@storybook/test
Advanced tools
The @storybook/test package contains utilities for testing your stories inside play functions.
Install the package by adding the @storybook/test dev dependency:
npm install -D @storybook/test
pnpm add -D @storybook/test
yarn add -D @storybook/test
Note that this package is not an addon, so you don't have to add it to your main.js/main.ts file.
The test package exports instrumented versions of @vitest/spy, @vitest/expect (based on chai), @testing-library/dom and @testing-library/user-event. The instrumentation makes sure you can debug those methods in the addon-interactions panel.
// Button.stories.ts
import { expect, fn, userEvent, within } from '@storybook/test';
import { Button } from './Button';
export default {
component: Button,
args: {
onClick: fn(),
},
};
export const Demo = {
play: async ({ args, canvasElement }) => {
const canvas = within(canvasElement);
await userEvent.click(canvas.getByRole('button'));
await expect(args.onClick).toHaveBeenCalled();
},
};
