Created by currents.dev, this skill equips coding agents with reference guides for Playwright development. It maps out testing activities to specialized files covering test suite architecture, locator strategies, custom fixtures, and Page Object Model design. The agent pulls these references during test creation, component verification, or API mocking.
The guides handle advanced browser automation scenarios. They include patterns for clock mocking, file operations, WebSocket traffic, and axe-core accessibility checks. Other sections detail mobile emulation with touch interactions, along with testing Electron desktop apps and browser extensions.
Because the repository contains architectural documentation rather than an automated test runner, Playwright must already be installed in your project. Check your test runner setup first so the agent can apply these patterns directly to your code.
What it helps with
- structure end-to-end tests with Page Object Model
- fix flaky tests and locator waiting issues
- mock GraphQL endpoints and simulate clock time
- configure accessibility testing with axe-core
Example prompts for the agent
- Refactor our authentication tests using Playwright Page Object Model
- Show me how to mock GraphQL requests following Playwright best practices
- Debug this flaky test involving file uploads and locator timeouts

Validation Loop After writing or modifying tests: 1. **Run tests**: `npx playwright test --reporter=list` 2. **If tests fail**: - Review error output and trace (`npx playwright show-trace`) - Fix locators, waits, or assertions - Re-run tests 3. **Only proceed when all tests pass** 4. **Run multiple times** for critical tests: `npx playwright test --repeat-each=5`
