Mock Session is not working in Unit test of Controller action - asp.net-mvc

Question

I created a sample ASP.NET MVC application.The default application provided by the Visual Studio.
I created folder named Utilities and place the below 4 classes
Connection
ConnectionRepository
SecurityManager
SessionManger
Below are the code of the above classes
public class Connection
{
public string ConnectionString { get; set; }
public Connection(string connectionStr)
{
this.ConnectionString = connectionStr;
}
public User GetUser(string userId)
{
return new User() { UserId="User1",Email="User1#company.com" };
}
}
******
using LegacyHttpContext = System.Web.HttpContext;
namespace SampleNunitApplication.Utilities
{
public class ConnectionRepository
{
public Connection ConnectionData
{
get
{
Connection con;
if(Convert.ToBoolean(LegacyHttpContext.Current.Application["isSourceOffline"].ToString()))
{
con = this.RefreshConfigDataFromAppServer();
}
else
{
con = this.RefreshConfigDataFromDB();
}
return con;
}
}
public Connection RefreshConfigDataFromDB()
{
Connection dbConnection = new Utilities.Connection("DataFromSqlServer");
LegacyHttpContext.Current.Application["_connData"] = dbConnection;
return dbConnection;
}
public Connection RefreshConfigDataFromAppServer()
{
Connection appConnection = new Utilities.Connection("DataFromAppServer");
LegacyHttpContext.Current.Application["_connData"] = appConnection;
return appConnection;
}
}
}
*******
using LegacyHttpContext = System.Web.HttpContext;
namespace SampleNunitApplication.Utilities
{
public class SecurityManager
{
public static SecurityManager GetFromCache()
{
if(LegacyHttpContext.Current.Application["SecurityManager"]==null)
{
SecurityManager securityManager = new SecurityManager();
LegacyHttpContext.Current.Application["SecurityManager"] = securityManager;
return securityManager;
}
else
{
return LegacyHttpContext.Current.Application["SecurityManager"] as SecurityManager;
}
}
public User GetAuthenticatedUser(string userId)
{
ConnectionRepository connRepository = new ConnectionRepository();
Connection con = connRepository.ConnectionData;
return con.GetUser(userId);
}
}
}
*****
public class SessionManager
{
public string EmployeeId { get; set; }
public string Email { get; set; }
public static void SaveToSessionState(HttpSessionStateBase state,SessionManager sessionManager)
{
state["SessionManager"] = sessionManager;
}
public static SessionManager LoadFromSessionState(HttpSessionStateBase state)
{
if (state["SessionManager"] ==null)
{
return new SessionManager();
}
return state["SessionManager"] as SessionManager;
}
}
****In the HomeController.cs***
public ActionResult Index()
{
SessionManager authenticateUser = SessionManager.LoadFromSessionState(this.HttpContext.Session);
ValidationModel.Validate(authenticateUser.EmployeeId, this.HttpContext);
SessionManager.LoadFromSessionState(this.HttpContext.Session);
return View();
}
*******************In the Global.asax***
protected void Session_Start()
{
HttpSessionStateWrapper sessionWrapper = new HttpSessionStateWrapper(System.Web.HttpContext.Current.Session);
System.Web.HttpContext.Current.Application["isSourceOffline"] = false;
SessionManager authenticateUser = SessionManager.LoadFromSessionState(sessionWrapper);
User user = SecurityManager.GetFromCache().GetAuthenticatedUser("User1");
authenticateUser.EmployeeId = user.UserId;
authenticateUser.Email = user.Email;
SessionManager.SaveToSessionState(sessionWrapper, authenticateUser);
}
******
I created a class library project and created below mock code
[TestClass] public class UnitTest1
{
[TestMethod]
public void TestMethod1()
{
var application = new Mock<HttpApplicationStateBase>();
SecurityManager securityManager = new SecurityManager();
application.SetupGet(s => s["isSourceOffline"]).Returns(true);
application.SetupGet(s => s["SecurityManager"]).Returns(securityManager);
var context = new Mock<HttpContextBase>();
var request = new Mock<HttpRequestBase>();
var response = new Mock<HttpResponseBase>();
var session = new Mock<HttpSessionStateBase>();
var server = new Mock<HttpServerUtilityBase>();
session.Setup(s => s.SessionID).Returns(Guid.NewGuid().ToString());
context.Setup(c => c.Request).Returns(request.Object);
context.Setup(c => c.Response).Returns(response.Object);
context.Setup(c => c.Session).Returns(session.Object);
context.Setup(c => c.Application).Returns(application.Object);
context.Setup(c => c.Server).Returns(server.Object);
SessionManager authenticatedUser = new SessionManager();
authenticatedUser.EmployeeId = "TestUser";
authenticatedUser.Email = "Test#testmail.com";
SessionManager.SaveToSessionState(context.Object.Session, authenticatedUser);
HomeController objController = new HomeController();
objController.ControllerContext = new System.Web.Mvc.ControllerContext(context.Object, new RouteData(), objController);
objController.Index();
}
}
If I run the ASP.NET MVC application it works good. But when i run the test case it hits the Index method of the HomeController but SessionManager authenticateUser = SessionManager.LoadFromSessionState(this.HttpContext.Session); is not populating from the session. Properties in the authenticateUser are null.
Seems like mock session is not working please help
