如何使用Moq模拟MVC表单POST

Question

任何人都可以请告诉如何使用Moq模拟MVC表单发布？

我要的只是单元测试我的方法基于几个不同的表单帖子。

我试过谷歌这一点，并没有从上到下的指导。

感谢

编辑：添加代码

[TestMethod] 
    public void SubscriptionControllerTest() 
    { 
     var subscriptionViewModel = new SubscriptionViewModel(); 

     //HTTP REQUEST SET UP 
     var httpRequest = new Mock<HttpRequestBase>(); 

     httpRequest.Setup(r => r.Path).Returns("/Subscription/SendEmail"); 

     httpRequest.Setup(r => r.Form).Returns(delegate() 
     { 
      var nv = new NameValueCollection(); 
      nv.Add("FirstName", "John"); 
      nv.Add("LastName", "Smith"); 
      nv.Add("Email", "jsmith@host.com"); 
      nv.Add("Comments", "Comments are here..."); 
      nv.Add("ReceiveUpdates", "true"); 
      return nv; 
     }); 


     //HTTP CONTEXT SET UP 
     var httpContext = new Mock<HttpContextBase>(); 

     httpContext.Setup(c => c.Request).Returns(httpRequest.Object); 

     var subscriptionController = new Mock<SubscriptionController>(); 
     subscriptionController.Setup(s => s.HttpContext).Returns(httpContext.Object); 

     var result = subscriptionController.Object.SendEmail(subscriptionViewModel); 

     Assert.AreEqual(((ViewResult)result).ViewName, "Index"); 

    } 
} 

我有一个名为SubscriptionController控制器。 在那里，我有一个名为SendEmail的操作方法。 我希望能够使用上面的测试方法运行我的订阅/发送电子邮件。 我的看法是一个包含以下字段的表单：名字，姓氏，电子邮件，评论和复选框。 我需要嘲笑这种形式，也嘲笑我的控制器，http请求和上下文。我有点困惑，嘲笑什么和真正使用什么。谢谢你的澄清。

答：您可以通过直接在Request.Form中设置表单值来模拟表单帖子。在我嘲笑HttpRequest之前，设置表单值，然后将httpRequest对象链接到HttpContext对象。这种方法不起作用。

我发布下面的解决方案，只是比较我以前做过，你会明白。

[TestMethod] 
public void TestSendSubscriptionEmail() 
{ 
    //HTTP CONTEXT SET UP 
    var httpContext = new Mock<HttpContextBase>();   

    var routeData = new RouteData(); 
    httpContext.Setup(c => c.Request.RequestContext.RouteData).Returns(routeData); 

    httpContext.Setup(c => c.Request.Form).Returns(delegate() 
    { 
     var nv = new NameValueCollection(); 
     nv.Add("FirstName", "John"); 
     nv.Add("LastName", "Smith"); 
     nv.Add("Email", "jsmith@host.com"); 
     nv.Add("Comments", "Comments are here..."); 
     nv.Add("ReceiveUpdates", "true"); 
     return nv; 
    }); 

    httpContext.Setup(c => c.Request.Path).Returns("/Subscription/SendEmail"); 

    var subscriptionViewModel = new Mock<ISubscriptionViewModel>(); 

    subscriptionViewModel.Setup(h => h.HttpContext).Returns(httpContext.Object); 

    subscriptionViewModel.Setup(h => h.FirstName).Returns(httpContext.Object.Request.Form["FirstName"]); 
    subscriptionViewModel.Setup(h => h.LastName).Returns(httpContext.Object.Request.Form["LastName"]); 
    subscriptionViewModel.Setup(h => h.Email).Returns(httpContext.Object.Request.Form["Email"]); 
    subscriptionViewModel.Setup(h => h.Comments).Returns(httpContext.Object.Request.Form["Comments"]); 
    subscriptionViewModel.Setup(h => h.InvestmentUpdates).Returns(bool.Parse(httpContext.Object.Request.Form["ReceiveUpdates"])); 

    var subscriptionController = new SubscriptionController(subscriptionViewModel.Object); 

    var result = subscriptionController.SendEmail(subscriptionViewModel.Object); 

    Assert.AreEqual(((ViewResult)result).ViewName, "Index"); 

}
