在 Rhino Mocks 中处理参数化调用

Question

我有一个邮件程序 class，它有一个 "SendMessage" 方法，需要一个实现接口 IEMailConfiguration 的对象。我想模拟邮件程序，使其不发送邮件，而只是将给定的邮件配置对象添加到列表中。

这是我目前得到的（不是太多，我知道）：

 var mailsSent = new List<IEmailConfiguration>();
 mailerMock = MockRepository.GenerateStrictMock<Mailer>();

我已经使用 Expect() 和 Do() 调用来模拟无参数调用，这相当简单，但现在我没有看到解决方案：How do i get the argument of the Expect part to be used in做电话吗？

mailerMock.Expect( x=> x.SendMessage(**AnyConfiguration**)).Do(mailsSent.Add(**AnyConfiguration**)

可能您想使用 WhenCalled 方法：

    class Program
    {
        static void Main()
        {
        List<IEmailConfiguration> performedCalls = new List<IEmailConfiguration>();

        // preparing test instance
        var mailerMock = MockRepository.GenerateStrictMock<Mailer>();
        mailerMock.Expect(x => x.SendMessage(Arg<DummyEmailConfiguration>.Is.Anything))
                  .WhenCalled(methodInvocation => // that's what you need
                  {
                      var config = methodInvocation.Arguments.OfType<IEmailConfiguration>().Single();
                      performedCalls.Add(config);
                  });

        // testing 
        for (int i = 0; i < 10; i++)
        {
            mailerMock.SendMessage(new DummyEmailConfiguration("world" + i + "@mail.com", "hello world" + i));
        }

        // dumping info
        foreach (var call in performedCalls)
        {
            Console.WriteLine(call);
        }
    }
}

public interface IEmailConfiguration
{
    string To { get; }
    string Message { get; }
}

public interface Mailer
{
    void SendMessage(IEmailConfiguration config);
}

internal class DummyEmailConfiguration : IEmailConfiguration
{
    public DummyEmailConfiguration(string to, string message)
    {
        To = to;
        Message = message;
    }

    public string To
    {
        get;
        private set;
    }

    public string Message
    {
        get;
        private set;
    }
    public override string ToString()
    {
        return To + ": " + Message;
    }
}
