概要
This skill empowers developers to architect, implement, and maintain professional-grade end-to-end testing environments. It provides standardized patterns for popular frameworks like Playwright and Cypress, covering essential strategies such as the Page Object Model (POM), network interception, custom fixtures, and intelligent waiting mechanisms. Whether you are setting up a new CI/CD pipeline, debugging flaky tests, or integrating accessibility and visual regression checks, this skill offers the blueprints needed to build high-confidence test suites that mirror real user behavior and catch critical bugs before they reach production.
