Question

我试图对与this.HttpContext.Authentication直接交互的MVC 6控制器进行单元测试以进行身份验证。我没有使用Identity Framework，而是直接与Cookie身份验证中间件进行交互。

我已经看过MS的一些例子，我一直在使用DefaultHttpContext进行测试。问题是DefaultHttpContext上的AuthenticationManager属性是只读的，因此我不确定如何模拟它。

如果我不嘲笑它，我会收到错误声明＆＃34;没有配置身份验证处理程序来处理该方案：Cookies＆＃34;在我的测试中呼叫：

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

Answer 1

我遇到了同样的问题，我终于做了一些嘲弄我用Moq

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
  };

MS建议不要使用AuthenticationManager而是使用扩展方法，不推荐接受答案。另一种选择如下。请注意，添加的其他两个服务是因为设置RequestServices会删除一些默认值，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

这是使用FakeItEasy的方式：

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;

如何在MVC 6中存根/模拟AuthenticationManager？
