Accessibility Attributes Implementation

Standard Pattern for Sections

<section
  className="space-y-6"
  data-testid="component-name-section"
  role="region"
  aria-label="Descriptive text for screen readers"
>
  {/* content */}
</section>

Standard Pattern for Templates

<Card
  className="overflow-hidden"
  data-testid="template-name-template"
  role="main"
  aria-label="Template description"
>
  {/* content */}
</Card>

Standard Pattern for UI Components

<button
  data-testid="component-name"
  aria-label="Button purpose"
  aria-pressed={isActive}
  type="button"
>
  {/* content */}
</button>

Implementation Pattern Examples

Example 1: Atoms Section

export function IconsSection() {
  return (
    <section
      className="space-y-6"
      data-testid="icons-section"
      role="region"
      aria-label="Icon gallery"
    >
      <div>
        <h2 className="text-3xl font-bold mb-2">Icons</h2>
        <p className="text-muted-foreground">
          Phosphor icon set with multiple weights
        </p>
      </div>
      {/* Icon grid content */}
    </section>
  )
}

Example 2: Template

export function DashboardTemplate() {
  return (
    <Card
      className="overflow-hidden"
      data-testid="dashboard-template"
      role="main"
      aria-label="Dashboard template"
    >
      {/* Dashboard content */}
    </Card>
  )
}

Example 3: UI Component

const TopAppBarAction = forwardRef<HTMLButtonElement, TopAppBarActionProps>(
  ({ className, icon, ...props }, ref) => {
    return (
      <button
        ref={ref}
        type="button"
        data-testid="top-app-bar-action"
        data-slot="top-app-bar-action"
        className={/* ... */}
        {...props}
      >
        {icon}
      </button>
    )
  }
)

Verification Steps Completed

  1. ✅ Reviewed all 26 target files
  2. ✅ Verified data-testid attributes exist
  3. ✅ Verified aria-label attributes exist
  4. ✅ Verified role attributes where appropriate
  5. ✅ Ran unit tests - all passing
  6. ✅ Verified no naming conflicts
  7. ✅ Confirmed consistent naming conventions
  8. ✅ Checked semantic HTML structure

Testing Guide

Finding Elements by TestID

// Example test
import { render, screen } from '@testing-library/react';

test('colors section is accessible', () => {
  render(<ColorsSection />);

  const section = screen.getByTestId('colors-section');
  expect(section).toBeInTheDocument();
  expect(section).toHaveAttribute('role', 'region');
  expect(section).toHaveAttribute('aria-label', 'Colors palette');
});

Screen Reader Verification

  • Components can be identified by descriptive testids
  • ARIA labels provide context for screen reader users
  • Semantic roles enable proper navigation
  • All interactive elements are properly labeled

Next Steps

Optional Enhancements

  1. Run automated accessibility audit (axe, WAVE)
  2. Test with screen readers (NVDA, JAWS, VoiceOver)
  3. Verify keyboard navigation flow
  4. Create E2E tests using data-testid selectors
  5. Monitor bundle size impact (minimal)

Maintenance

  • Keep naming conventions consistent
  • Add testids to new components immediately
  • Include aria attributes in new feature PRs
  • Run accessibility checks in CI/CD
