Generate Tests

Create or update unit tests for Spark UI components following the project's testing standards.

When to Use

• User wants to add tests to a component
• User mentions "test", "testing", or "test coverage"
• Component is missing tests or has incomplete test coverage

Instructions

1. Test File Location: Tests go in ComponentName.test.tsx in the component directory

2. Testing Library Setup:

   • Use Vitest as the test runner
   • Use React Testing Library for rendering and queries
   • Use @testing-library/user-event for interactions

3. Test Structure:

   import { describe, it, expect } from 'vitest'
   import { render, screen } from '@testing-library/react'
   import userEvent from '@testing-library/user-event'
   import { ComponentName } from './ComponentName'
   
   describe('ComponentName', () => {
     it('should render', () => {
       render(<ComponentName {...defaultProps} />)
       expect(screen.getByRole('...')).toBeInTheDocument()
     })
     
     it('should be accessible', () => {
       // Accessibility tests
     })
   })
   

4. What to Test:

   • Component renders correctly
   • All props work as expected
   • All variants (size, variant, etc.) render correctly
   • User interactions (clicks, keyboard, etc.)
   • Accessibility features (ARIA attributes, roles, etc.)
   • Edge cases and error states

5. Accessibility Testing:

   • Verify proper ARIA attributes
   • Test keyboard navigation
   • Verify focus management
   • Check semantic HTML

6. Run Tests:

   • Use npm run test:ui for watch mode
   • Use npm run test:run for single run
   • Use npm run test:coverage for coverage report

Examples

Reference existing test files in packages/components/src/*/ComponentName.test.tsx for patterns.
