zeekay f627f20da1 e2e: Playwright smoke + multi-tenant specs for tenant bridge SPA
Env-parametric specs covering bridge.lux.network (and bridge.zoo.network
+ future tenants). Mirrors the wider Lux e2e env routing convention:

  E2E_ENV=local (default) → http://localhost:3001 (auto-boots vite preview)
  E2E_ENV=dev             → https://bridge.lux-dev.network
  E2E_ENV=test            → https://bridge.lux-test.network
  E2E_ENV=main            → https://bridge.lux.network
  BRIDGE_TENANT=zoo       → https://bridge.zoo.network (mainnet only)

smoke.spec.ts (6 cases, ~16s):
  1. Renders, title matches brand, SVG brand logo from @luxfi/logo
  2. From-chain selector has ≥ 2 options
  3. From-asset selector has ≥ 2 options after switching to Ethereum
     (default chain Lux only has the native LUX asset)
  4. Connect-wallet button visible + clickable (no real wallet connect)
  5. Typing an amount updates the "You receive" estimate via useSwap
  6. Production gate: served HTML + JS bundles free of `DEADBEEF`
     (the dev-only stub MPC display address)

multi-tenant.spec.ts (skips unless E2E_ENV=main):
  - For each tenant in the registry, probe DNS, navigate, assert
    document.title and the --brand-primary CSS variable set by
    applyBrandMetadata reflect the tenant's pinned brand block.

Playwright config auto-boots `vite preview` on :3001 from app/bridge/
when E2E_ENV=local, so `pnpm test:smoke` is one-step after `pnpm build`.
README documents the build prereq and the runner contract.

Out of scope (TODOs in code):
  - Real wallet connect (Playwright wallet mocking is a separate PR)
  - Real backend swap submit (prod backend not reliably reachable from CI)
  - Visual regression / screenshot diffs (separate PR)

# bridge e2e
Playwright smoke + multi-tenant specs for the `@luxfi/bridge` tenant SPA.
One spec, four environments (`local` / `dev` / `test` / `main`). Mirrors the
env-parametric pattern from the wider Lux e2e infra.
## Layout
```
e2e/
├── package.json minimal Playwright deps
├── playwright.config.ts env-aware base URL + auto-boot vite preview on local
├── tsconfig.json
├── tests/
│ ├── smoke.spec.ts render, brand, selectors, wallet button, quote, prod gate
│ └── multi-tenant.spec.ts cross-tenant brand-routing assertions (E2E_ENV=main only)
└── README.md this file
```
## Quick start (local)
```bash
# 1. From repo root, install workspace deps once.
pnpm install
# 2. Build the tenant SPA — `vite preview` requires a built dist/.
cd app/bridge && pnpm build
# 3. Install browsers + run.
cd ../../e2e
pnpm install
pnpm install:browsers # one-time chromium download
pnpm test:smoke # boots `vite preview` on :3001 automatically
```
The `webServer` block in `playwright.config.ts` boots `pnpm preview` on `:3001`
from `app/bridge/dist/`. If you want to point at `vite dev` instead, set
`E2E_BASE_URL=http://localhost:3001` and run `pnpm --filter @luxbridge/lux-tenant dev`
in a separate shell first.
## Run against deployed envs
```bash
E2E_ENV=dev pnpm test:smoke # https://bridge.lux-dev.network
E2E_ENV=test pnpm test:smoke # https://bridge.lux-test.network
E2E_ENV=main pnpm test:smoke # https://bridge.lux.network
```
Tenant override:
```bash
BRIDGE_TENANT=zoo E2E_ENV=main pnpm test:smoke
# → https://bridge.zoo.network
```
Add custom base URL (e.g. PR preview deploy):
```bash
E2E_BASE_URL=https://pr-123--lux-bridge.preview.network pnpm test:smoke
```
## Multi-tenant spec
```bash
E2E_ENV=main pnpm test:multi-tenant
```
Runs only against `E2E_ENV=main`. Each tenant (Lux, Zoo, future) probes the
production DNS first and skips if the deployment isn't live. Asserts:
- `<title>` contains the tenant brand name (`Lux Bridge`, `Zoo Bridge`)
- `<html>` has `--brand-primary` set to the tenant's pinned hex color
Add a new tenant by appending one entry to `TENANTS` in
`tests/multi-tenant.spec.ts` — no other changes needed.
## What this does NOT cover
- **Real wallet connect** — the stub `useWallet` resolves to a dev-only display
address (`0xLUXBRIDGE…DEADBEEF`) gated behind `import.meta.env.DEV`. Real
threshold-MPC wallet integration (Phase 3 R3) needs Playwright wallet
mocking, which is heavy enough to warrant its own PR.
- **Real backend swap submit** — the prod bridge API isn't always reachable
from CI (rate-limited / behind WAF). Add a separate `tests/backend.spec.ts`
with a fixture wallet + signed quote when the test harness is ready.
- **Visual regression / screenshots** — see follow-up PR.
## CI
```yaml
- name: bridge smoke
run: |
pnpm install --frozen-lockfile
cd app/bridge && pnpm build
cd ../../e2e && pnpm install && pnpm install:browsers
E2E_ENV=${{ matrix.env }} pnpm test:smoke
```
Recommended matrix: `[dev, test]`. Mainnet smoke is opt-in via
`workflow_dispatch` to avoid hammering production on every push.
## Conventions
- One file per concern: `smoke.spec.ts` is the standard tenant render check,
`multi-tenant.spec.ts` is the cross-tenant brand contract.
- No hostnames in spec bodies — `playwright.config.ts` owns env routing.
- No shared auth state — bridge mainnet is unauthenticated (wallet connect
is purely client-side); no need for `storageState`.
- Selectors prefer `aria-label` over visible text, matching the actual
`ChainSelector` / `AssetInput` / `WalletConnect` component contracts in
`pkg/bridge/src/app/components/`.
