Question

我是Autofac的初学者。我最初创建了一个示例项目，然后用构造函数注入替换了所有new（）关键字。然后用Autofac替换构造函数注入，项目工作正常。

我的问题：我有我的单元测试用例，我将参数传递给构造函数，因为我用Autofac替换了我的项目。我不确定如何更换单元测试用例构造函数注入以使用Autofac。

    public class GenericHelper : IGenericHelper
    {
        private IDAL _DAL;
        private IDate _Date;

        //public GenericHelper(IDAL DAL,IDate Date)   /* Constructor injection */
        //{   _DAL = DAL;
        //    _Date = Date;
        //}

        public String CalculateMatruity(IAge AgeObj)
        {

           String Maturity = "", AgeConfiguration;

            //IDAL dalObj = _DAL;
            //IDate dateObj = _Date; 

                var builder = new ContainerBuilder();
                builder.RegisterType<AgeDAL>().As<IDAL>();
                builder.RegisterType<CurrentDate>().As<IDate>();

                using (var container = builder.Build())
                {
// AgeConfiguration = dalObj.GetMaturityConfiguration();  /* initial approach */

 AgeConfiguration = container.Resolve<IDAL>().GetMaturityConfiguration();

//Int64 Age = dateObj.Date.Year - AgeObj.Birthdate.Year;  /* initial approach */

var _d = container.Resolve<IDate>().Date.Year;

 Int64 Age = _d - AgeObj.Birthdate.Year;      /* Using autofac approach */    

 var config = AgeConfiguration.Split('|').Select(s => s.Split('=')).ToDictionary(c => c[1], c => int.Parse(c[0]));

我的错误单元测试：

[TestMethod]
        public void TestGenericHelper()
        {
            Person age = new Person();
            age.Birthdate = DateTime.Parse("1987-06-16"); 

            String expected = "Teen"; 

            DateTime FakeDate = Convert.ToDateTime("2000-01-01");
            String fake = "0=Child|13=Teen|18=Adult";

            FakeDate DateHelperObj = new FakeDate(FakeDate);
            FakeAgeDAL fakeObj = new FakeAgeDAL(fake);

            GenericHelper GenericHelperObj = new GenericHelper(fakeObj, DateHelperObj);    /* I Need to replace it use Autofac */ 

            String actual = GenericHelperObj.CalculateMatruity(age);

            Assert.AreEqual(expected, actual);
        }

我需要替换GenericHelper类实例以使用autofac但是调用虚拟对象。任何人都可以请教。
