L'exécution pas à pas et le débogage de code pour les tests Unitaires

Je n'ai pas été en mesure de débogage ou de l'étape par le biais de test de l'unité.

Voici mon test de l'échantillon de code...

using System;
using System.Text;
using System.Collections.Generic;
using System.Linq;
using Microsoft.VisualStudio.TestTools.UnitTesting;
using DomainModel.Entities;
using DomainModel.Abstract;
using WebUI.Controllers;

namespace Tests
{
    [TestClass]
    public class PeopleControllerTests
    {

        static IPeopleRepository MockPeopleRepository(params Person[] people)
        {
            var mockPeopleRepos = new Moq.Mock<IPeopleRepository>();
            mockPeopleRepos.Setup(x => x.People).Returns(people.AsQueryable());
            return mockPeopleRepos.Object;
        }

        [TestMethod]

        public void Count_Of_People()
        {
            IPeopleRepository repository = MockPeopleRepository(
                new Person { Age = 31, Gender = "Male", Name = "Tom" },
                new Person { Age = 25, Gender = "Female", Name = "Sally" },
                new Person { Age = 18, Gender = "Female", Name = "John" }
                );

            PeopleController controller = new PeopleController(repository);
            var people = controller.List().ViewData.Model;
            var peoplelist = people as IList<Person>;
            Assert.AreEqual(3, peoplelist.Count);
        }

    }
}
