(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
>
();
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
>
();
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(
""
));
}
·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(
""
));
}
·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(
""
));
}
(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);
}
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);
}
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);
}
