如何嘲笑HttpContext.User.Identity.Name在Asp.Net MVC 4 [英] How to Mock HttpContext.User.Identity.Name in Asp.Net MVC 4

问题描述

我在消耗控制器code 的HttpContext

I have code in the controller which consumes HttpContext

public ActionResult Index()
{

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

}

在试图写使用NUnit这样的测试

While trying to write test using NUnit like this

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

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

，因为它找不到会导致测试失败的HttpContext

所以，我怎么能嘲笑 HttpContext.Current.User.Identity.Name

推荐答案

您可以初始化与假校长假上下文你的控制器如下图所示。

you can initialize your controller with fake context with fake principal as shown below

        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;
