Following up on my question yesterday about custom fields.
A couple of people pointed me at tools that analyse config before you deploy or delete something. Before I go and buy one I'd like to know how much to trust the green light.
Has anyone had one come back clean and then had something break anyway? And did you ever work out whether it hadn't checked that thing at all, or had checked it and got it wrong?
Mostly trying to work out how much of the checking I'd still need to do myself.
