About Buildkite Test Engine
Buildkite Test Engine is a set of tools for managing flaky tests and test speed in continuous integration. It is part of the Buildkite platform.
What it does
The engine detects flaky tests with several heuristics, then quarantines them so they stop blocking merge queues. Owners can be assigned to tests automatically when problems appear. Timing data shows the slowest tests, and intelligent test splitting spreads work across parallel jobs to save time. Notifications can go to webhooks, Slack or Linear.
Key features
- Flaky test detection and quarantine
- Test ownership assignment to teams
- Timing analysis for slow tests
- Notifications through webhooks, Slack or Linear
Who it's for
Engineering teams with slow or unstable test suites, especially teams with large CI pipelines and merge queues.
Pricing and good to know
Buildkite offers an all-access trial that you can start from the site. The product works with existing CI compute, so teams can get more out of the infrastructure they already run. The platform also includes pipelines and package registries alongside the test tools.
Highlights
- Detect and quarantine flaky tests
- Assign test owners to teams
- Find the slowest tests by timing data
- Send alerts to Slack, webhooks or Linear
