Use when testing UI features, service panels, or visual behavior in the PizzaPi sandbox using a headless browser. Use when verifying new UI components work end-to-end before merging.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# Testing Sandbox UI with Playwright ## Overview The PizzaPi sandbox (`packages/server/tests/harness/sandbox.ts`) spins up a full server with mock sessions, runners, and services. Combined with `playwright-cli`, you can drive a real browser against it to verify UI features work end-to-end — login, navigation, service panels, iframes, etc. ## When to Use - Verifying new UI components render correctly in the full app - Testing service panel iframe loading through the tunnel proxy - Checking auth flows (login, session management) - Visual regression checks before merging UI branches - Any time you need to confirm "does this actually work in a browser?" ## Quick Reference | Step | Command | |------|---------| | Start sandbox | `screen -dmS sandbox bash -c 'cd packages/server && exec bun tests/harness/sandbox.ts --headless --redis=memory > /tmp/sandbox-out.log 2>&1'` | | Wait for ready | `grep "Sandbox ready" /tmp/sandbox-out.log` | | Extract UI URL | `grep "UI (HMR)" /tmp/sandbox-out.log` | | Open browser | `playwright-cli open <URL>` | | Get element refs | `playwright-cli snapshot` then read the `.yml` file | …

How to install
mdr add pizzaface/pizzapi/testing-sandbox-ui@sha256:fc71ab8ae98ebe32The line at the top of this page pins the label git:20260325.fcee38c, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
