## 🚀 **Quick Start (5 Minutes)**

### **1. Installation**

```bash
npm install playwright-advanced-ml-healer
```

### **2. Import and Use**

```typescript
import { PlaywrightCompatibleHealingPage } from 'playwright-advanced-ml-healer';

test('My self-healing test', async ({ page }) => {
  const healingPage = new PlaywrightCompatibleHealingPage(page);
  
  // Navigate to your app
  await healingPage.goto('https://your-app.com');
  
  // Use semantic selectors - they heal automatically!
  await healingPage.fill('email[type="email"]', 'user@example.com');
  await healingPage.fill('password[type="password"]', 'password123');
  await healingPage.click('login[type="submit"]');
  
  // Verify success
  await expect(page).toHaveURL(/dashboard/);
});
```

### **3. That's It!** 🎉

Your tests now automatically heal when elements change. No more broken selectors!

## 🔧 **18+ Advanced Healing Strategies**

### **1. ID-based Healing** 🆔
```typescript
// Heals: #emai → #email, #passwor → #password
await healingPage.fill('#emai', 'user@example.com');
await healingPage.fill('#passwor', 'password123');
```

### **2. Text-based Healing** 📝
```typescript
// Heals: text="Login" → finds button with "Login" text
await healingPage.click('text="Login"');
await healingPage.click('text="Submit Form"');
```

### **3. Semantic Healing** 💭
```typescript
// Heals: understands meaning and context
await healingPage.click('login[type="submit"]');      // Maps "login" to button
await healingPage.fill('email[type="email"]', 'user@example.com');
```

### **4. Placeholder-based Healing** 📍
```typescript
// Heals: finds elements by placeholder text
await healingPage.fill('input[placeholder*="email"]', 'user@example.com');
await healingPage.fill('input[placeholder*="password"]', 'password123');
```

### **5. Element Type Mismatch Healing** 🔄
```typescript
// Heals: handles incorrect element types in selectors
await healingPage.click('div[type="submit"]');        // Finds button[type="submit"]
await healingPage.fill('span[type="email"]', 'user@example.com'); // Finds input[type="email"]
```

## 🚀 **Playwright-Compatible Interface**

### **Drop-in Replacement**
```typescript
// ❌ Old way:
import { Page } from '@playwright/test';
const page = new Page();

// ✅ New way:
import { PlaywrightCompatibleHealingPage } from 'playwright-advanced-ml-healer';
const healingPage = new PlaywrightCompatibleHealingPage(page);
```

### **All Standard Playwright Methods**
```typescript
// Navigation
await healingPage.goto('https://example.com');
await healingPage.reload();
await healingPage.goBack();
await healingPage.goForward();

// Element Interaction
await healingPage.click('selector');
await healingPage.fill('selector', 'value');
await healingPage.type('selector', 'text');
await healingPage.hover('selector');
await healingPage.dblclick('selector');
await healingPage.check('selector');
await healingPage.uncheck('selector');
await healingPage.selectOption('selector', 'value');

// Waiting
await healingPage.waitForSelector('selector');
await healingPage.waitForLoadState('domcontentloaded');
await healingPage.waitForTimeout(1000);

// Evaluation
const result = await healingPage.evaluate(() => document.title);
const element = await healingPage.$('selector');
const elements = await healingPage.$$('selector');
```

### **Advanced Methods with Healing**
```typescript
// Advanced Element Interactions
await healingPage.dragAndDrop('source', 'target');
await healingPage.dispatchEvent('selector', 'click');

// Advanced Form Handling
await healingPage.setInputFiles('selector', ['file.txt']);
await healingPage.addLocatorHandler('selector', handler);

// Advanced Page Operations
await healingPage.addInitScript(() => console.log('Page loaded'));
await healingPage.addStyleTag({ content: '.highlight { color: red; }' });
await healingPage.addScriptTag({ content: 'console.log("Script added");' });
await healingPage.route('**/*.png', route => route.abort());
await healingPage.exposeFunction('customFn', () => 'Hello World');
await healingPage.exposeBinding('customBinding', (source, ...args) => args);

// Advanced Wait Operations
await healingPage.waitForEvent('popup');
await healingPage.waitForEvent('download');
await healingPage.waitForEvent('request');
await healingPage.waitForEvent('response');

// Advanced Page Management
await healingPage.close();
await healingPage.pause();
await healingPage.setDefaultTimeout(30000);
await healingPage.setDefaultNavigationTimeout(30000);
await healingPage.setExtraHTTPHeaders({ 'X-Custom': 'value' });
```

## 📊 **Advanced Analytics & Insights**

### **Healing Statistics**
```typescript
const stats = healingPage.getHealingStats();
console.log('Total healing requests:', stats.totalRequests);
console.log('Success rate:', stats.successRate + '%');
console.log('Average response time:', stats.averageResponseTime + 'ms');
```

### **Strategy Performance**
```typescript
const strategyStats = stats.strategySuccessRates;
console.log('ID-based healing success:', strategyStats.idBased + '%');
console.log('Text-based healing success:', strategyStats.textBased + '%');
console.log('Semantic healing success:', strategyStats.semantic + '%');
```

## 🎯 **Real-World Usage Examples**

## 🔍 **Troubleshooting & Support**

### **Common Issues**

#### **1. Healing Not Working**
```typescript
// Check if healing is enabled
const stats = healingPage.getHealingStats();
console.log('Healing enabled:', stats.enabled);

// Verify selector format
await healingPage.click('login[type="submit"]'); // ✅ Correct
await healingPage.click('login');                // ❌ Too generic
```

#### **2. Performance Issues**
```typescript
// Enable fast path only
const healingPage = new PlaywrightCompatibleHealingPage(page, {
  fastPathOnly: true,
  timeout: 1000
});

// Check performance metrics
const performance = await healingPage.getPerformanceMetrics();
console.log('Average healing time:', performance.averageHealingTime);
