E2E Testing with Playwright +```javascript +// e2e tests +import { test, expect } from '@playwright/test'; + +test('Alpine.js todo app', async ({ page }) => { + await page.goto('/todo-app'); + + // Test adding a todo + await page.fill('[data-testid="new-todo"]', 'Test todo item'); + await page.click('[data-testid="add-todo"]'); + + await expect(page.locator('[data-testid="todo-item"]')).toHaveText('Test todo item'); + + // Test marking as complete + await page.click('[data-testid="todo-checkbox"]'); + await expect(page.locator('[data-testid="todo-item"]')).toHaveClass(/completed/); +}); +``` + +## Common Troubleshooting + +### 1. Debugging Alpine Components +```html + +
+ +

+
+``` + +### 2. Common Issues and Solutions + +**Issue: x-show not working** +```html + +
Always visible
+ + +
Hidden
+
Conditional
+``` + +**Issue: Event handlers not firing** +```html + + + + + +``` + +**Issue: Reactivity not working** +```javascript +// Wrong: Direct array mutation +this.items[0] = newItem; + +// Correct: Replace array +this.items = [...this.items.slice(0, 0), newItem, ...this.items.slice(1)]; + +// Or use Alpine's $watch for deep watching +this.$watch('items', () => {}, { deep: true }); +``` + +## Advanced Patterns + +### 1.
