Trunk Flaky Tests
What Trunk Flaky Tests is
Trunk Flaky Tests helps software teams identify and manage unreliable tests across languages, test runners, and CI providers. Its AI groups related failures to show patterns, possible reasons, and trends over time. Tests can be quarantined automatically without code changes, allowing them to keep running without failing CI workflows. Analytics include test status history, flake rates, failure reasons, and test runs across environments. Supported CI providers include GitHub Actions, Jenkins, CircleCI, Bitbucket Pipelines, Azure DevOps Pipelines, Buildkite, GitLab, and others; Jira is listed as a ticketing tool. Slack alerts and webhooks can report test events. The Free plan supports up to five repo committers and five million test spans per month, with soft limits that show an upgrade banner when exceeded. Trunk says setup takes a few minutes and users can start without a credit card. Team and Enterprise trials can be requested with technical support, but no trial duration is stated. On-premise availability is described as a private preview, while Enterprise lists on-premise deployment. Trunk says it maintains SOC 2 Type I and Type II compliance and encrypts customer data at rest and in transit.
