That's called functional testing and that's actually testing. You are one step removed from actually formalising what you do and getting non regression testing for free. At that point, I think you are either arguing fot the sake of it and do actually realise that testing is important or somehow confuse testing with unit testing which is only a narrow subset of it.
Users are not guinea pigs. They deserve better.
