单元测试MVC4响应状态代码

Question

我有一个单元测试，测试的路由段数太多，但我想扩展它来测试Response Status Code（应该返回404代码）。

是否有可能使用模拟的httpContext并检查状态码？

HttpContextMock.Object.Response.StatusCode返回0（由于嘲笑我想的HttpContext的一部分）。

[TestMethod] 
     public void RouteWithTooManySegments() 
     { 
      var routes = new RouteCollection(); 
      MyApp.RouteConfig.RegisterRoutes(routes); 

      var httpContextMock = new Mock<HttpContextBase>(); 
      var httpResponseMock = new Mock<HttpResponseBase>(); 

      httpContextMock.Setup(c => c.Request.AppRelativeCurrentExecutionFilePath) 
       .Returns("~/dawd/dawdaw/dawdaw/daw"); 

      RouteData routeData = routes.GetRouteData(httpContextMock.Object); 

      Assert.IsNull(routeData); 
     } 

使用ErrorController返回 “404” 的观点和适当Response Status Code：

public class ErrorController : Controller 
{ 
    public ActionResult Index() 
    { 
     return View(); 
    } 

    public ActionResult NotFound() 
    { 
     Response.StatusCode = 404; 
     return View(); 
    } 
} 

和Web.Config规则

<httpErrors errorMode="Custom" existingResponse="Replace"> 
    <remove statusCode="404" /> 
    <error statusCode="404" responseMode="ExecuteURL" path="/Error/NotFound" /> 
</httpErrors>

下面的单元测试将验证HttpStatusCode将设置为404 请注意，它必须在您的问题中设置在Controller的Action中。如果您期望Web.config进行交互，那么它更像是Web集成测试，这完全是一种不同的测试。

[TestMethod] 
public void RouteWithTooManySegments() 
{ 
    var httpContextStub = new Mock<HttpContextBase>(); 
    var httpResponseMock = new Mock<HttpResponseBase>(); 
    var controllerContextStub = new Mock<ControllerContext>(); 

    httpContextStub.Setup(x => x.Response).Returns(httpResponseMock.Object); 
    controllerContextStub.Setup(x => x.HttpContext) 
     .Returns(httpContextStub.Object); 

    var sut = new ErrorController 
     { ControllerContext = controllerContextStub.Object }; 

    sut.NotFound(); 

    httpResponseMock.VerifySet(x => x.StatusCode = 404); 
}
