I can’t speak for all companies but at the place I worked at, there was a monorepo. You’d create a small, self contained change off the main branch and put it up for review. All such proposed changes would have tests run on them, so the reviewer could get a sense of the quality of changes. “Looks good, please fix that test” was a comment I’ve seen more than once. After approval, it’ll land on main and be in prod within an hour or two. For larger features, these changes could be stacked in a list. After each change in the list had been approved, they’d be landed on main as an all or nothing.
