In a branching strategy, what are CI gates typically used for?

• A. To randomize builds
• B. To automatically enforce quality checks before merging
• C. To slow down
• D. To replace tests

Answer: (B)

CI gates are used to automatically enforce quality checks before merging. In a branching workflow, when a developer opens a pull/merge request, the CI system runs a defined suite of checks on the changes—building the code, executing unit and integration tests, running linters or style checks, and possibly security or dependency scans. The merge is allowed only if these checks pass, ensuring that the main branch stays stable and that any new changes meet the project’s standards. This automatic gate provides fast feedback to developers, standardizes quality across teams, and catches issues early before they’re merged. It isn’t about randomizing builds or simply slowing things down, and it doesn’t replace tests—the tests and checks are what the gate enforces before integration.
