## Summary It seems the jest unit test grouping through `ci-stats` is broken. It's probably because we no longer run and report empty test configs (after elastic#236549 we skip empty configs), thus CI stats will no longer be able to have an accurate guess as to how long they will take. Calculating with the default guessed config runtimes results in weird buckets. We went from ~23 jest unit test groups to ~53 (again, probably because the empty configs, that would run in a few seconds are counted as if they take a few minutes + overhead). This PR updates the `pick_test_group_run_order` logic, such that we no longer ask grouping for the configs that don't contain any test files to run. The result reset the jest unit parallel group count back to 23. For this, I'm using jest's internal utilities to search for test files, and had to bootstrap the step, so that the resolution doesn't break. --------- Co-authored-by: kibanamachine <42973632+kibanamachine@users.noreply.github.com> (cherry picked from commit 4889045) # Conflicts: # .buildkite/pipeline-utils/ci-stats/pick_test_group_run_order.ts # .buildkite/pipeline-utils/scout/index.ts # .buildkite/pipeline-utils/scout/pick_scout_test_group_run_order.ts # .buildkite/pipelines/fips/fips_pipeline.ts # .buildkite/scripts/steps/test/pick_test_group_run_order.sh # src/platform/packages/shared/kbn-test-saml-auth/jest.config.js
