如何在MVC 6中存根/模拟AuthenticationManager？

Question

我正在尝试对直接与this.HttpContext.Authentication身份验证进行交互的MVC 6控制器进行单元测试.我没有使用Identity Framework,而是直接与Cookie Authentication中间件交互.

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

如果我不嘲笑它,我会在调用时收到一条错误,指出"我的测试中没有配置验证处理程序来处理该方案:Cookies":

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

我遇到了同样的问题,我终于用一些嘲弄的方式做了我使用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
  };
