/e2e-test-writing - E2E Test Writing for Hydrogen

Use this skill when implementing or reviewing Playwright E2E tests in this repository.

Syntax

/e2e-test-writing <task>

Examples:

• /e2e-test-writing add recipe coverage for cart drawer quantity changes
• /e2e-test-writing review locator quality in e2e/tests/cart.test.ts

Source of Truth

• Follow e2e/CLAUDE.md for all active test patterns and conventions.
• Do not duplicate large guidance here; keep this skill as the entry point.

Core Expectations

1. Prefer role-based, accessibility-first selectors.
2. Assert user-visible behavior, not implementation details.
3. Wait for visible effects (expect, expect.poll), never arbitrary timeouts.
4. Keep tests isolated and organize shared setup with beforeEach when it improves clarity.
5. Run Playwright tests in headless mode.

Workflow

1. Read e2e/CLAUDE.md before writing tests.
2. Implement or update tests with user-centric assertions.
3. Improve accessibility markup when it enables stronger locators.
4. Run targeted Playwright tests first, then broader suites if needed.

Verification Commands

pnpm exec playwright test --project=skeleton

Use narrower test paths during iteration, then run the appropriate full project suite before finishing.
