## Getting Started

### Prerequisites
- Node.js 16+
- WordPress with HVAC plugin installed
- Access to staging environment or local WordPress setup

### Installation

1. **Install Dependencies**
```bash
cd tests/
npm install
```

2. **Environment Setup**
```bash
# For staging environment
export HVAC_TEST_ENV=staging

# For local development
export HVAC_TEST_ENV=local
```

3. **Initialize Framework**
```bash
npm run framework:init
```

4. **Generate Authentication States**
```bash
npm run setup:auth
```

5. **Run Your First Test**
```bash
npm run test:auth
```

### Docker Setup (Optional)

```bash
# Start Docker environment
npm run setup:docker

# Run tests against Docker
HVAC_TEST_ENV=local npm test

# Clean up Docker
npm run teardown:docker
```

## Core Components

### ConfigManager
Centralized configuration management with environment-specific overrides.

```javascript
const ConfigManager = require('./framework/core/ConfigManager');

// Get configuration values
const baseUrl = ConfigManager.get('app.baseUrl');
const timeout = ConfigManager.get('framework.timeout');

// Environment-specific user configs
const trainerConfig = ConfigManager.getUserConfig('trainer');
```

### AuthManager
Sophisticated authentication with storage state pre-generation.

```javascript
const AuthManager = require('./framework/core/AuthManager');

// Authenticate with storage state management
const authResult = await AuthManager.authenticate(page, 'trainer');

// Force fresh login
const authResult = await AuthManager.authenticate(page, 'trainer', { 
    forceLogin: true 
});
```

### BaseTest Class
WordPress-aware test foundation with standardized setup/teardown.

```javascript
const BaseTest = require('./framework/core/BaseTest');

BaseTest.create(
    'should perform WordPress operation',
    async (page, testInfo, baseTest) => {
        // Authenticate
        await baseTest.authenticateAs(page, 'trainer');
        
        // WordPress-specific waits
        await baseTest.waitForWordPress(page, 'ajax');
        
        // WordPress-specific assertions
        await baseTest.assertWordPressState(page, {
            authenticated: true,
            role: 'trainer'
        });
    },
    {
        category: 'functionality',
        priority: 'high',
        tags: ['trainer', 'wordpress']
    }
);
```

### Page Object Models

```javascript
const TrainerDashboard = require('./framework/page-objects/TrainerDashboard');

const dashboard = new TrainerDashboard(page);

// Navigate with WordPress-aware waiting
await dashboard.navigate();

// Verify dashboard elements
await dashboard.verifyDashboard();

// Use dashboard functionality
const stats = await dashboard.getDashboardStats();
await dashboard.goToCreateEvent();
```

## Migration Guide

### Converting Existing Tests

#### Before (Legacy Pattern)
```javascript
const { chromium } = require('playwright');

async function testLogin() {
    const browser = await chromium.launch({ headless: false });
    const page = await browser.newPage();
    
    await page.goto('https://upskill-staging.measurequick.com/training-login/');
    await page.fill('#user_login', 'test_trainer');
    await page.fill('#user_pass', 'TestTrainer123!');
    await page.click('#wp-submit');
    
    // Manual verification...
    await browser.close();
}
```

#### After (Modern Framework)
```javascript
const BaseTest = require('./framework/core/BaseTest');

BaseTest.create(
    'should authenticate trainer successfully',
    async (page, testInfo, baseTest) => {
        // Automatic auth with storage states
        await baseTest.authenticateAs(page, 'trainer');
        
        // WordPress-aware assertions
        await baseTest.assertWordPressState(page, {
            authenticated: true,
            role: 'trainer'
        });
    },
    { category: 'authentication', priority: 'critical' }
);
```

### Migration Steps

1. **Identify Test Categories**
   - Authentication tests → `migrated/auth/`
   - Dashboard tests → `migrated/dashboard/`
   - Event management → `migrated/events/`

2. **Convert Test Structure**
   - Replace manual browser management with `BaseTest.create()`
   - Replace manual authentication with `baseTest.authenticateAs()`
   - Replace manual waits with WordPress-aware waiting

3. **Update Selectors**
   - Use `data-testid` attributes where possible
   - Implement stable selector strategies in page objects

4. **Add Test Metadata**
   - Categorize tests with `category` field
   - Set priority levels (`critical`, `high`, `medium`, `low`)
   - Add relevant tags for filtering

### Migration Script

Use the migration helper:
```bash
npm run migrate:test -- --input=test-login.js --output=migrated/auth/login.modernized.test.js
```

## Configuration

### Environment Variables
```bash
# Environment selection
HVAC_TEST_ENV=staging|local|docker

# Test execution
CI=true                    # Enable headless mode
HEADLESS=true             # Force headless
REGENERATE_AUTH_STATES=true # Force auth state regeneration

# Staging credentials (if needed)
STAGING_ADMIN_PASSWORD=your_password
```

