Nightly Jobs

The nightly jobs are scheduled job runs that can be triggered using the Pilot framework. These jobs can be used to identify flakes by running the same test on an existing green build. Nightly jobs are also configured using the YAML config file:

scenarios:
- name: "nightly build"
  trigger:
    schedule:
      cron_utc: "0 12 * * *"  # Every day at 12pm UTC
  actions:
  - test_suite:
      rerun:
        name: "buildkite/pytest"
        count: 5
        use_latest_green_commit: true
        branch: "master"

Note that the cron_utc config ignores the minute level precision. You can run it at most at an hourly cadence.
