用犀牛嘲笑两次捣毁财产

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

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);
