Testing Pattern Guide

rohitg00/skillkit

Applies proven testing patterns (AAA, Given-When-Then, builders, spies, doubles) to help write maintainable unit, integration, and end-to-end suites, covering structuring, naming, TDD/BDD, and mocks across frameworks like Jest, Vitest, or pytest.

Production Test Automation Skills Library

lambdatest-agent-skills

sickn33/antigravity-awesome-skills

A comprehensive index of 46 production-grade test automation skills, covering E2E, unit, mobile, BDD, and cloud testing across 15+ languages. This skill equips AI coding assistants to act as senior QA architects, generating structured, real-world test code for major frameworks like Playwright, Selenium, Cypress, and Jest. It supports project setup, CI/CD integration, and cross-platform debugging.

Automatic Unit Test Generator

unit-test-generator

JackyST0/awesome-agent-skills

This skill automatically generates comprehensive unit tests based on provided source code. It supports multiple programming languages (Python, JavaScript, Java, Go, Rust) and popular testing frameworks (pytest, Jest, JUnit). Use it to improve code coverage, test boundary conditions, and validate error handling efficiently, saving manual testing time.

JS/TS Stack Trace Analysis Probe

stack-trace-js-probe

opensquilla/opensquilla

This internal utility probes JavaScript or TypeScript stack traces to provide deep diagnostic insights. It identifies potential language-specific checks (e.g., async boundaries, type contracts), generates minimal reproduction commands for environments like Node.js, npm, or Jest, and highlights targeted patch areas for efficient debugging and bug fixing.

Advanced Testing Patterns and Utilities

code-showcase-testing-patterns

sickn33/antigravity-awesome-skills

Provides comprehensive guidelines and utilities for modern unit testing using Jest and React Native. Covers Test-Driven Development (TDD) workflows, Behavior-Driven Development (BDD) principles, advanced mocking strategies for modules and GraphQL hooks, and implementing reusable factory functions for props and data. Use this skill to write robust, maintainable, and highly structured unit tests.

Generate Jest Unit And Integration Tests

sickn33/antigravity-awesome-skills

This skill generates comprehensive unit and integration tests using Jest for JavaScript and TypeScript. It supports advanced testing patterns, including deep mocking, asynchronous handling, snapshot testing, and testing React components with Testing Library. Use it when the user needs to thoroughly validate application logic and behavior.

Generate Vitest Unit And Component Tests

sickn33/antigravity-awesome-skills

This skill generates comprehensive unit and component tests using Vitest, a fast testing framework built for Vite. It supports JavaScript and TypeScript, offering a Jest-compatible API with advanced features like ESM support, HMR, advanced mocking (vi.mock), snapshot testing, and React component rendering. Use it when dealing with unit testing, TDD, or configuring vitest.config.ts.

Generate Comprehensive Code Tests

FlorianBruniaux/claude-code-ultimate-guide

This tool analyzes specified source code files or modules to automatically generate comprehensive and structured test suites. It identifies testable units (functions, classes, methods), adheres to project conventions (like AAA pattern), and ensures high coverage for critical scenarios, including happy paths, boundary edge cases, and error handling. It supports popular frameworks such as Jest, Vitest, and pytest.

Jest Testing Patterns and Utilities

code-showcase-testing-patterns

sickn33/agentic-awesome-skills

This skill covers Jest testing patterns, factory functions, mocking strategies, and TDD workflows. It helps developers write maintainable unit tests, create test factories, and follow the red-green-refactor cycle. Includes guidance on custom render functions, component props factories, data factories, mocking modules and GraphQL hooks, and best practices for test structure and user interaction patterns.

Jest Unit Test Generation

sickn33/agentic-awesome-skills

Generates Jest unit and integration tests for JavaScript or TypeScript projects. Supports mocking, snapshots, async testing, and React component testing. Ideal for verifying code logic, UI interactions, and API behavior using standard testing patterns.

Production Test Automation Skills Library

lambdatest-agent-skills

sickn33/agentic-awesome-skills

A comprehensive index of 46 production-grade test automation skills, covering E2E, unit, mobile, BDD, and cloud testing across 15+ languages.
