Playwright Automation: Managing Database Connectivity
To connect to a database using Playwright, you would typically not use Playwright itself for database connectivity. Playwright is primarily a tool for browser automation, allowing you to interact with web pages & web applications.
Here's a general outline of how you might connect to a database using Playwright in a JavaScript/Node.js environment:
1. Install the necessary database library: Depending on the type of database you're using, you'll need to install a corresponding Node.js library.
For example, if you're using PostgreSQL, you might install `pg`:
```bash
npm install pg
```
2. Require/import the database library: In your Node.js script where you're using Playwright, you would also import the database library you installed.
3. Connect to the database: You'll typically need to provide connection details such as host, port, username, password, and database name to connect to your database. - Playwright Automation Online Training
Here's a simple example for PostgreSQL:
```javascript
const { Client } = require('pg');
const client = new Client({
user: 'username',
host: 'localhost',
database: 'mydatabase',
password: 'password',
port: 5432, // Default PostgreSQL port
});
async function connect() {
try {
await client.connect();
console.log('Connected to database');
} catch (error) {
console.error('Error connecting to database', error);
}
}
connect();
```
4. Perform database operations: Once connected, you can execute SQL queries, insert/update data, etc., as needed within your Playwright scripts. - Playwright Automation Testing Hyderabad
Here's a very basic example of how you might combine Playwright with database connectivity to interact with a web application and store some data in a PostgreSQL database:
```javascript
const { chromium } = require('playwright');
const { Client } = require('pg');
const client = new Client({
user: 'username',
host: 'localhost',
database: 'mydatabase',
password: 'password',
port: 5432, // Default PostgreSQL port
});
async function main() {
const browser = await chromium.launch();
const page = await browser.newPage();
await page.goto('https://example.com');
// Interact with the web page using Playwright
// Example: extract data from the page
const title = await page.title();
console.log('Page title:', title);
// Connect to the database
try {
await client.connect();
console.log('Connected to database');
// Insert data into a table
await client.query('INSERT INTO mytable (column1, column2) VALUES ($1, $2)', ['value1', 'value2']);
console.log('Data inserted into database');
} catch (error) {
console.error('Error connecting to database or inserting data:', error);
} finally {
// Close the database connection
await client.end();
console.log ('Database connection closed');
}
await browser.close();
}
main();
```
Remember to replace `'username'`, `'password'`, `'mydatabase'`, etc., with your actual database credentials and database name. Additionally, adjust the SQL query to match your database schema. - Playwright Online Training
