io.github.gradio-app/gradio/frontend-unit-testing

Write comprehensive, behaviour-driven unit tests for Gradio frontend Svelte components using Vitest browser mode, Playwright, and the @self/tootils test utilities.

io.github.latitude-dev/latitude-llm/testing

Writing or debugging tests, choosing unit vs integration style, Postgres/ClickHouse tests, regenerating ClickHouse test schema, or exporting test helpers from packages without pulling test code into production bundles.

io.github.affaan-m/ECC/python-testing

Python testing strategies using pytest, TDD methodology, fixtures, mocking, parametrization, and coverage requirements.

io.github.affaan-m/ECC/react-testing

React component testing with React Testing Library, Vitest/Jest, MSW for network mocking, accessibility assertions with axe, and the decision boundary between component tests and Playwright/Cypress end-to-end runs. Use when writing or fixing tests for React components, hooks, or pages.

io.github.mcp-use/mcp-use/openapi-to-mcp

Build and deploy an MCP server from an OpenAPI / Swagger spec using the mcp-use TypeScript SDK. Use this skill whenever the user wants to "turn this OpenAPI spec into an MCP server", "make this API usable from Claude/ChatGPT", "wrap this Swagger doc as MCP tools", "expose this REST API to an LLM", "generate MCP tools from a spec", or pastes/attaches an `openapi.yaml`, `openapi.json`, or `swagger.json` and asks for a Claude-compatible version. Trigger even if the user doesn't say "MCP" — if they describe an existing HTTP API (REST endpoints, an internal service, a third-party API they have a key for) and want an LLM to call it, this is the right skill. Covers spec ingestion (file path, URL, or pasted), operation-to-tool mapping, auth wiring (apiKey, bearer, basic, OAuth bearer), scaffolding with `create-mcp-use-app`, tool generation with proper zod schemas, live testing in the mcp-use inspector, and deploying to Manufact / mcp-use cloud.

io.github.addyosmani/agent-skills/browser-testing-with-devtools

Tests in real browsers via Chrome DevTools MCP. Use when building or debugging anything that runs in a browser. Use when you need to inspect the DOM, capture console errors, analyze network requests, profile performance, or verify visual output with real runtime data. Requires the chrome-devtools MCP server to be configured.

io.github.alirezarezvani/claude-skills/security-pen-testing

Use when the user asks to perform security audits, penetration testing, vulnerability scanning, OWASP Top 10 checks, or offensive security assessments. Covers static analysis, dependency scanning, secret detection, API security testing, and pen test report generation.

io.github.citypaul/.dotfiles/refactoring

Refactoring assessment and patterns for already-tested code. Use when the user asks to refactor, clean up, simplify, or restructure existing code, and automatically after mutation testing validates test strength (the REFACTOR step of the TDD cycle). Covers commit-before-refactoring discipline, when refactoring adds value vs when to skip it, and the priority classification of improvement opportunities. Do NOT use for untested code (see characterisation-tests and finding-seams first) or for adding behavior (see tdd).

io.github.ag2ai/faststream/testing-patterns

Use when writing or modifying tests under tests/ — base testcase inheritance, pytest markers, fixtures, in-memory vs real-broker testing, and how to run the suite.

io.github.JetBrains/intellij-community/testing

Comprehensive testing reference for running tests in IntelliJ codebase via tests.cmd. Use when running, debugging, or troubleshooting test execution.

io.github.ryoppippi/ccusage/testing

Guides ccusage Rust and Vitest tests. Use when adding or fixing cargo tests, CLI snapshots, Claude model pricing, LiteLLM compatibility, Vitest tests, or fixture-backed tests.

io.github.nexu-io/open-design/agent-browser

Browser automation CLI for AI agents. Use when the user needs to inspect, test, or automate browser behavior: navigating pages, filling forms, clicking buttons, taking screenshots, extracting page data, reading selected Open Design browser-tab context, testing web apps, dogfooding Open Design previews, QA, bug hunts, or reviewing app quality. Prefer local Open Design preview URLs unless the user explicitly asks for external browsing.

io.github.orangehrm/orangehrm/testing

Reference for OrangeHRM's test layers — PHPUnit per-plugin testsuites declared in `phpunit.xml`, the test-DB lifecycle (`instance:create-test-db` builds a populated MySQL DB plus a `CoreFixtureService` dump that bootstrap restores per test), test base classes (`TestCase` for plain unit tests, `KernelTestCase` for tests that need the full framework + DI container, `EntityTestCase` for entity-only tests, `EndpointTestCase` and `EndpointIntegrationTestCase` for API endpoint tests with request mocking + exception expectations), the YAML fixture pattern (per-plugin `test/fixtures/<DaoName>.yml` + `TestDataService::populate($yamlPath)` in `setUp()`), Jest configuration for frontend unit tests (`@vue/cli-plugin-unit-jest/presets/typescript-and-babel`, `__tests__/` siblings), and Cypress for E2E (separate workspace under `src/test/functional/`).
