Smallest possible foundation for the persona-driven visual regression
suite (M5 in docs/plans/mana-mcp-and-personas.md). One flow, two
viewports, one persona — enough to prove the stack end-to-end:
seed-script → mana-auth → API login → cookie injection → web app →
screenshot → disk. Extending is copy-paste per flow.
tests/personas/
playwright.config.ts
Own config separate from the root tests/e2e/ suite. Two viewports
(1440×900 desktop Chrome + Pixel 5 mobile) — more can be added
once baselines settle without quadrupling the review load.
Diff threshold 0.2 %, animations disabled, snapshots land under
__snapshots__/{spec}/{arg}-{project}.png. No auto-webServer —
the whole point is to catch regressions against the real stack
the user runs, not a hermetic one; if the stack is down, tests
fail loud.
fixtures/persona-auth.ts
Typed Playwright `test.extend` with a `personaKey` worker option
and a `personaPage` fixture that returns a pre-logged-in Page
pointed at `/`. Login is API-side: POST /api/v1/auth/login with
the deterministic HMAC-SHA256 password, parse Set-Cookie headers,
inject into the browser context. Derivation is a bit-identical
mirror of scripts/personas/password.ts and
services/mana-persona-runner/src/password.ts — a 3-way contract.
Changing one without the others locks the suite out of every
persona. PERSONAS map exports all 10 catalog emails for typed
access.
flows/home.spec.ts
One smoke flow. Asserts the persona isn't redirected to /login,
hides any [data-testid="live-time"] so clock widgets don't
invalidate diffs, captures a full-page screenshot. When this
goes green, the whole pipeline is plumbed. Copy this file to
add per-module tours.
package.json
@mana/tests-personas workspace. Scripts: `test`, `test:update`,
`report` (HTML diff viewer).
README.md
Prerequisites (stack up + seeded + ideally persona-runner ticked
once), run recipe, env vars, architecture diagram, extension
pattern.
root package.json: `pnpm test:personas` + `:update`.
.gitignore: playwright-report-personas/ + test-results/ so generated
artefacts never get committed.
Type-check / list: `playwright test --list` succeeds, 2 tests (one
per viewport) registered for home.spec.ts.
Not attempted in this commit (user action to run the stack):
- Actual baseline capture (needs docker up + db:push + seed:personas
+ ANTHROPIC_API_KEY + diag/tick).
- Additional flows (todo, journal, notes, habits, calendar). They're
copy-paste per README. Land when the stack is smoked.
- Nightly CI job. Will land once baselines are stable.

# Persona Visual Suite
|
||
|
||
Playwright-driven visual regression tests that log in as each of the **M2 personas**, navigate through the modules the persona uses, and diff screenshots against committed baselines. Detects UI regressions before real users do.
|
||
|
||
**Plan:** [`docs/plans/mana-mcp-and-personas.md`](../../docs/plans/mana-mcp-and-personas.md) (M5)
|
||
|
||
## Prerequisites
|
||
|
||
The suite assumes the full local stack is already running and **seeded with persona data**. It does *not* auto-start anything — a silent "all green" against an empty seed would hide regressions, not find them.
|
||
|
||
```bash
|
||
# 1. Stack up + seeded
|
||
pnpm docker:up
|
||
cd services/mana-auth && bun run db:push
|
||
pnpm dev:auth # mana-auth on 3001
|
||
pnpm dev:sync # mana-sync on 3050
|
||
pnpm mana:dev # web app on 5173 — the suite hits this
|
||
|
||
# 2. Seed the 10 catalog personas
|
||
export MANA_ADMIN_JWT=…
|
||
export PERSONA_SEED_SECRET=… # same value the suite uses below
|
||
pnpm seed:personas
|
||
|
||
# 3. Optional but recommended: run the persona-runner once so each
|
||
# persona has real content. Empty accounts make empty baselines.
|
||
pnpm --filter @mana/mcp-service dev # :3069
|
||
pnpm --filter @mana/persona-runner dev # :3070
|
||
export MANA_SERVICE_KEY=…
|
||
export ANTHROPIC_API_KEY=…
|
||
curl -X POST localhost:3070/diag/tick
|
||
```
|
||
|
||
## Running
|
||
|
||
```bash
|
||
cd tests/personas
|
||
|
||
# First run — captures baselines (or diffs against existing ones):
|
||
pnpm test
|
||
|
||
# Accept current render as new baseline (after intentional UI changes):
|
||
pnpm test:update
|
||
|
||
# View the HTML report with diff visualisations:
|
||
pnpm report
|
||
```
|
||
|
||
## Environment
|
||
|
||
| Var | Default | Purpose |
|
||
|---|---|---|
|
||
| `PERSONAS_AUTH_URL` | `http://localhost:3001` | mana-auth for API login |
|
||
| `PERSONAS_BASE_URL` | `http://localhost:5173` | web app the browser loads |
|
||
| `PERSONAS_COOKIE_DOMAIN` | derived from `PERSONAS_BASE_URL` host | Where better-auth's cookie lands |
|
||
| `PERSONA_SEED_SECRET` | dev fallback | MUST match `scripts/personas/password.ts` and the runner |
|
||
|
||
## Architecture
|
||
|
||
```
|
||
┌──────────────────────────────────────────────┐
|
||
│ tests/personas/fixtures/persona-auth.ts │
|
||
│ ├── personaPassword(email) — HMAC-SHA256 │
|
||
│ ├── loginAndGetCookies — POST /auth/login │

|

|
||
./__snapshots__/<spec>/<img>-<project>.png
|
||
```
|
||
|
||
## Adding a flow
|
||
|
||
Copy `flows/home.spec.ts` to `flows/<module>.spec.ts`, change:
|
||
|
||
- `test.use({ personaKey: '…' })` to the right persona
|
||
- the `goto('/')` path
|
||
- the screenshot filename
|
||
|
||
Run `pnpm test:update` once to capture the baseline, commit the new PNG, done. CI diffs on every future run.
|
||
|
||
## Design notes
|
||
|
||
- **No webServer in config**: the suite runs against the *running* stack, not a hermetic one. That's the point — we want to catch regressions in the app that real users would see, not just the test build. If the stack is down, all tests fail loud with a descriptive login error.
|
||
- **API-login, not form-login**: the login UI is tested elsewhere; re-driving it per persona × per spec would add minutes to every run with no signal.
|
||
- **Two viewports, one browser**: `desktop` (1440×900 Chrome) + `mobile` (Pixel 5). Enough to catch most layout regressions without quadrupling the baseline count. Add `iPad` / `webkit` after the suite has settled.
|
||
- **Diff threshold 0.2%**: tight enough to catch real regressions, loose enough to ignore antialiasing noise. Tune if false positives emerge.
|
||
- **`animations: 'disabled'`**: Playwright pauses CSS animations for the screenshot, so transitions don't bleed into diffs.
|
||
- **Live timestamps hidden**: any element with `data-testid="live-time"` gets `visibility: hidden` before the screenshot. Add that testid to clock/relative-time components.
