如何使用Moq返回數據或值列表？

Question

任何人都可以告訴我如何使用模擬對象使用Moq框架返回數據列表，並將如此返回的數據列表分配給另一個列表<>變量。

Answer 1

public class SomeClass 
{ 
    public virtual List<int> GimmeSomeData() 
    { 
     throw new NotImplementedException(); 
    } 
} 

[TestClass] 
public class TestSomeClass 
{ 
    [TestMethod] 
    public void HowToMockAList() 
    { 
     var mock = new Mock<SomeClass>(); 
     mock.Setup(m => m.GimmeSomeData()).Returns(() => new List<int> {1, 2, 3}); 
     var resultList = mock.Object.GimmeSomeData(); 
     CollectionAssert.AreEquivalent(new List<int>{1,2,3},resultList); 
    } 
} 

Answer 2

@Richard Banks給出了正確的答案。爲了完整起見，如果你想使用Moq v4 functional specifications和擺脫.Object的：

void Main() 
{ 
    var list = new List<int> { 1, 2, 3 }; 

    ISomeInterface implementation = 
     Mock.Of<ISomeInterface>(si => si.GimmeSomeData() == list); 

    List<int> resultList = implementation.GimmeSomeData(); 

    foreach (int i in resultList) 
    { 
     Console.WriteLine(i); 
    } 
} 

public interface ISomeInterface 
{ 
    List<int> GimmeSomeData(); 
}
