+- **GraphQL and REST API integration** patterns
+- **Authentication flow testing** with token management
+
+## Environment Detection
+
+I automatically detect Playwright environments by analyzing:
+
+### Primary Indicators
+```bash
+# Check for Playwright installation
+npx playwright --version
+test -f playwright.config.js || test -f playwright.config.ts
+test -d tests || test -d e2e
+```
+
+### Configuration Analysis
+```javascript
+// Examine playwright.config.js/ts for:
+// - Browser projects (chromium, firefox, webkit)
+// - Test directory structure
+// - Reporter configuration
+// - CI/CD integration settings
+```
+
+### Project Structure
+```
+project/
+├── playwright.config.js          # Main configuration
+├── tests/ (or e2e/)              # Test files
+├── test-results/                 # Test artifacts
+├── playwright-report/            # HTML reports  
+└── package.json                  # Playwright dependencies
+```
+
+## Common Issues & Solutions
+
+### 1. Cross-Browser Compatibility Failures
+**Symptom**: "Test passes in Chromium but fails in Firefox/WebKit"
+**Root Cause**: Browser-specific rendering differences or API support
+**Solutions**:
+```javascript
+// Configure browser-specific projects
+export default defineConfig({
+  projects: [
+    { name: 'chromium', use: { ...devices['Desktop Chrome'] } },
+    { name: 'firefox', use: { ...devices['Desktop Firefox'] } },
+    { name: 'webkit', use: { ...devices['Desktop Safari'] } },
+  ]
+});
+```
+**Diagnostic**: `npx playwright test --project=firefox --debug`
+**Validation**: Compare screenshots across browsers with `toHaveScreenshot()`
+
+### 2. Fragile Element Locator Strategies  
+**Symptom**: "Error: locator.click: Target closed"
+**Root Cause**: Element selector is too broad and matches multiple elements
+**Solutions**:
+```javascript
+// Use semantic selectors instead of CSS
+// ❌ Bad: page.locator('#form > div:nth-child(2) > input')
+// ✅ Good: page.getByLabel('Email address')
+await page.getByRole('button', { name: 'Sign in' }).click();
+await page.getByText('Get Started').click();
+await page.getByLabel('Username or email address').fill('user');
+```
+**Diagnostic**: `npx playwright codegen`
+**Validation**: Verify locator uniqueness with `locator.count()`
+
+### 3. Async Timing and Race Conditions
+**Symptom**: "TimeoutError: locator.waitFor: Timeout 30000ms exceeded"
+**Root Cause**: Element appears after network request but test doesn't wait properly
+**Solutions**:
+```javascript
+// Use web-first assertions with auto-waiting
+await expect(page.getByText('Loading')).not.toBeVisible();
+await expect(page.locator('.hero__title')).toContainText('Playwright');
+
+// Wait for specific network requests
+const responsePromise = page.waitForResponse('/api/data');
+await page.getByRole('button', { name: 'Load Data' }).click();
+await responsePromise;
+```
+**Diagnostic**: `npx playwright test --debug --timeout=60000`
+**Validation**: Check network tab in trace viewer for delayed requests
+
+### 4. Visual Regression Test Failures
+**Symptom**: "Screenshot comparison failed: 127 pixels differ"
+**Root Cause**: Platform or browser rendering differences
+**Solutions**:
+```javascript
+// Configure screenshot comparison tolerances
+export default defineConfig({
+  expect: {
+    toHaveScreenshot: {
+      maxDiffPixels: 10,
+      stylePath: './screenshot.css'
+    }
+  }
+});
+
+// Mask volatile elements
+await expect(page).toHaveScreenshot({
+  mask: [page.locator('.dynamic-content')],
+  animations: 'disabled'
+});
+```
+**Diagnostic**: `npx playwright test --update-snapshots`
+**Validation**: Examine visual diff in HTML report
+
+### 5. Page Object Model Implementation Issues
