Getting Started with Playwright
To start using Playwright, you’ll first need to install it via npm:
“`bash
npm install -g playwright
“`
Once installed, you can create a new test file (e.g., `test.js`) and write your first test using the following example:
“`javascript
const { chromium } = require(‘playwright’);
async function runTest() {
const browser = await chromium.launch();
const page = await browser.newPage();
await page.goto(‘https://www.example.com’);
await page.title();
await browser.close();
}
runTest().catch(console.error);
“`
This example launches a new Chromium browser, navigates to `https://www.example.com`, and logs the title of the webpage before closing the browser.
