Moq适合于TDD的项目，小项目初期应该不太适合使用，有些浪费时间了！

NuGet 分别添加 NUnit 和 Moq

install-package nunit -project 测试项目名称

install-package moq -project 测试项目名称

public class Person

    {

        public string Id;

        public string FirstName;

        public string LastName;

        public Person(string newId, string fn, string ln)

        {

            Id = newId;

            FirstName = fn;

            LastName = ln;

        }

    }

    public interface IPersonRepository

    {

        List<Person> GetPeople();

        Person GetPersonById(string id);

    }

    public class PersonService

    {

        private IPersonRepository personRepos;

        public PersonService(IPersonRepository repos)

        {

            personRepos = repos;

        }

        public List<Person> GetAllPeople()

        {

            return personRepos.GetPeople();

        }

        public List<Person> GetAllPeopleSorted()

        {

            List<Person> people = personRepos.GetPeople();

            people.Sort(delegate(Person lhp, Person rhp)

            {

                return lhp.LastName.CompareTo(rhp.LastName);

            });

            return people;

        }

        public Person GetPerson(string id)

        {

            try

            {

                return personRepos.GetPersonById(id);

            }

            catch (ArgumentException)

            {

                return null; // no person with that id was found

            }

        }

    }

Moq

[TestFixture]

    public class NUnitTest

    {

        private Mock<IPersonRepository> mo = new Mock<IPersonRepository>();

        private Person onePerson = new Person("", "Wendy", "Whiner");

        private Person secondPerson = new Person("", "Aaron", "Adams");

        private List<Person> peopleList;

        /// <summary>

        ///     填充基础数据

        /// </summary>

        [SetUp]//每个测试方法被调用之前执行

        [Category("Mock")]

        public void Init()

        {

            peopleList = new List<Person>();

            peopleList.Add(onePerson);

            peopleList.Add(secondPerson);

        }

        [Test]

        [Category("Mock")]

        public void TestGetAllPeople()

        {

            //模拟使用接口方法及返还数据

            mo.Setup(m => m.GetPeople()).Returns(peopleList);

            PersonService service = new PersonService(mo.Object);

            Assert.AreEqual(, service.GetAllPeople().Count);

        }

        [Test]

        [Category("Mock")]

        public void TestGetAllPeopleSorted()

        {

            mo.Setup(m => m.GetPeople()).Returns(peopleList);

            PersonService service = new PersonService(mo.Object);

            var p  = service.GetAllPeopleSorted()[];

            Assert.AreEqual("Adams", p.LastName);

        }

        [Test]

        [Category("Mock")]

        public void TestGetSinglePersonWithValidId()

        {

            mo.Setup(m => m.GetPersonById(It.Is<string>(s => s == "")))

                .Returns(onePerson);

            PersonService service = new PersonService(mo.Object);

            var p = service.GetPerson("");

            Assert.IsNotNull(p);

            Assert.AreEqual(p.Id, "");

        }

        [Test]

        [Category("Mock")]

        public void TestGetSinglePersonWithInalidId()

        {

            mo.Setup(m => m.GetPersonById(It.IsAny<string>()));

            PersonService service = new PersonService(mo.Object);

            Assert.IsNull(service.GetPerson(null));

        }

    }
