How does the Factory Pattern improve my tests?

It creates a centralized way to generate mock data with sensible defaults, reducing boilerplate and ensuring consistency across your entire test suite.

Can I use this for GraphQL testing?

Yes, it includes specific patterns for mocking generated GraphQL hooks to simulate different data, loading, and error states in your UI components.

What testing frameworks does this skill support?

This skill primarily focuses on Jest and React Testing Library (specifically the React Native variant) while adhering to universal Test-Driven Development (TDD) principles.

Does it help with TDD workflows?

Absolutely. It provides a clear 'Red-Green-Refactor' workflow and emphasizes writing failing tests before implementation code to ensure 100% requirement coverage.

Security & Testing

Implements robust Jest testing strategies using TDD, factory patterns, and comprehensive mocking techniques for high-quality codebase maintenance.

The testing-patterns skill provides a structured framework for implementing Test-Driven Development (TDD) and behavior-driven testing within Claude Code. It streamlines the creation of maintainable test suites through standardized factory patterns for mock data, custom render functions for complex UI components, and advanced mocking strategies for modules and GraphQL hooks. By prioritizing behavior over implementation details and providing clear templates for test structures, this skill helps developers catch bugs early and ensure consistent application behavior across React and React Native projects.

Key Features

01Custom render utilities to simplify testing components with nested providers and themes.

02Best practice patterns for Jest queries and user interaction simulations.

03Advanced mocking strategies for external modules, analytics, and GraphQL hooks.

04Standardized Factory Pattern for generating consistent mock data and component props.

050 GitHub stars

06Structured TDD workflow guidance (Red-Green-Refactor) for production-grade code.
