run-dashboard-e2e-local-changes

When to Use

Use when validating local dashboard changes via the Docker browser-E2E harness (npm run test:e2e), or when a new/edited E2E spec mysteriously fails to see your code. The harness's test-up.sh runs docker compose up WITHOUT --build, so it reuses a cached pi-dashboard:local image and your committed changes are NOT in the running container until you rebuild.

Procedure

1. Rebuild the image from current source FIRST: docker compose -f docker/compose.yml build (Dockerfile COPYs packages/ + runs npm install && npm run build → bakes local source). Slow (~4-6 min: apt + npm install + build).
2. Run the suite (or one spec): npm run test:e2e or npx playwright test <spec-name>. Playwright globalSetup runs docker/test-up.sh (compose up, reuses the just-built image), waits for /api/health 200, runs specs at http://localhost:18000, globalTeardown runs test-down.sh (removes container+volumes+network).
3. Fast iteration after a build: PW_E2E_USE_RUNNING=1 npm run test:e2e attaches to an already-running harness and skips teardown.
4. Spec conventions: select existing app data-testids (helpers/index.ts TESTIDS map for static keys; page.getByTestId(...-${id}) for dynamic). Navigate Settings→Packages via page.goto('/settings/packages') then wait for testid package-browser; RecommendedExtensions card renders inside it (non-collapsible Section).

Pitfalls

• Under heavy host load (multiple worktree test containers + many pi sessions), the managed npm run test:e2e globalSetup can blow its 180s health cap even with a pre-built image. Robust fallback = manual up + attach mode for a SINGLE spec: (1) pre-build the per-worktree tag; (2) bring the container up yourself WITH the seed env PI_E2E_SEED=1 PI_TEST_PEERS=both ./docker/test-up.sh -d (writes .pi-test-harness.json with the derived port); (3) poll curl :$PORT/api/health until 200; (4) run PW_E2E_USE_RUNNING=1 PW_E2E_PORT=$PORT PW_CHANNEL=chrome npx playwright test <spec> (skips globalSetup build + teardown); (5) ./docker/test-down.sh after.
• MANDATORY seed env on manual test-up.sh: without PI_E2E_SEED=1 the onboarding "Add folder" CTA renders DISABLED (title="Set up credentials first", gated on providersReady), so spawnFreshGitSession/pinDirectory time out at 60s. The managed globalSetup sets PI_E2E_SEED=1 + PI_TEST_PEERS=both; a hand-rolled test-up.sh -d does NOT — pass them explicitly.
• Specs needing global roles/models data (e.g. roles-custom.spec.ts asserting builtinRoleNames-driven UI) MUST spawn a live session first: the client only sends request_roles/request_models through the first non-ended session (App.tsx), so with zero sessions the roles panel never receives builtinRoleNames and renders its flat back-compat layout.

Verification

1. docker compose -f docker/compose.yml build ends with Image pi-dashboard:local Built.
2. npm run test:e2e prints N passed and the teardown removes the pi-dash-test-* container/volumes/network.
3. A spec asserting your new UI (e.g. recommended-requires) passes only after the rebuild, not before.
