  title: Generate Deterministic Test Fixtures
  description: |
    Workflow capability that uses RandomUser to produce a reproducible batch of
    synthetic users for application test suites. Locks `seed`, `page`, `results`,
    and pinned version so the same fixture set comes back every run.
  provider: randomuser
spec:
  steps:
    - name: request-fixture-batch
      capability: randomuser-users
      operation: generateUsersVersioned
      params:
        version: "1.4"
        seed: "{{ workflow.seed }}"
        results: "{{ workflow.batchSize | default: 50 }}"
        page: "{{ workflow.page | default: 1 }}"
        nat: "{{ workflow.nationalities | default: 'us,gb,fr,de' }}"
        exc: login
      capture:
        users: $.results
        info: $.info
    - name: emit-fixture
      kind: output
      payload:
        seed: "{{ steps.request-fixture-batch.info.seed }}"
        count: "{{ steps.request-fixture-batch.info.results }}"
        users: "{{ steps.request-fixture-batch.users }}"
  guarantees:
    - Same (seed, page, results, version) returns identical users across runs.
    - No credentials required; safe for ephemeral CI runners.
