I have an MVC 4 application that I'm building unit tests for. In my GameController, I have an Action, JoinGame, that requires the current userid. I get this with WebSecurity.CurrentUserId inside the controller.
When I run the unit test for JoinGame, UserId is not being populated. Obviously during a unit test there is no 'current' user. I'm trying to figure out how to mock one.
The first error I got was was System.ArgumentNullException: Value cannot be null. Parameter name; httpContext
After much searching, I found
How to mock httpcontext so that it is not null from a unit test?.
I followed the guidance in that link (created a HttpContextFactory,
which mocked httpcontext and also set the current controller context
to the mocked data). This didn't have any effect.
I then found this Mocking WebSecurity provider
I created a wrapper interface & class for websecurity, and mocked the wrapper & injected the websecuritywrapper into the gamecontroller. This solved the httpContext (though I presently don't really understand why this worked and the HttpContextFactory didn't), however the CurrentUserId returned by the websecuritywrapper is always 0. Even if I hardcode it to 1 insider the websecuritywrapper class (public int CurrentUserId{ get { return 1; }}
Obviously I'm doing something wrong, just not sure what. I've posted code for the unit test, the controller and the wrapper below.
public RedirectToRouteResult JoinGame(int gameid)
{
//_wr is the websecuritywrapper
int UserID = _wr.CurrentUserId; //WebSecurity.CurrentUserId;
// get userteam for this user and this game
UserTeam ut = _UserTeamRepository.GetUserTeam(userteamid:0, gameid: gameid, userid: UserID);
int intUTID = 0;
if (ut == null)
{
// no userteam found, create it
OperationStatus opStatus = _UserTeamRepository.CreateUserTeam(UserID, gameid);
if (opStatus.Status) intUTID = (int)opStatus.OperationID;
}
else {intUTID = ut.Id; }
if (intUTID > 0)
{
return RedirectToAction("Index", "ViewPlayers", new { id = intUTID });
}
else
{
return RedirectToAction("Index", "Game");
}
}

The reason that you're getting 0 back when you hard code 1 is because of this line:
Mock<IWebSecurityWrapper> mockWSW = new Mock<IWebSecurityWrapper>();
The version of the IWebSecurityWrapper you're getting is a mock (since you injected it as such). Adding
mockSW.Setup(x=>x.CurrentUserId).Returns(1);
Should get you what you need. Since we're now telling the mock to return 1 when asked for the CurrentUserId
The reason HttpContextFactory didn't work is because the HttpContextFactory implementations I've seen deal with properties on the controller and I suspect your dependency on HttpContext was inside the WebSecurity class itself, hence why you need the wrapper.

