If a test or feature is flaky or unstable, you can quarantine it to prevent it from failing pipelines. This allows pipelines to continue running without being affected. Once a test is quarantined, it will be skipped in all environments, and across all branches, until it is unquarantined.

​
How to quarantine a test

​
CLI

You can quarantine and unquarantine tests using the quarantine command in the Momentic CLI. 
npx momentic quarantine add <test> --reason <reason>

​
Cloud

Select Quarantine on the left sidebar, and click the Quarantine test button in the top right corner.
To unquarantine a test, navigate to the same page, hover over the test to unquarantine, and select the Unquarantine option in the dropdown menu.
You can also quarantine a test directly from the run viewer, by clicking on the Quarantine test button in the top right corner of the page.

​
Quarantine rules

Quarantine rules are a way to define thresholds past which tests are automatically quarantined or unquarantined. This allows you to easily keep your test suite running smoothly without taking manual action.

​
Rule

The rule defines both the action to be taken, as well as when to take it. You can configure:
  • Whether to quarantine or unquarantine the test.
  • Which metric to use (options include pass rate, number of failures, and flake rate).
  • What threshold triggers the action.
  • What period to evaluate the metric over.

​
Filtering

In order to create more granular rules, you can configure additional filters so that the rule only applies to certain tests and runs:
  • Only apply to tests in a specific repository.
  • Only include runs on a particular branch. This is useful for quarantining tests that fail too often on main.
  • Only include tests with particular labels. This is useful if you have stricter rules for particular suites.
