I am trying to figure out a way to check the appearance of the razor displayed by the HTML in the test.
I watched posts where people asked similar questions, but every time I don’t understand. The problem I get is when the view engine tries to load the .cshtml file. It returns a null reference exception from a function.
[Test] public void GetRazorViewEngine() { var _HttpContextBaseMock = new Mock<HttpContextBase>(); var _HttpRequestMock = new Mock<HttpRequestBase>(); var _HttpResponseMock = new Mock<HttpResponseBase>(); _HttpContextBaseMock.SetupGet(x => x.Request).Returns(_HttpRequestMock.Object); _HttpContextBaseMock.SetupGet(x => x.Response).Returns(_HttpResponseMock.Object); var routeData = new RouteData(); routeData.Values.Add("controller", "Home"); routeData.Values.Add("action", "About"); var controller = new HomeController(); controller.ControllerContext = new ControllerContext( _HttpContextBaseMock.Object, routeData, controller ); controller.Url = new UrlHelper( new RequestContext(_HttpContextBaseMock.Object, routeData), new RouteCollection() ); var razorEngine = ViewEngines.Engines .Where(x => x.GetType() == typeof(System.Web.Mvc.RazorViewEngine)) .FirstOrDefault(); var path = "/Users/dan/Projects/Playground/MvcPlayground/Views/Home/About.cshtml"; var master = "/Users/dan/Projects/Playground/MvcPlayground/Views/Shared/_Layout.cshtml"; ViewEngineResult viewEngineResult = razorEngine.FindView( controller.ControllerContext, path, master, false ); }
Here is the error stack trace.
