c# – 用犀牛嘲讽两次摧毁一个属性

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,我可以以某种方式覆盖已经存根的值吗？

//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

解决方法

使用Expect而不是Stub和GenerateMock而不是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);
