这里介绍RhinoMock中的常用的类。
（一）MockRepository
RhinoMock的主要的类，是Mock仓库，用于创建mock对象，录制，重放，验证等。
（1）创建Mock
MockRepository mock
=
new
MockRepository();
（2）创建mock对象
Mock的目的就是创建mock对象，然后期望，录制重放等。创建mock对象有很多方法，以前的版本中通过：
MockRepository fac
=
new
MockRepository();
var customer = fac.CreateMock < ICustomer > ();
var customer = fac.CreateMock < ICustomer > ();
来进行，CreateMock方法已经过时，工厂方法来进行：
MockRepository fac
=
new
MockRepository();
var customer = fac.StrictMock < ICustomer > ();
var customer = fac.StrictMock < ICustomer > ();
也可以通过静态工厂方法来创建：
var customer
=
MockRepository.GenerateMock
<
ICustomer
>
();
（3）录制
所有的mock框架都使用Record/Replay模式，但有些是显示的，有些是隐式的，而RhinoMock就是显示的。
·Record/Replay传统的录制与重放：
[Test]
public void TestRR()
{
MockRepository fac = new MockRepository();
var customer = fac.StrictMock < ICustomer > ();
customer.Expect(p => p.ShowTitle( "" )).Return( "" );
customer.Replay();
Assert.AreEqual( "" , customer.ShowTitle( "" ));
}
public void TestRR()
{
MockRepository fac = new MockRepository();
var customer = fac.StrictMock < ICustomer > ();
customer.Expect(p => p.ShowTitle( "" )).Return( "" );
customer.Replay();
Assert.AreEqual( "" , customer.ShowTitle( "" ));
}
·Record，Using方式
public
void
TestRR()
{
MockRepository fac = new MockRepository();
var customer = fac.StrictMock < ICustomer > ();
using (fac.Record())
{
customer.Expect(p => p.ShowTitle( "" )).Return( "" );
}
Assert.AreEqual( "" , customer.ShowTitle( "" ));
}
{
MockRepository fac = new MockRepository();
var customer = fac.StrictMock < ICustomer > ();
using (fac.Record())
{
customer.Expect(p => p.ShowTitle( "" )).Return( "" );
}
Assert.AreEqual( "" , customer.ShowTitle( "" ));
}
·通过静态工厂方法创建mock对象：
public
void
TestRR()
{
var customer = MockRepository.GenerateMock < ICustomer > ();
customer.Expect(p => p.ShowTitle( "" )).Return( "" );
Assert.AreEqual( "" , customer.ShowTitle( "" ));
}
{
var customer = MockRepository.GenerateMock < ICustomer > ();
customer.Expect(p => p.ShowTitle( "" )).Return( "" );
Assert.AreEqual( "" , customer.ShowTitle( "" ));
}
（4）验证
用于验证mock对象的期望是否成立。
·Verify，用于验证mock对象的所有期望是否满足
·VerifyAll，用于验证所有mock对象的所有期望是否满足
（二）Expect类
为有返回值的类的方法设置期望
Call：为方法或属性提供期望
·Call<T>(T ignored)
·Call(Action actionToExecute)
例：
[Test]
public void TestCall()
{
MockRepository mock = new MockRepository();
var mockObject = mock.StrictMock < ICustomer > ();
Expect.Call(mockObject.ShowTitle( string .Empty)).Return( " 不能为空 " );
Expect.Call(mockObject.Unid).Return( 30 );
mock.ReplayAll();
Assert.AreEqual( " 不能为空 " , mockObject.ShowTitle( "" ));
Assert.AreEqual( 30 , mockObject.Unid);
}
public void TestCall()
{
MockRepository mock = new MockRepository();
var mockObject = mock.StrictMock < ICustomer > ();
Expect.Call(mockObject.ShowTitle( string .Empty)).Return( " 不能为空 " );
Expect.Call(mockObject.Unid).Return( 30 );
mock.ReplayAll();
Assert.AreEqual( " 不能为空 " , mockObject.ShowTitle( "" ));
Assert.AreEqual( 30 , mockObject.Unid);
}
看lambda表达式方式
[Test]
public void TestCall()
{
MockRepository mock = new MockRepository();
var mockObject = mock.StrictMock < ICustomer > ();
mockObject.Expect(p => p.ShowTitle( "" )).Return( " 不能为空 " );
mockObject.Expect(p => p.Unid).Return( 30 );
mock.ReplayAll();
Assert.AreEqual( " 不能为空 " , mockObject.ShowTitle( "" ));
Assert.AreEqual( 30 , mockObject.Unid);
}
public void TestCall()
{
MockRepository mock = new MockRepository();
var mockObject = mock.StrictMock < ICustomer > ();
mockObject.Expect(p => p.ShowTitle( "" )).Return( " 不能为空 " );
mockObject.Expect(p => p.Unid).Return( 30 );
mock.ReplayAll();
Assert.AreEqual( " 不能为空 " , mockObject.ShowTitle( "" ));
Assert.AreEqual( 30 , mockObject.Unid);
}
再来看Using方式
[Test]
public void TestCallUsing()
{
MockRepository mock = new MockRepository();
var mockObject = mock.StrictMock < ICustomer > ();
using (mock.Record())
{
mockObject.Expect(p => p.ShowTitle( "" )).Return( " 不能为空 " );
mockObject.Expect(p => p.Unid).Return( 30 );
}
Assert.AreEqual( " 不能为空 " , mockObject.ShowTitle( "" ));
Assert.AreEqual( 30 , mockObject.Unid);
}
public void TestCallUsing()
{
MockRepository mock = new MockRepository();
var mockObject = mock.StrictMock < ICustomer > ();
using (mock.Record())
{
mockObject.Expect(p => p.ShowTitle( "" )).Return( " 不能为空 " );
mockObject.Expect(p => p.Unid).Return( 30 );
}
Assert.AreEqual( " 不能为空 " , mockObject.ShowTitle( "" ));
Assert.AreEqual( 30 , mockObject.Unid);
}
