Hi , I have this method :

C#

public static IEnumerable<W_H59MpxSessionFrais> ListeSessionFrais(MpxFraisContext db, int siteID, int stval, string codeFrais)
       {
           var sessionfrais = (from D1 in db.H59_MpxSessionFrais
                               where D1.CodeFrais == codeFrais
                               && D1.SiteId == siteID
                               && D1.StatusValidation == stval
                               select new W_H59MpxSessionFrais
                               {
                                   ID = D1.SessionFraisId,
                                   LibelleSession = D1.LibelleSession,
                                   DateDebutSession = D1.DateDebutSession,
                                   DateFinSession = D1.DateFinSession
                               });
           return sessionfrais.ToList();
       }

You can write Unittest with both database data and Mock data. If you want to create a mock layer i recommend you implement the Repository Pattern and Dependency Injection.

The below example i have demonstrate a basic unit test with basic ASP.NET MVC Unitesting framework without using Dependency Injection

C#

[TestClass]
    public class YourControllerTest
    {
        private readonly SettingsController _settingsController = null;

        public SettingsControllerTest()
        {
            _settingsController=new SettingsController();
        }

        [TestMethod]
        public void ListeSessionFraisType_Of_IEnumerable_W_H59MpxSessionFrais()
        {
            var indexModel = _settingsController.ListeSessionFrais();
            Assert.IsInstanceOfType(indexModel, typeof(IEnumerable<W_H59MpxSessionFrais>));
        }
    }

Don't pass datacontext as a parameter. Please follow the Repository pattern.It will also abstract the datacontext away from the code and can test the business logic(Repositories) alone. You will get a lot code examples from the net for Repository Pattern
Hope this helps
