Flaky Test Trend Alert from CI Metrics to Slack
Runs on a schedule, queries Datadog CI test metrics for tests whose flake rate crossed a threshold over the last week.
How it runs
The automated pipeline, trigger to output.
- TriggerScheduled weekday run
- ActionQuery Datadog CI flake ratesDatadog
- LogicFilter and rank tests above threshold
- ActionFormat ranked flake digest
- OutputPost digest to Slack channelSlack
What it does
This workflow surfaces the flakiest tests before they become emergencies. On a regular cadence it pulls per-test pass/fail rates from Datadog CI Visibility, ranks tests by flake rate and blast radius, and delivers a prioritized digest to Slack so the team fixes the top offenders instead of guessing.
When to use it
Use this for a weekly or daily flake review when you already ship CI test metrics to Datadog. It is the proactive complement to per-failure quarantine — it tells you what to invest in.
How it works
- 1A scheduled trigger fires (for example, every weekday morning).
- 2An action queries Datadog for test-level flake rates over the trailing window.
- 3A logic step filters to tests above the flake-rate threshold and ranks by impact.
- 4An action formats a digest with sparkline-style counts and owning teams.
- 5The output posts the ranked digest to the engineering Slack channel.
