Question

正如标题所述,我期待着就如何适当测试控制员的延伸方向。延期导致部分观点,而Im则使用JSONResult:

 public static string RenderPartialViewToString(this Controller controller, string viewName = null, object model = null)
        {
            if (string.IsNullOrEmpty(viewName))
            {
                viewName = controller.ControllerContext.RouteData.GetRequiredString("action");
            }

            controller.ViewData.Model = model;

            using (StringWriter sw = new StringWriter())
            {
                ViewEngineResult viewResult = ViewEngines.Engines.FindPartialView(controller.ControllerContext, viewName);
                ViewContext viewContext = new ViewContext(controller.ControllerContext, viewResult.View, controller.ViewData, controller.TempData, sw);
                viewResult.View.Render(viewContext, sw);
                return sw.GetStringBuilder().ToString();
            }
        }

例常使用:

public JsonResult Foo()
{
    var model = _repository.getSomeData();

    return Json(new { html = this.RenderPartialViewToString("Index", model) }, JsonRequestBehavior.AllowGet);
}

I m using NUnit & the MvcContrib test helper,然而,在设置一名控制器时,利用这一延伸Im 进入NRE。我假定控制者的背景没有正确确定?

归根结底,测试是在<代码>上进行的。 ViewEngines.Engines.Find PartialView。这里是失败测试的一部分:

var routeData = new RouteData();
routeData.Values.Add("controller", "someName");
routeData.Values.Add("action", "someAction");

var builder = new TestControllerBuilder();
var controller = new ListingController(repository.Object);
builder.RouteData = routeData;
builder.InitializeController(controller);

var result = controller.Foo();

页: 1 发动机收集,以便你能够模拟FindPartialView。例如,Rhino Mocks:

var view = MockRepository.GenerateStub<IView>();
var engine = MockRepository.GenerateStub<IViewEngine>();
var viewEngineResult = new ViewEngineResult(view, engine);
engine
    .Stub(x => x.FindPartialView(null, null, false))
    .IgnoreArguments()
    .Return(viewEngineResult);
ViewEngines.Engines.Add(engine);

Then you could assert that the view.Render method was called, intercept its arguments and write some mocked data to this writer and finally assert that your controller action returned this mocked string.
