Performance Testing in Storybook

Introduction

Performance testing in Storybook helps ensure that your UI components are optimized for speed and responsiveness. This lesson covers how to effectively measure and improve performance within Storybook.

Why Performance Testing?

• Identifies bottlenecks in UI components.
• Ensures fast loading times for better user experience.
• Helps maintain performance standards during development.

Setting Up Performance Testing

To set up performance testing in Storybook, follow these steps:

1. Install performance testing libraries, such as storybook-addon-performance.
2. Configure your Storybook to include the performance addon in the main.js file:

module.exports = {
    addons: [
        'storybook-addon-performance',
    ],
};

Running Performance Tests

To run performance tests for your components:

1. Open Storybook in your browser.
2. Navigate to the component story you want to test.
3. Click on the performance tab to view metrics.
4. Analyze the performance report and identify any potential issues.

// Example of a performance test in a Storybook component
import { PerformanceTest } from 'storybook-addon-performance';


    
 

Best Practices