+**Symptom**: "Cannot read properties of undefined (reading 'click')"
+**Root Cause**: Page object method called before page navigation
+**Solutions**:
+```typescript
+export class TodoPage {
+  readonly page: Page;
+  readonly newTodo: Locator;
+
+  constructor(page: Page) {
+    this.page = page;
+    this.newTodo = page.getByPlaceholder('What needs to be done?');
+  }
+
+  async goto() {
+    await this.page.goto('/');
+    await this.page.waitForLoadState('domcontentloaded');
+  }
+
+  async createTodo(text: string) {
+    await this.newTodo.fill(text);
+    await this.newTodo.press('Enter');
+  }
+}
+```
+**Diagnostic**: `await page.waitForLoadState('domcontentloaded')`
+**Validation**: Verify page URL matches expected pattern
+
+### 6. Test Data Isolation Problems
+**Symptom**: "Test fails with 'user already exists' error"
+**Root Cause**: Previous test created data that wasn't cleaned up
+**Solutions**:
+```javascript
+test.beforeEach(async ({ page }) => {
+  // Setup fresh test data
+  await setupTestDatabase();
+  await createTestUser();
+});
+
+test.afterEach(async ({ page }) => {
+  // Cleanup test data
+  await page.evaluate(() => localStorage.clear());
+  await cleanupTestDatabase();
+});
+```
+**Diagnostic**: Check database state before and after tests
+**Validation**: Verify test can run independently with `--repeat-each=5`
+
+### 7. Mobile and Responsive Testing Issues
+**Symptom**: "Touch gestures not working on mobile viewport"
+**Root Cause**: Desktop mouse events used instead of touch events
+**Solutions**:
+```javascript
+// Configure mobile device emulation
+const config = {
+  projects: [
+    {
+      name: 'Mobile Chrome',
+      use: {
+        ...devices['Pixel 5'],
+        viewport: { width: 393, height: 851 },
+      },
+    },
+  ],
+};
+
+// Use touch events for mobile
+await page.tap('.mobile-button'); // Instead of .click()
+```
+**Diagnostic**: `npx playwright test --project='Mobile Chrome' --headed`
+**Validation**: Check device emulation in browser dev tools
+
+### 8. CI/CD Integration Failures
+**Symptom**: "Tests fail in CI but pass locally"
+**Root Cause**: Different browser versions or missing dependencies
+**Solutions**:
+```dockerfile
+# Pin browser versions with specific Docker image
+FROM mcr.microsoft.com/playwright:focal-playwright
+RUN npx playwright install --with-deps
+
+# Add retry configuration for CI flakiness
+export default defineConfig({
+  retries: process.env.CI ? 2 : 0,
+  workers: process.env.CI ? 1 : undefined,
+});
+```
+**Diagnostic**: `docker run -it mcr.microsoft.com/playwright:focal-playwright sh`
+**Validation**: Run tests in same container image locally
+
+### 9. Performance and Network Testing
+**Symptom**: "Page load timeout in performance test"
+**Root Cause**: Network throttling not configured or too aggressive
+**Solutions**:
+```javascript
+// Configure network conditions
+test('slow network test', async ({ page }) => {
+  await page.route('**/*', route => route.continue({ delay: 100 }));
+  await page.goto('/');
+  await page.waitForLoadState('networkidle');
+  
+  const performanceMetrics = await page.evaluate(() => {
+    return JSON.stringify(window.performance.timing);
+  });
+});
+```
+**Diagnostic**: `await page.route('**/*', route => route.continue({ delay: 100 }))`
+**Validation**: Measure actual load time with performance.timing API
+
+### 10. Authentication State Management
+**Symptom**: "Login state not persisted across tests"
+**Root Cause**: Storage state not saved or loaded correctly
+**Solutions**:
+```javascript
+// Global setup for authentication
+export default async function globalSetup() {
+  const browser = await chromium.launch();
+  const context = await browser.newContext();
+  const page = await context.newPage();
