Testing Claude Skills
3 543 testing skills from 425 authors. They run test suites, check accessibility and catch what broke. Half of them fit into 1 799 tokens or less — that is what one costs your context window when the agent loads it. 404 ship runnable scripts rather than instructions alone. 2 of them cannot work without an MCP server, most often rube. We also found 429 copies of these same skills sitting in other people's repositories — counted once here, not 429 times.

| Validates that code actually works through sandbox testing, execution verification, and systematic debugging. Use this skill after code generation or modification to ensure functionality is genuine rather than assumed. The skill creates isolated test environments, executes code with realistic inputs, identifies bugs through systematic analysis, and applies best practices to fix issues without breaking existing functionality.

Build mobile-first responsive layouts with fluid containers, relative units, standard breakpoints, and touch-friendly design that adapts seamlessly across devices. Use this skill when creating or modifying layouts, implementing media queries, defining breakpoints, choosing sizing units, optimizing for mobile devices, or testing UI across screen sizes. Apply when working with responsive design, mobile layouts, tablet views, desktop views, viewport configuration, or any styling that needs to adapt to different screen sizes and device capabilities.
Write minimal, focused tests for core user flows and critical paths during development, testing behavior rather than implementation with clear test names and mocked dependencies. Use this skill when writing unit tests, integration tests, test files, test cases for critical workflows, or mocking external dependencies. Apply when working with test files (.test.js, .spec.ts, _test.py), test frameworks (Jest, RSpec, pytest), testing user journeys, or implementing fast-executing tests that validate business-critical functionality without over-testing implementation details or edge cases during feature development.
Guides users on creating mock implementations for testing with traits, providing test doubles, and avoiding tight coupling to test infrastructure. Activates when users need to test code with external dependencies.
Introduces property-based testing with proptest, helping users find edge cases automatically by testing invariants and properties. Activates when users test algorithms or data structures.
Reviews test coverage and suggests missing test cases for error paths, edge cases, and business logic. Activates when users write tests or implement new features.
Test-Driven Development (TDD) using Vitest and TypeScript. Use when the user requests help with TDD, writing tests before code, test-first development, Vitest test setup, TypeScript testing patterns, unit testing, integration testing, or following the Red-Green-Refactor cycle with Vitest.

Structured hypothesis formulation from observations. Use when you have experimental observations or data and need to formulate testable hypotheses with predictions, propose mechanisms, and design experiments to test them.
