Code reviews do find bugs

2 days ago

Code reviews are effective in finding bugs, contrary to some research suggesting otherwise.
About 15% of code review comments indicate possible defects, but this doesn't reflect the defect detection rate.
Code review and pair programming can find an additional 60% of defects with only a 15% increase in time investment.
Reviewers find roughly one defect per ten minutes when reviewing less than 50 lines of code in the first 60 minutes of the day.
Code review is highly effective for learning the codebase, with reviewers becoming familiar after about four reviews.
Feedback on long-term code maintainability makes up 50% of code review comments, which is beneficial.
The median review turnaround time of 24 hours is too long and can hinder productivity.
Best practices for code reviews should be followed before judging their effectiveness.
