犀牛嘲讽属性两次

Question

对于某些对象，我想创建默认存根，以便公共属性包含值。但在某些情况下，我想覆盖我的默认行为。我的问题是，我能否以某种方式覆盖已经存在的值？

//First I create the default stub with a default value 
var foo = MockRepository.GenerateStub<IFoo>(); 
foo.Stub(x => x.TheValue).Return(1); 

//Somewhere else in the code I override the stubbed value 
foo.Stub(x => x.TheValue).Return(2); 

Assert.AreEqual(2, foo.TheValue); //Fails, since TheValue is 1 

Answer 1

使用Expect代替Stub和GenerateMock代替GenerateStub将解决这个问题：

//First I create the default stub with a default value 
var foo = MockRepository.GenerateMock<IFoo>(); 
foo.Expect(x => x.TheValue).Return(1); 

//Somewhere else in the code I override the stubbed value 
foo.Expect(x => x.TheValue).Return(2); 

Assert.AreEqual(1, foo.TheValue); 
Assert.AreEqual(2, foo.TheValue);
