Today, many people use websites every day. They shop, learn, and work online. So, websites must work fast and without errors. This is why testing is important. Playwright is a tool that helps test websites. If you want to learn this tool, you can start with the Playwright Automation Training. It teaches you how to write tests and run them well.

What is Playwright?

Playwright is a tool made by Microsoft. It helps test web pages. It can test websites on Chrome, Firefox, and Safari. You can use it with many languages like JavaScript, TypeScript, Python, and C #.

Why Use Parallel Testing?

Sometimes, testing takes too much time. If you run one test after another, it is slow. Parallel testing helps fix this. You can run many tests at the same time. This saves a lot of time.

Look at the table below. It shows how time goes down when you run tests in parallel.

You can see how parallel testing saves time.

How to Run Playwright Tests in Parallel?

Playwright makes it simple to run tests in parallel. Here are the steps.

Step 1: Install Playwright

Use this command to install Playwright.

npm install -D @playwright/test

Then, install the browsers.

npx playwright install

Step 2: Write Your Test

Write your test in a file. For example, make a file called example.spec.ts.

Here is a small test.

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

test('Check homepage title', async ({ page }) => {

  await page.goto('https://example.com');

  await expect(page).toHaveTitle('Example Domain');

});

Step 3: Run Tests in Parallel

Playwright runs tests in parallel by default. You can change how many tests run at once. Use the --workers option.

npx playwright test --workers=4

This runs four tests at the same time.

Playwright and JavaScript Training

If you want to learn more, you can join a course. A good course is Playwright with JavaScript Training. It shows you how to write tests with JavaScript. You will also learn how to run tests fast using parallel testing.
