Jest testing patterns, factory functions, mocking strategies, and TDD workflow. Use when writing unit tests, creating test factories, or following TDD red-green-refactor cycle.
This skill provides expert-level guidance for Test-Driven Development (TDD) in VS Code extension development following t-wada methodology. Use when writing tests before implementation, creating comprehensive test suites, implementing Red-Green-Refactor cycles, or improving test coverage for extension components like WebViews, terminal managers, and activation logic.
Refactor code after tests pass. The "Refactor" phase of Red-Green-Refactor.
Testing philosophy and practices. This skill should be used when writing tests, designing test strategies, or reviewing test code. Use proactively when discussing TDD, red-green-refactor, test doubles, mocks, stubs, fakes, RSpec, Jest, pytest, unit tests, integration tests, test coverage, or test-first development. (user)
Implement features using Test-Driven Development (TDD) with Red-Green-Refactor cycle.
Guide users through TDD and TCRDD (Test && Commit || Revert + Test Driven Development). Use this skill whenever a user mentions TDD, test-driven development, writing tests before code, red-green-refactor cycles, or unit testing workflows. Also trigger when a user asks about TCRDD, TCR, "test commit revert", "git gamble", or wants a strict TDD workflow with automatic commits and reverts. Trigger when the user asks to implement a feature, fix a bug, or write a class/function and mentions tests, TDD, or "test first". If the user shares code and asks for a review with any testing angle, consult this skill.
TDD-based code simplification that preserves behavior through tests. Use Red-Green-Refactor cycles to simplify code one test-verified change at a time. **DISTINCT FROM**: General code review or AI rewriting—this skill requires existing tests and only proceeds when tests confirm behavior is preserved. **PROACTIVE**: Auto-invoke when test-covered code has complexity (functions >50 lines, high cyclomatic complexity, duplication) and user wants to simplify it safely. Trigger phrases: 'clean up code', 'make code simpler', 'reduce complexity', 'refactoring help'. **NOT FOR**: Adding features or fixing bugs—use /tdd skill instead.
Android Test-Driven Development standards. Enforces Red-Green-Refactor cycle, test pyramid (70/20/10), layer-specific testing strategies, and CI integration. Use when building or reviewing Android apps with TDD methodology.
Use when creating or editing any prompt (commands, hooks, skills, subagent instructions) to verify it produces desired behavior - applies RED-GREEN-REFACTOR cycle to prompt engineering using subagents for isolated testing
Strict Red-Green-Refactor workflow for robust, self-documenting code. Discovers project test setup via codebase exploration before assuming frameworks. Use when: (1) Implementing new features with test-first approach, (2) Fixing bugs with reproduction tests, (3) Refactoring existing code with test safety net, (4) Adding tests to legacy code, (5) Ensuring code quality before committing, (6) When tests exist but workflow unclear, or (7) When establishing testing practices in a new project. Triggers: test, tdd, red-green-refactor, failing test, test first, test-driven, write tests, add tests, run tests.
단일 태스크의 RED-GREEN-REFACTOR TDD 루프를 ping-pong 방식으로 실행합니다. .tdd-sessions/에서 활성 세션 파일을 읽어 현재 태스크를 찾고, 개발자와 함께 전체 사이클을 진행하며 (테스트 작성과 구현을 번갈아가며), 완료 시 세션 파일을 업데이트합니다. 세션 파일을 생성하려면 먼저 /tdd-plan을 실행하세요.
Test-Driven Development methodology enforcing RED-GREEN-REFACTOR cycle. Use for writing tests first, preventing regression, and ensuring code correctness. Based on obra/superpowers.
