Test changes

Choose checks for the affected packages and behavior. Use package typecheck scripts, Biome on changed files, and focused tests. Include affected dependents when shared contracts change. For example, run a focused test from the repository root:

pnpm run test packages/fs/watch.test.ts

Broaden verification when shared impact, failures, or unresolved concerns justify it. Before opening a code PR, complete the repository-wide checks required by .github/workflows/ci.yml from the repository root:

pnpm run typecheck
pnpm run lint
pnpm run test

Fix failures caused by the requested change and rerun affected checks. Report unrelated failures. Repeat passing checks only after relevant changes. Scope formatting and autofixes to changed files and review their diffs; the root format and lint:fix scripts rewrite files across the repository.

Check the Frieren UI

For a visible change in platform/frieren, use a short Playwright CLI smoke check. Do not add a full end-to-end test unless the user asks for one.

Start the app from the repository root:

pnpm run dev

In a second shell, open the authenticated test session:

pnpm --filter frieren run verify:ui

This command creates or reuses a Clerk development user, signs in, and opens http://localhost:5173 in the frieren session. Inspect only the changed flow. Use commands such as:

pnpm --filter frieren exec playwright-cli -s=frieren snapshot
pnpm --filter frieren exec playwright-cli -s=frieren console
pnpm --filter frieren exec playwright-cli -s=frieren requests
pnpm --filter frieren exec playwright-cli -s=frieren close

Use fill and click as needed.

Check the sandbox reducer frame

After a change to sandboxWorkerSource in packages/app/sandbox.ts or the reducer frame in platform/frieren/src/apps/sandbox.worker.ts, run:

pnpm --filter frieren run verify:sandbox

This check confirms that the classic reducer Worker loads and answers the protocol in real browsers. If a required Playwright browser is missing, install it with:

pnpm --filter frieren exec playwright install chromium firefox webkit
