c# - 用 rhino mocks 对一个属性进行 stub 两次

Question

对于某些对象，我想创建默认 stub ，以便公共(public)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 stub 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 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);