### Configuration Files

**staging.config.js** - Production-like testing
```javascript
module.exports = {
    app: {
        baseUrl: 'https://upskill-staging.measurequick.com'
    },
    testData: {
        seedData: false,        // Don't modify staging data
        cleanupAfterTests: false
    }
};
```

**local.config.js** - Development testing
```javascript
module.exports = {
    app: {
        baseUrl: 'http://localhost:8080'
    },
    browser: {
        headless: false,        // Show browser for debugging
        slowMo: 500
    },
    testData: {
        seedData: true,         // Safe to modify local data
        cleanupAfterTests: true
    }
};
```

## Examples

### Authentication Test
```javascript
BaseTest.create(
    'should authenticate with storage states',
    async (page, testInfo, baseTest) => {
        const authResult = await baseTest.authenticateAs(page, 'trainer');
        
        expect(authResult.valid).toBe(true);
        expect(authResult.method).toBe('storage-state'); // Fast!
        
        await baseTest.assertWordPressState(page, {
            authenticated: true,
            role: 'trainer'
        });
    },
    { category: 'auth', tags: ['storage-state', 'performance'] }
);
```

### Dashboard Navigation Test
```javascript
BaseTest.create(
    'should navigate dashboard sections',
    async (page, testInfo, baseTest) => {
        await baseTest.authenticateAs(page, 'trainer');
        
        const dashboard = new TrainerDashboard(page);
        await dashboard.navigate();
        
        // Test navigation to each section
        await dashboard.navigateToSection('events');
        await dashboard.navigateToSection('profile');
        await dashboard.navigateToSection('venues');
        
        // Verify we can return to dashboard
        await dashboard.navigate();
        await dashboard.verifyDashboard();
    },
    { category: 'navigation', priority: 'high' }
);
```

### Responsive Design Test
```javascript
BaseTest.create(
    'should be mobile responsive',
    async (page, testInfo, baseTest) => {
        await baseTest.authenticateAs(page, 'trainer');
        
        const dashboard = new TrainerDashboard(page);
        
        // Test mobile responsiveness
        const responsive = await dashboard.checkMobileResponsiveness();
        expect(responsive.isMobileResponsive).toBe(true);
        
        // Take comparison screenshots
        await baseTest.takeScreenshot(page, 'dashboard-mobile');
    },
    { category: 'responsive', tags: ['mobile', 'ui'] }
);
```

## Best Practices

### Test Organization
- **One concept per test** - Each test should verify one specific behavior
- **Use descriptive names** - Test names should clearly describe what's being tested
- **Group related tests** - Use `BaseTest.describe()` to group related functionality

### Authentication
- **Use storage states** - Let AuthManager handle authentication automatically
- **Test role boundaries** - Verify users can't access unauthorized areas
- **Test logout** - Ensure logout works and sessions are properly cleared

### WordPress Integration
- **Wait for WordPress** - Use WordPress-aware waiting methods
- **Verify nonces** - Check that WordPress security measures are in place
- **Handle AJAX** - Wait for AJAX requests to complete

### Page Objects
- **Use stable selectors** - Prefer `data-testid` over CSS selectors
- **Implement retry logic** - Handle temporary loading states
- **Provide meaningful errors** - Give clear feedback when elements aren't found

### Error Handling
- **Take screenshots on failure** - Automatically captured by framework
- **Log context** - Include relevant test information in logs
- **Clean up on failure** - Ensure failed tests don't affect subsequent tests

## Troubleshooting

### Common Issues

#### Authentication Failures
```bash
# Regenerate storage states
npm run clean:auth-states
npm run setup:auth

# Use fresh login
FORCE_FRESH_LOGIN=true npm test
```

#### Configuration Issues
```bash
# Validate configuration
npm run health:check

# Export current config for debugging
node -e "console.log(JSON.stringify(require('./framework/core/ConfigManager').getAll(), null, 2))"
```

#### WordPress Connection Issues
```bash
# Test WordPress CLI access
wp --info

# Verify site accessibility
curl -I https://upskill-staging.measurequick.com
```

#### Storage State Issues
```bash
# Clear all storage states
npm run clean:auth-states

# Check storage state status
node -e "
const AuthManager = require('./framework/core/AuthManager');
AuthManager.getAuthStatus().then(console.log);
"
```

### Debug Mode

Enable verbose logging:
```bash
DEBUG=hvac:* npm test
```

Run single test with debug:
```bash
npm run test:debug -- --grep "authentication"
```

### Performance Issues

Check test execution times:
```bash
# View test metrics
cat test-results/test-metrics.jsonl | grep '"duration"'

# Profile slow tests
npm test -- --reporter=json | grep -o '"duration":[0-9]*' | sort -n
```
