如何從一個asp.net mvc unittest中的ViewResult獲取模型？

Question

我在單元測試中調用一個控制器動作。

ViewResult result = c.Index(null,null) as ViewResult; 

我把結果給的ViewResult，因爲這就是我回到控制器：

return View(model); 

但如何我可以在我的單元測試訪問此模型變量？

Answer 1

// Arrange 
var c = new MyController(); 

//Act 
var result = c.Index(null,null); 
var model = result.ViewData.Model; 

//Assert 
Assert("model is what you want");

Answer 2

我建議你優秀MVContrib test helper。您的測試可能是這樣的：

[TestMethod] 
public void SomeTest() 
{ 
    // arrange 
    var p1 = "foo"; 
    var p2 = "bar"; 

    // act 
    var actual = controller.Index(p1, p2); 

    // assert 
    actual 
     .AssertViewRendered() // make sure the right view has been returned 
     .WithViewData<SomeViewData>(); // make sure the view data is of correct type 
} 

您也可以斷言該模型

actual 
    .AssertViewRendered() 
    .WithViewData<SomeViewData>() 
    .SomeProp 
    .ShouldEqual("some expected value");
