c# - 如何在 Asp.Net MVC 4 中模拟 HttpContext.User.Identity.Name

Question

我在 Controller 中有使用 HttpContext

的代码

public ActionResult Index()
{

   var currentUser=HttpContext.User.Identity.Name;
   ......

}

当尝试像这样使用 NUnit 编写测试时

[Test]
public void CanDisplayRequest()
{
    //Act
    var result=  (ViewResult)_requestController.Index();

    //Assert
    Assert.IsInstanceOf<OrderRequest>(resut.Model);
}

测试将失败，因为它找不到 HttpContext

那么我如何模拟 HttpContext.Current.User.Identity.Name

我正在使用 Moq 进行模拟

您可以使用伪造的上下文和伪造的主体来初始化您的 Controller ，如下所示

var fakeHttpContext = new Mock<HttpContextBase>();
var fakeIdentity = new GenericIdentity("User");
var principal = new GenericPrincipal(fakeIdentity, null);

fakeHttpContext.Setup(t => t.User).Returns(principal);
var controllerContext = new Mock<ControllerContext>();
controllerContext.Setup(t => t.HttpContext).Returns(fakeHttpContext.Object);

_requestController = new RequestController();

//Set your controller ControllerContext with fake context
_requestController.ControllerContext = controllerContext.Object;
