## Summary Introduces `@kbn/test-es-server` as a focused package for starting/managing Elasticsearch in tests (cluster helpers, ES test config, createEsClientForTesting, cleanup, CI parallel prefix). `@kbn/test` and `@kbn/scout` depend on it and keep re-exporting the same public surface where needed so existing imports keep working. FTR-specific wiring that needs the FTR Config type stays in `@kbn/test` (e.g. `createEsClientForFtrConfig` in `ftr_es_client.ts`). `@kbn/evals` now imports `createEsClientForTesting` from `@kbn/test-es-server` instead of `@kbn/test`, aligning it with the Scout-side ES client path and trimming the implied dependency on the full test harness for that call. ### Why - Clearer boundaries: ES test-server concerns live in one place; @kbn/test stays the broader FTR/harness package. - Easier evolution: Scout and other tooling can depend on ES test infrastructure without pulling all of @kbn/test when they only need ES helpers. ### Scope - New `@kbn/test-es-server` package and repo wiring (paths, links, moon/tsconfig as required). - `@kbn/test` / `@kbn/scout`: delegate ES cluster/client/config/cleanup (and related imports) to the new package; FTR helpers remain in `@kbn/test.` - `@kbn/evals`: switch `createEsClientForTesting` to `@kbn/test-es-server` and update package references. --------- Co-authored-by: kibanamachine <42973632+kibanamachine@users.noreply.github.com> (cherry picked from commit 592399b) # Conflicts: # x-pack/platform/packages/shared/kbn-evals/moon.yml # x-pack/platform/packages/shared/kbn-evals/src/cli/commands/compare.ts # x-pack/platform/packages/shared/kbn-evals/src/evaluate.ts # x-pack/platform/packages/shared/kbn-evals/tsconfig.json
