我如何在 MVC 6 中 stub/mock AuthenticationManager？

Question

我正在尝试对直接与 this.HttpContext.Authentication 交互以进行身份验证的 MVC 6 控制器进行单元测试。我没有使用身份框架，而是直接与 Cookie 身份验证中间件交互。

根据我在 MS 看到的一些示例，我一直在使用 DefaultHttpContext 进行测试。问题是 DefaultHttpContext 上的 AuthenticationManager 属性是只读的，所以我不确定如何模拟它。

如果我不模拟它，我会在调用时收到一条错误消息，指出 "No authentication handler is configured to handle the scheme: Cookies" 在我的测试中：

HttpContext.Authentication.SignInAsync(CookieAuthenticationDefaults.AuthenticationScheme, claimsPrincipal, authProperties);

Answer 1

我遇到了同样的问题，我终于通过某种程度的模拟解决了我用起订量

var claimPrincipal = new ClaimsPrincipal();

var mockAuth = new Mock<AuthenticationManager>();
mockAuth.Setup(c => c.SignInAsync("YourScheme", claimPrincipal)).Returns(Task.FromResult("done"));

var mockContext = new Mock<HttpContext>();
            mockContext.Setup(c => c.Authentication).Returns(mockAuth.Object);

var fakeActionContext = new ActionContext(mockContext.Object, new RouteData(), new ControllerActionDescriptor());
var contContext = new ControllerContext(fakeActionContext);

然后将该控制器上下文传递给您要测试的控制器

 var controller = new TestedController(Your attribute)
 {
       ControllerContext = contContext
  };

微软现在弃用了接受的答案，微软建议不要使用 AuthenticationManager 而是使用扩展方法。下面是一个替代方案。请注意，添加的另外两个服务是因为设置 RequestServices 删除了一些默认值，否则这些默认值将由 DefaultHttpContext 创建。

var context = new ControllerContext();
context.HttpContext = new DefaultHttpContext();
context.HttpContext.User = userMock.Object;  // If needed
context.HttpContext.Session = sessionMock.Object;  // If needed

var authManager = new Mock<IAuthenticationService>();
authManager.Setup(s => s.SignOutAsync(It.IsAny<HttpContext>(), 
            CookieAuthenticationDefaults.AuthenticationScheme, 
            It.IsAny<Microsoft.AspNetCore.Authentication.AuthenticationProperties>())).
            Returns(Task.FromResult(true));
var servicesMock = new Mock<IServiceProvider>();
servicesMock.Setup(sp => sp.GetService(typeof(IAuthenticationService))).Returns(authManager.Object);
servicesMock.Setup(sp => sp.GetService(typeof(IUrlHelperFactory))).Returns(new UrlHelperFactory());
servicesMock.Setup(sp => sp.GetService(typeof(ITempDataDictionaryFactory))).Returns(new TempDataDictionaryFactory(new SessionStateTempDataProvider()));

context.HttpContext.RequestServices = servicesMock.Object;
// Use context to pass to your controller

这就是使用 FakeItEasy 的方法：

var actionContext = new ActionContext
        {
            HttpContext = new DefaultHttpContext(),
            RouteData = new RouteData(),
            ActionDescriptor = new ControllerActionDescriptor()
        };

// Creating AuthenticationService and Return calls for the Authentication factory
            var authManager = A.Fake<IAuthenticationService>();
            var authProperties = new Microsoft.AspNetCore.Authentication.AuthenticationProperties();
            var servicesMock = A.Fake<IServiceProvider>();
            A.CallTo(() => authManager.SignOutAsync(actionContext.HttpContext, CookieAuthenticationDefaults.AuthenticationScheme, authProperties)).Returns(Task.FromResult(true));
            A.CallTo(() => servicesMock.GetService(typeof(IAuthenticationService))).Returns(authManager);
            A.CallTo(() => servicesMock.GetService(typeof(IUrlHelperFactory))).Returns(new UrlHelperFactory());
            A.CallTo(() => servicesMock.GetService(typeof(ITempDataDictionaryFactory))).Returns(new TempDataDictionaryFactory(new SessionStateTempDataProvider()));

            var concon = new ControllerContext(actionContext);
            concon.HttpContext.RequestServices = servicesMock;
