/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

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

Workflow

  • Read e2e/CLAUDE.md before writing tests.
  • Implement or update tests with user-centric assertions.
  • Improve accessibility markup when it enables stronger locators.
  • 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.
