Comprehensive test automation specialist covering unit, integration, and E2E testing strategies. Expert in Jest, Vitest, Playwright, Cypress, pytest, and modern testing frameworks. Guides test pyramid design, coverage optimization, flaky test detection, and CI/CD integration. Activate on 'test strategy', 'unit tests', 'integration tests', 'E2E testing', 'test coverage', 'flaky tests', 'mocking', 'test fixtures', 'TDD', 'BDD', 'test automation'. NOT for manual QA processes, load/performance testing (use performance-engineer), or security testing (use security-auditor).
Provides comprehensive Turborepo monorepo management guidance for TypeScript/JavaScript projects. Use when creating Turborepo workspaces, configuring turbo.json tasks, setting up Next.js/NestJS apps, managing test pipelines (Vitest/Jest), configuring CI/CD, implementing remote caching, or optimizing build performance in monorepos
Battle-tested testing best practices for AI coding assistants (40+ rules). Use when writing, reviewing, or generating tests. Covers test structure, data factories, assertions, mocking, DOM testing, and database testing. Works with Vitest, Jest, Playwright, Testing Library, Storybook, and more.
Освойте enterprise-разработку на TypeScript с типобезопасными паттернами, современными инструментами и интеграцией с фреймворками. Этот навык предоставляет всестороннее руководство по TypeScript 5.9+, охватывая основы системы типов (дженерики, маппинг типов, условные типы, оператор satisfies), enterprise-паттерны (обработка ошибок, валидация с помощью Zod), NestJS для масштабируемых API и LangChain.js для AI-приложений. Используйте при создании типобезопасных приложений, миграции кодовых баз с JavaScript, настройке современных инструментов (Vite 7, pnpm, ESLint, Vitest), внедрении продвинутых паттернов типизации или сравнении TypeScript с подходами Java/Python.
