How do I optimize my Playwright script for faster performance and reduced loading times?

Answer

Optimize Network Requests

Reducing network latency can speed up your script. Use caching mechanisms or optimize your code to make fewer requests. You can block unnecessary requests, like Google Analytics, by intercepting them:

import { test } from '@playwright/test';

test('Block Google Analytics', async ({ page }) => {
  await page.route('https://www.google-analytics.com/**', (route) => route.abort());
  await page.goto('https://ray.run/');
});

Run in Headless Mode

Running your script in headless mode can significantly reduce resource usage and speed up execution time:

import { test, expect } from '@playwright/test';

test.use({ headless: true });

test('Example test', async ({ page }) => {
  await page.goto('https://ray.run/');
  // Your test code here
});

Optimize Your Code

Review and optimize any inefficient loops or functions. Use asynchronous programming techniques like promises or async/await syntax for non-blocking execution and faster processing times.

Update Playwright

Ensure you're using the latest version of Playwright and keep up-to-date with new releases or updates. These often include bug fixes and performance improvements.

Use Parallelism

Maximize test efficiency by running tests in parallel. Playwright supports parallelism out-of-the-box, and you can control the number of workers using the --workers flag:

npx playwright test --workers=4

By following these tips, you can optimize your Playwright script for faster performance and reduced loading times.