--- How can I create multi tables in one controller ?
Looks like you are using Sqlite.net-pcl, right?
Multiple tables from the same model are not supported (it's for simple cases only).
You can create multiple models (possibly by just inheriting) and then call CreatTable<T> for each of them.
I solved problem. Maybe this solution helps somenone.
I have two DbHepler Class and two model class for creating two tables on DB.
Base connection codes are same;
public interface ISQLite
{
SQLiteConnection GetConnection();
}
This is the App.cs file;
public class App : Application {
public App()
{
authenticationDB = new AuthenticationDbHelper(Database);
settingsDbHelper = new SettingsDbHelper(Database);
MainPage = new Views.MainMenuPage();
}
public static CreateDB Database
{
get
{
if (database == null)
{
database = new CreateDB();
}
return database;
}
}
}
The CreateDB class is necessary for create one db for all tables
public class CreateDB
{
public SQLiteConnection database;
public object locker = new object();
public CreateDB()
{
database = DependencyService.Get<ISQLite>().GetConnection();
}
}
This interface is necessary for created tables actions. Since implement this class we can use theese methods all tables.(T is table class)(To understand look AuthenticationDBHelper class)
public interface SQLiteBase<T>
{
IEnumerable<T> GetItems();
T GetItem(long id);
long SaveItem(T item);
void UpdateItem(T item);
int DeleteItem(int id);
int Clear();
int getCount();
}
This DbHelper class will be used for delete,insert,clear.... items.
public class AuthenticationDbHelper : SQLiteBase<AuthenticationDbTable>
{
SQLiteConnection database;
object locker;
public AuthenticationDbHelper(CreateDB db)
{
database = db.database;
locker = db.locker;
database.CreateTable<AuthenticationDbTable>();
}
public int Clear()
{
lock(locker)
{
return database.DeleteAll<AuthenticationDbTable>();
}
}
public int DeleteItem(int id)
{
lock (locker)
{
return database.Delete<AuthenticationDbTable>(id);
}
}
public AuthenticationDbTable GetItem(long id)
{
lock (locker)
{
return database.Table<AuthenticationDbTable>().FirstOrDefault(x => x.UserId == id);
}
}
public IEnumerable<AuthenticationDbTable> GetItems()
{
lock (locker)
{
return (from i in database.Table<AuthenticationDbTable>() select i).ToList();
}
}
public long SaveItem(AuthenticationDbTable item)
{
lock (locker)
{
return database.Insert(item);
}
}
public void UpdateItem(AuthenticationDbTable item)
{
lock(locker)
{
database.Update(item);
}
}
public int getCount()
{
return GetItems().Count();
}
}
I know it is very confused but this is the last. We will create model for authentication.
public class AuthenticationDbTable
{
public AuthenticationDbTable(long userId, string sessionId, string username, string clientuuid)
{
this.userId = userId;
this.sessionId = sessionId;
this.username = username;
this.clientuuid = clientuuid;
}
private long userId;
private string sessionId;
private string username;
private string clientuuid;
[PrimaryKey]
public long UserId
{
get { return userId; }
set { userId = value; }
}
public string SessionId
{
get { return sessionId; }
set { sessionId = value; }
}
public string Username
{
get { return username; }
set { username = value; }
}
public string Clientuuid
{
get { return clientuuid; }
set { clientuuid = value; }
}
}
Using
AuthenticationDbTable authentication = new AuthenticationDbTable(authenticateduser.User.UserId, r.Retval.SessionStatus.SessionId, authenticateduser.User.Name, authenticateduser.Clientuuid);
App.authenticationDB.SaveItem(authentiaction);
Note
For creating second table you can use same way. You should create second DbHelper and model class. Assume that you will create a table for settings. You should create SettingsDbHelper and SettingsDbTable class. through same way.
Thank you :)
I have an enum type field called Title.
[Serializable]
public enum Title
{
NotSet,
Miss = 4,
Mr = 1,
Mrs = 3,
Ms = 2
}
I want to bind a property of type Title to the Razor View but I don't want it to be a required field. However, on tabbing out or OnBlur, it is showing as required, although I have not specified this as required.
Is there any way I can get around this?

in your model

in your view, also add the name space to your view

hope this help you
Enums require values, and cannot be null (aka not set) despite what someone commented above. What I do for salutations is have a "none" member of the enum, and whenever I print this out, I just check in the code to see if the value of the enum is > 0 (aka, the none option) and don't print it.
public enum Salutation { none,
[Description("Mr.")] Mr,
[Description("Mrs.")] Mrs,
[Description("Ms.")]Ms,
[Description("Miss")] Miss }
Use a class rather than enum ie:
public class Title
{
NotSet;
Miss = 4;
Mr = 1;
Mrs = 3;
Ms = 2;
}
I am stuck in one of the issue. Suppose i have a phone number field 010-9999-9999, this number should split in 3 text field. I tried to do this but i get only prefix number i.e 010 in all three text field. I am using jface databinding.
I created Model as
class A{
String phoneNo;
}
Jface Databinding:
IObservableValue ssn1TextTextObserveWidget = SWTObservables.observeText(text_ph11, SWT.Modify);
IObservableValue ssn2TextTextObserveWidget = SWTObservables.observeText(text_ph2, SWT.Modify);
IObservableValue ssn2TextTextObserveWidget1 = SWTObservables.observeText(text_ph3, SWT.Modify);
IObservableValue simpleTableViewerSSN1ObserveDetailValue = BeansObservables.observeDetailValue(simpleTableViewerSelectionObserveSelection_employee, "phoneNo", String.class);
IObservableValue simpleTableViewerSSN2ObserveDetailValue = BeansObservables.observeDetailValue(simpleTableViewerSelectionObserveSelection_employee, "phoneNo", String.class);
IObservableValue simpleTableViewerSSN2ObserveDetailValue = BeansObservables.observeDetailValue(simpleTableViewerSelectionObserveSelection_employee, "phoneNo", String.class);
Databinding
bindingContext.bindValue(simpleTableViewerSSN1ObserveDetailValue, ssn1TextTextObserveWidget, null, null);
bindingContext.bindValue(simpleTableViewerSSN2ObserveDetailValue, ssn2TextTextObserveWidget, null, null);
bindingContext.bindValue(simpleTableViewerSSN2ObserveDetailValue, ssn2TextTextObserveWidget1, null, null);
When i try to do this value only prefix get populated in all three fields i.e 010-010-010. Please help me out to resolve this issue.
If you want your phone number to be divided into three different widgets you will probably need to save the phone number in three different attributes, each assigned a different part of the phone number.
There might be some way to bind a 'part' of a string value to a widget, maybe through getter methods, but for that wait and let someone more knowledgeable in this area give an answer for you.
Here is sample code that can be modified to work with your case. IConverter is used with UpdateValueStrategy to modify the value that will be set/get model to/from target text feild.

