Fake DbContext of Entity Framework 4.1 to Test

I'm using this tutorial to Fake my DbContext and test: http://refactorthis.wordpress.com/2011/05/31/mock-faking-dbcontext-in-entity-framework-4-1-with-a-generic-repository/

But i have to change the FakeMainModuleContext implementation to use in my Controllers:

public class FakeQuestiona2011Context : IQuestiona2011Context
{
    private IDbSet<Credencial> _credencial;
    private IDbSet<Perfil> _perfil;
    private IDbSet<Apurador> _apurador;
    private IDbSet<Entrevistado> _entrevistado;
    private IDbSet<Setor> _setor;
    private IDbSet<Secretaria> _secretaria;
    private IDbSet<Pesquisa> _pesquisa;
    private IDbSet<Pergunta> _pergunta;
    private IDbSet<Resposta> _resposta;

    public IDbSet<Credencial> Credencial { get { return _credencial ?? (_credencial = new FakeDbSet<Credencial>()); } set { } }
    public IDbSet<Perfil> Perfil { get { return _perfil ?? (_perfil = new FakeDbSet<Perfil>()); } set { } }
    public IDbSet<Apurador> Apurador { get { return _apurador ?? (_apurador = new FakeDbSet<Apurador>()); } set { } }
    public IDbSet<Entrevistado> Entrevistado { get { return _entrevistado ?? (_entrevistado = new FakeDbSet<Entrevistado>()); } set { } }
    public IDbSet<Setor> Setor { get { return _setor ?? (_setor = new FakeDbSet<Setor>()); } set { } }
    public IDbSet<Secretaria> Secretaria { get { return _secretaria ?? (_secretaria = new FakeDbSet<Secretaria>()); } set { } }
    public IDbSet<Pesquisa> Pesquisa { get { return _pesquisa ?? (_pesquisa = new FakeDbSet<Pesquisa>()); } set { } }
    public IDbSet<Pergunta> Pergunta { get { return _pergunta ?? (_pergunta = new FakeDbSet<Pergunta>()); } set { } }
    public IDbSet<Resposta> Resposta { get { return _resposta ?? (_resposta = new FakeDbSet<Resposta>()); } set { } }

    public void SaveChanges()
    {
        // do nothing (probably set a variable as saved for testing)
    }
}

And my test like that:

[TestMethod]
public void IndexTest()
{
    IQuestiona2011Context fakeContext = new FakeQuestiona2011Context();
    var mockAuthenticationService = new Mock<IAuthenticationService>();

    var apuradores = new List<Apurador>
    {
        new Apurador() { Matricula = "1234", Nome = "Acaz Souza Pereira", Email = "acaz@telecom.inf.br", Ramal = "1234" },
        new Apurador() { Matricula = "4321", Nome = "Samla Souza Pereira", Email = "samla@telecom.inf.br", Ramal = "4321" },
        new Apurador() { Matricula = "4213", Nome = "Valderli Souza Pereira", Email = "valderli@telecom.inf.br", Ramal = "4213" }
    };
    apuradores.ForEach(apurador => fakeContext.Apurador.Add(apurador));

    ApuradorController apuradorController = new ApuradorController(fakeContext, mockAuthenticationService.Object);
    ActionResult actionResult = apuradorController.Index();

    Assert.IsNotNull(actionResult);
    Assert.IsInstanceOfType(actionResult, typeof(ViewResult));

    ViewResult viewResult = (ViewResult)actionResult;

    Assert.IsInstanceOfType(viewResult.ViewData.Model, typeof(IndexViewModel));

    IndexViewModel indexViewModel = (IndexViewModel)viewResult.ViewData.Model;

    Assert.AreEqual(3, indexViewModel.Apuradores.Count);
}

I'm doing it right?
