name: markdowntown-testing description: Use this when running or adding tests (compile/lint/unit/E2E), updating test utilities, or working with Playwright/visual testing in markdowntown.

Testing + Playwright E2E

When to use

• Adding or updating unit/integration tests.
• Running the required CI checks before commit.
• Designing or debugging Playwright/E2E flows.

Required checks (default workflow)

1. npm run compile
2. npm run lint
3. npm run test:unit

E2E + visual tests

• npm run test:e2e runs Vitest E2E with vitest.e2e.config.ts.
• npm run test:visual runs Playwright visual tests (playwright-visual.config.ts).
• Set E2E_BASE_URL if you need a non-default host.

Workflow guidance

• Prefer small, focused unit tests in __tests__ for components and lib helpers.
• When adding a new user flow, update the E2E narratives so behavior stays aligned.
• If a test fails due to output changes, update snapshots/fixtures and document why.

Guardrails

• Keep tests deterministic; avoid time-based flakiness where possible.
• When documenting QA evidence, use qa-verification.
