# Browser suites

End-to-end checks for Freezmo, driven by Playwright against a **running
production build**. Everything lives in this repo (nothing in `/tmp`), so a
reboot cannot wipe the harness.

## Requirements

- The app is running on `http://127.0.0.1:3207` (`systemctl --user start freezmo`).
- A Chromium build. The suites auto-detect the newest Playwright Chromium in
  `~/.cache/ms-playwright/` (Linux) or `~/Library/Caches/ms-playwright/` (macOS);
  override with `CHROME=/path/to/chrome`.
- `npm install` (dev deps: `playwright-core`, `axe-core`).

## Running

```bash
npm run build && systemctl --user restart freezmo   # fresh build first
npm run test:e2e                 # every suite, in order
npm run test:e2e -- phase1       # only suites whose name contains "phase1"
```

Each suite prints `PASS`/`FAIL` lines and exits non-zero on failure; the runner
prints a per-suite summary at the end.

## Suites

| Suite | Covers |
| --- | --- |
| `regression.mjs` | Library, deck card + menu, study feed to results, homework entry, desktop shell + settings/health panel. |
| `bubbles-test.mjs` | Ice-scene bubbles: stacking/layout contract, the open band (a plain clip, no mask) and a 41-phase sweep that no visible orb or bubble ever touches its edges, keyframes only transform+opacity, rise/sway/scale/fade phases, per-breakpoint counts (5/3/2), phone pacing, reduced motion, parking (hidden tab, unfocused window, dialog scrim), and the cost contract (static blobs, no blend-mode grain, no blur on static glass, no hidden blur under Aero's bake). |
| `mobile-test.mjs` | Five-tab bar at 360/390 × EN/CS × dark/light × reduced motion (labels, targets, no hamburger/drawer), the library ⋯ sheet (Import JSON / New folder), the settings sheet (touch targets, key flow, drag-to-close, backdrop), axe contrast audits. |
| `wizard-test.mjs` | Deck 3-step flow and homework flow, flat action bar, in-page mode switch, the loading lock, abort-on-leave. |
| `native-test.mjs` | Manifest/PWA head, offline banner + disabled generate, share target GET + POST, Back-gesture layers, undo toast, tab re-tap, haptics, draft restore. |
| `i18n-test.mjs` | EN/CS dictionary parity, locale switch, Czech desktop shell, Czech phone tab labels and plurals. |
| `freeze-loading-test.mjs` | The generation loading screen appears immediately, hides the action bar, Cancel returns with the notice. |
| `review-test.mjs` | Smart Review loading feedback under a stalled request, the session end-to-end, mistakes, and the health-probe cache. |
| `phase1-test.mjs` | Backup export/import, persistence row, nudge, encrypted sync (enable/join/push/delete + API validation), usage-limit handling (client + a stub Ollama). |
| `phase2-test.mjs` | Answer history + SRS from a real study run, review/mistakes, stats, exam mode, push reminders hidden without VAPID and validated with it. |
| `phase3-test.mjs` | Check my work (API + phone/desktop UI), follow-ups, guide step explain, turn-into-a-study-deck. |
| `chat-test.mjs` | Chat: streaming API (validation, allowlist, context travel, history window, thinking separation, usage-limit mapping), attachment extraction, entry points, streaming/stop, markdown + KaTeX, model/scope pickers, edit/regenerate, offline, reduced motion, plus history (IDB persistence, reload, rename/search/delete/undo, scope+model memory), assistant actions, the export payload and a two-device sync round-trip. |

## Extra instances

`phase1`, `phase2` and `phase3` start their own `next start` instance with a
stub Ollama (or VAPID keys) on a spare port (3208/3209). Each suite checks the
port is free first and kills the whole process group on exit, so ports do not
leak between suites. Scratch data for the VAPID test lives in `tests/.tmp/`
(gitignored).

## Diagnostics (not part of the run)

`node tests/bubble-perf.mjs [label]` measures the ice-scene frame cost with a
CDP performance trace (rAF frame timing, long tasks, main-thread busy time,
style recalcs) on a 4× throttled phone profile and a 2× desktop profile. It
always exits 0; the numbers are for tuning the bubble count/speed.

`node tests/heat-probe.mjs [webkit|chromium]` (macOS only) measures what an
idle screen actually costs the machine: headed Playwright WebKit and Chromium
on the real display, the browser's CPU, the GPU time of its processes and of
WindowServer, per screen and theme, against an `about:blank` baseline and with
the scene parked. Install the engines once with
`npx playwright-core install webkit chromium` and keep the window in front.
