Each time, like trying to send an email, I will not be sent, but it says:
An unhandled exception occurred while processing the request.
ArgumentNullException: Value cannot be null. Parameter name:
Templates/NewPassword does not match any available view
This is what it looks like when I refer to the file.
That's how I've tried to look here.Github - Paris Plyzos
Also code here:
var resultMail = await _viewRenderService.RenderToStringAsync("Templates/NewPassword", viewModel); //ERROR HERE!
var client = new SendGridClient(m.azureName());
var from = new EmailAddress(m.mailFrom(), m.nameFrom());
var to = new EmailAddress(mail, UserValue.Navn);
var plainTextContent = Regex.Replace(resultMail, "<[^>]*>", "");
var msg = MailHelper.CreateSingleEmail(from, to, title, plainTextContent: plainTextContent,
htmlContent: null);
var resulta = client.SendEmailAsync(msg);
return RedirectToAction("UserPassword");
RenderToStringAsync code here - I've written an error where the error goes wrong here.
public async Task<string> RenderToStringAsync(string viewName, object model)
{
var httpContext = new DefaultHttpContext { RequestServices = _serviceProvider };
var actionContext = new ActionContext(httpContext, new RouteData(), new ActionDescriptor());
using (var sw = new StringWriter())
{
var viewResult = _razorViewEngine.FindView(actionContext, viewName, false);//ERROR HERE
if (viewResult.View == null)
{
throw new ArgumentNullException($"{viewName} does not match any available view");
}
var viewDictionary = new ViewDataDictionary(new EmptyModelMetadataProvider(), new ModelStateDictionary())
{
Model = model
};
var viewContext = new ViewContext(actionContext, viewResult.View, viewDictionary, new TempDataDictionary(actionContext.HttpContext, _tempDataProvider),
sw,
new HtmlHelperOptions()
);
await viewResult.View.RenderAsync(viewContext);
return sw.ToString();
}
}
How is your IViewRenderService.RenderToStringAsync() implementation finding views? If you are using IRazorViewEngine, the ViewName has to be fully qualified including file extension ex "~/Views/Home/Index.cshtml"

I am currently running unit tests on a controller that utilizes Url.Action to get the absolute path of two different routes. I am using Moq to set up the mock Action. The test is currently failing with the message 'Object reference not set to an instance of an object.'
[Edit - Clarifying the question]
When I debug the test, the Url shows to as a Mock<IUrlHelper> with an ActionContext property, but on the line where it calls the Url.Action, the Action property shows as null. What am I missing when setting up the Mock<IUrlHelper> that way the Url.Action doesn't come back as null?
I've checked multiple options for setting up Mock Url Actions, but nothing has seemed to work for me.
Here is the setup for the test
[Fact]
public async void SendGroup_PassesDetailsToNotificationService()
{
UrlActionContext actualContext = null;
var criteria = new NotificationCriteria { Section = 1, Subsection = 2 };
userSvc.GetNotificationGroupReturnValue = new List<NotificationRecipient>
{
new NotificationRecipient{ SmsAuth = true }
};
var actionContext = new ActionContext
{
ActionDescriptor = new ActionDescriptor(),
RouteData = new RouteData(),
};
var urlHelper = new Mock<IUrlHelper>();
urlHelper.SetupGet(h => h.ActionContext).Returns(actionContext);
urlHelper.Setup(h => h.Action(It.IsAny<UrlActionContext>()))
.Callback((UrlActionContext context) => actualContext = context);
controller.Url = urlHelper.Object;
var dummy = await controller.SendGroup(criteria);
Assert.Same(criteria, notificationSvc.SendGroupNotificationDetailUsed);
}
This is the code for the controller
[HttpPost]
public async Task<IActionResult> SendGroup([FromBody]NotificationCriteria criteria)
{
List<NotificationRecipient> recipients = (await userSvc.GetNotificationGroup(
criteria.Section, criteria.Subsection)).ToList();
if (!recipients.Any())
{
return BadRequest();
}
var uro = Url;
var sectionUrl = Url.Action("Index", "ReportHome", new {sectionId = criteria.Section}, Request.Scheme);
var profileUrl = Url.Action("Index", "Profile", null, Request.Scheme);
var detail = new NotificationDetail
{
SectionUrl = sectionUrl,
ProfileUrl = profileUrl,
Recipients = recipients
};
try
{
await notificationSvc.SendGroupNotification(detail);
}
catch
{
return StatusCode(500);
}
return Ok();
}
I need server side page render (without request) outside controller(I want to render view outside controller).
