Playwright is a powerful tool for browser automation, enabling robust end-to-end testing of web applications. While Playwright itself doesn’t provide built-in database connectivity, you can seamlessly integrate database interactions in your Playwright scripts using additional Node.js libraries. This article will guide you through the steps to connect to a database using Playwright.
Prerequisites
- Node.js and NPM: Ensure you have Node.js and NPM installed on your machine.
- Playwright: Install Playwright by running:
bash
Copy code
npm install playwright
- Database Library: Depending on your database (e.g., MySQL, PostgreSQL, MongoDB), install the respective Node.js library. For example, for MySQL:
bash
Copy code
npm install mysql2
Step-by-Step Guide
1. Setup Project
Create a new directory for your project and navigate into it:
bash
Copy code
mkdir playwright-database-connection
cd playwright-database-connection Playwright Training
Initialize a new Node.js project: Playwright Course Online
bash
Copy code
npm init -y
2. Install Dependencies
Install Playwright and the database library: Playwright Course in Hyderabad
bash
Copy code
npm install playwright mysql2
3. Create Database Connection
Create a new file database.js to handle the database connection:
javascript
Copy code
const mysql = require(‘mysql2’);
const connection = mysql.createConnection({
host: ‘localhost’,
user: ‘your-username’,
password: ‘your-password’,
database: ‘your-database’
});
connection.connect((err) => {
if (err) throw err;
console.log(‘Connected to the database!’);
});
module.exports = connection;
4. Integrate Playwright with Database
Create a Playwright script, test.js, and include database interactions:
javascript
Copy code
const { chromium } = require(‘playwright’);
const db = require(‘./database’);
(async () => {
const browser = await chromium.launch();
const page = await browser.newPage();
// Perform some database operation
db.query(‘SELECT * FROM your_table’, (err, results) => {
if (err) throw err;
console.log(results);
// Use database results in Playwright test
// e.g., navigate to a URL based on database value
page.goto(`http://example.com/${results[0].some_field}`);
});
// Perform browser actions
await page.screenshot({ path: ‘example.png’ });
await browser.close();
db.end();
})();
5. Run Your Script
