## Why
Bank connection via Enable Banking is a critical flow that must keep
working in **both onboarding and settings**, including reconnecting an
expired consent. This adds regression coverage so it never silently
breaks.
## What
Two complementary layers:
### 1. CI regression — mocked Pest browser tests
`tests/Browser/BankConnectionFlowTest.php` drives the full UI →
`authorize` → `callback` → account mapping → sync flow for all three
scenarios, with the banking provider faked
(`tests/Support/FakeBankingProvider.php`). Deterministic, no external
calls.
- ✅ connect from onboarding (accounts auto-created)
- ✅ connect from settings (+ account mapping)
- ✅ reconnect an expired connection (re-matches accounts by IBAN)
**Runs on CI** in the existing `browser-tests` job (distributed across
shards automatically as a new test; `shards.json` timing entry will be
added next time `update-browser-shards` runs).
### 2. Live-sandbox verification — standalone Playwright script
`tests/Browser/live/connect-bank.mjs` runs the same three flows against
the **real Enable Banking sandbox** (Banco de Sabadell + BBVA) via the
dev server, for on-demand / nightly checks. Backed by a local-only
helper command `app/Console/Commands/E2eBankingFixtureCommand.php`.
**Does not run on CI** (needs the dev server, live sandbox, and
secrets). See `tests/Browser/live/README.md`.
#### Why the live flow can't be a normal Pest test
Enable Banking only redirects to the fixed registered URI
(`https://whisper.money.local/open-banking/callback`). A
`RefreshDatabase` Pest test runs an ephemeral server on a random port
with a transactional DB the external redirect can never reach. The
script instead drives the persistent dev server, captures the
`code`+`state` the bank redirects with, and replays the callback against
the dev server (the callback is stateless — keyed by `state_token`).
## Verification
- Mocked Pest tests: **3 passing**.
- Live script: **all 3 scenarios PASS** against the real sandbox
(Sabadell → 5 accounts + 328 tx synced; BBVA onboarding → 7 accounts;
expired → reconnect refreshes `valid_until` and retains accounts).
- `pint --test`, eslint, prettier clean.
> Note: while verifying locally, the dev DB was missing the
`state_token` migration (`2026_06_05_185212`), which made
`/open-banking/authorize` 500. Worth confirming it's applied in other
environments.
