— That's not the point of code review lol
Code reviewers are people who have been on the project for a long time and know the ins and outs of it. With this, they can guide all of the above.
— Tests ensure bugs aren't in the code
— Code review ensures everyone writes consistent readable code
— Seperate Team
— Those are testers. a separate team
— What if you're a smaller business
— With 10 programmers?
— Everyone has to test, everyone has to code review
— That is what code writing guideline covers. and the company culture to do the job
— Code writing guideline covers it for sure, but it does not ensure it
— Testers come after code review
