<p>I know that there has been a couple questions about tutorials on rhino-mocks. But I am wondering if there are any sample apps out there that use rhino-mocks in the context of an n-tier business application using ado.net. </p>

<p>I find the tutes good, but they don't seem to bring everything all together into the big picture. Thus, I am looking for a sample app that brings the full picture together.</p>

<p>Also, I think there is a little bit of a lack of examples which specifically deal with mocking and testing the logic in the data access layer.</p>

<p>Cheers