To do that, i need a fake HttpRequest to create ControllerContext so i can render view with razor.Render() and return
stringWriter.ToString() to client using signalr hub.
So i used this code to render partialview as string;
public class FakeController : Controller { }
HttpRequest httpRequest = new HttpRequest("", new UriBuilder("http", "localhost", 10654, "/" + "SomeController/SomeAction").Uri.ToString(), "");
var routeData = new RouteData();
routeData.Values.Add("Controller", "SomeController");
routeData.Values.Add("Action", "SomeAction");
StringWriter stringWriter = new StringWriter();
HttpResponse httpResponse = new HttpResponse(stringWriter);
HttpContext httpContextMock = new HttpContext(httpRequest, httpResponse);
var _contextWrapper = new HttpContextWrapper(httpContextMock);
var controllerContext = new ControllerContext(new RequestContext(_contextWrapper , routeData), new FakeController());
string filePath = "~/Areas/Site/Views/Shared/SomePartialView.cshtml";
var razor = new RazorView(controllerContext, filePath, null, false, null);
razor.Render(new ViewContext(controllerContext, razor, new ViewDataDictionary(model), new TempDataDictionary(), stringWriter), stringWriter);
return stringWriter.ToString();
Here when code tries to render #Html.HiddenFor(m => m.property)
I get error;
source : System.Web.WebPages
error : Object reference not set to an instance of an object
But the weird thing is that i can get #Model.property value(i mean it is not null) and also the other model properties(And it seems that only #Html.HiddenFor or #Html.Hidden is the problem).
I want to create a unit test method for the below method which is receiving a file upload "text file" data and parsing it, I tried to use Moq and created a method but I am still very confused in the concept, I need a sample code, I've read many stackover flow questions but it is all for Controllers not Web API
the method used
// Enable both Get and Post so that our jquery call can send data, and get a status
[HttpGet]
[HttpPost]
public HttpResponseMessage Upload()
{
// Get a reference to the file that our jQuery sent. Even if multiple files, they will
// all be their own request and be the 0 index
if (HttpContext.Current.Request.Files.Count>0)
{
HttpPostedFile file = HttpContext.Current.Request.Files[0];
if (file != null && file.ContentLength > 0)
{
try
{
var extension = Path.GetExtension(file.FileName);
if (!IsFileFormatSupported(extension))
{
var objectSerialized = SerializeData(GetError( GlobalResources.NotSupportedFileExtension));
return BadResponse(objectSerialized);
}
var path = SaveFileGetPath(file);
var result = GetPaySlips(path);
var SerializedData = SerializeData(result);
return OkResponse(SerializedData);
}
catch (System.Exception exception)
{
var SerializedData = SerializeData(GetError( GlobalResources.CouldNotReadFile + " " + exception.Message));
return BadResponse(SerializedData);
}
}
else
{
var SerializedData = SerializeData(GetError(file.FileName + " " + GlobalResources.FileisCorrupt));
return BadResponse(SerializedData);
}
}else
{
var SerializedData = SerializeData(GetError( GlobalResources.FileisCorrupt));
return BadResponse(SerializedData);
}
}
the code I did so far
var FileUploadCtrl = new UploadController();
Mock<HttpRequestMessage> cc = new Mock<HttpRequestMessage>();
UTF8Encoding enc = new UTF8Encoding();
// Mock<HttpPostedFileBase> file1 = new Mock<HttpPostedFileBase>();
//file1.Expect(f=>f.InputStream).Returns(file1.Object.InputStream);
//cc.Expect(ctx => ctx.Content).Returns(new retur);
