### What is Playwright?
Playwright is a modern framework for reliable end-to-end testing across Chromium, Firefox, and WebKit with a single API.
Unlike older tools, Playwright communicates directly with browser developer protocols, enabling **instant execution**, **automatic waiting**, and **isolated browser contexts**.
### Basic Anatomy of a Playwright Test
```typescript
import { test, expect } from '@playwright/test';
test('verify application landing page', async ({ page }) => {
// 1. Navigate to target URL
await page.goto('https://targetqa.com');
// 2. Assert page title
await expect(page).toHaveTitle(/TargetQA/);
});
```
#### Key Concepts to Remember:
1. **`test(name, async ({ page }) => { ... })`**: The entrypoint for every test case.
2. **`page` fixture**: An isolated browser tab created automatically for each test with zero shared state.
3. **`await` keyword**: Web browser operations are asynchronous. Every action (`goto`, `click`, `fill`) must be awaited.
