使用Rhino模拟对属性进行两次存根 [英] Stubbing a property twice with rhino mocks

问题描述

对于某些对象，我想创建默认存根，以便公共属性包含值.但是在某些情况下，我想覆盖默认行为.我的问题是，我可以以某种方式覆盖已经存根的值吗?

For some objects I want to create default stubs so that common properties contains values. But in some cases I want to override my default behaviour. My question is, can I somehow overwrite an already stubbed value?

//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

推荐答案

使用Expect代替Stub，使用GenerateMock代替GenerateStub将解决此问题:

Using Expect instead of Stub and GenerateMock instead of GenerateStub will solve this:

//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);
