Question

我有以下内容：

        SiteViewModel testForm = new SiteViewModel
        {
            SiteID = 0,
            DateCreated = DateTime.Now,
            Name = "A",
        };

        SiteController controller = new SiteController(mockSiteRepository.Object);

        //// Act
        SiteViewModel result = controller.Edit(testForm); // This will not work because Edit is an ActionResult... but I want to get the model that comes out the end of the ActionResult

如何从ActionResult方法获取模型，以便我可以对其进行测试？

Answer 1

您必须将ActionResult投射到ViewResult。然后，您可以访问Model属性。

// Act
var result = controller.Edit(testForm);

// Assert
var viewResult = result as ViewResult;
Assert.That(viewResult, Is.Not.Null);

var model = viewResult.Model as SiteViewModel;
Assert.That(model, Is.Not.Null);

// do your other assertions.

如果您的Edit操作只返回ViewResult，那么您可以更改其方法签名以指示该操作。我不建议这样做，因为它会使你的代码更脆弱，例如，如果你想在将来改变Action的行为。
