Why We Do Code Review

> The reviewer should download the branch to their local environment, follow the deploy instructions (if present) and make sure the code “does what it says on the tin”

This looks like a very onerous requirement for reviewers (although tools like gitlab or getdockup.com automate it), I wonder if a) is really useful in catching issues, b) the process they used to convince the team to spend this extra time when reviewing. In my experience is that devs don't really want to spend more than a few minutes skimming through a PR.
