犀牛嘲諷屬性兩次

Question

對於某些對象，我想創建默認存根，以便公共屬性包含值。但在某些情況下，我想覆蓋我的默認行爲。我的問題是，我能否以某種方式覆蓋已經存在的值？

//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將解決這個問題：

//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);
