Testing

We use a layered approach:

• fast checks (lint, unit tests)
• smoke tour (manual-ish)
• optional e2e (Playwright)

Scripts (expected)

In package.json:

• npm run dev start server
• npm test run unit tests (can be minimal early)
• npm run lint lint
• npm run e2e run browser tests (optional early)

Smoke tour (10 steps)

This should be doable by an agent in a browser and by a human in 2–3 minutes.

1. Load app, confirm no console errors.
2. Select a web (or load demo web).
3. Click a node in graph, verify bio updates.
4. Hover a neighbor in graph, verify preview state (no URL change).
5. Click neighbor, verify URL updates and selection commits.
6. Scrub timeline (or set time range), verify graph filters/highlights.
7. Click a map pin (if available), verify selection updates.
8. Use search to find a node, preview then commit.
9. Create a new node connected to current node, verify it appears.
10. Export web, import it back, verify nodes/links preserved.

E2E tests (optional early)

Start with one Playwright smoke test that performs steps 1–6.

Definition of done (testing)

• [ ] Smoke tour steps are kept current as features change.
• [ ] Every PR runs at least lint + smoke tour.
