How can I effectively test hooks in my React application?

You can test hooks using libraries like React Testing Library or Enzyme. Would you like a code example?

Yes, please provide a code example for testing a custom hook.

Sure! Here's a simple example of testing a custom hook using React Testing Library:

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

test('should return expected value', () => {
  const { result } = renderHook(() => useCustomHook());
  expect(result.current).toBe(expectedValue);
});

What about testing side effects in hooks?

For testing side effects, you can use the act function from React Testing Library to ensure updates are processed correctly.
