Unit Testing

Mandatory best practices and gold standards for Kailash SDK development including absolute imports, parameter passing, error handling, testing policies (NO MOCKING in Tiers 2-3), workflow design, custom node development, security, documentation, and test creation. Use when asking about 'best practices', 'standards', 'gold standards', 'mandatory rules', 'required patterns', 'absolute imports', 'NO MOCKING', 'testing policy', 'error handling standards', 'security best practices', 'documentation standards', or 'workflow design standards'.

pytest fixtures and integration testing patterns for Spark applications, including DataFrame assertions and mock data generation.

Migrate from Vitest 2.x/3.x to 4.x with pool options, coverage config, workspace to projects, and browser mode updates. Use when upgrading Vitest versions or encountering deprecated patterns.

Testing patterns and best practices for unit, integration, and E2E testing.

Send macOS desktop notifications after completing tasks, making significant changes, or before requesting permission. Use for task completion, file modifications, test results, and major milestones.

Generates comprehensive Elixir tests using ExUnit following TDD principles.

Test-Driven Development workflow guide. TODO - This skill is a placeholder for future development. Will cover TDD patterns for Rust, TypeScript, and Tauri apps.

Production-tested setup for AutoAnimate (@formkit/auto-animate) - a zero-config, drop-in animation librarythat automatically adds smooth transitions when DOM elements are added, removed, or moved. This skill shouldbe used when building UIs that need simple, automatic animations for lists, accordions, toasts, or form validationmessages without the complexity of full animation libraries.Use when: Adding smooth animations to dynamic lists, building filter/sort interfaces, creating accordion components,implementing toast notifications, animating form validation messages, needing simple transitions without animation code,working with Vite + React + Tailwind, deploying to Cloudflare Workers Static Assets, or encountering SSR errors withanimation libraries.Keywords: auto-animate, @formkit/auto-animate, formkit, zero-config animation, automatic animations, drop-in animation,list animations, accordion animation, toast animation, form validation animation, lightweight animation, 2kb animation,prefers-reduce

Automatically applies when writing pytest tests. Ensures proper use of fixtures, parametrize, marks, mocking, async tests, and follows testing best practices.

Runs Static Application Security Testing (SAST) using Semgrep. Scans source code for vulnerabilities, security anti-patterns, and OWASP Top 10 issues. Use when user asks to "run SAST", "scan for vulnerabilities", "static analysis", "code security scan", "静的解析", "脆弱性スキャン".

Comprehensive guide for building robust, secure, and efficient CI/CD pipelines using GitHub Actions. Covers workflow structure, jobs, steps, environment variables, secret management, caching, matrix strategies, testing, and deployment strategies.

Build and maintain WPF MVVM patterns using CommunityToolkit.Mvvm for a .NET 8 widget-host app. Use when creating ViewModels, commands, observable state, validation, view bindings, and viewmodel-first navigation behaviors. Avoid Prism and heavy region managers; keep ViewModels testable and UI-agnostic.

This skill teaches the agent how to write and manage tests in the API project. MANDATORY - You MUST read this skill before modifying any test files.

Run, debug, and structure tests for this Go project (unit + integration), including generation prerequisites. Use when changing domain logic, repositories, HTTP handlers, or migrations.

Alpha/beta/RC tagging patterns and GitHub pre-release workflows for managing pre-production releases. Use when creating alpha releases, beta releases, release candidates, managing pre-release branches, testing release workflows, or when user mentions pre-release, alpha, beta, RC, release candidate, or pre-production versioning.

DEPRECATED umbrella Skill (backward compatibility). Use only for cross-cutting orchestration across multiple WebF app tasks when a request spans several capabilities (dev loop + debugging + testing + release). Prefer focused openwebf-app-* Skills.

Use when implementing code during ant-act execution. Enforces RED-GREEN-REFACTORcycle. Triggers: writing code, fixing bugs, adding features, any implementation.Do NOT skip - no production code without failing test first.

Update CLAUDE.md with minimal, concise, targeted edits. Avoid bloat.TRIGGERS - Use this skill when user says:- "update claude.md", "update the claude md"- "sync claude.md", "refresh claude.md"- "edit claude.md", "modify claude.md"- "add to claude.md", "change claude.md"- "update claude.md with X" (explicit content)- Any request to make changes to CLAUDE.md contentTWO MODES:(1) DEFAULT MODE - "update claude.md" → Analyze git changes since last timestamp(2) EXPLICIT MODE - "update claude.md with X" → Add the specific content XCORE PRINCIPLE: Every update must be minimal and concise. Question every line added.Also use when:- User asks to sync CLAUDE.md with recent code changes (default mode)- Adding major dependencies, architecture patterns, or directory changes- Claude repeatedly makes mistakes that a targeted rule could prevent- Post-milestone updates (new APIs, testing patterns, security fixes)- Project standards, workflows, or conventions change

Analyze ANY web project - detect if Web3 DApp, research dependencies via WebSearch, understand business functions from code AND UI screenshots, generate test requirements.

Advanced Python testing strategies with Pytest, covering fixtures, matrix testing with parametrization, and async test architecture. Triggers: pytest, fixtures, parametrize, pytest-asyncio, matrix-testing, yield-fixture.
