React component and hook testing patterns with Testing Library and Vitest. Use when writing tests for React components, custom hooks, or data fetching logic. Covers component rendering tests, user interaction simulation, async state testing, MSW for API mocking, hook testing with renderHook, accessibility assertions, and snapshot testing guidelines. Does NOT cover E2E tests (use e2e-testing) or TDD workflow enforcement (use tdd-workflow).
Unified testing skill — TDD workflow, unit/integration patterns, E2E/Playwright strategies. Replaces tdd-workflow + testing-patterns + webapp-testing.
Use when implementing any feature or bugfix, before writing implementation code
Implement comprehensive testing strategies using Jest, Vitest, and Testing Library for unit tests, integration tests, and end-to-end testing with mocking, fixtures, and test-driven development. Use when writing JavaScript/TypeScript tests, setting up test infrastructure, or implementing TDD/BDD workflows.
Test-driven development with red-green-refactor loop. Use when user wants to build features or fix bugs using TDD, mentions "red-green-refactor", wants integration tests, or asks for test-first development.
SPARC (Specification, Pseudocode, Architecture, Refinement, Completion) comprehensive development methodology with multi-agent orchestration
Test-driven development workflow with test generation, coverage analysis, and multi-framework support
GLSL shader programming for JARVIS holographic effects
Expert guidance for writing fast, maintainable Minitest tests in Rails applications. Use when writing tests, converting from RSpec, debugging test failures, improving test performance, or following testing best practices. Covers model tests, policy tests, request tests, system tests, fixtures, and TDD workflows.
テスト駆動開発（TDD）ワークフローを実行するスキル。 使用タイミング: (1) 新機能の実装開始時 (2) バグ修正時 (3) リファクタリング前 (4) 「テストから書いて」と言われた時 (5) 品質重視の実装が必要な時。 トリガー例: 「TDDで実装して」「テスト駆動で」「テストから書いて」 「RED-GREEN-REFACTORで」「UserServiceのテストを書いて」
Comprehensive TDD patterns and practices for all programming languages, eliminating redundant testing guidance per agent.
Test-driven development workflow — write failing tests first, implement minimum code, run full suite, commit. Use when implementing features, fixing bugs, or adding test coverage. Includes mock bootstrap phase for projects with mockReset:true.
