## 🚀 Quick Start

### 1. Run All Tests (Headless)
```bash
npm run test:e2e
```

**What This Does:**
- Starts dev server automatically
- Runs all 6 analytics dashboard tests
- Generates HTML report
- Takes screenshots on failure

**Expected Output:**
```
Running 6 tests using 1 worker
  ✓ HITL Analytics Dashboard - Route and Load (2.3s)
  ✓ Component Metrics Dashboard - Route and Load (1.8s)
  ✓ Recommendation Feedback Dashboard - Route and Load (1.9s)
  ✓ All Analytics Routes - Navigation Flow (3.2s)
  ✓ Analytics Dashboard - No Console Errors (6.1s)
  ✓ Analytics Dashboard - Lazy Loading Performance (1.2s)

6 passed (17s)
```

**To Enable:** Set up test user authentication (see below)

---

## 🔐 Authentication Setup (Optional - For Full Coverage)

### Step 1: Create Test User
```typescript
// tests/helpers/auth.ts
export async function login(page: Page) {
  await page.goto('http://localhost:3000/#login');
  await page.fill('[name="email"]', process.env.TEST_USER_EMAIL!);
  await page.fill('[name="password"]', process.env.TEST_USER_PASSWORD!);
  await page.click('button[type="submit"]');
  await page.waitForURL('**/');
}
```

### Step 2: Add Environment Variables
```bash
# .env.test
TEST_USER_EMAIL=test@example.com
TEST_USER_PASSWORD=testpassword123
```

### Step 3: Enable Tests
Remove `.skip` from auth-required tests in `analytics-dashboards.spec.ts`

---

## 📊 Test Reports

### HTML Report
```bash
npm run test:e2e:report
```

**Features:**
- Test execution timeline
- Screenshots and videos
- Trace files for debugging
- Failure analysis

### JSON Report
Located at `test-results.json` after test run

## 🎨 Agent Browser CLI Advantages

### Traditional Playwright (75-80% reliability)
```typescript
// Non-deterministic - brittle
await page.click('button:has-text("Submit")');
await page.fill('input[placeholder="Search"]', 'query');
```

**Problems:**
- Text can change
- Selectors break with DOM changes
- Timing issues
- Flaky tests

### Agent Browser Approach (95% reliability)
```typescript
// Deterministic - snapshot-based
const snapshot = await page.snapshot();
// Returns: @e1 = Submit button, @e2 = Search input
await page.click('@e1');
await page.fill('@e2', 'query');
```

**Benefits:**
- Stable element references
- No selector maintenance
- Self-healing tests
- Faster development

## 🛠️ Common Commands

### Run Specific Test
```bash
npx playwright test --grep "HITL Analytics"
```

### Run Tests in Specific Browser
```bash
npx playwright test --project=chromium
```

### Show Test Trace
```bash
npx playwright show-trace test-results/path/to/trace.zip
```

### Update Screenshots
```bash
npx playwright test --update-snapshots
```

### Run Tests in Watch Mode
```bash
npx playwright test --watch
```

---

## 🔧 Troubleshooting

### Dev Server Not Starting
```bash
# Manually start dev server first
npm run dev

# In another terminal, run tests with existing server
npx playwright test
```

### Tests Failing Due to Timing
```typescript
// Increase timeout
test.setTimeout(60000);

// Or add explicit wait
await page.waitForLoadState('networkidle');
```

### Screenshot Directory Missing
```bash
mkdir -p tests/screenshots
```

### Playwright Not Found
```bash
npx playwright install chromium
```
