您可以通过返回的对象转换为相应的类，而不是使用其基类（这是默认返回）测试

You can test by casting the returned object to the appropriate class, instead of using their base class (which is returned by default)

例如，要测试默认的的AccountController 你会这样是这样的：

For example, to test the default AccountController you'd so something like this:

var controller = new AccountController();
var result = controller.LogOn() as ViewResult;
var model = result.Model as LogOnModel;

Assert.IsTrue(model.RememberMe); // assuming you "pre-populated" enabled the checkbox

检查返回的对象充满了正确的数据似乎并没有不自然对我来说，还是你的意思是不同的？

Checking if the returned object is filled with the right data does not seem "unnatural" to me, or did you meant it differently?
