDbContext( dbContextOptionsBuilder.Options);
var userStore = new UserStore<ApplicationUser>(applicationDbContext);
UserManager<ApplicationUser> userManager = TestUserManager<ApplicationUser>(userStore);
return new UserController(userManager);
}

您的模拟用户存储未正确准备。因为它是一个模拟,你不应该期望mockStore.Object.CreateAsync
会做任何事情,即它可以在任何地方添加任何东西。
您需要准备相应的&#34;阅读&#34;操作,因为很可能用户管理器将调用它。 (在模拟上设置FindByNameAsync方法以返回您需要的标识)。
在任何情况下,当您尝试测试框架类UserManager时,您尝试做的事情毫无意义。
实际上你需要的是模拟用户管理器本身,并在控制器中使用该模拟,或者在你使用该用户管理器的任何地方。
