推荐答案

在我的版本的ASP.NET MVC的有控制器上没有动作方法。但是，如果你的意思是查看方法，在这里是你如何通过单元测试结果中包含了正确的模式。

In my version of ASP.NET MVC there is no Action method on Controller. However, if you meant the View method, here's how you can unit test that the result contains the correct model.

首先，如果你只从一个特定的动作返回的ViewResult，申报方法<一个href=\"http://stackoverflow.com/questions/1021568/must-asp-net-mvc-controller-methods-return-actionresult\">returning的ViewResult代替的ActionResult 。

First of all, if you only return ViewResult from a particular Action, declare the method as returning ViewResult instead of ActionResult.

作为一个例子，考虑这个指数的行动

As an example, consider this Index action

public ViewResult Index()
{
    return this.View(this.userViewModelService.GetUsers());
}

你可以得到的模型很容易，因为这

you can get to the model as easily as this

var result = sut.Index().ViewData.Model;

如果您的方法签名的返回类型代替的ActionResult的ViewResult，你需要转换它首先的ViewResult。

If your method signature's return type is ActionResult instead of ViewResult, you will need to cast it to ViewResult first.
