Rules

Playwright · balanced balanced

- Use Playwright for E2E, integration, and browser tests simulating user interactions.

- Write tests in TypeScript for type-safe selectors, actions, and assertions.

- Run tests via `npx playwright test` or npm scripts for local and CI execution.

- Test across Chromium, Firefox, and WebKit browsers for cross-browser reliability.

- Configure playwright.config.ts with baseURL, viewport sizes, and timeouts to match production environments and reduce flakiness.

- Leverage auto-waiting features and expect() assertions for robust, low-maintenance tests without manual sleeps.

- Enable tracing, screenshots, and video capture on failure for efficient debugging of intermittent issues.

- Use getByRole, getByText, or getByTestId locators prioritizing accessibility over fragile selectors.
