概要
This skill provides specialized guidance for implementing advanced end-to-end (E2E) testing architectures using Playwright and Cypress. It focuses on creating deterministic, maintainable tests by leveraging patterns like the Page Object Model (POM), custom fixtures, and intelligent waiting strategies. It helps developers move beyond basic scripts to build enterprise-ready suites that include network mocking, visual regression testing, and accessibility audits, ensuring critical user journeys remain functional across all browsers and devices.
