for unit testing (moq) how to set up repository which takes DbContext as a constructor.

my repository implementation looks something like this

     public class EFRepository<T> : IRepository<T> where T : class
{
    public EFRepository(DbContext dbContext)
    {
        if (dbContext == null)
            throw new ArgumentNullException("dbContext");
        DbContext = dbContext;
        DbSet = DbContext.Set<T>();
    }

    protected DbContext DbContext { get; set; }

    protected DbSet<T> DbSet { get; set; }     }

my service layer function looks like this

    public void AddPatientPayerAuthInfos(IEnumerable<PatientPayerAuthInfo> patientPayerAuthInfos)
{
    foreach (var patientPayerAuthInfo in patientPayerAuthInfos)
    {
        UOW.PatientPayerAuthInfos.Add(patientPayerAuthInfo);
    }
    UOW.SaveChanges();
}

i am writing the unit test for AddPatientPayerAuthInfos . when i try to do

var mockedUnitOfWork = new Mock<IUOW<MyDBContext>>();
    mockedUnitOfWork.SetupGet(p => p.PatientPayerAuthInfos).Returns(what should i do here ?);

PatientPayerAuthInfos is of type IRepository

i tried to do

     private object GetMockPPAIRepository()
    {
        var value = new EFRepository<PatientPayerAuthInfo>(what should i pass here);
        value.Add(new PatientPayerAuthInfo { PatientPayerAuthInfoId = 1 });
        value.Add(new PatientPayerAuthInfo { PatientPayerAuthInfoId = 2 });
        value.Add(new PatientPayerAuthInfo { PatientPayerAuthInfoId = 3 });
        return value;

    }

where EFRepository implements IRepository.

any idea ?
