Introducing Quarantine

Velocity shouldn’t stall because one test, feature, or third-party dependency got noisy. Quarantine gives your devX and infra teams a fast way to triage and isolate failing tests so engineers keep merging, deploying, and moving.

Why we built it

Flaky tests and unstable features slow merges, block deploys, and pages on-call.

Teams often build internal quarantine systems that take real time and headcount to maintain. Our customers wanted an out-of-the-box solution that removes the fire drill without losing visibility or quality.

How it works

  • One-click quarantine. Pull a failing test out of your critical path immediately while Momentic keeps tracking its health in the background.
  • Rules and automation. Set custom metrics and thresholds to automatically quarantine or unquarantine when conditions are met.
  • CI-native. Plug it into your pipelines and keep everyone in the loop with targeted notifications. Works out of the box with our CLI: momentic.

Common use cases

  1. Unblock PRs fast. Quarantine a flaky test so product velocity remains high while you investigate.
  2. Stabilize hot spots. Isolate tests around an actively changing area of the product to reduce noise.
  3. Guardrails for reliability. Auto-quarantine when failure rate or duration exceeds a threshold, then auto-return once stability recovers.
  4. Keep visibility. Even while quarantined, tests remain monitored and reported so you do not fly blind.

Building the AI-native testing platform

Quarantine serves the entire engineering org from one shared source of truth for pipeline reliability.

Engineers get unblocked from shipping instantly. devX and infra can instantly triage and isolate tests, track metrics, and set custom rules and thresholds. Everyone gets notified instantly via Slack whenever a quarantine event occurs.

Infrastructure that you can depend on as your quality gates.

What’s next

Now Quarantine bring enterprise-level infrastructure and tooling to teams of any size.

Quarantine moves us closer to our ultimate vision: transforming Momentic into the AI-native testing platform.
