Hi, If I understand right you want to test that a view component is being called in a specified way and the component is not easy to test. if this is not the case then the rest of my opst might not apply as it is not an answer about Rhino mocks but more about testing interaction with a "complicated" component :)
A way to test this interaction could be to extract an interface from your components and then test your componentController/presenter (your helper class) agaisnt those interface. in the production code you can make the component implement the interface or have a thin wrapper implementing the interface around the concrete component if you can't change it. It is now possible to send the component/wrapper using the interface to your helper class . If you need a Wrapper you can make the wrapper so dum that it is ok not to test it. collection = repository.StrictMock<IRadItemCollection>(); // note using an interface, has methods Clear and Add comboBox = repository.StrictMock<IRadComboBox>(); // has methods SuspendLayout etc btw, can't you use the AAA-syntax? It is usually easier IMHO Dom On Mar 9, 12:15 am, BaRuSa <[email protected]> wrote: > The Rad components are third party controls that I do not have control > of changing the way they work.
