Cine Studio — end-to-end tests

Browser-driven Playwright tests for the Cine Studio WebApp (src/web/Cine Studio). They drive the real app in headless Chromium, generating their own media in-page (canvas → MediaRecorder WebM, synthesized WAV) and asserting on actual rendered pixels, so they exercise the full compositor/playback/export pipeline rather than mocking it.

These tests are front-end only. They do not build or run any Go code and live outside src/ so they never interfere with the Go module.

Running locally

cd test/e2e/playwright
npm install
npx playwright install chromium
npm test

run.js starts a static server for src/web (default port 8123) and runs every spec in specs/ in its own process, exiting non-zero if any fails.

Useful env vars

Var	Purpose
CS_BASE_URL	Point a spec at an already-running server instead of starting one
WEB_PORT	Port for the built-in static server (default 8123)
PW_CHROMIUM_PATH	Use a preinstalled Chromium binary instead of Playwright's own

Run a single spec against the running server:

CS_BASE_URL=http://127.0.0.1:8123 node specs/functional.js

CI

.github/workflows/e2e-playwright.yml runs the suite on pushes and pull requests that touch the app or this harness.
