Flaky tests? React in real time

Identify, categorize, and take action on flaky tests with workflows to save time and resources throughout your testing process and keep the critical path clear.

Detect with precision

Configure workflows with multiple detection heuristics that identify intermittent failures and flaky test patterns to eliminate wasteful retries, and keep merge queues moving by automatically categorizing and quarantining problematic tests.

Assign team ownership

Take control of test management by mapping tests to teams and automatically assigning ownership when troublesome test cases are detected.

Customize your flaky test response

Configure workflows for different test types or teams, with fine-grained control. Create separate monitoring strategies for feature tests, unit tests, or specific environments. Generate custom notifications that range from webhooks to Slack notifications and creating Linear tickets.

Find your slowest tests, fast

See which tests are slowing your builds sooner, so you can solve your biggest problems faster.

Understand test performance

Identify and optimize slow or poor performing tests using timing data analysis from all test runs.

Use timing data to split work

Group tests into parallel jobs based on timing data—using the built-in intelligent sorting or your own rules for distributing tests.

Optimize tests on any platform

Get test insights from any CI/CD tool: Buildkite Pipelines, GitHub Actions, Jenkins, CircleCI, and more.

Get a comprehensive view of all tests

Understand what’s running and what needs attention across your test suites, all from one place. Unit tests, integration tests, end-to-end tests—see analysis of your regression testing health in a single view.

Report on progress

Automate reports on the status of unreliable or troublesome tests across teams on a configurable cadence.
