MockingContainer

測試類準備：一般來說也是業務類

    public class ClassUnderTest    {        PRivate IFirstDependency firstDep;        private ISecondDependency secondDep;        public ClassUnderTest(IFirstDependency first, ISecondDependency second)        {            this.firstDep = first;            this.secondDep = second;        }        public IList<object> CollectionMethod()        {            var firstCollection = firstDep.GetList();            return firstCollection;        }        public string StringMethod()        {            var secondString = secondDep.GetString();            return secondString;        }    }    public interface IFirstDependency    {        IList<object> GetList();    }    public interface ISecondDependency    {        string GetString();    }

　　單元測試

        [TestMethod]        public void ShouldMockDependenciesWithContainer()        {            // ARRANGE            // Creating a MockingContainer of ClassUnderTest.             // To instantiate the system uder test (the container) you should use the Instance property             // For example: container.Instance.             var container = new MockingContainer<ClassUnderTest>();            string expectedString = "Test";            // Arranging: When the GetString() method from the ISecondDependecy interface             //              is called from the container, it should return expectedString.             container.Arrange<ISecondDependency>(               secondDep => secondDep.GetString()).Returns(expectedString);            // ACT - Calling SringMethod() from the mocked instance of ClassUnderTest            var actualString = container.Instance.StringMethod();            // ASSERT            Assert.AreEqual(expectedString, actualString);        }

　　需要說明的是MockingContainer構造函數有一個可選參數AutoMockSettings，其中AutoMockSettings最主要的一個作用的是當ClassUnderTest有多個構造函數時，指定合適的構造函數來實例化對象

當業務類中有一個無參構造函數，一個有參構造函數，在沒有設置AutoMockSettings的情況下會默認執行無參構造函數，

可以像下面這樣來指定需要的構造函數

        AutoMockSettings settings = new AutoMockSettings            {                ConstructorArgTypes = new Type[]{                  typeof(IFirstDependency),typeof(ISecondDependency)                }            };            // ARRANGE            // Creating a MockingContainer of ClassUnderTest.             // To instantiate the system uder test (the container) you should use the Instance property             // For example: container.Instance.             var container = new MockingContainer<ClassUnderTest>(settings);
