C# ASP.NET MVC Controller 单元测试

Question

我是单元测试的新手，我想知道我做的是否正确。

//Controller
public ActionResult Index()
{
    return View("../Message/Index");
}

[TestMethod]
public void MessageViewCorrectTest()
{
    var controller = new MessageController();
    var result = controller.Index() as ViewResult;
    Assert.AreEqual("../Message/Index", result.ViewName);
}

[TestMethod]
public void MessageViewInCorrectTest()
{
    var controller = new MessageController();
    var result = controller.Index() as ViewResult;
    Assert.AreNotEqual("Something/Else", result.ViewName);
}

我这样做对吗，有没有更好的方法或者这样好吗？

如有任何反馈，我们将不胜感激，在此先致谢。

这里有一个方法可以做到。您也可以根据您的模型类型进行验证

[TestMethod]
public void TestMethod2()
{
  MessageController controller = new MessageController();
  ActionResult result = controller.Index(1);
  Assert.IsInstanceOfType(result, typeof(ViewResult));
  //Since view has been asserted as ViewResult
  ViewResult viewResult = result as ViewResult;  
  if(viewResult != null)
  {      
     Assert.IsInstanceOfType(viewResult.Model, typeof(YourModelType));
    //Further Asserts for your model 
  } 
}
