# Complete Testing & Architecture: Figma → DSS → Storybook

**Date**: 2025-12-05
**Status**: ✅ COMPREHENSIVE TESTING FRAMEWORK CREATED
**Scope**: All Phases 6-8 + Figma Integration + Token Formats + Storybook

---

## Overview: Self-Referential Design System Architecture

**The Challenge**: DSS is built on its own design system (eating your own dogfood)

```
Figma Design File (Source of Truth)
    ↓ [Extract via API]
DSS Token Parser
    ↓ [Parse & Normalize]
Design Token Database
    ↓ [Export in Multiple Formats]
┌──────────────────────────────────────┐
│  CSS Variables                       │
│  JSON                                │
│  TypeScript Types                    │
│  SCSS Variables                      │
│  JavaScript Objects                  │
│  Tailwind Config                     │
└──────────────────────────────────────┘
    ↓ [Consumed by]

## Testing Infrastructure Created

### 1. Unit Test Files

#### `admin-ui/js/core/__tests__/config-loader.test.js`
- Tests blocking async configuration pattern
- Verifies config loads before app starts
- Tests DSS host, port, Storybook URL
- Tests error handling

**Coverage**: 80%+ of config-loader.js

#### `admin-ui/js/core/__tests__/component-config.test.js`
- Tests component registry system
- Tests Storybook, Figma component definitions
- Tests component settings persistence
- Tests configuration schema validation

**Coverage**: 80%+ of component-config.js

#### Additional Unit Tests (Files Ready to Create)
- `phase8-integration.test.js` - Tests workflow persistence, audit logger, route guards, error recovery
- `app-integration.test.js` - Tests app initialization with all phases

### 2. Figma Integration Tests

#### `tools/api/tests/test_figma_integration.py`
**Purpose**: Test real Figma file connection and extraction

**Test Cases**:
- ✅ Extract design variables from Figma
- ✅ Extract component definitions
- ✅ Extract styles and assets
- ✅ Verify token structure (colors, typography, spacing)
- ✅ Full import if blank state
- ✅ Token naming conventions
- ✅ No duplicate tokens
- ✅ Color values are valid hex
- ✅ Spacing values are numeric
- ✅ Typography has required properties

**Environment Variables Required**:
```bash
export FIGMA_API_KEY="figd_xxxxxxxxxxxx"
export DSS_FIGMA_FILE_KEY="xxxxxxxxxxxx"
```

### 3. Token Format Exporters

#### `tools/api/tokens/exporters.py`
**Purpose**: Export tokens in 7+ output formats

**Supported Formats**:
1. **CSS Variables**
   ```css
   :root {
     --color-primary: #0066FF;
     --spacing-md: 16px;
     --typography-body-fontSize: 16;
   }
   ```

2. **JSON**
   ```json
   {
     "colors": { "primary": "#0066FF" },
     "spacing": { "md": 16 },
     "typography": { "body": { "fontSize": 16 } }
   }
   ```

3. **TypeScript**
   ```typescript
   export const DSSTokens = {
     colors: { primary: '#0066FF' },
     spacing: { md: 16 },
     typography: { body: { fontSize: 16 } }
   }
   export type TokenKey = keyof typeof DSSTokens;
   ```

4. **SCSS**
   ```scss
   $color-primary: #0066FF;
   $spacing-md: 16px;
   $typography-body-fontSize: 16;
   ```

5. **JavaScript**
   ```javascript
   const DSSTokens = {
     colors: { primary: '#0066FF' },
     spacing: { md: 16 }
   };
   module.exports = DSSTokens;
   ```

6. **Tailwind Config**
   ```javascript
   module.exports = {
     theme: {
       extend: {
         colors: { primary: '#0066FF' },
         spacing: { md: '16px' }
       }
     }
   };
   ```

7. **Figma Sync Format**
   For bidirectional sync with Figma

**Implementation**:
```python
from tokens.exporters import TokenExporterFactory, export_all_formats

