c# - ASP.NET MVC moq returns empty list -

i'm using moq framework test mvc application. i've added generic repository , unit of work class. when run test of controller fails because mock returns empty list (size 0) though i've added 2 elements. here test:

[testmethod]         public void index()         {             var repmock = new mock<ifakultetrepository<students>>();             var students = new list<students>();             students.add(new students() { bi = "10011", ime = "pera", prezime = "peric", adresa = "ulica1", grad = "grad1"});             students.add(new students() { bi = "20011", ime = "marko", prezime = "markovic", adresa = "ulica2", grad = "grad2" });              repmock.setup(x => x.getentities()).returns(students.topagedlist(1, 5));              studentscontroller controller = new studentscontroller(repmock.object);             viewresult result = controller.index("", "test", "test", 1) viewresult;             var listresult = result.viewdata.model pagedlist<students>;             var list = listresult.tolist();              assert.areequal(2, list.count); } 

here generic repository implements generic repository interface:

public class fakultetrepository<tentity> : ifakultetrepository<tentity> tentity : class      {         internal fakultetentities context;         internal dbset<tentity> dbset;          public fakultetrepository(fakultetentities context)         {             this.context = context;             this.dbset = context.set<tentity>();         }          public virtual ienumerable<tentity> getentities()         {             return dbset.tolist();         }          public virtual tentity getentitybyid(object id)         {             return dbset.find(id);         }          public virtual tentity getentitybyid(string id)         {             return dbset.find(id);         }          public virtual tentity getentitybyid(object[] id)         {             return dbset.find(id);         }          public virtual void insertentity(tentity entity)         {             dbset.add(entity);         }          public virtual void deleteentity(object id)         {             tentity entity = dbset.find(id);             deleteentity(entity);         }          public virtual void deleteentity(tentity entity)         {             if(context.entry(entity).state == entitystate.detached)             {                 dbset.attach(entity);             }             dbset.remove(entity);         }          public virtual void updateentity(tentity entity)         {             dbset.attach(entity);             context.entry(entity).state = entitystate.modified;         }     } 

in controller have constructor initializes unit of work , sets repository:

public studentscontroller(ifakultetrepository<students> studentrepository)         {             this.unitofwork = new unitofwork();             this.unitofwork.studentsrepository = studentrepository;         } 

and here controller method i'm testing:

public actionresult index(string sortorder, string currentfilter, string search, int? page)         {             viewbag.currentsort = sortorder;             viewbag.namesortparm = string.isnullorempty(sortorder) ? "name_desc" : "";             viewbag.bisortparm = sortorder == "bi" ? "bi_desc" : "bi";             viewbag.citysortparm = sortorder == "city" ? "city_desc" : "city";              if (search != null)             {                 page = 1;             }             else             {                 search = currentfilter;             }              viewbag.currentfilter = search;               var students = s in unitofwork.studentsrepository.getentities()                            select s;              if (!string.isnullorempty(search))             {                 students = students.where(s => s.prezime.contains(search)                                        || s.ime.contains(search)                                        || s.bi.contains(search));             }              switch (sortorder)             {                 case "name_desc":                     students = students.orderbydescending(s => s.prezime);                     break;                 case "bi":                     students = students.orderby(s => s.bi);                     break;                 case "bi_desc":                     students = students.orderbydescending(s => s.bi);                     break;                 case "city":                     students = students.orderby(s => s.grad);                     break;                 case "city_desc":                     students = students.orderbydescending(s => s.grad);                     break;                 default:                     students = students.orderby(s => s.prezime);                     break;             }             int pagesize = 10;             int pagenumber = (page ?? 1);             return view("index", students.topagedlist(pagenumber, pagesize));         } 

you creating 2 students:

students.add(new students()  {      bi = "10011", ime = "pera",      prezime = "peric", adresa = "ulica1",      grad = "grad1" });  students.add(new students()  {      bi = "20011", ime = "marko",     prezime = "markovic", adresa = "ulica2",      grad = "grad2"  }); 

you calling controller method:

index(string sortorder, string currentfilter, string search, int? page) 

with these values:

result = controller.index("", "test", "test", 1) viewresult; 

in controller method apply filter results returned call getentities()

if (!string.isnullorempty(search)) {       students = students.where(s => s.prezime.contains(search)                                   || s.ime.contains(search)                                   || s.bi.contains(search));     }     

as saw above, value of search "test"

so, assuming mock has been invoked , has returned students reason seeing no values returned in unit test

have been removed filter.
