What problem does it solve? Building and maintaining a comprehensive web test suite requires juggling many tools, patterns, and checklists across unit, integration, E2E, load, security, visual, and accessibility testing. This Skill consolidates proven testing strategies, ready-to-run scripts, and reference guides so you can set up, execute, and analyze tests without researching each domain from scratch. ## Core Features & Use Cases - Playwright Project Initialization: Run the init script to scaffold a best-practice Playwright setup with config, auth fixtures, example tests, and optional component testing. - Unified Test Result Analysis: Parse Playwright JSON, Vitest JSON, and JUnit XML results into a single summary with pass rates, failure details, and markdown output for CI reports. - Domain Reference Guides: Access 20+ focused references covering testing pyramids, contract testing with Pact/MSW, database testing with Testcontainers, Core Web Vitals, OWASP security checks, WCAG accessibility audits, mobile gestures, and flakiness mitigation. - Use Case: Before a release, run the pre-release checklist, execute cross-browser Playwright suites, audit accessibility with axe-core, measure LCP/CLS/INP with Lighthouse CI, and merge sharded CI reports into one summary. ## Quick Start Ask the AI to initialize a Playwright testing setup for your project and generate an E2E test suite for your login flow.
