# End-to-end browser tests

Playwright, driving the portal and the backoffice in a real browser against a
real API and a real database.

```bash
# from emaui/
npx nx e2e @ema-platform/e2e            # or: npx playwright test --config apps/e2e/playwright.config.ts
npx playwright test --config apps/e2e/playwright.config.ts --headed --debug
npx playwright show-report ../../dist/e2e-report
```

## What it runs against

Nothing shared with your own dev stack. The suite starts its own servers, on its
own ports, against its own database:

| | port | notes |
|---|---|---|
| API | 3011 | `node dist/main.js` with explicit env |
| Portal | 4302 | `vite build --mode e2e` then `vite preview` |
| Backoffice | 4303 | same |
| Database | — | `ema_e2e` |

This is deliberate. A developer's stack is usually already up on 3000/3001/4201,
and `dev/start.sh` **rewrites** `emaapi/apps/server/emaapi/.env` and the apps'
`.env.local` on every run — a suite that read those files would point at
whichever stack was started last. The API is launched with `DATABASE_NAME`,
`PORT` and the payment flags passed directly, and the frontends are built with
`--mode e2e`, which picks up `apps/*/.env.e2e.local` (higher precedence than
`.env.local`, so your own config is left alone).

`vite preview` on a production build rather than `nx serve`, because Nx
serialises `serve` targets per project: with your dev portal already running,
a second `nx serve @ema-platform/portal` waits forever on the first.

### First-time setup

The E2E database has to exist and be bootstrapped once:

```bash
DB_NAME=ema_e2e ./dev/start.sh      # creates it, migrates, seeds, then starts a stack you can Ctrl-C
```

Afterwards the suite manages its own servers; you do not need `start.sh` again.
Note that this run leaves the shared `.env` files pointing at the E2E database
and its ports — rerun `./dev/start.sh` plain to put them back.

## How it gets its data

- **Accounts are created through the UI.** Every spec signs up its own applicant
  with a timestamped email, and deletes it in `afterEach` (`deleteApplicant`).
  Nothing is shared between specs, so specs can run in any order and the second
  run of the suite behaves exactly like the first.
- **The one-time code is scraped from the API log.** There is no local SMS
  gateway, `iam.user_verifications.verification_code` is argon2-**hashed**, and
  the notification rows it is delivered through carry an empty body — the log
  line is the only plaintext. The API is therefore started with its output teed
  to `/tmp/ema-e2e-api.log`, and `support/api-log.ts` reads codes written after
  a recorded offset. The test still types the real code into the real screen.
  Because the log line names no recipient, matching is by position, which is
  sound only while the suite runs single-worker — hence `workers: 1`.
- **Database reads use `psql`**, shelled out from `support/db.ts`, rather than
  adding a `pg` dependency to the frontend workspace for the sake of a few
  assertions.

## Conventions

- One worker, serial. The officer queue is global state and the log-offset trick
  needs ordering; determinism is worth the wall-clock.
- Assertions are on what the user sees — headings, badges, buttons — with
  database checks only where the point is that something was *persisted*.
- No `waitForTimeout`. Wait for a condition.
- Traces, screenshots and video are retained for failures only.

## Debugging a failure

Playwright writes `test-results/<test>/error-context.md` with a full
accessibility snapshot of the page at the moment it failed — usually enough on
its own. Otherwise `npx playwright show-trace test-results/<test>/trace.zip`.

## Status

Implemented: signup → OTP → operations gate → dashboard, and the empty-state
dashboard. See the parent prompt (`dev/prompts/e2e-browser-tests-prompt.md`) for
the flows still to be written: catalogue filtering, the full application
lifecycle per licence type, officer review, payment bypass, certificate
download, expiry, renewal and reminders.