// cc.Expect(ctx => ctx.Content).Returns();
var content = new ByteArrayContent( /* bytes in the file */ );
content.Headers.Add("Content-Disposition", "form-data");
var controllerContext = new HttpControllerContext
{
Request = new HttpRequestMessage
{
Content = new MultipartContent { content }
}
};
//file1.Expect(d => d.FileName).Returns("FileTest.csv");
//file1.Expect(d => d.InputStream).Returns(new HttpResponseMessage(HttpStatusCode.OK)));
var config = new HttpConfiguration();
//var request = new HttpRequestMessage(HttpMethod.Post, "http://localhost/api/upload");
var route = config.Routes.MapHttpRoute("DefaultApi", "api/{controller}/{id}");
var routeData = new HttpRouteData(route, new HttpRouteValueDictionary { { "controller", "FileUpload" } });
FileUploadCtrl.ControllerContext = new HttpControllerContext(config, routeData, cc.Object);
var r = FileUploadCtrl.Upload();
Assert.IsInstanceOfType(r, typeof(HttpResponseMessage));
In my Asp.net core 1 app I have controller with following method:
[Microsoft.AspNetCore.Mvc.HttpPost()]
[Microsoft.AspNetCore.Mvc.RequireHttps]
public async System.Threading.Tasks.Task<Microsoft.AspNetCore.Mvc.IActionResult> Save()
{
if (ModelState.IsValid)
{
try
{
var pass = Request.Form["password"].ToString();
var pass1 = Request.Form["password1"].ToString();
if (!pass.Equals(pass1))
{
return View("~/Views/PasswordRecovery.cshtml");
}
}
catch (System.Exception ex)
{
return View("~/Views/Message.cshtml");
}
}
return View("~/Views/Message.cshtml");
}
I want to write a test for this method. So I have written this:
[Xunit.Fact]
public async System.Threading.Tasks.Task SavePassNotEqualTest()
{
var controller = new Controllers.PasswordRecoveryController(_mockRepo.Object);
var dic = new System.Collections.Generic.Dictionary<string, Microsoft.Extensions.Primitives.StringValues>();
dic.Add("password", "test");
dic.Add("password1", "test1");
var collection = new Microsoft.AspNetCore.Http.FormCollection(dic);
controller.Request.Form = collection; //request is null
var result = await controller.Save();
var viewResult = Xunit.Assert.IsType<Microsoft.AspNetCore.Mvc.ViewResult>(result);
Xunit.Assert.Equal("~/Views/Message.cshtml", viewResult.ViewName);
}
The problem is that I need to set some test values to Form, Form is in Request, and Request is NULL. I can not find, how can I create some not NULL request and fill it's Form with values.
EDIT
Answers helped me to finish up with following solution:
I've created a method that will return a FormCollection:
private Microsoft.AspNetCore.Http.FormCollection GetFormCollection()
{
var dic = new System.Collections.Generic.Dictionary<string, Microsoft.Extensions.Primitives.StringValues>();
dic.Add("password", "test");
dic.Add("password1", "test1");
return new Microsoft.AspNetCore.Http.FormCollection(dic);
}
And my test method is:
[Xunit.Fact]
public async System.Threading.Tasks.Task SavePassNotEqualTest()
{
var controller = new Findufix.Controllers.PasswordRecoveryController(_mockRepo.Object);
var httpContext = new Moq.Mock<Microsoft.AspNetCore.Http.HttpContext>();
httpContext.Setup( x => x.Request.Form).Returns(GetFormCollection());
controller.ControllerContext.HttpContext = httpContext.Object;
var result = await controller.Save();
var viewResult = Xunit.Assert.IsType<Microsoft.AspNetCore.Mvc.ViewResult>(result);
Xunit.Assert.Equal("~/Views/PasswordRecovery.cshtml", viewResult.ViewName);
}
If you pass a DefaultHttpContext to your controller, Request won't be null and you can assign the form to Request.Form. No mocking required.
