Parallel Testing in Playwright

If you're looking for a way to run parallel tests in Playwright without using Selenium Grid, Playwright Test Runner is a great option. It's built into Playwright and allows you to run tests across multiple browser instances without needing a separate grid infrastructure.

Using Playwright Test Runner

To use Playwright Test Runner, you just need to write your tests using the Playwright API and execute them with the test runner. No additional configurations or grid setup is required.

Here's an example of how to run tests in parallel with Playwright Test Runner:

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

async function runTests() {
  const browser = await chromium.launch();
  const context = await browser.newContext();

  await Promise.all([
    test1(context),
    test2(context),
    test3(context)
  ]);

  await context.close();
}

async function test1(context) {
  const page = await context.newPage();
  
  // Your test logic here
}

runTests().catch(console.error);

In this example, we create a new Chromium browser instance and a new context. We then define multiple individual test functions (like test1, test2, test3) that will be executed concurrently using Promise.all(). Each test function can contain its own set of actions and assertions.

By using Playwright Test Runner's built-in parallel execution capabilities, you can achieve efficient and scalable parallel testing without needing a separate grid infrastructure like Selenium Grid.