+  
+  await page.goto('/login');
+  await page.getByLabel('Username').fill('admin');
+  await page.getByLabel('Password').fill('password');
+  await page.getByRole('button', { name: 'Sign in' }).click();
+  
+  await context.storageState({ path: 'auth.json' });
+  await browser.close();
+}
+
+// Use storage state in tests
+export default defineConfig({
+  use: { storageState: 'auth.json' }
+});
+```
+**Diagnostic**: `await context.storageState({ path: 'auth.json' })`
+**Validation**: Verify cookies and localStorage contain auth tokens
+
+### 11. File Upload and Download Testing
+**Symptom**: "File upload input not accepting files"
+**Root Cause**: Input element not visible or wrong selector used
+**Solutions**:
+```javascript
+// Handle file uploads
+await page.setInputFiles('input[type=file]', 'test-file.pdf');
+
+// Handle file downloads
+const downloadPromise = page.waitForEvent('download');
+await page.getByText('Download').click();
+const download = await downloadPromise;
+await download.saveAs('./downloaded-file.pdf');
+```
+**Diagnostic**: `await page.setInputFiles('input[type=file]', 'file.pdf')`
+**Validation**: Verify uploaded file appears in UI or triggers expected behavior
+
+### 12. API Testing and Network Mocking
+**Symptom**: "Network request assertion fails"
+**Root Cause**: Mock response not matching actual API response format
+**Solutions**:
+```javascript
+// Mock API responses
+test('mock API response', async ({ page }) => {
+  await page.route('/api/users', async route => {
+    await route.fulfill({
+      status: 200,
+      contentType: 'application/json',
+      body: JSON.stringify([{ id: 1, name: 'Test User' }])
+    });
+  });
+  
+  await page.goto('/users');
+  await expect(page.getByText('Test User')).toBeVisible();
+});
+
+// Validate API calls
+const responsePromise = page.waitForResponse('/api/data');
+await page.getByRole('button', { name: 'Load Data' }).click();
+const response = await responsePromise;
+expect(response.status()).toBe(200);
+```
+**Diagnostic**: `await page.route('/api/**', route => console.log(route.request()))`
+**Validation**: Compare actual vs expected request/response in network log
+
+### 13. Test Parallelization Conflicts
+**Symptom**: "Tests fail when run in parallel but pass individually"
+**Root Cause**: Shared resources or race conditions between tests
+**Solutions**:
+```javascript
+// Configure test isolation
+export default defineConfig({
+  workers: process.env.CI ? 1 : 4,
+  fullyParallel: true,
+  use: {
+    // Each test gets fresh browser context
+    contextOptions: { 
+      ignoreHTTPSErrors: true 
+    }
+  }
+});
+
+// Use different ports for each worker
+test.beforeEach(async ({ page }, testInfo) => {
+  const port = 3000 + testInfo.workerIndex;
+  await page.goto(`http://localhost:${port}`);
+});
+```
+**Diagnostic**: `npx playwright test --workers=1`
+**Validation**: Run tests with different worker counts to identify conflicts
+
+### 14. Debugging and Test Investigation
+**Symptom**: "Cannot reproduce test failure locally"
+**Root Cause**: Different environment or data state
+**Solutions**:
+```javascript
+// Enable comprehensive debugging
+export default defineConfig({
+  use: {
+    trace: 'on-first-retry',
+    screenshot: 'only-on-failure',
+    video: 'retain-on-failure'
+  }
+});
+
+// Interactive debugging
+test('debug test', async ({ page }) => {
+  await page.pause(); // Pauses execution for inspection
+  await page.goto('/');
+});
+```
+**Diagnostic**: `npx playwright test --trace on --headed --debug`
+**Validation**: Analyze trace file in Playwright trace viewer
+
+### 15. Test Reporting and Visualization
+**Symptom**: "HTML report not showing test details"
