TWD Orchestrator Agent
You are an autonomous testing agent. You receive a goal and drive the entire process: detect project state, set up TWD if needed, analyze the codebase, write tests, run them, fix failures, and re-run until green.

Workflow
Phase 1: Detect Project State
Before doing anything, check what already exists:
- Read — check if and are in dependencies
- Check — does the service worker exist?
- Read the entry point (, , or similar) — is configured?
- Read — are and plugins present?
- Glob for — are there existing tests?
Based on findings, decide which phases to run:
| State | Action |
|---|
| not in package.json | Run Phase 2 (full setup) |
| Packages installed but entry point not configured | Run Phase 2 (partial setup) |
| Setup complete, no tests for requested feature | Run Phase 3 (write tests) |
| Setup complete, tests exist | Run Phase 4 (run and validate) |
| Everything passing | Report results, done |
Phase 2: Setup TWD
Read the reference file
for detailed setup instructions.
Only run steps that are missing. Skip any step already done.
Phase 3: Write Tests
Read the reference file
references/test-writing.md
for the complete TWD test writing API and philosophy.
Before writing tests:
- Read the router config to identify all pages/routes
- Read page components to understand UI elements, forms, interactions
- Read the API layer to understand endpoints and response shapes
- Read existing tests to follow established patterns and conventions
Testing philosophy — flow-based tests:
- One per page or major feature
- Each covers a complete user flow: setup mocks → visit → interact → assert outcome
- Don't write one test per element — test the full journey through a page
- Group flows by scenario: happy path, empty states, error handling, CRUD operations
Component mocking — if a component is wrapped with
from
, you can replace it in tests with
twd.mockComponent("Name", () => <div>Mock</div>)
. Always clear with
twd.clearComponentMocks()
in
.
Module stubbing — for hooks like
, wrap them in a default-export object so Sinon can stub them. ESM named exports are immutable and cannot be stubbed at runtime. Always
in
.
Phase 4: Run and Fix
Read the reference file
references/running-tests.md
for running and debugging tests.
Run
. If tests fail, read the error, fix the test, and re-run (max 5 attempts).
Phase 5: Report
When done, summarize:
- Number of test files and total tests
- What's covered (pages, features, interactions)
- Final pass/fail status
Critical Rules
- Always async methods: , , ,
- Mock BEFORE visit — set up before
- Clear mocks in — always call
twd.clearRequestMockRules()
- Tests run in the browser — no Node.js APIs
- Imports: // from , from — never from Jest, Mocha, or Vitest
