Unit Testing

Testing methodologies, test-driven development (TDD), unit and integration testing, and testing best practices across multiple frameworks. Use when the user needs to write tests, implement TDD, or improve test coverage and quality.

Guide for implementing Cloudflare Browser Rendering - a headless browser automation API for screenshots, PDFs, web scraping, and testing. Use when automating browsers, taking screenshots, generating PDFs, scraping dynamic content, extracting structured data, or testing web applications. Supports REST API, Workers Bindings (Puppeteer/Playwright), MCP servers, and AI-powered automation. (project)

Searching internet for technical documentation using llms.txt standard, GitHub repositories via Repomix, and parallel exploration. Use when user needs: (1) Latest documentation for libraries/frameworks, (2) Documentation in llms.txt format, (3) GitHub repository analysis, (4) Documentation without direct llms.txt support, (5) Multiple documentation sources in parallel

Operate E2B agent sandboxes using the CLI. Use when user needs to run code in isolation, test packages, execute commands safely, or work with binary files in a sandbox environment. Keywords: sandbox, e2b, isolated environment, run code, test code, safe execution.

Write focused pytest tests as standalone functions (one test per function), avoiding test classes.

Intelligent skill router that analyzes user requests and automatically dispatches to the most appropriate skill(s) or zen-mcp tools. Routes to zen-chat for Q&A, zen-thinkdeep for deep problem investigation, codex-code-reviewer for code quality, simple-gemini for standard docs/tests, deep-gemini for deep analysis, or plan-down for planning. Use this skill proactively to interpret all user requests and determine the optimal execution path.

Clear Unity console logs via uloop CLI. Use when you need to: (1) Clear the console before running tests, (2) Start a fresh debugging session, (3) Clean up log output for better readability.

Control Unity Editor play mode via uloop CLI. Use when you need to: (1) Start play mode for testing, (2) Stop play mode after testing, (3) Pause play mode for debugging.

Compile Unity project via uloop CLI. Use when you need to: (1) Verify C# code compiles successfully after editing scripts, (2) Check for compile errors or warnings, (3) Validate script changes before running tests.

Execute Unity Test Runner via uloop CLI. Use when you need to: (1) Run unit tests (EditMode tests), (2) Run integration tests (PlayMode tests), (3) Verify code changes don't break existing functionality.

Sample hello world tool via uloop CLI. Use when you need to test the MCP tool system or see an example of custom tool implementation.

Collaborative documentation and test code writing workflow using zen mcp's clink to launch gemini CLI session in WSL (via 'gemini' command) where all writing operations are executed. Use this skill when the user requests "use gemini to write test files", "use gemini to write documentation", "generate related test files", "generate an explanatory document", or similar document/test writing tasks. The gemini CLI session acts as the specialist writer, working with the main Claude model for context gathering, outline approval, and final review. For test code, codex CLI (also launched via clink) validates quality after gemini completes writing.

Provides automated refactoring suggestions and complexity reduction strategies using PMAT(Pragmatic AI Labs MCP Agent Toolkit). Use this skill when:- User requests code refactoring, optimization, or improvement- Complexity analysis reveals high-complexity functions (cyclomatic > 10)- Code review identifies maintainability issues- Technical debt needs to be addressed systematically- Preparing legacy code for modernizationSupports 25+ languages with data-driven refactoring recommendations based on complexity metrics,mutation testing results, and industry best practices (Fowler's refactoring catalog).

World-class prompt powerhouse that generates production-ready mega-prompts for any role, industry, and task through intelligent 7-question flow, 69 comprehensive presets across 15 professional domains (technical, business, creative, legal, finance, HR, design, customer, executive, manufacturing, R&D, regulatory, specialized-technical, research, creative-media), multiple output formats (XML/Claude/ChatGPT/Gemini), quality validation gates, and contextual best practices from OpenAI/Anthropic/Google. Supports both core and advanced modes with testing scenarios and prompt variations.

Comprehensive Test Driven Development guide for engineering subagents with multi-framework support, coverage analysis, and intelligent test generation

Expert knowledge for developing the SRTD codebase itself. Use when implementing features, fixing bugs, understanding architecture, or writing tests for SRTD internals. NOT for end users of srtd CLI.

Test Ark Dashboard with Playwright and create PRs with screenshots. Use when testing dashboard UI, taking screenshots for PRs, or reviewing dashboard changes.

Test changes in a dedicated Emacs session. Good for validating behavior and UI results.

Enforces TDD order in TASKS.md - Tests MUST be marked complete before Implementation tasks. Blocks violations in real-time.

Research-driven investigation skill for validating solutions and exploring documentation. Never ask questions you can answer yourself through research. Use WebFetch, WebSearch, and testing to validate ideas before presenting them. Deliver concrete, tested recommendations with evidence.
