CI

You might say

For every PR or merge, automatically run lint, build, and key tests, with results shown on the pull request.

CI is the practice of automatically building and testing changes as they enter shared code, so integration problems appear early.A PR can automatically run lint, unit tests, and build, then write pass or fail back to the PR. This exposes issues before or just after merging. Manually testing once before release is not continuous integration.

Checks before merge

○Lint —○Unit tests —○Production build —

CI sits immediately before merge: checks report back before the merge action can open.

What CI does before shared code

Find combination problems with each change: A change that seems fine alone can fail with mainline code, dependencies, or configuration. CI repeats build and tests on a push or PR, keeping failures close to their originating commit.

Make results actionable: Checks should attach to a commit or PR and clearly show success, failure, and logs. The team can then block an unpassed merge or continue a passing version to testing.

Quick checkChoose the best answer

A team says it has CI, but only manually combines all branches and tests on Fridays. Is that right?

Not fully; checks do not run continuously with changes, so problems accumulate until merge timeYes; any final test run is CINo, because CI must automatically deploy to production

You can say this to an AI Agent

Make every PR automatically run lint, build, and critical tests, with results attached to that PR. Do not allow merge when any check fails; after passing, provide the commit, check names, and results.
