c# - 如何使用 Moq.MockRepository.Of() 方法

Question

Moq.MockRepository.Of() 和 Moq.MockRepository.OneOf() 的正确用法是什么？我试过类似的方法来弄清楚。

var mr = new MockRepository(MockBehavior.Strict);
var m = mr.Of<ISomeInterface>();
foreach (var obj in m)
    cnt++;

我发现 cnt 一直递增到没有尽头。是什么赋予了？与此相关的文档尚未发布。

您可以使用 Moq.MockRepository.Of() 通过表达式创建模拟。这最好用一个例子来解释:

public interface ITest
{
    String Say();
    Int32 DoSomething(Int32 a, Int32 b);
}

class Program
{
    public static void Main()
    {
        var repo = new MockRepository(MockBehavior.Strict);
        var mock = repo.Of<ITest>()
                       .Where(s => s.Say() == "Hi!")
                       .Where(s => s.DoSomething(5, 4) == 20)
                       .Where(s => s.DoSomething(4, 5) == 9)
                       .Where(s => s.DoSomething(It.IsAny<Int32>(), 7) == 99)
                       .First();

        Console.WriteLine(mock.Say());                 // prints Hi!
        Console.WriteLine(mock.DoSomething(5, 4));     // prints 20
        Console.WriteLine(mock.DoSomething(4, 5));     // prints 9
        Console.WriteLine(mock.DoSomething(23423, 7)); // prints 99
        Console.WriteLine(mock.DoSomething(0, 0));     // Fail due to MockBehavior.Strict

        Console.ReadKey();
    }
}
