To test the functionality of function props in Storybook, you can create a story for the component that uses the function prop and then simulate the function call in the story to see if it works as expected.

Here is an example of how you can test the functionality of a function prop in Storybook:

1. Create a story for the component that includes the function prop. Here is an example of a simple button component that takes a function prop called "onClick":

import React from 'react';
import { Button } from './Button';

export default {
  title: 'Button',
};

export const Default = () => (
  <Button onClick={() => console.log('Button clicked')}>
    Click me
  </Button>
);

1. In the story, simulate the function call by adding a console log statement or any other action that you want to test when the button is clicked.
2. Run Storybook and navigate to the Button story. Click on the button in the Storybook UI to trigger the function prop and see if the expected action is executed.

By following these steps, you can test the functionality of function props in Storybook and ensure that your component behaves as expected when the function prop is called.