[Xunit.Fact]
public async System.Threading.Tasks.Task SavePassNotEqualTest()
{
var controller = new Controllers.PasswordRecoveryController(_mockRepo.Object);
var dic = new System.Collections.Generic.Dictionary<string, Microsoft.Extensions.Primitives.StringValues>();
dic.Add("password", "test");
dic.Add("password1", "test1");
var collection = new Microsoft.AspNetCore.Http.FormCollection(dic);
// Give the controller an HttpContext.
controller.ControllerContext.HttpContext = new DefaultHttpContext();
// Request is not null anymore.
controller.Request.Form = collection;
var result = await controller.Save();
var viewResult = Xunit.Assert.IsType<Microsoft.AspNetCore.Mvc.ViewResult>(result);
Xunit.Assert.Equal("~/Views/Message.cshtml", viewResult.ViewName);
}
With Moq, you can do it like this:
var httpContext = new Mock<HttpContextBase>();
httpContext.Setup(c => c.Request.Form).Returns(delegate()
{
var formVaues = new NameValueCollection();
formVaues .Add("Id", "123");
formVaues .Add("Name", "Smith");
return formVaues ;
});
In Moq you can try to use Setup() or SetupGet() to teach it to return something that you need
something along the lines of
controller.SetupGet(x => x.Request.Form).Returns(collection);
I have a working application for which I need to now add a full set of unit tests. The current code stores the user information as follows:
HttpContext.Current.Session["UserInfo"] = userData;
I'm using moq for my testing, and my unit test has the following code:
var server = new Mock<HttpServerUtilityBase>(MockBehavior.Loose);
var response = new Mock<HttpResponseBase>(MockBehavior.Strict);
var request = new Mock<HttpRequestBase>(MockBehavior.Strict);
var context = new Mock<HttpContextBase>();
context.SetupGet(x => x.Request).Returns(request.Object);
context.SetupGet(x => x.Response).Returns(response.Object);
context.SetupGet(x => x.Server).Returns(server.Object);
var controller = new LoginController();
controller.ControllerContext = new ControllerContext(
context.Object,
new RouteData(),
controller);
JsonResult result = controller.LoginUser(
new LoginHelper {
userName = "myusername",
password = "invalidpassword"
}
) as JsonResult;
Of course when I get to where the login process tries to create the session data, I get an "Object reference not set to an instance of an object." error becuase HttpContext.Current is null.
Some research has shown me that using Current isn't exactly compatible with MSTest, so I understand that I might need to change the way I store/load my user information. However, I would like some advice on which way to go here.
I would appreciate any suggestions on either how to get my unit tests to work, or a different method to store the user info to make it more compatible with unit tests.
This was the solution I came up with. It is a combination of a few things I found in various places including here:
First, I created 2 classes .. MockHttpSession, and MockHelpers
public class MockHttpSession : HttpSessionStateBase
{
Dictionary<string, object> m_SessionStorage = new Dictionary<string, object>();
public override object this[string name]
{
get { return m_SessionStorage[name]; }
set { m_SessionStorage[name] = value; }
}
public override void Abandon()
{
// Do nothing
}
}
public class MockHelpers
{
public static HttpContext FakeHttpContext()
{
var httpRequest = new HttpRequest("", "http://localhost/", "");
var stringWriter = new StringWriter();
var httpResponse = new HttpResponse(stringWriter);
var httpContext = new HttpContext(httpRequest, httpResponse);
var sessionContainer = new HttpSessionStateContainer(
"id",
new SessionStateItemCollection(),
new HttpStaticObjectsCollection(),
10,
true,
HttpCookieMode.AutoDetect,
SessionStateMode.InProc,
false);
SessionStateUtility.AddHttpSessionStateToContext(httpContext, sessionContainer);
return httpContext;
}
}
Then I changed my unit test code to use these:
var server = new Mock<HttpServerUtilityBase>(MockBehavior.Loose);
var response = new Mock<HttpResponseBase>(MockBehavior.Strict);
var request = new Mock<HttpRequestBase>(MockBehavior.Strict);
var session = new MockHttpSession();
var context = new Mock<HttpContextBase>();
context.SetupGet(x => x.Request).Returns(request.Object);
context.SetupGet(x => x.Response).Returns(response.Object);
context.SetupGet(x => x.Server).Returns(server.Object);
context.SetupGet(x => x.Session).Returns(session);
HttpContext.Current = MockHelpers.FakeHttpContext();
var controller = new LoginController();
controller.ControllerContext = new ControllerContext(context.Object, new RouteData(), controller);
JsonResult result = controller.LoginUser(new LoginHelper { userName = "MyUserName", password = ""InvalidPassword }) as JsonResult;
This was able to successfully test the code with both valid and invalid passwords.
Thanks everyone for your help