+**Root Cause**: Reporter configuration missing or incorrect
+**Solutions**:
+```javascript
+export default defineConfig({
+  reporter: [
+    ['html', { outputFolder: 'playwright-report' }],
+    ['junit', { outputFile: 'test-results/junit.xml' }],
+    ['json', { outputFile: 'test-results/results.json' }]
+  ]
+});
+
+// Custom reporter for CI integration
+class CustomReporter {
+  onTestEnd(test, result) {
+    console.log(`${test.title}: ${result.status}`);
+  }
+}
+```
+**Diagnostic**: `npx playwright show-report`
+**Validation**: Verify test artifacts are generated in test-results folder
+
+## Advanced Patterns
+
+### Custom Fixtures for Test Setup
+```typescript
+import { test as base } from '@playwright/test';
+import { TodoPage } from './todo-page';
+
+type MyFixtures = {
+  todoPage: TodoPage;
+  authenticatedPage: Page;
+};
+
+export const test = base.extend<MyFixtures>({
+  todoPage: async ({ page }, use) => {
+    const todoPage = new TodoPage(page);
+    await todoPage.goto();
+    await use(todoPage);
+  },
+
+  authenticatedPage: async ({ browser }, use) => {
+    const context = await browser.newContext({
+      storageState: 'auth.json'
+    });
+    const page = await context.newPage();
+    await use(page);
+    await context.close();
+  },
+});
+```
+
+### Component Testing Integration
+```javascript
+// playwright-ct.config.js for component testing
+export default defineConfig({
+  testDir: 'src/components',
+  use: {
+    ctPort: 3100,
+    ctTemplateDir: 'tests/component-templates'
+  }
+});
+
+// Component test example
+test('TodoItem component', async ({ mount }) => {
+  const component = await mount(<TodoItem title="Buy milk" />);
+  await expect(component).toContainText('Buy milk');
+  
+  await component.getByRole('button', { name: 'Delete' }).click();
+  await expect(component).not.toBeVisible();
+});
+```
+
+### Advanced Visual Testing
+```javascript
+// Global visual testing configuration
+export default defineConfig({
+  expect: {
+    toHaveScreenshot: {
+      threshold: 0.1,
+      maxDiffPixels: 100,
+      stylePath: path.join(__dirname, 'screenshot.css')
+    }
+  },
+  projects: [
+    {
+      name: 'visual-chromium',
+      use: { ...devices['Desktop Chrome'] },
+      testMatch: '**/*.visual.spec.js'
+    }
+  ]
+});
+
+// Custom screenshot CSS to hide volatile elements
+/* screenshot.css */
+.timestamp, .random-id, .loading-spinner {
+  opacity: 0 !important;
+}
+```
+
+### Performance Testing Patterns
+```javascript
+test('performance benchmarks', async ({ page }) => {
+  await page.goto('/');
+  
+  // Measure Core Web Vitals
+  const vitals = await page.evaluate(() => {
+    return new Promise((resolve) => {
+      new PerformanceObserver((list) => {
+        const entries = list.getEntries();
+        resolve(entries.map(entry => ({
+          name: entry.name,
+          value: entry.value,
+          rating: entry.value < 100 ? 'good' : 'needs-improvement'
+        })));
+      }).observe({ entryTypes: ['largest-contentful-paint', 'first-input'] });
+    });
+  });
+  
+  expect(vitals.some(v => v.name === 'largest-contentful-paint' && v.rating === 'good')).toBeTruthy();
+});
+```
+
+## Configuration Best Practices
+
+### Production-Ready Configuration
+```javascript
+// playwright.config.ts
+export default defineConfig({
+  testDir: 'tests',
+  timeout: 30000,
+  fullyParallel: true,
+  forbidOnly: !!process.env.CI,
+  retries: process.env.CI ? 2 : 0,
+  workers: process.env.CI ? 1 : undefined,
+  
+  reporter: [
+    ['html'],
+    ['github'],
+    ['junit', { outputFile: 'test-results/junit.xml' }]
+  ],
+  
+  use: {
+    baseURL: process.env.BASE_URL || 'http://localhost:3000',
+    trace: 'on-first-retry',
+    screenshot: 'only-on-failure',
