I didn't realise rendering_views was that light, how did you test that?

So what I had in mind was testing all the data's rendered correctly - Release date, Display date, Type, Organisation, Topic, etc.  This way we get a sot mini-integration test covering the whole view at very little additional cost.  I know it's not so important for a simple admin view like that but given you're rendering the template anyway, why not have it?
