What problem does it solve?

Custom hooks encapsulate complex, reusable logic, but testing their behavior in isolation, especially when they interact with props or context, can be challenging. This Skill provides clear patterns for effective hook testing.

Core Features & Use Cases

• Basic Hook Testing: Learn to test simple custom hooks using renderHook from React Testing Library.
• Hooks with Props: Test hooks that accept and react to prop changes.
• Hooks with Context: Verify hooks that consume values from React Context.
• Use Case: Write comprehensive unit tests for your useAuth custom hook, verifying its initial state, login/logout functionality, and correct integration with an authentication context.

Quick Start

Write a test for the useCounter hook in src/hooks/useCounter.js to ensure its increment and decrement functions work correctly.
