What is a quality gate in a CI/CD pipeline?

An automated check that blocks a build or a merge from progressing until it passes, a test suite, a security scan, a coverage threshold, or a lint rule.

How do quality gates work in GitHub Actions specifically?

Through branch protection rules that require specific status checks to pass before a pull request can merge, wired to whatever your CI job reports back.

What tests should actually run before a merge?

Fast, focused checks: unit tests, linting, and API tests scoped to under ten minutes. Full regression and end-to-end suites run post-merge so they do not block a developer's flow. If your suite is Playwright, Playwright CI/CD integration shows how to wire it into the pipeline.

How do you stop flaky tests from blocking every merge?

Fix the root cause where possible, otherwise a limited retry with alerting, or quarantine the test until it is fixed, rather than letting it erode trust in the whole gate.

What is the difference between a quality gate and a deployment gate?

A quality gate runs before code merges. A deployment gate runs before that code reaches an environment, staging or production. Most pipelines need both.

Can you wire gates into a pipeline we already have, or does it need to be rebuilt?

Wired into what you already have. Most engagements add gates to an existing GitHub Actions, Jenkins, or GitLab CI pipeline rather than replacing it.

Checks that actually block a bad merge

CI/CD quality gates that stop bugs before they ship

Most pipelines run tests. Fewer of them actually stop a bad build from shipping. GoGreenlit designs and wires up quality gates covering test results, security scans, coverage thresholds, and code standards, directly into the CI/CD platform you already run.

API testsPassed

A required check failed, so the merge button stays locked. The bug never reaches the main branch.

Gate types

Gate types and where they belong in the pipeline

Not every check belongs at the same stage. Fast checks block a merge, slower ones block a deploy.

Pre-merge gates

Unit tests, linting, and focused API tests, fast enough to run in under ten minutes so they do not block a developer's flow.

Post-merge gates

Integration tests, end-to-end smoke tests, and performance checks, once code is in the main branch.

Pre-deploy gates

A fuller regression run, security scans, and a smoke test pass against staging, before anything reaches production.

Pre-release gates

Versioned build validation for products that ship discrete releases rather than continuous deployment.

Your platform

Implementing gates on the platform you already run

No pipeline migration required, gates get wired into what your team already uses.

GitHub Actions: Branch protection rules tied to required status checks, so a pull request cannot merge until every gate passes.
Jenkins: Shared pipeline libraries with gate logic defined once in a Jenkinsfile and reused across every job.
GitLab CI: Protected branches paired with merge request approval rules enforcing the same gates before a merge is allowed.

Policy

Defining go or no-go policies the whole team agrees with

1
Define pass criteria
What a gate actually checks, and what counts as a pass, agreed on before it is wired into the pipeline.
2
Set thresholds and override authority
Coverage percentages, severity thresholds, and exactly who can override a failed gate, and when.
3
Wire in and monitor
Gates go live in the pipeline, with a review point to tune thresholds once real data comes in.

Deliverables

What you actually get

Gate definitions in your repo

Configuration lives in your actual CI config, GitHub Actions YAML, a Jenkinsfile, or GitLab CI rules, version-controlled and reviewable like any other code change, not a slide deck nobody opens again.

A documented override policy

A written escalation path for the rare release that needs a gate bypassed: who can authorize it, and what has to happen before the next one ships.

Pass and fail trend visibility

A dashboard showing which gates fail most often and why, so a chronically flaky check gets fixed instead of quietly muted.

A runbook for a blocked release

A written procedure for what happens when a gate actually blocks a merge or a deploy: who gets paged, what gets checked first, how a false positive gets cleared.
