概要
This skill provides comprehensive patterns and best practices for establishing high-quality end-to-end (E2E) testing suites. It covers fundamental concepts like the testing pyramid, advanced Playwright techniques including Page Object Models and network mocking, and Cypress-specific patterns like custom commands and interceptors. By utilizing this skill, developers can reduce flakiness in their test suites, integrate visual regression and accessibility checks, and optimize CI/CD pipelines through parallelization and sharding techniques.
