c# - Response.StatusCode 在 nunit 测试中为 null

Question

我正在编写单元测试用例。我正在尝试为此方法编写单元测试但显示错误。如何在 mvc3 框架和 rhino mock 中对该方法进行单元测试。

        public ActionResult UnderConstruction()
    {
        Response.StatusCode = (int)HttpStatusCode.TemporaryRedirect;
        ErrorModel model = new ErrorModel()
        {
            ErrorMessage = "This page is still under construction; please check back later.",
            Title = "Under Construction"
        };
        return View("Error", model);
    }

Response 为 null，而不是 Response.StatusCode。您需要模拟 HttpContextBase 和 HttpResponseBase，然后创建并分配 Controller 的 ControllerContext。

测试看起来像这样(抱歉，如果我捏造了 Rhino Mock 代码；我通常使用 Moq):

// arrange
var httpContext = MockRepository.GenerateMock<HttpContextBase>();
var request = MockRepository.GenerateMock<HttpRequestBase>();
var response = MockRepository.GenerateMock<HttpResponseBase>();

// stub both Request and Response, for good measure.
httpContext.Stub(x => x.Request).Return(request);
httpContext.Stub(x => x.Response).Return(response);           

var controller = new YourController();

// create and assign the controller context
var context = new ControllerContext(httpContext, 
                  new RouteData(), 
                  controller);
controller.ControllerContext = context;

// act
var actual = controller.UnderConstruction() as ViewResultBase;

// assert
Assert.That(actual, Is.Not.Null);
Assert.That(controller.Response.StatusCode, Is.EqualTo(HttpStatusCode.TemporaryRedirect));
// etc.
