Unit Testing

Encodes validation patterns for robotics simulation code (ROS 2, Gazebo, Isaac Sim). Ensures code examples are testable, safe, and follow simulation-first pedagogy. Validates Python syntax, ROS 2 patterns, URDF/SDF markup, and troubleshooting completeness.

RESTful API 설계, Request/Response DTO, @Valid 검증. MockMvc 금지, TestRestTemplate 필수. /kb-rest-api 명령 시 자동 활성화.

Use when writing tests or implementing code. Defines RED-GREEN-REFACTOR cycle and test execution workflow.

Complete development setup: scaffolding, TypeScript, testing, CI/CD, Docker, deployment, and best practices

Run TUnit tests with Playwright. Use when user asks to run tests, execute tests, or check if tests pass.

Extract and capture screenshots of specific UI elements mentioned in QA test procedures. Use when creating visual references for test steps to show exactly what buttons, fields, and components look like.

Guide experienced developers on test structure, patterns, assertions, and test doubles for effective test-driven development

Lightning-fast quality check using parallel command execution. Runs theater detection, linting, security scan, and basic tests in parallel for instant feedback on code quality.

Analyze feature documentation (PDF, markdown, or requirements) and create comprehensive implementation plans for DevPortfolio Portfolio app features. Use when asked to create implementation plans, analyze feature requirements, plan new sections, or design features for apps/portfolio/. Generates detailed phase-by-phase plans with entity design, core layer, components, hooks, styling, i18n, and testing checklists.

Production-tested patterns for fault-tolerant browser audio with zero-lag rapid-fire support. Use when implementing sound effects, background music, voice feedback, or any audio playback in web applications. Covers AudioContext singleton, preloading, cloneNode for rapid-fire, autoplay handling, and Web Audio API effects.

Use this skill immediately when the user mentions merge conflicts that need to be resolved. Do not attempt to resolve conflicts directly - invoke this skill first. This skill specializes in providing a structured framework for merging imports, tests, lock files (regeneration), configuration files, and handling deleted-but-modified files with backup and analysis.

Interact with and test local web apps using Playwright.

Automatically applies when reviewing code. Ensures structured review checklist covering correctness, security, performance, maintainability, testing, and documentation.

Test Midnight smart contracts using simulators and unit tests. Use when setting up test environments, writing contract tests, or debugging circuit behavior. Triggers on testing, simulator, unit test, or test framework questions.

Soracom testing standards (unit/contract/E2E, Root vs SAM users, 80% coverage). Use when writing tests or creating test plans.

Complete development lifecycle for GitHub/local issues - branch, implement, test, PR, merge with quality gates

Recognize when user requests new feature implementation and prompt for TDD workflow. Triggers on phrases like "implement", "create function", "add feature", "build a", "write code for". Suggests generating failing tests first.

Automatically applies when creating AI tool functions. Ensures proper schema design, input validation, error handling, context access, and comprehensive testing.

Use when user requests "parallel" commands, running multiple builds/tests simultaneously, or long-running tasks. Use `gob add` instead of parallel Bash tool calls - gob provides job management, output capture, and proper process control.

Detects project type, package manager, and monorepo structure. Returns correct commands for test/build/lint/dev. Run at project initialization and cache results in state. Use before running any build/test commands.
