Scout Create Scaffold

Generate (Preferred)

Run from the Kibana repo root:

node scripts/scout.js generate --path <moduleRoot> --type <api|ui|both>

Common variants:

# UI scaffold, sequential (non-parallel)
node scripts/scout.js generate --path <moduleRoot> --type ui --no-ui-parallel

# Generate into a custom Scout root (test/scout_<configSet>/...)
node scripts/scout.js generate --path <moduleRoot> --type both --scout-root scout_<configSet>

# If some Scout directories already exist, generate only missing sections without prompting
node scripts/scout.js generate --path <moduleRoot> --type both --force

Notes:

• The generator will not modify existing test/<scout-root>/{api,ui} sub-directories.
• If any Scout directories already exist and you pass --path, you must also pass --force (otherwise the command fails rather than prompting).

What It Creates

• API scaffold:
  • test/<scout-root>/api/playwright.config.ts
  • test/<scout-root>/api/fixtures/constants.ts
  • test/<scout-root>/api/fixtures/index.ts
  • test/<scout-root>/api/tests/example.spec.ts
• UI scaffold (sequential):
  • test/<scout-root>/ui/playwright.config.ts
  • test/<scout-root>/ui/fixtures/constants.ts
  • test/<scout-root>/ui/fixtures/index.ts
  • test/<scout-root>/ui/fixtures/page_objects/*
  • test/<scout-root>/ui/tests/example.spec.ts
• UI scaffold (parallel):
  • test/<scout-root>/ui/parallel.playwright.config.ts
  • test/<scout-root>/ui/parallel_tests/example_one.spec.ts
  • test/<scout-root>/ui/parallel_tests/example_two.spec.ts
  • test/<scout-root>/ui/parallel_tests/global.setup.ts

The generator does not create tsconfig.json files. Playwright runs without them, but node scripts/type_check (CI) must still include Scout specs in a TS project—see TypeScript layout below.

TypeScript layout (check_types)

Pick one pattern and wire it after scout.js generate completes:

Pattern A — plugin root includes Scout (e.g. discover_enhanced)

• In the plugin or package root tsconfig.json, add test/<scout-root>/**/* (or broader test/**/*) to include.
• Add kbn_references for the Scout stack you use:
  • Platform / generic: @kbn/scout.
  • Observability: @kbn/scout-oblt; for API tests using synthtrace workers, also @kbn/scout-synthtrace, @kbn/synthtrace-client (and @kbn/rison for UI if needed).
  • Match sibling plugins in the same solution for consistency.
• Do not add nested test/<scout-root>/{ui,api}/tsconfig.json when using this pattern (one program for plugin + Scout).
• Allows relative imports from specs/fixtures into server/ or common/ when the test needs shared registration constants or light server utilities.

Pattern B — dedicated tsconfig.json under test/<scout-root>/{ui,api}/

• Add test/<scout-root>/api/tsconfig.json and/or test/<scout-root>/ui/tsconfig.json with extends, include: ["**/*"], and scoped kbn_references (see SLO, data_views, infra Scout modules for examples).
• Keeps the main plugin typecheck smaller.
• Does not allow relative imports that climb into ../../../../server/... or public/... from those folders—TypeScript will treat server/** as part of the wrong composite project (TS6059 / TS6307). Use fixtures/constants.ts, common/, or switch to Pattern A.

After wiring either pattern

1. Run yarn kbn bootstrap so packages/kbn-ts-projects/config-paths.json picks up added or removed tsconfig.json paths.
2. Validate with node scripts/type_check --project <path-to-tsconfig.json> (plugin root tsconfig.json for A, or test/<scout-root>/api/tsconfig.json / UI sibling for B).

After Generating

• Custom server config sets:
  • If you create/use test/scout_<configSet>, you typically also need a matching server config under src/platform/packages/shared/kbn-scout/src/servers/configs/config_sets/<configSet>.
  • start-server requires --serverConfigSet <configSet> when using a custom server config set.

Path Conventions (Specs)

• UI sequential specs: test/scout*/ui/tests/**/*.spec.ts
• UI parallel specs: test/scout*/ui/parallel_tests/**/*.spec.ts
• API specs: test/scout*/api/tests/**/*.spec.ts
