Required review

Learn the required review rule.

What Is a Required Review?

You can require a pull request to be reviewed by another team member before it is merged. On GitHub, this rule prevents changes from being merged into a protected branch until the required number of approvals is received. This allows code changes to be checked by another person.

main:
  required_approvals: 1

It helps identify mistakes early, especially in team projects.

Approval and Review Policy

You can specify how many approvals are needed in a required review rule. For example, required_approvals: 1 requires at least one approval. GitHub also does not count the pull request author's own approval as a valid team approval.

pull_request:
  required_approvals: 1
  dismiss_stale_reviews: true

The dismiss_stale_reviews option makes previous approvals invalid when new commits are pushed after the review.

Practice Require Two Approvals

Configure a pull request review policy for the main branch. Set required_approvals to 2 and set dismiss_stale_reviews to true to invalidate previous approvals when new commits arrive.

Starter code

terminal
# İnceleme politikası oluştur
# Gerekli onay sayısını belirle
# Eski onayları geçersiz kıl

Sample solution

terminal
main:
  pull_request:
    required_approvals: 2
    dismiss_stale_reviews: true

Expected output

İki onay zorunlu hale getirildi.
