Maybe, depends on their workflow. In my human workflow, I tend to use commits as checkpoints and then squash before pushing. I'd usually only run time-consuming tests before squash+push.

But yes, anything you want to ensure really needs to be a hook.

edit: realizing with "precommit" you probably meant a git hook not one in their harness. I'd have written the same response more or less though. :)

Oh yes - definitely the git kind of hook. Also, I always forget that there’s a pre-push hook as well. So you don’t need to do things every commit.

But then you could just be storing up a lot of problems…
