Your thoughts on Code Reviews
(feddit.it)
Hey, I want your opinion on code reviews, what is the best way to use them in a professional environment? Pick one of the following and give me your thoughts (from the most forgiving to the most strict):
- no code reviews, they are useless
- optional code reviews
- mandatory reviews on code that is already merged, optional fixes
- mandatory reviews on code before merging (like a pull request), with a time-frame for optional fixes (i.e. whether to fix what has been pointed out is up to the author), merge will occur anyway.
- mandatory reviews on code before merging (PR) with mandatory fixes.
Of course in open source development with public contributions, you'll often see (5), but I'm not convinced it could work in professional dev.
Edit: I'm talking about a team of 5 mid to senior devs (no junior or interns) working on a 2-3 year project without many security concerns, but feel free to give me your general opinion.
5 with reasonable acceptance and use, even advocacy, for up to 1. I don't see a difference between 4 and 5, though.
Reviews should be the norm. Even for simple changes, a simple code change should be simple to review and approve, too. At the same time, some formatting changes or small or minimal changes with high confidence can be pushed to main without review - that'd be just wasted time and effort on the reviewer's side. High urgency can also warrant an immediate push to main, or live hotfixing on prod if possible, with a corresponding PR still open.
