The Application Development Experiences of an Enterprise Developer

Order Matters in the Rhino Mocks Fluent Interface

Posted by bsstahl on 2012-01-16 and Filed Under: development 


I noticed something interesting with Rhino Mocks today while testing some demo code: Rhino.Mocks.Expect.Call(myDependency.MyMethod(param1)).Return(result).Repeat.Times(5); behaves as I anticipated; it expects the call to MyMethod to be repeated 5 times and returns the value of result all 5 times. Meanwhile: Rhino.Mocks.Expect.Call(myDependency.MyMethod(param1)).Repeat.Times(5).Return(result); also has the expectation of 5 executions, but it returns the value of result only once. The other 4 executions return 0.

When I think about it now, it makes sense, but it wasn't the behavior I originally expected.