I'm trying to write custom authentication domain service. I think I understood all code which was written on this blog.
However I don't know how to specify which domain service application should use. I have one abstract domain service and second one is a concrete implementation of this service. If I build entire solution I get an error
'MainModule.Web.FormsAuthenticationService`1' is not a valid DomainService type. DomainService types cannot be abstract or generic.
I didn't find source code on blog which I mentioned before.
namespace MainModule.Web
{
using System;
using System.ServiceModel.DomainServices.Hosting;
using System.ServiceModel.DomainServices.Server;
// TODO: Create methods containing your application logic.
[EnableClientAccess()]
public abstract class FormsAuthenticationService<TUser> : DomainService, IAuthentication<TUser> where TUser : UserBase
{
protected abstract TUser GetCurrentUser(string name, string userData);
protected abstract TUser ValidateCredentials(string name, string password, string customData, out string userData);
protected virtual TUser GetDefaultUser()
{
return null;
}
public TUser GetUser()
{
IPrincipal currentUser = ServiceContext.User;
if ((currentUser != null) && currentUser.Identity.IsAuthenticated)
{
FormsIdentity userIdentity = currentUser.Identity as FormsIdentity;
if (userIdentity != null)
{
FormsAuthenticationTicket ticket = userIdentity.Ticket;
if (ticket != null)
{
return GetCurrentUser(currentUser.Identity.Name, ticket.UserData);
}
}
}
return GetDefaultUser();
}
public TUser Login(string userName, string password, bool isPersistent, string customData)
{
string userData;
TUser user = ValidateCredentials(userName, password, customData, out userData);
if (user != null)
{
FormsAuthenticationTicket ticket = new FormsAuthenticationTicket(/* version */ 1, userName,
DateTime.Now, DateTime.Now.AddMinutes(30),
isPersistent,
userData,
FormsAuthentication.FormsCookiePath);
string encryptedTicket = FormsAuthentication.Encrypt(ticket);
HttpCookie authCookie = new HttpCookie(FormsAuthentication.FormsCookieName, encryptedTicket);
HttpContextBase httpContext = (HttpContextBase)ServiceContext.GetService(typeof(HttpContextBase));
httpContext.Response.Cookies.Add(authCookie);
}
else
{
HttpContextBase httpContext = (HttpContextBase)ServiceContext.GetService(typeof(HttpContextBase));
httpContext.AddError(new FormsAuthenticationLogonException("Username or password is not correct."));
}
return user;
}
public TUser Logout()
{
FormsAuthentication.SignOut();
return GetDefaultUser();
}
public void UpdateUser(TUser user)
{
throw new NotImplementedException();
}
}
}
namespace MainModule.Web
{
using System.ServiceModel.DomainServices.Hosting;
// TODO: Create methods containing your application logic.
[EnableClientAccess()]
public class CustomAuthenticationService :FormsAuthenticationService<UserDTO>
{
protected override UserDTO GetCurrentUser(string name, string userData)
{
return new UserDTO {DisplayName = name, Name = name};
}
protected override UserDTO ValidateCredentials(string name, string password, string customData, out string userData)
{
userData = null;
UserDTO user = null;
if(name=="John" && password = "123")
{
userData = name;
user = new UserDTO {DisplayName = name, Email = "asdf"};
}
retrurn user;
}
}
}
This are classes I implemeted - it's the same code which is posted on blog. There is no exception so I can't paste an stackTrace. I just can't compile the solution
Make sure you are using the correct namespaces.
I noticed two small typos in the code that you pasted:
if(name=="John" && password = "123")
Should be:
if (name=="John" && password == "123")
retrurn user;
Should be:
return user;
Otherwise, it compiles without errors for me.
Create a new Web Application
Add a reference to System.ServiceModel.DomainServices.Hosting (ex. from "C:\Program Files (x86)\Microsoft SDKs\RIA Services\v1.0\Libraries\Server\System.ServiceModel.DomainServices.Hosting.dll")
Add a reference to System.ServiceModel.DomainServices.Server (ex. from "C:\Program Files (x86)\Microsoft SDKs\RIA Services\v1.0\Libraries\Server\System.ServiceModel.DomainServices.Server.dll")
Create a class called CustomAuthenticationService and insert the code below.

remove attribute [EnableClientAccess()] from the FormsAuthenticationService abstract class.
it will compile without any error
