- [ ] **High Contrast Mode**: Works with high contrast mode

## Responsive Design Checklist

### Breakpoints and Layouts

- [ ] **Mobile First**: Design starts with mobile and scales up
- [ ] **Breakpoint Coverage**: Works at all defined breakpoints
- [ ] **Layout Adaptation**: Layout adjusts appropriately at each breakpoint
- [ ] **Content Reflow**: Content reflows rather than requiring horizontal scrolling

- **Cross-Browser Testing**: BrowserStack, Sauce Labs

### Automation Setup

```bash
# Install testing dependencies
npm install --save-dev @storybook/react @testing-library/react jest axe-core

# Setup visual regression testing
npm install --save-dev @storybook/addon-storyshots-puppeteer

# Setup accessibility testing
npm install --save-dev jest-axe
```

### Example Test Script

```javascript
import React from 'react';
import { render } from '@testing-library/react';
import { axe } from 'jest-axe';
import Component from './Component';

describe('Component', () => {
  it('should render without errors', () => {
    const { container } = render(<Component />);
    expect(container).toBeTruthy();
  });

  it('should not have accessibility violations', async () => {
    const { container } = render(<Component />);
    const results = await axe(container);
    expect(results).toHaveNoViolations();
  });
});
```

## Continuous Improvement Process