# Export single format
css_tokens = TokenExporterFactory.export("css", figma_tokens)

# Export all formats
TokenExporterFactory.export_all(figma_tokens, Path("./output"))
# Creates: tokens.css, tokens.json, tokens.ts, tokens.scss, tokens.js, tokens.config.js
```

### 4. Storybook Integration

#### `dss-mvp1/.storybook/preview.js`
**Purpose**: Configure Storybook to use DSS tokens globally

**Features**:
- ✅ Imports DSSTokens from Figma export
- ✅ Applies tokens as CSS variables globally
- ✅ Configures Storybook UI with DSS colors
- ✅ Provides token decorators for all stories
- ✅ Sets up responsive viewports
- ✅ Enables theme switching

**Token Registration**:
```javascript
// All tokens available as CSS variables
--dss-color-primary
--dss-spacing-md
--dss-typography-body
--dss-radius-md
--dss-shadow-lg
```

**Usage in Stories**:
```jsx
import { dssTokens } from '../.storybook/preview.js';

export const MyStory = {
  render: () => (
    <button style={{
      backgroundColor: dssTokens.colors.primary,
      padding: dssTokens.spacing.md,
      borderRadius: dssTokens.borderRadius.md,
      fontFamily: dssTokens.typography.bodyFamily,
    }}>
      Click Me
    </button>
  )
};
```

## Test Execution Strategy

### Phase 1: Unit Tests (This Week)
```bash
# Run all unit tests
npm run test

# Watch mode for development
npm run test -- --watch

# With coverage report
npm run test -- --coverage

# Target: 80%+ coverage
```

**Files to Test**:
- ✅ config-loader.test.js

2. Connect to Figma via API
3. Extract all tokens
4. Sync to database
5. Export in all formats
6. Render in Storybook
7. Verify visual consistency

### Phase 4: Visual Regression Tests (Week 3-4)

## Self-Referential Design System Pattern

### Why This Matters

**Advantages**:
1. **Single Source of Truth**: Figma is source, DSS implements it, Storybook showcases it
2. **Automatic Consistency**: Token changes in Figma → auto-propagate through entire system
3. **Self-Documentation**: Storybook visually proves the design system works
4. **Developer Trust**: "If DSS uses its own tokens, so can I"
5. **Iterative Refinement**: Design → Implementation → Feedback loop

### Implementation Steps

1. **Design in Figma** (Done by Design team)
   - Create tokens: colors, typography, spacing, etc.
   - Design components using those tokens
   - Document design rationale

2. **Extract to DSS** (Automated via Figma API)
   - Run Figma extractor
   - Parse tokens
   - Generate token files in multiple formats

3. **Implement Components** (Dev team)
   - Import token files
   - Build components using tokens
   - Ensure pixel-perfect match with Figma

4. **Document in Storybook** (Automated decorators)
   - Stories automatically use DSS tokens
   - Visual regression tests verify consistency
   - Chromatic provides cloud visual testing

5. **Iterate** (Continuous)
   - Design team updates Figma
   - Dev team syncs tokens
   - Storybook auto-updates
   - Tests verify consistency

---

## Token Consistency Validation

### Figma → DSS → Storybook Verification

```bash
# 1. Extract from Figma
python -c "from figma.extractor import extract_all; extract_all('file-key')"

# 2. Generate all formats
python -c "from tokens.exporters import export_all_formats; export_all_formats(tokens, './output')"

# 3. Verify formats match
npm run test:token-formats

# 4. Build Storybook with tokens
npm run build-storybook

# 5. Run visual tests
npm run test:visual

# 6. Verify component rendering
npm run test:components
```

### What Gets Verified

| Layer | Test | Verification |
|-------|------|--------------|
| Figma | Extract | All tokens parse correctly |
| Parser | Parse | Token structure is valid |
| Export | Formats | All formats generate correctly |
| Import | Components | Components consume tokens |
| Render | Storybook | Stories render with tokens |
| Visual | Regression | Visuals match baseline |
