What Trunk Flaky Tests is
Trunk Flaky Tests detects, quarantines, and helps teams address unreliable tests across languages, test runners, and CI providers. Its AI groups related failures to reveal patterns, reasons, and trends, while automatic quarantine lets flaky tests keep running without failing CI workflows or requiring code changes. Analytics track test status history, flake rates, failure reasons, and runs across environments. The service integrates with CI providers including GitHub Actions, Jenkins, CircleCI, and Bitbucket Pipelines, plus Jira; Slack alerts and webhooks can report test events. The free plan supports up to five committers and five million test spans monthly, with soft limits that trigger an upgrade banner when exceeded. Trunk says setup takes a few minutes and users can start without a credit card. The product is available on-premise in private preview, and Enterprise lists on-premise deployment. Trunk states it maintains SOC 2 Type I and Type II compliance and encrypts data at rest and in transit.
