Create Scout Scaffold (Generator-First)

Related skills

• scout-migrate-from-ftr — After generating files, wire TypeScript for CI using Pattern A or Pattern B (Where Scout tests are typechecked in that skill). This skill documents layout; the migration skill has the full rules (relative imports, kbnreferences, node scripts/typecheck --project …).

Inputs to Collect

• Module root (repo-relative path to the plugin/package directory, e.g. x-pack/platform/plugins/shared/maps)
• Test type: api, ui, or both
• Scout root directory name under <moduleRoot>/test/

- Default: scout (creates <moduleRoot>/test/scout/...) - Custom config set: scout<configSet> (for example scoutuiamlocal, scoutcspm_agentless)

• Optional namespace for a functional area in a large plugin (creates test/<scout-root>/<namespace>/{ui,api})

- One level only; lowercase letters, digits, and underscores - Do not mix root-level {ui,api} directories with namespaces in the same Scout root

• For UI scaffolds: whether tests can run in parallel (space-isolated). Default is parallel; use sequential when isolation is not possible.

Generate (Preferred)

Run from the Kibana repo root:

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

Common variants:

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

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

# Generate a functional-area namespace in a large plugin
node scripts/scout generate --path <moduleRoot> --type both --namespace <namespace>

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

Notes:

• The generator will not modify existing test/<scout-root>/{api,ui} or test/<scout-root>/<namespace>/{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).
• In the paths below, <scout-content-root> means test/<scout-root> or test/<scout-root>/<namespace>.

What It Creates

• API scaffold:

- <scout-content-root>/api/playwright.config.ts - <scout-content-root>/api/fixtures/constants.ts - <scout-content-root>/api/fixtures/index.ts - <scout-content-root>/api/tests/example.spec.ts

• UI scaffold (sequential):

- <scout-content-root>/ui/playwright.config.ts - <scout-content-root>/ui/fixtures/constants.ts - <scout-content-root>/ui/fixtures/index.ts - <scout-content-root>/ui/fixtures/page_objects/* - <scout-content-root>/ui/tests/example.spec.ts

• UI scaffold (parallel):

- <scout-content-root>/ui/parallel.playwright.config.ts - <scout-content-root>/ui/paralleltests/exampleone.spec.ts - <scout-content-root>/ui/paralleltests/exampletwo.spec.ts - <scout-content-root>/ui/paralleltests/global.setup.ts - <scout-content-root>/ui/paralleltests/global.teardown.ts is not generated; opt in by adding the file with a globalTeardownHook(...) call. See scout-ui-testing/references/scout-ui-parallelism.md.

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 node scripts/scout 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 <scout-content-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 <scout-content-root>/{ui,api}/

• Add <scout-content-root>/api/tsconfig.json and/or <scout-content-root>/ui/tsconfig.json with extends, include: ["**/*"], and scoped kbnreferences (see SLO, dataviews, 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 the API/UI tsconfig.json under <scout-content-root> for B).

After Generating

There is no need to run node scripts/scout update-test-config-manifests. CI takes care of this for you.

• 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/configsets/<configSet>. - start-server requires --serverConfigSet <configSet> when using a custom server config set.

Path Conventions (Specs)

<scout-content-root> may be test/scout or test/scout/<namespace>.

• UI sequential specs: <scout-content-root>/ui/tests/**/*.spec.ts
• UI parallel specs: <scout-content-root>/ui/parallel_tests/**/*.spec.ts
• API specs: <scout-content-root>/api/tests/**/*.spec.ts
