## Implementation Patterns

### Pattern 1: Simple Container Components
```tsx
// BEFORE
function MyComponent({ className, ...props }: ComponentProps<"div">) {
  return <div className={cn("styles", className)} {...props} />
}

// AFTER
function MyComponent({ className, ...props }: ComponentProps<"div">) {
  return (
    <div
      className={cn("styles", className)}
      data-testid="my-component"
      role="region"  // if applicable
      {...props}
    />
  )
}
```

### Pattern 2: Interactive Components
```tsx
// For buttons
<button
  data-testid="component-button"
  aria-label="Action description"
  {...props}
/>

// For input-like elements
<input
  data-testid="component-input"
  aria-label="Input description"
  aria-describedby={errorId}
  {...props}
/>
```

### Pattern 3: Decorative Elements
```tsx
// SVG icons that are decorative
<svg aria-hidden="true">...</svg>

// Spinner/loading indicators
<div aria-busy="true" aria-hidden="true">...</div>

// Purely visual dividers
<hr role="separator" aria-hidden="true" />
```

### Pattern 4: Composite Components
```tsx
// For cards/panels
<div
  data-testid="card-name"
  role="article"  // or "region"
  {...props}
>
  {/* sub-components also get data-testid */}
</div>
```

### Pattern 5: Form Components
```tsx
<div data-testid="form-item">
  <label data-testid="form-label" htmlFor={id}>Label</label>
  <input
    data-testid="form-input"
    id={id}
    aria-describedby={errorId}
    aria-invalid={!!error}
  />
  <p
    id={errorId}
    data-testid="form-error"
    role="alert"
  >
    {error}
  </p>
</div>
```

## Implementation Steps for Remaining Components

1. **Identify root element** - The main component element that represents the component
2. **Add data-testid** - Use kebab-case format matching component name
3. **Add semantic role** - Use appropriate ARIA role (article, region, button, etc.)
4. **Mark decorative elements** - Add `aria-hidden="true"` to visual-only elements
5. **Label interactive elements** - Add `aria-label` to buttons without text content
6. **Link form errors** - Use `aria-describedby` to link inputs to error messages
7. **Update expandable content** - Add `aria-expanded` to collapsible items

## Test IDs Naming Convention

- Container components: `{component-name}` or `{component-name}-wrapper`
- Interactive elements: `{component-name}-{action}` (e.g., `dialog-close-btn`)
- Input fields: `{component-name}-{field-name}`
- Sub-sections: `{component-name}-{section-name}`
- Badges/counts: `{component-name}-{type}-badge`

## Examples by Component Type

### Page/Demo Component
```tsx
data-testid="atoms-section"
data-testid="demo-showcase"
```

### Feature Component
```tsx
data-testid="snippet-card"
data-testid="snippet-editor"
data-testid="namespace-selector"
```

### Settings Component
```tsx
data-testid="database-settings-card"
data-testid="storage-config-card"
```

## Verification Command

To check remaining components needing attributes:
```bash
find src/components -name "*.tsx" ! -name "*.test.tsx" | xargs grep -L "data-testid" | wc -l
```

## Performance Impact

- No performance impact - data-testid attributes are only used by test utilities
- Minimal bundle size increase (< 1KB for all attributes)
- No runtime overhead

## Completion Tracking

Track progress by component category:
- [ ] Sidebar components (12 files)
- [ ] Other UI components (3 files)
- [ ] Feature components (24 files)
- [ ] Layout components (11 files)
- [ ] Atoms/Molecules/Organisms (23 files)
- [ ] Templates/Settings/Demo/Error (19 files)
- [ ] Main components (5 files)

Total: 97 components remaining

## Notes

- Focus on core interactive components first
- Demo/showcase components can be grouped together
- Sidebar components should follow consistent naming
- All modal/dialog-like components should have role="dialog"
- Form-related components should properly link errors with aria-describedby
