（一）次序（Ordered）

在rhinomock中，可以按次序调用方法。默认条件下，方法调用没有顺序。如果按次序录制，那么在调用方法时必须按录制时相同的次序进行。

 

请看：

public interface ICustomer
{
   string ShowTitle(string str);
   int Unid { get; set; }
   string CustomerName { get; set; }
   string Address { get; set; }
}

 

测试：

public void TestNoOrder()
{
    MockRepository mocks = new MockRepository(); 
    ICustomer customer = mocks.StrictMock<ICustomer>(); 
    //默认条件下是没顺序的
    Expect.Call(customer.Unid).Return(1);
    Expect.Call(customer.CustomerName).Return("宋江");
    Expect.Call(customer.Address).Return("山东"); 
    mocks.ReplayAll(); 
    Assert.AreEqual("宋江", customer.CustomerName);
    Assert.AreEqual(1, customer.Unid);
    Assert.AreEqual("山东", customer.Address);
}

 

 

当使用次序时：

public void TestOrder()
{
    MockRepository mocks = new MockRepository(); 
    ICustomer customer = mocks.StrictMock<ICustomer>();
    using (mocks.Ordered())
    {
        Expect.Call(customer.Unid).Return(1);
        Expect.Call(customer.CustomerName).Return("宋江");
        Expect.Call(customer.Address).Return("山东");
    } 
    mocks.ReplayAll();
    Assert.AreEqual("宋江", customer.CustomerName);
    Assert.AreEqual(1, customer.Unid);
    Assert.AreEqual("山东", customer.Address);
}

 

这时，如果调用时没有按期望时的次序进行，那就会出错，抛出异常。

这种次序可以灵活使用，例如可以次序一个mock，然后期望条件达到后，再不按次序进行。注意：在进行回播前要退出次序。

 

（二）模拟委托

先定义委托：

public delegate void DoThing(string strMsg);

  

然后模拟委托：

[Test]
public void TestDelegate1()
{
    MockRepository mocks = new MockRepository();
    var oo = mocks.DynamicMock<DoThing>();
    oo("");
    mocks.ReplayAll();
    oo("");
    mocks.VerifyAll();
}

 

有两个系统定义的委托Func<TResult>和Action<T>

前是带返回值的委托，后者不带返回值，现在通过Action<T>来实现上例

[Test]
public void TestDelegate2()
{
    MockRepository mocks = new MockRepository();
    var oo = mocks.DynamicMock<Action<string>>();
    oo("");
    mocks.ReplayAll();
    oo("");
    mocks.VerifyAll();
}

 

再来一个Func，即带返回值的委托的例子：

[Test]
public void TestDelegateFunc()
{
    MockRepository mocks = new MockRepository();
    var oo = mocks.DynamicMock<Func<string, string>>();
    Expect.Call(oo("")).Return("abc");
    mocks.ReplayAll();
    Assert.AreEqual("abc", oo(""));
}

 

 

再来一个例子：

public class Customer
{
     Func<string, string> _fun;
     public Customer(Func<string, string> fun)
     {
          _fun = fun;
     }
     public void DoSomething(string strMsg)
     {
          Console.WriteLine(_fun(strMsg));
     }
}

 

 

测试：

[Test]
public void TestDelegateFunc()
{
    MockRepository mocks = new MockRepository();
    var oo = mocks.DynamicMock<Func<string, string>>();
    Expect.Call(oo("")).Return("abc");
    mocks.ReplayAll(); 
    var customer = new Customer(oo);
    customer.DoSomething("");
}
