What is React Hooks Testing Library?

React Hooks Testing Library is a testing utility for React components that use hooks, making it easier to test their behavior.

How do I set it up in my project?

You can install it via npm with npm install @testing-library/react-hooks. Then, you can import it in your test files.

Can you give me an example of a test using it?

Sure! Here's a simple example:

import { renderHook } from '@testing-library/react-hooks';
import useCounter from './useCounter';

test('should increment counter', () => {
  const { result } = renderHook(() => useCounter());
  act(() => {
    result.current.increment();
  });
  expect(result.current.count).toBe(1);
});

What are some common hooks I can test?

You can test custom hooks like useState, useEffect, and any other hooks you create for your components.
